Short queries, natural language and spoken documents retrieval: experiments at Glasgow University

By F. Crestani, M. Sanderson, M. Theophylactou and M. Lalmas


This paper contains a description of the methodology and results of the three TREC submissions made by the Glasgow IR group (glair). In addition to submitting to the ad hoc task, submissions were also made to NLP track and to the SDR speech `pre-track'. Results from our submissions reveal that some of our approaches have performed poorly (i.e. ad hoc and NLP track), but we have also had success particularly in the speech track through use of transcript merging. We also highlight and discuss a seemingly unusual result where retrieval based on the very short versions of the TREC ad hoc queries produced better retrieval effectiveness than retrieval based on more `normal' length queries
