PhD position: Deep Web Entity Monitoring

The Database Group of the University of Twente offers a PhD student position in the Dutch national project COMMIT, a 100M Euro project involving 10 universities and 70 companies. The program brings together leading researchers in search engines, parallel computing, databases, interaction in context, embedded systems and knowledge technology.

A large part of the web, the invisible web or deep web, cannot be indexed by web crawlers, for instance dynamic web pages that are returned in response to filling in a web form, or performing a search in a search engine. Instead of crawling deep web data, the approach will monitor web pages for certain (types of) queries. The objective is to develop approaches for monitoring web data that allow users to see a page’s full history of relevant/important changes by identifying entities: people, organizations, products, geographic locations, events, etc. The approach should relate changes in multiple web sites, giving the user a data-warehouse-like overview of the pages they monitor; drilling down to time periods, persons, events, etc.

The research will be done in co-operation with WCC. WCC, started in 1996 and is a successful software company based in Utrecht (NL) and Reston (USA). WCC’s current focus areas are the Employment and Identification Security markets. Both commercial and government customers worldwide use WCC’s smart search & match solutions to support their primary processes. Both WCC and the Database Group of the University of Twente have made significant advances in entity matching and entity ranking applied to for instance Employment Matching and Expert Search. This project will extend this work to monitoring of deep web pages, such a social networking sites, micro-blogging sites, job sites, etc. The candidate will spend part of the time at WCC in Utrecht.
