Learning to Rank for Information Retrieval and Its Related Applications

Abstract:
Information retrieval has made significant progress in retrieving relevant results for user information need. How to retrieve relevant information more accurately has been one of the important topics in the communities of information retrieval and machine learning. In this talk, I will briefly describe the problem of learning to rank, and share my experience of how to design a learning-based ranking algorithm for the problem. In addition, I will also introduce some related applications to which the learning to rank techniques can be applied, including machine translation, object search, entity search, and recommender system. Furthermore, I will show some emerging search engines in the context of social networking environment.
