No one doubts that we have only scratched the surface of what is possible with the Web. The day is coming fast when the Web will become almost a virtual mind reader. Your intent, interests, and needs will be instantly perceived and the information you want will be promptly delivered -- whether you ask for it directly or not -- based on a deep understanding of the meaning of words in your query, knowledge of your preferences and patterns, what others have done before you, your location, and more. In this talk, I will share some of my thoughts about where the Web is heading and how search will be transformed to align to this new Web, laying out some specifics behind Microsoft's vision to empower people with knowledge.

Search is generally a means to the end of finishing a task. While the current search engines are useful to users for finding relevant information, they offer little help to users for further digesting and analyzing the overwhelming found information needed for finishing a complex task. In this talk, I will discuss how statistical topic models can be used to help users analyze and digest the found relevant information and turn search results into actionable knowledge needed to complete a task. I will present several general statistical topic models for extracting and analyzing topics and their patterns in text, and show sample applications of such models in tasks such as opinion integration, comparative summarization, contextual topic trend analysis, and event impact analysis. The talk will conclude with a discussion of novel challenges raised in extending a search engine to an analysis engine that can go beyond search to provide more complete support for users to finish their tasks.
