Semantic Search at Yahoo!
Peter Mika · 2014
Semantic search refers to a broad array of methods that aim to improve retrieval by interpreting queries beyond the traditional weighted bag of words model of document retrieval. In this talk, we will focus on the subset of these methods that rely on explicit semantic annotations, i.e. linking queries and text to items in a Knowledge Base. We will discuss techniques of entity linking on queries and documents, and the potential impact of these methods on improving performance on the classical ad-hoc document retrieval task. We will also discuss some novel tasks, including entity retrieval and related entity recommendations, and their implementation in Yahoo Search. We will close by considering some of the challenges that are specific to developing search services in a mobile context.
