UMass at TREC WEB 2014: Entity Query Feature Expansion using Knowledge Base Links

Entity linking tools predict links between entity mentions in text and knowledge base entries.

We fo-cus on the ad hoc task on the category A subset and demonstrate the benefit of entity-centric approaches even for non-entity queries like “dark chocolate health benefits”.
