The lecture is one of the most valuable genres of audiovisual data. However, spoken lectures are difficult to reuse because browsing and efficient searching within spoken lectures is difficult. To promote the research activities in the spoken lecture retrieval, this paper reports a test collection for its evaluation. The test collection consists of the target spoken documents of about 2,700 lectures (604 hours) taken from the Corpus of Spontaneous Japanese (CSJ), 39 retrieval queries, the relevant passages in the target documents for each query, and the automatic transcription of the target speech data. We report the retrieval performance targeting the constructed test collection by applying a standard spoken document retrieval (SDR) method, which serves as a baseline for the forthcoming SDR studies using the test collection. We also introduce the several studies conducted by the users of the test collection.
