How Do Named Entities Contribute to Retrieval Effectiveness? [chapter]

Thomas Mandl, Christa Womser-Hacker
2005 Lecture Notes in Computer Science  
In this paper, we report on an analysis on the correlation between the number of named entities present in a topic and the retrieval quality achieved for these topics by retrieval systems within CLEF.  ...  Named entities in topics are a major factor contributing to the quality of retrieval results.  ...  First, we can see a positive correlation for all tasks considered. Named entities support the retrieval also from the perspective of the document language.  ...
