Podcast Search Audio Summaries Dataset

This repository contains the dataset used to analyze user preferences of podcast summaries. The study is described in this paper.

We provide all the releasable data:

Queries
Query biased summaries, for both text and audio channels
Automatic transcripts
Relevance and preference judgments

We also release a software package to download the copyrighted content: Audio podcasts (mp3), Manual transcripts.

We address the challenge of extracting "query biased audio summaries" from podcasts to support users in making relevance decisions in spoken document search via an audio-only communication channel. We performed a crowdsourced experiment that demonstrates that transcripts of spoken documents created using Automated Speech Recognition (ASR), even with significant errors, are effective sources of document summaries or "snippets" for supporting users in making relevance judgments against a query. In particular, results show that summaries generated from ASR transcripts are comparable, in utility and user-judged preference, to spoken summaries generated from error-free manual transcripts of the same collection. We also observed that content-based audio summaries are at least as preferred as synthesized summaries obtained from manually curated metadata, such as title and description. We describe a methodology for constructing a new test collection which we have made publicly available.
