Probabilistic Semantic Query Answering on the Web
For many people, the Web has started to play a fundamental role as a means of providing and searching for information and
services. Searching the Web in its current form, however, is not always a joyful experience, since today’s search engines
often are not capable of adequately responding to complex queries. Although the information is available, it is necessary
to go through the cumbersome process of posing multiple simple queries and combining the answers in order to get the desired
response. The next revolution in Web search as one of the key technologies of the Web has just started with the incorporation
of ideas from the Semantic Web, which aims at transforming current Web search into some form of semantic search on the Web
by adding meaning to Web contents and search queries, which also allows for more complex queries, whose evaluation involves
reasoning over the Web. The goal of this project is to develop a family of probabilistic data models for knowledge bases
extracted from the Web, along with scalable query answering algorithms, which may serve as the backbone for such next-generation
technologies for semantic search and query answering on the Web.
