Combining bibliometrics, information retrieval, and relevance theory, Part 2: Some implications for information science
(tf) and inverse document frequency (idf) values, plotted as pennant diagrams, and interpreted according to Sper-ber and Wilson's relevance theory (RT), the results evoke major variables of information science (IS). These include topicality, in the sense of intercohesion and in-tercoherence among texts; cognitive effects of texts in response to people's questions; people's levels of expertise a...
متن کاملCombining bibliometrics, information retrieval, and relevance theory, Part 1: First examples of a synthesis
In Sperber and Wilson's relevance theory (RT), the ratio Cognitive Effects/Processing Effort defines the relevance of a communication. The tf*idf formula from information retrieval is used to operationalize this ratio for any item co-occurring with a user-supplied seed term in bibliometric distributions. The tf weight of the item predicts its effect on the user in the context of the seed term, ...
متن کاملBibliometrics and Information Retrieval: Creating Knowledge through Research Synergies
This panel brings together experts in bibliometrics and information retrieval to discuss how each of these two important areas of information science can help to inform the research of the other. There is a growing body of literature that capitalizes on the synergies created by combining methodological approaches of each to solve research problems and practical issues related to how information...
متن کاملBibliometrics of "Information Retrieval" - A Tale of Three Databases
Coverage is an important criterion when evaluating information systems. This exploratory study investigates this issue by submitting the same query to different databases relevant to the query topic. Information was retrieved f from three databases: ACM Digital Library, WOS (with the Proceedings Citation Index) and Scopus. The search phrase was “information retrieval”, publication years were be...
متن کاملCombining Evidence for Information Retrieval
This study investigated the effect on retrieval performance of two methods of combination of multiple representations of TREC topics. Five separate Boolean queries for each of the 50 TREC routing topics and 25 of the TREC ad hoc topics were generated by 75 experienced online searchers. Using the INQUERY retrieval system, these queries were both combined into single queries, and used to produce ...
