On Friday, September 19th, Dr. Gary Marchionini will be presenting as part of the School of Informatics and Computing’s Colloquia Series.
The topic is: Human-Computer Information Retrieval: Gaps, Overloads, and Sensemaking.
This event will be held on IUPUI’s campus in IT 152 at 10:00am.
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. Evaluation must take into account human variables as well as the sophistication of today’s search systems that shift the human requirements from query specification to filtering and making sense of large volumes of increasingly rich search results.
