Query Modification through External Sources to Support Clinical Decisions.

摘要

For the Clinical Decision Support Track of TREC 2014, we looked into the effect of modifying queries by adding or removing terms. We considered both automatic and manual query modifications that use either external data sources or a domain expert. While each method gave slightly different results, we discovered that the manual method still performed slightly better among the methods we considered. This is despite the fact that the manual queries were formed through just term removal; no new terms were added.
