Relevance Propagation for Topic Distillation UIUC TREC 2003 Web Track Experiments

In this paper, we report our experiments on the Web Track TREC-2003. We submitted five runs for the topic distillation task. Our goal was to evaluate the standard language modeling algorithms for topic distillation, as well as to explore the impact of combining link and content information. We proposed a new general relevance propagation model for combining link and content information, and exp...

Meiji University Web and Novelty Track Experiments at TREC 2003

Microsoft Research Asia at the Web Track of TREC 2009

In TREC 2009, we participate in the Web track, and focus on the diversity task. We propose to diversify web search results by first mining subtopics, and then rank results based on mined subtopics. We propose a model to diversify search results by considering both relevance of documents and richness of mined subtopics. Our experimental results show that the model improves diversity of search re...

LIA at TREC 2011 Web Track: Experiments on the Combination of Online Resources

In this paper, we report the experiments we conducted for our participation to the TREC 2011 Web Track. The experiments we conducted this year aim at discovering how the combination of specific external resources in a language modeling fashion can help web search. We use Wikipedia and Google as external resources for different search contexts.
