Concept Detection and Using Concept in Ad-hoc of Microblog Search

Abstract

We report our system and experiments in TREC 2012 microblog Ad-hoc task. Our goal is to return most relevant tweets to satisfy user's information needs which are represented by short keyword queries. In additional to the last year's temporal approach, we used Wikipedia pages to detect concepts of each query. And based on the concepts we detected, we did query expansion and concepts weighting separately. Both methods showed improvements comparing to baseline.
