Embedding Term Similarity and Inverse Document Frequency into a Logical Model of Information Retrieval.
Peer reviewed Peer reviewed
Losada, David E.; Barreiro, Alvaro – Journal of the American Society for Information Science and Technology, 2003
Proposes an approach to incorporate term similarity and inverse document frequency into a logical model of information retrieval. Highlights include document representation and matching; incorporating term similarity into the measure of distance; new algorithms for implementation; inverse document frequency; and logical versus classical models of…

Rating News Documents for Similarity.
Peer reviewed Peer reviewed
Watters, Carolyn; Wang, Hong – Journal of the American Society for Information Science, 2000
Discussion of electronic news available on the World Wide Web focuses on a methodology of associating news documents using similarity measures and a name-phrase algorithm to create news representations that can be compared and ranked to find related news items. Considers precision over recall and interactivity with the users. (Author/LRW)
