Improving Entity Ranking for Keyword Queries
John F. Foley, Brendan O’Connor, James W Allan · 2016
Knowledge bases about entities are an important part of modern information retrieval systems. A strong ranking of entities can be used to enhance query understanding and document retrieval or can be presented as another vertical to the user. Given a keyword query, our task is to provide a ranking of the entities present in the collection of interest. We are particularly interested in approaches to this problem that generalize to different knowledge bases and different collections. In the past, this kind of problem has been explored in the enterprise domain through Expert Search. Recently, a dataset was introduced for entity ranking from news and web queries from more general TREC collections.
