The main assumption is that users will be able to benefit from the interaction with the system that can understand user needs actively. The users themselves are not just passive recipient, but an active player in this picture who are eagerly willing to manipulate and control the system. They are like collaborating with the system, by letting the system learn about themselves (personalization), perceiving the problem space and the state of the system’s learning (visualization), and commanding the system to move to the appropriate direction.

Therefore, I have been working on projects that strongly focus on fortifying user ability for personalized information retrieval and access problem. The examples are open (visual) user models, user profile mediation for personalized searching, named-entity based information search/browsing, and reference point-based spatial visualization for user models. Those works were published in major journals or conferences including IPM, IVS, and WWW.

The index structure is capable of handling images as well as videos and the typical content-based retrieval strategies of each from within one general framework. I have used social network modeling to visualize the semantic relationships between multimedia data and analyzed their evolving roles when accessed by multiple users in a collaborative search environment. I am investigating to use the results of such analyses to optimize the different functionalities of the index structure. Currently, I am also in the process of embedding the proposed index structure into PostgreSQL database kernel and support range and k-NN search techniques from within the database framework.
