题 目：Consumer Health Information Searching: Toward Automated, Trustworthy, and Secure Personalization
Searching for health information is one of the most frequent online activities. Unfortunately, the content retrieved often are confusing and contain documents from unreliable sources. To make matters worse, search engines do not employ vocabularies consistently in their representations of content -- during the crawl and indexing process terms as found in source documents are utilized as metadata. In this talk, I will discuss three projects that are exploring ways to improve health information seeking: 1) Automated vocabulary and concept generation system, 2) An interface that employs visualization to support navigation and retrieval of health related information and 2) A machine-learning based consumer health information system that learns from interactions with its users and can support personalized delivery of health information. The talk will conclude with a discussion on privacy and security measures and a new architecture for supporting the online transmission of sensitive health information.
