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…

Diaz, Irene; Morato, Jorge; Llorens, Juan – Journal of the American Society for Information Science and Technology, 2002
Presents a new stemming algorithm based on tree structures that improves relevance in information retrieval by conflation, grouping similar words into a single term. Highlights include the normalization process used in automatic thesaurus construction; theoretical aspects; the normalization algorithm; and experiments with English and Spanish. (LRW)
