9This is a document search engine with several new visualization front
10ends that aid navigation through the set of documents returned by a
11query. Keywords from the document set are identified and selected on
12the fly. These keywords are then used to compute document clusters. The
13clusters can be displayed and explored using three visualizations:
14Sammon cluster view, Dendro map or radial interactive visualization.<br>
16<h2>Quick start</h2>
17<p>Choose a collection from the colection menu. Type a query into the search box and click the Find button. Each pane will then display the query
18results in a different manner.<br>
20<p style="margin-left: 40px;"><span style="font-weight:bold;">PlainVis</span> ---&nbsp; This shows a ranked list of documents
21retrieved. Clicking on the link for a document (in the left most
22column) will bring up a new window containing the document.<br>
25<p style="margin-left: 40px;"><span style="font-weight: bold;">RadialVis</span> --- This shows the
26key words from the retrieved document set around a circle with the
27documents represented by dots within the circle. The dots are arranged
28closest to the words that contain them. Clicking on a word will
29highlight the documents containing that word. Correspondingly, clicking
30on a dot will show the words that it contains. Words can be dragged
31which will move the dots, thus changing the influence of that particular
32word on the arrangement.<br>
33At the bottom part of the pane key words can be selected and de-selected.<br>
35<p style="margin-left: 40px;"><span style="font-weight: bold;">SammonVis</span> --- This displays
36documents clustered by key words. As you mouse over a cluster a menu is
37displayed. This shows the number of documents in the cluster, and, at
38the bottom of the menu, the top ranked key words used to form the
39cluster. Clicking on the number of documents brings up the key words
40and their percentages in the left hand frame and a summary of the
41documents in the right hand frame. It is possible to drill down two
42levels through this menu. To return to a higher level use the button at
43the top of the frame.<br>
45<p style="margin-left: 40px;"><span style="font-weight: bold;">DendroVis</span> ---&nbsp; This
46displays the document clusters arranged in a hierarchical format. As
47you mouse over nodes in the display a menu similar to the SammonVis
48menu is displayed. You can drill down through the hierarchy to examine
49deeper nodes. The key words are displayed at each node. The menu
50indicates if these are from the outer twigs (bottom) of the hierarchy.
51Clicking on the number of documents in the node displays the keywords
52and document summaries.<br>
