Using natural language processing to enable in-depth analysis of clinical messages posted to an Internet mailing list: a feasibility study.

Background: An Internet mailing list may be characterized as a virtual community of practice that serves as an information hub with easy access to expert advice and opportunities for social networking. We are interested in mining messages posted to a list for dental practitioners to identify clinical topics. Once we understand the topical domain, we can study dentists' real information needs and the nature of their shared expertise, and can avoid delivering useless content at the point of care in future informatics applications.
