Faculty Host: W. Bruce Croft

In this lecture, I will talk about three new areas for search, which we are working on at Microsoft Research Asia. They are Relevance of Whole Ranking List, Concept-based Search, and Context-aware Search. I will first explain the fundamental issues of these new areas, and describe the related opportunities and challenges. I will also introduce our recent work for exploring the new frontiers, specifically, global ranking using Continuous CRF (for Relevance of Whole Ranking List), named entity recognition using topic model (for Concept-based Search), and search intent prediction using HMM (for Context-aware Search).
