Less-Conscious Information Retrieval Techniques for Location Based Services

Prof. Kazutoshi Sumiya & Maho Nishizawa

Dept of Applied Informatics,

Kwansei Gakuin University, JAPAN

Abstract:

We have developed methods which can deal with the users' interaction without conventional conscious searching. When a user generally performs map operations with information retrieval intentions (less-conscious), a system using our method can detect the specific operation sequences.


For example, if the user performs zooming-in and centering operations, the user is narrowing down the search area to a certain location. We define such operation sequences as chunks.
The system detects the chunks and uses them to analyse the user's operations and thereby detect the user's intentions. We have developed several prototype systems based on the proposed methods.

Bio:

Kazutoshi Sumiya received his BE and ME degrees in instrumentation engineering from Kobe University in 1986 and 1988, respectively. Then he joined Panasonic (Matsushita Electric Industrial Co). He received his Ph.D in Information media from Kobe University in 1998. He left the company and became a lecturer at Kobe University in 1999, and then was promoted to an associate professor in 2000.He became an associate professor in 2001 at Kyoto University, a professor at the University of Hyogo in 2004 and a professor at Kwansei Gakuin University in 2015.

He developed information dissemination systems and fusion technique for broadcast media and network media and he is now developing next-generation information techniques.
He was a chair of Database System special interest group (DBS) in the Information Processing Society of Japan (IPSJ) and a co-editor of IPSJ Transaction on Database and a director of IPSJ.

Refreshments will be served before the talk.
