PRIS at TREC 2011 Entity Track: Related Entity Finding and Entity List Completion
نویسندگان
چکیده
The group of PRIS focuses on both tasks in Entity Track this year, Related Entity Finding (REF) and Entity List Completion (ELC). This paper reports the approaches to the two tasks. In REF, three points are improved based the method of last two year: building entity lexicons including more information, introducing a distance algorithm between keywords and entities to entity ranking, allocating homepages in a deeper and more reasonable way. The Entity Activation Force (EAF) and Affinity Measure are used in ELC task for completing and reordering the entity list. The evaluation of experimental results shows that the performance is better than previous ones significantly.

This paper describes our participation in the Entity List Completion (ELC) task at Entity track 2011. Our approach combined the work done for the Related Entity Finding 2010 task with some new criteria as the proximity or the similarity between a candidate answer with the correct answers given as examples or their cooccurrences.

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...

The overall aim of the Entity track is to evaluate entity-related searches on Web data. Entity List Completion (ELC) addresses essentially the same task as Related Entity Finding (REF) does: finding entities that are engaged in a specific relation with an input entity. There are two main differences to REF: Entities are not represented by their homepages, but by a unique URI (from a specific co...

This paper gives an overview of our work for the TREC 2010 Entity track. The goal of the TREC Entity track is to study entity-related searches on Web data, which has not been sufficiently addressed in prior research. For both the Related Entity Finding (REF) task and the Entity List Completion (ELC) task in this track, we propose a unified probabilistic framework by incorporating the matching b...

In this paper we describe our submissions to the TREC 2011 Entity Track. We have experimented with several combined approaches to search the entity candidates, i.e.: by resolving the linguistic relation of the given entity, query expansion by e the retrieval results, and ontology approach to identify the named entity from the search result snippets and to retrieved the candidate entity. We rank...
