A Multi-dependency Language Modeling Approach to Information Retrieval (original) (raw)

Lecture Notes in Computer Science, 2007

Abstract

This paper presents a multi-dependency language modeling approach to information retrieval. The approach extends the basic KL-divergence retrieval approach by introducing the hybrid dependency structure, which includes syntactic dependency, syntactic proximity dependency and co-occurrence dependency, to describe dependencies between terms. Term and dependency language models are constructed for both document and query. The relevant between a document and a query
