We demo an IR system for municipal council meetings only available in video format. The system uses Whisper to turn speech into text. Three IR systems were compared in a user study: BM25/TF-IDF, KNN ranking on MPNet embeddings, and a chatbot prompted with the query and the top k highly ranked passages. Users solved complex information need slightly faster using the chatbot, but did not find the correct answer in 23%, whereas these were always found with the BM25 and KNN rankers. The benefits of the IR system compared to no system were huge: problem solving time dropped from around 2 min to half a minute and the miss rate from 69% to 0%.

摘要

We demo an IR system for municipal council meetings only available in video format. The system uses Whisper to turn speech into text. Three IR systems were compared in a user study: BM25/TF-IDF, KNN ranking on MPNet embeddings, and a chatbot prompted with the query and the top k highly ranked passages. Users solved complex information need slightly faster using the chatbot, but did not find the correct answer in 23%, whereas these were always found with the BM25 and KNN rankers. The benefits of the IR system compared to no system were huge: problem solving time dropped from around 2 min to half a minute and the miss rate from 69% to 0%.
