Reaction: TileBars: Visualization of Term Distribution Information in Full Text Information Access

The authors start by talking about the problems with visualizing search results. They point out that a lot of information like relative length of documents, frequency, distribution. They further talk about the problems of visualizing so much information. To solve this problem they propose the idea of tilebars.

Tilebars is a visualization involving a set of rectangle whose size depicts the relative length of the result set documents. It uses a gray scale from 0 to 8 to indicate the presence/absence of the query terms. This is achieved by showing tiles inside the rectangle with different gray scales. This kind of visualization also provides information about the distribution of query terms in the document. It also provides better feedback to the user about why a particular document was chosen in the list. Further they have provided features to jump to a particular part of the document by just clicking on the particular tile too.
