Title: Knowledge Graph and Question Answering
Abstract: The paradigm of information search is undergoing a significant transformation due to the rise of mobile devices. Techniques that can directly answer user questions and help users navigate the answer space are becoming more desired. In this talk, I will give a broad introduction on knowledge graph and question answering problems studied in my lab. Starting with the challenges and issues existing in knowledge graph query processing, I will discuss our efforts in addressing these issues, including schemaless graph querying, user feedback, factoid question benchmark, natural language questions, and query routing in collaborative networks.
