Opinion Mapping: Information Visualization Approaches for Comparative Sentiment Analysis

William H. Hsu, Praveen Koduru
2012 European Workshop on Human-Computer Interaction and Information Retrieval  
In this position paper, we discuss the problem of extracting information about chronic diseases from the large volume of text written in health blogs, mailing lists, forums, and other electronic venues  ...  For example, in information portals such as HealthMap.org, which are searchable by location and disease, the data are user-reported and collaboratively maintained, but not automatically extracted from  ...  users via relational data extracted from their profiles.  ...
