This report is concerned with the Adaptive Filtering and Web tracks. There are separate reports in this volume [1, 2] on the Microsoft Research Redmond participation in QA track and the Microsoft Research Beijing participation in the Web track.. Two runs were submitted for the Adaptive Filtering track, on the adaptive ltering task only (two optimisation measures), and several runs for the Web t...

Overview of the TREC 2011 Web Track

The TREC Web Track explores and evaluates Web retrieval technology over large collections of Web data. In its current incarnation, the Web Track has been active since TREC 2009, where it included both a traditional adhoc retrieval task and a new diversity task [4]. The goal of this diversity task is to return a ranked list of pages that together provide complete coverage for a query, while avoi...

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...

Microsoft Research at TREC 2009: Web and Relevance Feedback Track

We took part in the Web and Relevance Feedback tracks, using the ClueWeb09 corpus. To process the corpus, we developed a parallel processing pipeline which avoids the generation of an inverted file. We describe the components of the parallel architecture and the pipeline and how we ran the TREC experiments, and we present effectiveness results.
