ABSTRACT
In this study, we examined what sources laypeople would select (i.e., visit and adopt) to resolve their health-related information needs, and how different health conditions affect the selection. Twenty-four college students participated in this user study, where they were asked to search for two separate health issues respectively: multiple sclerosis and weight loss. The search logs were collected and analyzed afterwards. We classify the online information sources on both website level and webpage level, and a webpage classification scheme based on genre is proposed. Results suggest that users» selection of sources depends on different types of health issues in terms of urgency and complexity. Health-specific webpage is a popular source and highly adopted for both tasks, but it is particularly helpful for urgent and complex health conditions. Search engines could facilitate users to navigate among scattered health information and support concerns regarding common health issues.
