Open Ph.D. position: Focused Web Search
The Database Group of the University of Twente has an opening for a fully
funded four-year PhD position in the Effort project. Effort is a joined
project with the Information and Language Processing Group of the University
of Amsterdam and is financed by the Netherlands Organisation for Scientific
Research (NWO). The project will develop an approach for combining multiple
representations of web information -- such as web directories and specialized
search engines targeting a specific domain -- in a common framework based on
statistical language models. In this framework it will be possible, for
example, to derive models of the actual language-use of web pages to
distinguish between arts, business, entertainment, education, etc. Similarly,
it will be possible to derive models of the structure of web pages to
distinguish between blogs, FAQs, personal web pages, cultural heritage pages,
etc. The envisaged techniques have to be robust to all kinds of errors,
ranging from imperfect information extraction techniques to imprecise queries
formulated by the average web search engine user. An important aspect of any
new technique in a web-setting is that they have to scale up to terabyte-
sized collections. We plan to develop so-called parsimonious models to derive
compact representations and to handle dependencies between representations of
the data. The PhD student will be involved in designing, prototyping and
evaluating such new search solutions. Successful prototypes should be made
available as open source software.
