Drori, Offer., "Using Documents Classification for Displaying Search Results List", Technical Report No. 2002-46 of the Leibniz Center for Research in Computer Science, School of Computer Science and Engineering, Hebrew University of Jerusalem, July 2002

(77) In this paper, we compared four self-developed user interfaces that display document search results using different methods. The two information elements that we used in order to create the four interfaces were document categories and lines from the document. A user study conducted compared our four interfaces. The study showed that the category addition to the interface is beneficial in both objective and subjective measures. It also showed that displaying the relevant lines from the document instead of its first lines increases the effectiveness and shorten the search time in all cases and tasks. The participants liked the interface containing categories and relevant lines better than all other interfaces checked. The search time in this interface was not only perceived as faster by the participants but also was proved faster in the objective manner. Organizing search results using text element enables users to focus on items that are related to search query rather than to browse through the entire displayed search results list. Another sub-research that we conducted, showed that the most important parameter for the users is the confidence level that the answer is accurate; the second parameter in terms of importance is the time of search, and the least important parameter is the feel of comfort while conducting a search.
