2011 Sense discrimination for physics retrieval
abstract
Information Retrieval in technical domains like physics is characterised by long and precise queries, whose meaning is strongly influenced by term context and domain. We treat this as a disambiguation problem, and present initial findings of a retrieval model that posits a higher probability of relevance for documents matching disambiguated query terms. Preliminary evaluation on a real-life physics test collection shows promising performance improvement.
