Rieh, Soo Young; Xie, Hong – Proceedings of the ASIST Annual Meeting, 2001
Reports on patterns and sequences of query reformulation based on query logs from a Web search engine. Results show that while most query reformulation involves content changes, about 15% of reformulation is related to format modifications. Six patterns of query reformulation emerged as a result of sequence analysis: specified, parallel,…

Toms, Elaine G.; Freund, Luanne – Proceedings of the ASIST Annual Meeting, 2003
Tests the use of questions as a technique in the query specification process. Using a within-subjects design, 48 people interacted with a modified Google interface to solve four information problems in four domains. Half the tasks were entered as typical keyword queries, and half as questions or statements. Results suggest the typical search box…

White, Ryen W.; Jose, Joemon M.; Ruthven, Ian – Information Processing & Management, 2003
A task-oriented, comparative evaluation between four Web retrieval systems was performed; two using query-biased summarization, and two using the standard ranked titles/abstracts approach. Results indicate that query-biased summarization techniques appear to be more useful and effective in helping users gauge document relevance than the…

Moukdad, Haidar; Large, Andrew – Online Information Review, 2001
Describes the results of a transaction log analysis of a Web search engine, WebCrawler, to analyze user's queries for information retrieval. Results suggest most users do not employ advanced search features, and the linguistic structure often resembles a human-human communication model that is not always successful in human-computer communication.…
