More Efficient Query-Based Sampling

Decanato - Facoltà di scienze informatiche

Data d'inizio: 7 Settembre 2009

Data di fine: 8 Settembre 2009

The Faculty of Informatics is pleased to announce a seminar given by Almer S. Tigelaar

DATE: Monday, September 7th, 2009

TIME: 11.00

ABSTRACT:
Imagine that we have just a free-form text search field as interface to a search engine, and that we can only parse the results it returns. What can we do to get an idea of what this search engine has to offer content-wise? This is the well known problem of acquiring a resource description when faced with uncooperative servers. We present a new approach to solving this problem, which is less bandwidth intensive compared to previous approaches, such as query-based document sampling.

BIO:
Almer S. Tigelaar is a PhD student at the Database Group of the University of Twente (NL) supervised by Djoerd Hiemstra. His research is aimed at advancing Distributed Information Retrieval. Specifically, he is trying to develop a new approach to the problems in this subfield, based on sound economic principles.

HOST: Prof. Fabio Crestani
