Title

Query formulation in linear retrieval models

Source

Journal of the American Society for Information Science. 41(1990) no.5, S.334-341

Year

1990

Abstract

The subject of query formulation is analysed within the framework of adaptive linear models. The study is based on the notions of user preference and an acceptable ranking strategy. A gradient descent algorithm is used to formulate the query vector by an inductive process. Presents a critical analysis of the existing relevance feedback and probabilistic approaches.
