Curriculum Vitae

I have a PhD degree in Computer Science from University of Amsterdam. I am currently employed at Yahoo! Research in Barcelona. My current research activities are around access to multimedia content whereas my PhD was about information retrieval from structured documents. [more...]

Post-doc at Yahoo! Research

My post doctoral research at Yahoo! Research has focused mainly on analyzing annotations of multimedia -- primarily using Flickr tags. The research has taken place within two European projects -- Semedia and WeKnowIt.

Flickr tagging

We have performed a large scale analysis of photo annotations -- mainly Flickr tags -- to extract usage patterns that can be exploited to aid the annotation process and to improve the browsing of photos.

PhD at University of Amsterdam

I did my PhD research at the Information and Language Processing Systems (ILPS) group of the Intelligent Systems Lab Amsterdam (ISLA) of the University of Amsterdam. My supervisors were Maarten de Rijke and Jaap Kamps.

PhD Thesis

My thesis is entitled Focused Information Access using XML Element Retrieval. In the thesis I explore how search engines can give additional support to users who are searching a collection of long documents. In such cases the search engine should not only point the user to the appropriate documents but also point the user to the appropriate locations within the documents. I show how this additional support can be realized using XML element retrieval. The core of the thesis involves exhaustive evaluation of XML element retrieval methods.
