The Internet has become one of the most important sources for consumers to seek health-related information. Over 80% of Internet users in the U.S. have looked online for health information such as a specific disease or treatment, and 60% said the information found online affected their decision making of taking care of themselves and others. Although substantial amount of health information is available online, it is not necessarily easy for general consumers to effectively retrieve such information. Major challenges in health information retrieval include information overload and ineffective interface and organization.
In this talk, I will focus on three aspects for enhancing the retrieval of consumer health information: effective methods to organize consumer health information, efficient information retrieval interface to query and explore consumer health information and avoid information overload, and comparative evaluation of consumer health information retrieval interfaces to show their efficacies. First, I will introduce a non-profit consumer health information website NetWellness (http://netwellness.org/), providing high-quality community question answer services. Next, I will present a new multi-topic assignment method based on Formal Concept Analysis (FCA) and semantic annotation to organize health questions by health topics in NetWellness. Third, I will introduce a novel Conjunctive Exploratory Navigation Interface (CENI), developed for exploring NetWellness health questions with health topics as dynamic and searchable menus, complementing keyword-based search. To show the effectiveness of CENI, I will present a comparative search-interface evaluation using crowdsourcing through Amazon Mechanical Turk (AMT), a new and valuable method to collect user evaluation data.

Licong Cui is a PhD candidate in Computing and Information Science here at Case Western Reserve University under the mentorship of Dr. GQ Zhang, expected to graduate in August 2014. She received her MS degree in Pure Mathematics and BS degree in Information and Computing Science from Shaanxi Normal University, Xi'an, China. Her research interests include information retrieval, text mining, data integration and management, and theoretical computer science. She has combined her computer science theory knowledge with software design and development skills to make key contributions to several NIH-funded projects. Her work has been published in leading biomedical informatics journals and conferences, including Journal of Medical Internet Research (JMIR), Journal of American Medical Informatics Association (JAMIA), Journal of Biomedical Informatics (JBI), IEEE International Conference on Healthcare Informatics (ICHI), and American Medical Informatics Association (AMIA) Annual Symposium.
