CA3: collaborative annotation of audio in academia

We present a collaborative tagging tool for audio streams. We discuss two case studies using this tool: The first case study demonstrates the usefulness of simple tags as metadata. The second case study elaborates issues discovered while allowing students to tag events during a classroom lecture, and methods for aggregating and displaying the collected tags. We conclude with insights into collaborative tagging for data retrieval in content streams.
