Abstract:

This paper reports the approaches to the task of Entity Track applied by PRIS lab of BUPT in TREC 2010. We used Document-Centered Model DCM and Entity-Centered Model ECM for the task. BM25 method was introduced into ECM besides indri retrieval model. Another improvement aimed at entity extraction. Special web page, NER tool and entity list generated by some rules were all taken into account. Also, some external resources such as Google and CMU search engine were applied.
