Leveraging Wikipedia Knowledge for Entity Recommendations.

User engagement is a fundamental goal of commercial search engines. In order to increase it, they provide the users an opportunity to explore the entities related to the queries. As most of the queries can be linked to entities in knowledge bases, search engines recommend the entities that are related to the users’ search query. In this paper, we present Wikipedia-based Features for Entity Recommendation (WiFER) that combines different features extracted from Wikipedia in order to provide related entity recommendations. We evaluate WiFER on a dataset of 4.5K search queries where each query has around 10 related entities tagged by human experts on 5-level label scale.
