TREC Microblog 2012 Track: Real-Time Algorithm for Microblog Ranking Systems

by Davide Feltoni Gurini, Fabio Gasparetti
"... As a matter of fact Twitter is becoming the new big data container, due to the deep increase of amount of users and its growing popularity. Moreover the huge amount of user profiles and rough text data, are providing continuosly new research challenges. This paper reports our contribution and result ..."

and results to the Trec 2012 Microblog Track. In this particular, challenge each par-ticipant is required to conduct a ”real-time ” retrieval task, which given a query topic seeks for the most recent and relevant tweets. We devised an effective real time ranking algorithm, avoiding heavy computational

DUTIR at TREC 2011 Microblog Track

by Cunhui Shi, Kejiang Ren, Hongfei Lin, Shaowu Zhang
"... In TREC 2011 Microblog Track, we explore the use of pseudo relevance feedback to expand original query terms in topics. Hyperlink is used to enhance the performance of the retrieval results. And we set a threshold of entropy to filter retrieval results. Microblog is a Realtime Adhoc Task, so we make ..."
