IIIT Hyderabad's CLIR experiments for FIRE-2008

This paper discourses our CLIR experiments performed for the FIRE 1 workshop. We had submitted our runs for Adhoc monolingual document retrieval in Hindi and English, and Ad-hoc cross-lingual document retrieval from Hindi to English, and English to Hindi. In this paper, we describe our English to Hindi and Hindi to English CLIR systems and the experiments conducted on them using the FIRE2008 dataset. We had used a dictionary-based approach of query translation and transliteration of named entities in the queries using a mapping-based, Compressed Word Format(CWF) algorithm[1]. Disjunctive Query formulation with dierent scoring weights based on the part of the topic from which they originated gave us overall better performance.
