Logistic Regression for Metadata: Cheshire Takes on Adhoc-TEL [chapter]

Ray R. Larson
2009 Lecture Notes in Computer Science  
In this paper we will briefly describe the approaches taken by the Berkeley Cheshire Group for the Adhoc-TEL 2008 tasks (Mono and Bilingual retrieval).  ...  In particular, the approach this year used probabilistic text retrieval based on logistic regression and incorporating blind relevance feedback for all of the runs.  ...  Indexing and Term Extraction The Cheshire II system uses the XML structure of the documents to extract selected portions for indexing and retrieval.  ...
