Searching Spoken Word Collections (28 Feb 2003)
Spoken word collections promise access to unique and compelling content, and most of the needed technology to realize that promise is now in place. Decreasing storage costs, increasing network capacity, and easy availability of software to exchange digital audio make possible physical access to spoken word collections at a previously unimaginable scale. Effective support for intellectual access -- the problem of finding what you are looking for -- is much more challenging, however. In this talk I will review the work that has been done on this problem at the Text Retrieval Conferences and the Topic Detection and Tracking evaluations, and I will present some results from a user study comparing present manual and automated approaches to indexing spoken word collections. I will then describe a unique resource, a collection of 116,000 hours of oral history interviews recorded in 32 languages in 67 countries, and explain how we are leveraging an unprecedented manual indexing effort to develop the ability to index similar materials automatically.
