"DiLiA: Interactive Exploration of Digital Libraries for Information Discovery"


Abstract: DiLia (Digital Library Assistant), a browser-based interface for the exploration of digital libraries, is being developed at the German Center for Artificial Intelligence (DFKI) in Berlin. In this talk, I will discuss how understanding of visualization and interaction with the information discovery system DiLiA can be improved by exploiting the properties and principles of human spatial problem solving and navigation in real world environments. I will outline the properties that these two problem domains have in common and also highlight the differences between them. In the end, I will propose a visualization of a data space that is inspired by the discussed principles and makes use of principles of faceted search. I will also demonstrate how users can explore digital libraries through DiLiA. The aim of DiLiA's visualization is to invoke in users a sense of orientation in scientific literature that is created by intelligently presenting the underlying content.

Bio: Dr. Richter is a visiting faculty in the School of Information Sciences at Pitt. Prior to coming to Pittsburgh, he was working in the Transregional Collaborative Research Center SFB/TR 8 Spatial Cognition in Bremen for the past 6 years. In 2007, he was a visiting researcher at the Geomatics Department, University of Melbourne, Australia. Kai-Florian's work is set in the intersection between Artificial Intelligence, Cognitive Science, and Geo-Information Science. His main interests are in the intelligent communication of (spatial) information and in the implementation of cognitive principles in assistance systems. He holds a PhD in Informatics (computer science) from Bremen University, Germany.
