Keyword extraction and facet analysis for email archives. Kathryn La Barre and Chris Dent have been experimenting with computational methods for creating a faceted access structure of the Unrev-II mailing list archives.
The email archive of the unrev-ii list is the basis for this ongoing project, to build an access tool for an email archive that also functions as a knowledge repository. Methods utilized in future iterations of the project will include traditional semantic analysis, clustering algorithms, and facet analysis. They have a preliminary prototype available, and have published a paper.
