Making sense of a healthcare forum - Smart keyword and user navigation graphs

More consumers are using social media to keep abreast of personal health and well-being issues. In addition to web portals (e.g., WebMD.com and MedicineNet.com), which serve as repositories of expert derived health information (Baker et al. 2003; Sillence et al. 2007), consumers are turning in large numbers to medical forums (e.g., DiabetesForum.com and DiabetesDaily.com for diabetes management, IBSGroup.org for IBS, etc.), where communities of people with shared medical issues exchange knowledge and experiences with their illnesses (Tustin 2010). On a large forum with several hundred thousand posts, it is very hard for users to find the most relevant posts just by using the search functions of the forum. Hence, there is a need for smarter visual navigation interfaces that can organize the relevant information more systematically and provide better pathways for accessing content.
