Reaction: TileBars: visualization of term distribution information in full text information access

Document visualization is one of the challenging and hot topics of Information Visualization.

Document visualization turns around two main concepts:

Relevance - what is directly interesting for me
Serendipity - what thing I wasn't searching for could also interest me

Tilebar is certainly an efficient and interesting approach towards document visualization, where we have a rectangle for each document, and each column represents sections(chapters, paragraphs etc.). The frequency is represented using color coding. And each row in the rectangle represents the visulization for a word in the multi-word search query.

This enables us to visualize explicit term distribution information in a full text information access system. The representation simultaenously and compactly indicates relative document length, query term frequency, and query tem distribution.

The Tilebar representation can be easily extended to other media types.Tilebars not only addresses "Relevance" factor but also the "Serendipity" factor.

The paper is certainly a very good read, with helpful diagrams to illustrate the explained concepts.
