The test collection consisted of 1712 papers whose relevance to specific queries had been judged by users. To evaluate the effect of using cocitation data, we calculated for each query two measures of similarity between each relevant paper and every other paper retrieved. Papers were then sorted by the similarity measures, producing two ordered lists. We then compared the resulting predictions of relevance, partial relevance, and non\u2010relevance to the user's evaluations of the same papers. Over\u2010all, the change from the bibliographic coupling measure to the linkage similarity measure, representing the introduction of cocitation data, resulted in better retrieval performance.<\/jats:p>","DOI":"10.1002\/asi.4630310408","type":"journal-article","created":{"date-parts":[[2007,6,28]],"date-time":"2007-06-28T08:16:47Z","timestamp":1183018607000},"page":"278-282","source":"Crossref","is-referenced-by-count":52,"title":["The combined use of bibliographic coupling and cocitation for document retrieval"],"prefix":"10.1002","volume":"31","author":[{"given":"Julie","family":"Bichteler","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"suffix":"III","given":"Edward A.","family":"Eaton","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2007,3,22]]},"reference":[{"key":"e_1_2_1_2_2","first-page":"16","volume-title":"Encyclopedia of Library and Information Science","author":"Weinstock Melvin","year":"1971"},{"issue":"4","key":"e_1_2_1_3_2","first-page":"415","article-title":"Efficacy of Citation Indexing in Reference Retrieval","volume":"12","author":"Huang Theodore S.","year":"1968","journal-title":"Library Resources & Technical Services."},{"issue":"1","key":"e_1_2_1_4_2","first-page":"3","article-title":"Understanding Science by Analysing Its Literature","volume":"10","author":"Cawkell A.
