Description

Knowledge acquisition and representation in closed-loop scientific discovery systems

To cope with the wealth of scientific data, artificial intelligence scientists have begun to apply machine lea¬rning techniques in various scientific domains. Typically, these discovery systems are designed as open programs that produce human-comprehensible laws from the data humans have fed into them. However, such heavily human-dependent programs are less suited for genuine discovery work. Therefore, "closed-loop" discovery sys¬tems have been proposed, which not only generate and select hypotheses but also carry out the necessary experi¬ments. Drawing on insights from my previous work on knowledge representation and knowledge acquisition in web agents, this highly interdisciplinary project focuses on the implementation of closed-loop systems, how they acquire, represent, and communicate knowledge gained from experiments, and the cognitive and epistemological consequences of using such artifacts.

Cognitive software agents for discovery and search on the World Wide Web

The project focuses on the problem of effective and intelligent access to knowledge on the WWW. It proposes the design, implementation, and application of software agents on the web that cope with information overload in an expectation-driven way. Going beyond information retrieval services, the primary goal of the agents is to systematically discover meta-information of the web: general structural and statistical features of web pages and information dynamics of links that are hidden from human web users and designers. This web topology can be used to construct active recommendation systems (Lieberman 1997) and also to help to improve and automatize the design process of large web sites (Perkowitz & Etzioni 1998).
