Information Seeking, Interactive Information Retrieval (IIR), Information Fostering

To better understand people’s information seeking processes and to provide personalization and recommendations to them as methods for helping the information seekers, I have been involved in several research activities that investigate elements of interactive information retrieval (IIR), specifically focusing on detecting topic, task, and intentions.

Collaborative Information Seeking (CIS)

Collaborative information seeking (CIS) involves a coordinated effort to better understand and solve a shared problem of interest, such as siblings searching together for information about an elderly parent’s medical condition. My research on CIS has been primarily concerned with investigating how and why people work in collaboration in information-intensive tasks, and what support can be provided to facilitate and encourage such collaborative behavior.

Social Information Seeking (SIS)

Social information seeking (SIS) refers to queries or questions that people pose to their peers or a community to obtain their thoughts, opinions, and validations, e.g., asking for travel advice on online community-based question-answering services such as Yahoo Answers or Quora. My research on SIS has relied primarily on studying community-based question-answering (Q&A) services such as Yahoo! Answers, and social media services such as Twitter.

Social Media

I have been looking at various aspects of social media to address research questions relating information seeking and sharing through social/community channels such as YouTube, Twitter, and Facebook. Much of my work in this area has been interdisciplinary in nature, in that I have been collaborating with researchers from various fields such as political science, media studies, journalism, archiving and preservation, and information and computer sciences.
