Czech Information Retrieval with Syntax-based Language Models

In this paper, we deal with information retrieval approach based on language model paradigm, which has been intensively investigated in recent years. We propose, implement, and evaluate an enrichment of language model employing syntactic dependency information acquired automatically from both documents and queries. By testing our model on the Czech test collection from Cross Language Evaluation Forum 2007 Ad-Hoc track, we show positive contribution of using dependency syntax in this context.
