Abstract:
Test collections for information retrieval tasks have traditionally assumed that what we are searching for are documents (e.g., Web pages, news stories, or academic documents). Most information that is generated is, however, not in originally generated as part of a document, but rather as what we might refer to as "conversational media" (e.g., email, speech, or instant messaging). In this talk, I'll describe the creation of a spoken word test collection for the the Cross-Language Evaluation Forum (CLEF) cross-language speech retrieval track. I'll illustrate the issues that arise in the creation of such test collections with some of the results that we have obtained from our experiments with that collection. This is joint work with Charles University, the IBM TJ Watson Research Center, the Johns Hopkins University, the Survivors of the Shoah Visual History Foundation, and the University of West Bohemia.
