Query Clustering Using Content Words and User Feedback

Ji-Rong Wen, HongJiang Zhang, Jian-Yun Nie

Abstract: Query clustering is crucial for automatically discovering frequently asked queries (FAQs) or most popular topics on a question-answering search engine. Due to the short length of queries, the traditional approaches based on keywords are not suitable for query clustering. This paper describes our attempt to cluster similar queries according to their contents as well as the document click information in the user logs.
