Title
KB-Enabled Query Recommendation for Long-Tail Queries
Abstract
In recent years, query recommendation algorithms have been designed to provide related queries for search engine users. Most of these solutions, which perform extensive analysis of users' search history (or query logs), are largely insufficient for long-tail queries that rarely appear in query logs. To handle such queries, we study a new solution, which makes use of a knowledge base (or KB), such as YAGO and Freebase. A KB is a rich information source that describes how real-world entities are connected. We extract entities from a query, and use these entities to explore new ones in the KB. Those discovered entities are then used to suggest new queries to the user. As shown in our experiments, this approach provides better recommendation results for long-tail queries than existing solutions. We have also incorporated caching to improve the efficiency of our solutions; experimentally, query suggestion can be completed within 100ms. We further propose a framework that integrates our solution with existing query recommendation algorithms. This solution provides the best recommendation results for any query, regardless of whether it is a long-tail query or not. Due to its high performance and efficiency, the solution can support online query recommendation.
