Faceted Navigation – Explorit Everywhere!’s Coolest New Feature
In a January Sneak Peek blog article Darcy gave us a preview of some of what my engineers were working on. Now, I am excited to present to you faceted navigation, one of the coolest ever features added to Explorit Everywhere!
In an excerpt from Peter Morville’s Search Patterns (a classic on designing effective search focused User Interfaces published in 2010), Morville quotes Professor Marti Hearst (from UC Berkeley) as saying,
“Faceted Navigation is arguably the most significant search innovation of the past decade.”
Morville describes faceted navigation simply: “It features an integrated, incremental search and browse experience that lets users begin with a classic keyword search and then scan a list of results” (p. 95).
Our faceted navigation, combined with our clustering technology offers the researcher a more refined approach for zooming in to find the most relevant results from their search. When reviewing the cluster facets, which show other related terms to the search query, the researcher can narrow their results by selecting a Topic. With the Topic selected, the clusters are refreshed using those associated Topic results, and the researcher is presented with new facets only related to that selected Topic. It cuts out the noise, and allows the user to review very specific results.
Let’s now take a look at how faceted navigation works on one of our customer solutions at the University of the Arts, London.
We will start with a search for “Michelangelo” which returns 2,785 results (See Figure 1 above). And in the Topics list of clusters, we can see that there are several related topics: Art, Artist, Design, Sistine Chapel, David, Analysis, and so forth. These topics were derived from the results metadata returned from the 50 databases searched simultaneously.
By selecting the topic facet Sistine Chapel, the cluster facets were re-generated using the 81 results for that topic (See Figure 2). With this new view of the selected results, we now see more specific topics related primarily to Michelangelo’s Sistine Chapel. While the topic of Ceiling Frescos looks interesting, I am curious to focus on the images under the facet Document Type.
As the researcher explores their results, our faceted navigation generates “bread crumbs” that record the drill-down of steps taken. In Figure 3, we see the trail of selections we have made so far. Clicking on > Sistine Chapel will let me step back up, and step down into the Ceiling Frescos when I want to. See Figure 4 below for some of the interesting images I found of Michelangelo’s Sistine Chapel.
