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

This is an interesting paper because it explains the differences on performing text retrieval the way they where doing on titles and abstracts, compared to full texts when the information became available.

Since titles and abstracts were shorter than full texts, the information retrieval was performed in a different way. The author introduces the tool called TileBars that performs information retrieval in full texts, but helping the user by providing information about how long was the text, how are the terms distributed among the structure of the document, and provides a way for the user to decide how he wants to perform the search (how many term sets he wants to provide, and the boolean connectors between them).

The tool is a useful because the user can understand how the search was performed, and it will help to refine their searches in order to get better results. Nowadays, whenever we use the search from Google, we need to "trust" on how the search is being performed, and the algorithm is not displayed to the user in a graphic way, so I think that the tool was useful. The paper also provides 3 different examples on how the search is performed using different set terms, and what are the results of the search.
