Gary Marchionini, Ph.D.: Human-Computer Information Retrieval: Gaps, Overloads, and Sensemaking

Watch

Gary Marchionini, Ph.D.- Human-Computer Information Retrieval aims to bring humans more fully into the retrieval process. Rather than a turn-taking approach, HCIR aims to engage humans throughout the information seeking experience by leveraging dynamic query user interfaces and agile views of the ongoing process. Web-based retrieval systems use mainly implicit user engagement at this time, however, opportunities exist for leveraging explicit user engagement in personal information (e.g., self-generated health information) or collaborative information seeking settings that accrue context over multiple sessions. This talk will focus on evaluation as the key challenge of HCIR for both development and adoption.
