Towards the Future of Search and Query Answering on the Web

In this talk, I will give an overview of my recent research activities towards future search and query answering technology for the Web. The talk includes an approach to semantic search on the Web, called Serene, which allows for a semantic processing of Web search queries, and for evaluating complex Web search queries that involve reasoning over the Web. It also includes a generalization to semantic search on the Social Web, where the ranking of the search results is based on the preferences of a group of users.
