Current Projects

Body Listening Project

The Body Listening Project is a collaborative effort to create a public repository of people’s experiences of body listening and body awareness.  Being in tune with and and being able to read one’s body can be invaluable in management of one’s health.  The repository will be used to develop patient education programs, knowledge resources on body listening, and a novel system featuring innovative visual interfaces for browsing and exploring content.  Read more…

Mining Online Communities

This project focuses on the study of online health-related communities. The focus is on understanding the types of knowledge that the communities possess and the ways in which community members utilize the communities and interact with each other. Much of this research involves developing new methods for mining and visualizing of this content, and incorporates sentiment analysis, cluster analysis and topic modeling. Some of the major themes explored in the work include emotional expression, social support, interpersonal interactions and medication use. Read more…

Motivations, Contexts and Effects of Tobacco Use

In recent years, we have seen increased use of electronic cigarettes and hookah, and there is currently a need to understand more about the use experience of these tobacco products. This project focuses on investigating the motivations, contexts and effects of tobacco use. This work is in collaboration with the University of Utah and the University of California, San Diego. Read more…

Information Behaviors in the Context of Chronic Illness

This project has employed multiple methods to study the role of information in long-term health management.  Survey and interview data demonstrated that, over the course of illness, patients may initiate and/or experience differences in many aspects of their health management, including patient-provider interaction, information seeking behaviors, treatment choices and lifestyle changes. Read more…

Completed Projects

Named Entity Recognition of Slave Narratives

This project employed named entity recognition software, namely, the Stanford Core NLP Tools, to extract names from the slave narratives. The results of these extractions were verified through manual curation to verify their accuracy, and to provide additional descriptive information that could not be derived automatically. The curated knowledge was then made available through an extended version of a text exploration interface, VizText. Read more…

Results Space (NSF IIS # 0812363)

At the University of North Carolina at Chapel Hill, I served as the lead on a development project to develop the ResultsSpace Collaborative Search Environment, a tool that was used to support asynchronous collaborative information retrieval among a small group of collaborators. It is designed to promote awareness of collaborators’ searches and the documents they have rated. The system was used to examine the effects of awareness mechanisms on different aspects of collaborative information retrieval.

People, Places and Emotions

The term, “comfort women,” has been used to refer to women who were forced into a system of sexual slavery for the Japanese military from 1932 to the end of World War II. This project was undertaken to develop text mining and visualization techniques to facilitate exploration of the oral testimonies of Korean comfort women that have been translated into English. The title, “People, Places and Emotions,” is meant to encapsulate the concept that people, places and emotions are critical aspects of the women’s subjective experiences, and that pulling those elements together in a visual representation can enable website viewers to see connections that might not otherwise be apparent. The project also involved geospatial mapping of the locations that women mentioned in their testimonies, a useful feature to have because of the inherent difficulty of tracing their routes due to the circumstance of their experience.
