  • Dr. Sam Keim on saving lives with leading edge medical search

    Dr. Sam Keim is Professor and Chair of the Department of Emergency Medicine at the College of Medicine Tucson, University of Arizona. Dr Keim is a member of Deep Web Technologies’ advisory board and a strong advocate for developing and using technology to save lives.

    Dr. Keim has collaborated with us to bring to fruition a technology that brings a laser focus to federated search in evidence-based medicine applications. This technology greatly streamlines the research process, helping busy clinicians to quickly make the right decision for treating their patients.

    Dr. Keim was kind enough to answer some questions about his brainchild, Explorit Everywhere! EBM. You can read more about this technology in our two-pager.

    Tell us about your background as a physician in emergency medicine.

    I have practiced emergency medicine for thirty years. Most of this time at Banner University of Arizona Medical Center in Tucson, which is a busy level-1 trauma center. We actively train residents in emergency medicine and pediatric-emergency medicine as well as subspecialty fellows, nurses, clinical pharmacists and paramedics.

    What is evidence-based medicine (EBM)? What problem does EBM solve? And, what is the evidence pyramid?

    EBM is the mindful use of modern technology to acquire the best relevant medical information to the bedside to support clinical decision making. A clinical provider that utilizes EBM greatly benefits their patients because they are able to apply the best and latest proven scientific advances! The Explorit Everywhere! EBM Pyramid is our translation of well-described scientifically-proven levels of strength by which different types of information can be “graded.” Answers to clinical questions are not created equal! A clinician should strive to apply the STRONGEST evidence available for every patient. This frequently does not occur because the clinician doesn’t have a tool, like this one, to find the STRONGEST evidence available. Clinicians and patients no longer need to be frustrated by not having access to information about the best therapies and evidence.

    What is behind your passion for EBM?

    My passion is for optimizing patient care and lifelong learning simultaneously through 21st Century technology solutions. Patient care currently suffers because new advancements, even some that are many years old, have not been “found” by today’s clinicians. This must become unacceptable to providers, health systems and patients! The best and latest medical information must be delivered to busy clinicians without undue hardship. Explorit Everywhere! EBM is the tool that does this.

    You’ve dedicated thirty years of research and teaching focused on EBM. And, you’ve co-authored several journal articles about EBM and technology. What are the major takeaways from those articles and from your experience?

    The major takeaways are that 1) delivering patient care informed by the best evidence is not only better for patients but nourishes the clinician’s need for continuous lifelong learning, 2) continued research into improving search and delivery technology is critical, and 3) an effective collaboration between clinicians, software engineers, and library scientists is essential in creating tools, like Explorit Everywhere! EBM.

    Can you expand on your previous answer and tell us how you teach medical students to become better EBM searchers

    We have an innovative medical school curriculum at The University of Arizona College of Medicine that requires medical students to become inquisitive evidence explorers. A superb clinician must first be expert in asking relevant questions. Such as what is the most likely cause of this condition? What is the most likely high-risk alternative? What is the most effective therapy? What is the best estimate of prognosis? What are the potential harmful outcomes of the standard and alternative therapies? What does this all cost? Our medical students have been learning to use federated search for over a decade to drive their information searching for classroom and bedside clinical problems. It works extremely well for both answering the question at hand as well as driving home the differences between truth and fiction. All evidence is not created equal!

    What do you say to the busy medical practitioner who doesn’t see a need for new technology. To them, DynaMed Plus or UpToDate are good enough. And, when you’re not looking, they might go to Google or Wikipedia.

    Electronic textbooks are better than nothing. They’re a small step better than the old-school physicians that are still out there “winging it” with decades-old knowledge. But busy clinicians need to experience choices that are as convenient as the common electronic textbooks. Explorit Everywhere! EBM gives them those convenient choices.

    Best quality evidence and efficiency are two critical goals for EBM researchers. How does Explorit Everywhere! EBM leverage federated search technology to meet these goals?

    Explorit Everywhere! EBM marries state-of-the-art federated search technology with quality filters to deliver a “buffet table” of choices ranging from highest quality to lower quality. Because not all clinical questions have been rigorously answered by leading systematic review organizations, the clinician might need to use other sources. Explorit Everywhere! EBM allows this decision to be made after ONE single search execution. All of the results are there, teed up, without a need to execute another search. This delivers the best quality at a convenience not equaled by any other system.

    How is Explorit Everywhere! EBM an evolution beyond prior technologies?

    It is a profound leap forward because only the highest quality sources are included in the federation. The user, therefore, does not waste time reading and sorting through low impact information and misinformation. With Explorit Everywhere! EBM you are ONLY delivered the gold!

    Who are the best users of Explorit Everywhere! EBM? Clinicians? Medical students? Residents? Medical researchers? Nurses?

    The best users are all clinicians and anyone who needs the best quality medical information and clinical research delivered and understood now. Not an hour or two from now, but now. In a few short minutes of searching and reading. This includes all of my physician, nursing, pharmacy and veterinarian colleagues. Medical students and residents will find that Explorit Everywhere! EBM brings their performance up to top level. Best evidence always trumps “years of experience” so this is a tool that will allow young clinicians to practice medicine at the state-of-the-art!

    Tell us about the collaboration between your University of Arizona Health Sciences Center and Deep Web Technologies? What roles are each party playing?

    Deep Web Technologies is the engineering partner that we need for Explorit Everywhere! EBM to deliver on the dream – best evidence, anywhere, in seconds. The University of Arizona brings EBM and library sciences expertise. All three domains have complexity and are exploding in rapid growth. The dream team requires expertise in all of these domains. We have it right!

    What is your vision of the perfect EBM system?

    The perfect EBM system supports clinical decision making by bringing the best evidence to answer clinical questions, from novice to expert, instantaneously at the point of patient care. It will have advanced analytics and artificial intelligence to continuously learn and further support decision making. Finally, because patient care does occur everywhere, including on streets, sidewalks, jungles and extreme environments, the perfect system must be wireless, mobile and easy to use. I have no doubt that our team will be there soon!

  • Share the Love!

    At DWT, we want to make Explorit Everywhere! easy for our customers to integrate into their workflows. So, we offer hosted and self-hosted solutions, we support desktops, tablets and smartphones on all major browsers, and we make it easy to embed Explorit Everywhere!, well everywhere!


    Our loyal customers have asked how we can help them to promote the “Explorit Everywhere!” solution in their organizations. In this article I’ll introduce some ideas on how you can help to spread the word to your communities. In the next article (or two) I’ll dive into the nuts and bolts of some of the things that your IT staff can do to link to and embed Explorit Everywhere! from your corporate or university website.

    Here are the ideas.

    Promote Explorit Everywhere! in your community outreach. Promote your search solution in your newsletters, blogs and other customer communication. DWT has a regular newsletter that you can subscribe to on our contact form. It notifies readers of our recent blog articles. Those articles might give you ideas for ways of communicating with your search community. In our blog, we periodically include a customer corner which highlights how customers have used Explorit Everywhere! One such article tells about Colorado Technical University’s deployment of federated search in 2016. Another customer corner shares the experiences of the University of the Arts London with Explorit Everywhere! Share your own experiences with your users or be the subject of our next customer corner! One other thing, we occasionally send a README document to customers with updates on new features of Explorit Everywhere! You can forward these documents to your users to keep them abreast of enhancements to your service.

    Link to your Explorit Everywhere! application. Include links from your organizational website, your library’s catalog or home page, your online newsletter site or from anywhere! If your site has a header, footer, or a sidebar template, one of those could be the ideal place to link to your search page.

    Educate your users. Your users and your stakeholders may want to know how federated search meets their needs better than Google and better than discovery services. We have a number of resources to help you educate your users in our Literature Library and in our information specific to enterprise, government, library, life sciences, medical, military, and multilingual users. Resources in our Literature Library include:

    Blog articles that make the case for federated search include:

    And, here are some blog articles about how Explorit Everywhere! works and its features:

    You are more than welcome to reference our resources in your communications resources. And, you may want to point your users to our FAQs and to your application’s help page, found in the About menu on your Explorit Everywhere! home page to learn more about our technology and product features.

    Create search builders. Search builders are the perfect way to customize your users’ search experiences. You can create a custom title, description, and editor info, set the number of collection columns to 1 or 2, choose which collections are searched, and which fields are available. You can create multiple search builders to give different communities of users their own tailored search experience. We’ll discuss search builders in more detail in the next article in this series.

    Embed. It’s the “everywhere” idea behind “Explorit Everywhere!” that makes it easy for your users to run searches from whichever of your webpages they’re on. You can embed our search widget (instructions at http://[yourApplication]/widget.html). Your web designer can easily customize the widget code to match the look-and-feel of your site.

    Link to and embed us in your subject guides. If your library has LibGuide or another subject guide content management system then you can integrate Explorit Everywhere! into your subject guide published content in the same way that you can include links and widgets on your organizational web-site. Read about how University of the Arts London integrated Explorit Everywhere! into their subject guides here.

    Integrate search into your learning management system. This is very similar to the last idea. Anywhere that you can integrate your own content, you can integrate Explorit Everywhere! Read our thoughts about including libraries in learning management systems here.

    Add third-party widgets to your Explorit Everywhere! application. One of our customers has a chat widget that connects users to librarians. The chat widget company provided a little snippet of HTML and Javascript to load the widget. We helped them to add that to their search page. Most widgets will have simple code to embed them anywhere! The Virginia Department of Transportation added a chat widget to their Explorit Everywhere! application. We wrote a little bit about their experience here.

    Those are our ideas. I’ll be blogging some of the techie details for folks who are inclined to dive deeper.

    Finally, please leave us a comment. How have you promoted Explorit Everywhere! in your organization? How can we better support you?

  • George Mason University Launches Search Engine for Open Source Textbooks

    George Mason University (GMU), in collaboration with Deep Web Technologies (DWT), has just launched Mason OER Metafinder. Wikipedia explains that OERs, open educational resources, are “freely accessible, openly licensed text, media, and other digital assets that are useful for teaching, learning, and assessing as well as for research purposes.”

    Mason’s OER Metafinder is the brainchild of Wally Grotophorst, Associate University Librarian for Digital Programs and Systems at George Mason University. Grotophorst explains the motivation behind collaborating with DWT to bring his idea to fruition.

    What we want to do is help faculty identify open resources that they can adopt for the courses–and thereby save the students some money and still provide quality instruction. To support that desire, I had the idea of developing a search engine that would go across the various OER sources and help a curious faculty member quickly see just what sort of things might be available.

    Grotophorst also noted:

    We believe so much in OER that we’re giving small stipends to faculty who want to produce open texts (which we’ll publish through our Mason Publishing imprint). And, the Office of the Provost is also encouraging faculty to adopt OER texts.

    Mason OER Metafinder supports the vision of the Mason Publishing Group, which aims to make textbooks more affordable. Their web page on Open and Affordable Education Resources explains their vision:

    At Mason, we want to make your courses accessible to all students. One way to do that is to reduce the costs of the textbooks and other educational materials you use—and University Libraries can help. We offer support for reducing the cost of textbooks and for making library-licensed e-content available to your students. We’re also ready to help you discover, use or even develop and publish your own open educational resources.

    Mason OER Metafinder searches fifteen of the leading OER repositories with a single query. Users can perform broad queries across all sources or they can search for terms in full record, title, or author(s). They can also specify a date range and narrow their searches to a specific date range.

    A full record search for “calculus” identifies over 322,000 resources and displays the 623 most relevant ones. Results are clustered by topic, author, source, document format, and document type, making it easy to drill down to explore results of a particular type.

    GMU is a long-time customer of DWT. GMU built Mason OER Metafinder using DWT’s “Search Builder” technology, where customers can create a search engine with custom search fields and sources.

    My niece just started her freshman year at UC Davis. She spent $500 on textbooks. Her parents sure hope the OER movement continues to grow!

  • Chemical Research By the Bay

    I just got back from an exhausting but very enjoyable 5 day trip to the Bay Area where, as usual, I crammed in as many activities and meetings as possible.

    I started out visiting a couple of colleges with my college-bound daughter who is planning to major in Biology (I’m sure that she’ll also be taking some chemistry courses as well). Then I visited friends, customers and prospects in my old haunting grounds (I lived in Silicon Valley most of the 80’s and the early 90’s). On Monday night one of my most senior employees drove 3 hours from Paradise (a small lovely town with a very cool name in the foothills of the Sierras) to have dinner with me in Fisherman’s Wharf. We took a cable car (his first in 30 years) to get from downtown to the Wharf area.

    Lest I forget to mention, I did manage to squeeze in an afternoon this past Tuesday (April 4, 2017) at the 253rd National Meeting of the American Chemical Society (ACS). Let me digress for a minute. Speaking at the 253rd meeting of ACS got me curious as to when and where ACS held its first such meeting. So late Friday  afternoon/evening I recruited Grace, Chemistry and Chemical Engineering Librarian at Stanford University to help me answer this question. Although ACS was formed in 1874, the first of these twice a year meetings wasn’t held until August 6-7, 1890 in Newport, RI.

    Back to my talk, I was invited to present the paper – Unique One Stop Access to a Multitude of Chemical Safety Resources to a workshop put on by CHAS (Chemical Health and Safety) Division of ACS. The paper summarized and demonstrated two gateways (a Stanford version and a publicly available version) that my company developed, working closely with Grace, that aggregate Chemical Safety information.

    Please check out the public gateway at:

    http://chemistrygateway.com/chemsafety

    and do send me feedback through the blog on how we can improve the gateway.

    Finally, as I have been reflecting on the work in Chemical Safety that we’ve done it’s become clear that what we’ve done is most of the way towards being a powerful resource to help accelerate Chemical Research in general.

     

  • Why Doesn’t Explorit Everywhere! Bring Back All Results?

    One of the more common questions that I get from prospects and customers alike is why don’t we bring back all results from each of the sources that we federate? Just earlier in the week one of the librarians at one of our newest customers asked this question. I went back to our blog archive and dug up this wonderful blog article that Darcy wrote in 2015 – Getting the Best Results vs. Getting all of the Results and sent it on to our customer. I love it when I can answer a customer or prospect question by sending them a link to a blog article that answers their question.

    So this afternoon I decided to expand a bit on Darcy’s original blog article.

    In an effort at transparency and to inform our users of the status of searching, the user can look at Search Status popup that displays the list of sources searched with the number of results returned and the number of results found at the source (when the source provides this information). This Search Status popup is a link under the progress bar in the upper left hand corner of the Results page – the text of the link indicates the count of all sources involved in the search, e.g., “54 of 54 sources complete.”

    Viewing the Search Status popup, the user can see, for a broad query, e.g., security, that collectively the sources may have available several hundred to thousands of results while we only retrieved up to the first 100 results. It does beg the question of why we can’t bring back all the results.

    So let us for a moment go directly to one of the more popular sources that we federate — PubMed, a very large database of 20 million medical articles (some full-text but mostly just meta-data).

    Doing the following PubMed searches:

         “myocardial infarction”  —  returns 213,186 results

         “myocardial infarction” AND aspirin  — returns 7,395 results

         “myocardial infarction” AND aspirin AND statins  — returns 542 results

    Even with the most specific of the above queries, PubMed still returned 542 results, more results than most users will review, and certainly more than we would like to return from a source. However, we could retrieve the 542 result if we wanted to.

    The above example illustrates one of my main responses to the question – Why do we not bring back all results? – What I say is that instead of focusing on Explorit Everywhere! bringing back more results, the focus should be on users realizing that the issue is to be more precise in their queries so that they are getting the most relevant results. It is not very useful to get all the results if they do not help the user find the answer they are looking for. Doing a broad search like “myocardial infarction” that found 213,186 results is not as helpful as doing a more precise search like “myocardial infarction” AND aspirin AND statins” with its 542 results. In the more precise search, the user is more likely to find a relevant answer.

    In conclusion, when users issue more precise queries, they will find that Explorit Everywhere! returns most or all of the available results at each source, with the results ranked using our secret sauce so the user can quickly and easily find what they were looking for across all available sources. For the case where more results are available at the source and the user needs to examine all results (perhaps they are doing some legal due diligence) then the user can go directly to the source and conduct the search there.

  • Customer Corner – Colorado Technical University

    Editor’s Note: This is a guest article by Michelle Powers, Director of Library Services at Career Education Corporation (CEC). The Colorado Technical University and a number of other schools owned and operated by CEC are Explorit Everywhere! customers.


    In 2015, the librarians of Colorado Technical University wanted to investigate alternative options to our discovery search tool. While we were not unhappy with the system we had in place, we were often stymied by the inability to incorporate competing vendors into the system’s platform and create a truly seamless experience for our students who relied heavily on the ability to search multiple subscription resources at one time.

    In short, we wanted a system that provided results from truly everything we had, based on relevancy, in a completely seamless fashion, through an easy-to-use interface.

    To begin, it’s important to understand that CTU has 3 campuses: 1 online campus which serves students in a completely online environment and 2 ground campuses in which students can access a traditional library facility but rely heavily on the electronic database collection for academic research.

    Each campus has a unique campus portal; therefore, there are 3 separate library portals. There are also some database differences, based on campus programs and other factors.

    Our initial decision criteria included the following:

    • We needed a system that we could implement across multiple campuses—giving our students and faculty who work in multiple campus environments the same experience
    • We needed a system that would allow individual branding for our separate campuses
    • The system needed to work well with a multitude of vendors
    • They system needed to allow us to continue to track database usage from each campus
    • We needed a system that could be embedded into our campus pages, which is behind a firewall and only available to authorized users
    • We needed a system that would not require additional authentication from our students, such as a student ID, after they log onto the campus portals
    • We needed the system to be intuitive for our users
    • The system had to be affordable

    We were at first hesitant to move back to a federated system, which is what we had in place prior to the implementation of the discovery system. Our federated system had burned images in our collective memory of clunky interfaces and groupings of results which confused users. However, after reviewing how Deep Web Technologies met the criteria outlined above we invited Abe to give us a demo.

    We were impressed with Explorit Everywhere!’s easy-to-understand interface, and features like the Search Builder, the ability to categorize resources on the search page, the ability to embed the search widget into our LibGuides, and more. What we liked most about the product though was that it was vendor neutral and promised to incorporate all of our resources in a way our previous system did not.

    In early 2016 we decided to make the switch and launch the Explorit Everywhere! search tool in April at CTU and multiple other institutions owned and operated by CTU’s parent company, Career Education Corporation. This meant an implementation of Explorit Everywhere! on nearly 50 campus portals in less than 3 months!

    Deep Web Technologies’ team provided clear instructions of what needed to be done on our end, met regularly with our IT team and library leadership to ensure our timeline was met, created systems on the back end to allow for our requested search features, and created a method of providing the library with statistics.

    Our launch was astoundingly…. quiet. No upset student responses, no confusion or dismay at the new interface. Our students and faculty took to the new system like fish in water, which reinforced the library’s own opinion that the system was easy to use, and satisfied the needs of our users.

    Abe and his team including Christy Ziemba, Ellee Wilson, and Susan Martin have been awesome at responding to our queries and resolving any situations we’ve encountered with such a massive change.

    The library is still gathering statistics to accurately calculate changes to usage with the implementation of Explorit Everywhere! We did immediately have increased usage in an e-book database that was unavailable through our previous system, and are expecting to find an overall increase in database usage, especially in the other resources unavailable in the previous system

    Librarians smarter and better than me can argue the pros and cons of a federated system vs a discovery system. I can say that our students ultimately benefit by the comprehensive search feature Deep Web Technologies has offered us.

  • Content Neutrality and Discovery Services

    My Biznar alert on Discovery Services recently deposited in my Inbox a link to this ProQuest blog article:  A Guide to Evaluating Content Neutrality in Discovery Services. Although I have written about content neutrality before, most recently in October of 2015, in the blog article: The Last of the Major Discovery Services is Independent no More, because of the ProQuest blog article, I decided to revisit the topic in this blog article.

    The blog article by ProQuest linked above and quoted below, raises my main concern about the content neutralneutrality of Discovery Services (EDS, Primo and Summon) that are owned by companies whose main business is selling content:

    A concern that some libraries may have is that discovery service providers, that are also content providers, have an intent and vested interest to funnel usage to their content. With the success of online services often based on usage metrics and the fact that the content sales model is driven by the “revenue follows usage” mantra, librarians should well be concerned about content neutrality in discovery services from such dual providers.

    Also, in this ProQuest blog article, the author says – “ProQuest and ExLibris reaffirms our commitment to content neutrality in our discovery systems.”

    Nowhere, however, have I been able to find any ProQuest write-up that backs up this claim that their Discovery Services are, in fact, content neutral. As one of our former Presidents, Ronald Reagan, was fond of saying – “trust but verify”. With that said, librarians should verify the content neutrality of their Discovery Services.

    One test that I would encourage my readers to perform who have purchased a Discovery Service or have access to one is the following: Run 10 queries that cover different subject areas and record for each of the top 10 results where each of these top 10 results are coming from (EBSCO, ProQuest or another publisher). If a large percentage of your top 10 results in EDS are EBSCO results or a large percentage of ProQuest results are being returned by Primo or Summon among your top 10 results, then you have a content neutrality problem. I’d love to see your findings as comments to this blog article.

    The NISO Working Group in their Open Discovery Initiative: Promoting Transparency in Discovery report makes a number of recommendations to Discovery Service vendors and librarians to help them evaluate and ensure the content neutrality of a Discovery Service. These recommendations are summarized in ExLibris’ A Guide to Evaluating Content Neutrality in Discovery Systems.

    These recommendations include:

    • Non-discrimination among content providers in how results are generated and relevance ranked.
    • Non-discrimination in how links to results are ordered in a result list or made available via a link resolver. A potential problem might be how duplicate records are treated by the Discovery Service.
    • Provide libraries with options to configure how links are labelled and displayed and how links to meta-data and full-text are provided.

    In the ExLibris’ Guide, they state that “Content neutrality in a discovery system means that students and researchers are equally exposed to the entire wealth of information from all sources.”

    Although, as you might expect, the Discovery Services don’t address the issue that content neutrality is seriously compromised by the inability of their Services to include in their indices ALL of the content that a library has available at the disposal of their students.

    So, in conclusion, if you want to ensure the content neutrality of your institution’s Discovery Solution you should seriously consider an Explorit Everywhere! solution.

    An Explorit Everywhere! solution provides your users with access to all of the content sources your library has licensed, ranked using our own publisher neutral algorithms (see Ranking: The Secret Sauce for Searching the Deep Web), with the display priority of duplicate results configurable. You might also want to include our partner’s Gold Rush publisher neutral link resolver.

  • Explorit Everywhere! has Become More Accessible

    To make Explorit Everywhere! more accessible, we have leveraged the Web Content Accessible Guidelines 2.0 (WCAG) accessibility guidelines provided by the W3C’s (World Wide Web Consortium—an international standards body to ensure the interoperability between web products. Accessibility refers to making sure that the design of products is usable for the widest range of abilities, such as for persons with different visual abilities, hearing abilities, or physical abilities.

    Often the phrase “Section 508 compliance” is used in conjunction with ensuring accessibility, especially by government agencies. Section 508, which refers specifically to Section 508 of the Rehabilitation Act of 1973, which was amended in 1986, was passed to make sure that the Federal Government provides accessible electronic and information technologies to its employees—including computers, telecommunications, and so on, as well as access to web-based intranet and internet web pages and applications. More recently, though, the Assistive Technology Act of 1998 was passed to make sure that any state that receive Federal funding also adhere to some form of the Section 508 requirement.

    WCAG 2.0 was written specifically for web content and web pages. It also leverages the same goals expressed in Section 508. In the WCAG 2.0, it has three priority levels of checkpoints where Priority 1 checkpoints must be met, Priority 2 should be satisfied, and Priority 3 may be addressed as part of compliance. In Explorit Everywhere!, we have confirmed that we meet most all of Priority 1 when applicable, many of Priority 2, and some of Priority 3 checkpoints. To better understand what changes we have made to meet these checkpoints, I am going to leverage WCAG 2.0’s four fundamental principles: Perceivable, Operable, Understandable, and Robust.

    For the first principle, Perceivable, we have striven to make all components of the user interface evident on our web pages; that is, nothing is hidden. We have also used common iconography rather than inventing new ones that might not be understood so well. For each UI component, we have provided text alternatives, which includes both visual hover-overs on the pages and text alternatives for blind readers. And, based on UX feedback, we have rearranged the structure of the components so that the relationship between them makes more sense to the user or programmatically. Moreover, the meaning of our UI components are not meant to be contextual—that is, they are self-contained, nor are they dependent on color to convey meaning. We do use color contrasts to make the different components stand out more.

    accessibility

    Figure 1: University of the Arts, London, an art school, extends accessibility in their Explorit Everywhere! to support students with different visual needs by offering a selection of color themes and font sizes.

    For our customer University of the Arts, London (UAL), being a specialized school for the arts, we have extended our application even further for their users by offering a selection of color themes for a user to select from, which is then saved to the user’s preferences (see Figure 1). These different options are designed specifically to make the interface more visually perceivable for different visual needs. UAL also asked that we add the ability to resize the text on the web page directly (as opposed to relying on the browser). These functions are available to any customer who wants to further extend their accessibility to offer more support.

    For the Operable principle, we have focused on: keyboard accessibility, timing between functions, and navigable. The most basic operable support is to support keyboard access to all UI components, and to avoid any keyboard traps, that is, getting to a component that cannot be moved away from using the keyboard. Moreover, moving through the components does not require any specific timing for individual keystrokes. And, we have ensured that when initially landing on any page, there is a focused component for commencing keyboard navigation. When applicable, we offer more than one way to view results and to do certain functions since not all users do things the same way. One area for improvement that we intend to implement in the near future is the ability to jump pass entire blocks of content while keyboarding.

    For the third principle, Understandable, we have ensured that Explorit Everywhere! is readable, predictable, and supportive of user involvement. While we believe we have made all the UI components readable and predictable, there is more work to do in making application errors more evident. For readability, we have reduced jargon, kept explanations simple, and avoided abbreviations. Predictability means not letting components randomly change in any way unless initiated by the user. This includes making sure that navigation and UI components are consistent across all functions. We have also expanded user preferences to allow users to save specific UI changes, and we intend to do offer more preferences to users in future releases.

    The last principle, Robust, refers to supporting assistive technologies. Besides extending the keyboard accessibility, we have also reviewed our application in blind readers by making sure that our textual labels both as alt text and as hover-overs are accessible.

    We believe that Explorit Everywhere! is even more perceivable, operable, understandable, and robust than ever!

  • An Innovative Approach to Discovery

    I was pleasantly surprised and pleased when I woke up one recent morning to an email message from Nick Dimant, Managing Director of our partner PTFS Europe. My company and PTFS Europe were partners-in-crime in a unique (hopefully to be repeated many more times) collaboration at the University of the Arts, London (UAL).ual-cilip

    Nick had sent me a copy of – An innovative approach to discovery (available here), a feature article in the June 2016 issue of Update, the monthly magazine of CILIP (Chartered Institute of Library and Information Professionals) by Karen Carden, Resources & Systems Manager, Library Services, UAL and by Jess Crilly, Associate Director, Content and Discovery, Library Services, UAL.

    Carden and Crilly explain in their article in detail their justification and approach to implementing their Library Search solution which “brings together two separate products into (what looks like) a single interface for the user where they can search across our print and e-resources.”

    Carden and Crilly discuss their selection of Explorit Everywhere! back in 2013 (which of course I love) in:

    “After a great deal of research, discussion and testing we opted for an unusual – especially in the UK – next generation federated search tool. Like most libraries in the sector we had experienced first generation federated search, but found that this was quite a different experience.”

    The authors describe UAL as a specialist university. What this means to me is that as a specialist university focused on the arts, a lot of the databases that UAL subscribes to are not mainstream databases and thus not included in the Discovery Services but easily federated by Explorit Everywhere!.

    We give another example in Federating the Unfederatable of a specialist library, this time a defense/international policy focused university where Explorit Everywhere! provides the one-stop discovery of all the sources important to the library patrons, many not available through the Discovery Services.
