Retrieval Group

We work with industry, academia and other government agencies to promote the use of more effective and efficient techniques for manipulating (largely) unstructured textual information.

The group facilitates retrieval research involving large, unstructured text files by providing test collections and organizing the TREC conference and its proceedings. We continue to create new test collections, focusing mainly on collections to support specific information retrieval sub-tasks such as cross-language retrieval and multimedia retrieval. We also develop better evaluation methodology for information access, including improved evaluation measures for comparing systems using test collections and new evaluation measures for interactive searching and browsing operations.
