University of Waterloo at TREC 2010: Legal Interactive

by Mark D. Smucker, Charles L. A. Clarke, Gordon V. Cormack, Olga Vechtomova
"... This year the University of Waterloo (UW) participated in the TREC Legal Interactive track and used the same process as last year except that this year we used three different human operators as opposed to only one as UW did last year. We participated in three topics: 301, 302, and 303. Relative to ..."

unknown title

by Zheng Gao, Rui Bi
"... An ad hoc retrieval task aims at return the most relevant documents based on a particular query. And high precision and recall always depends on clear query and elaborative documents. If the query is ambiguous while document is short and general, common retrieval models may not work well on the feed ..."

That is the main purpose of microblog track of 2014 TREC Conference. The paper describes the first participation of University of Pittsburgh in 2014 TREC microblog track. The data

Do Multiple Listeners to the Public Twitter Sample Stream Receive the Same Tweets?

by Jiaul H. Paik, Jimmy Lin
"... Do multiple listeners to the public Twitter sample stream re-ceive the same tweets? Due to limitations on redistribution of Twitter data, the answer to this question is important for the replicability and reproducibility of research findings. A negative answer creates barriers for different research ..."
