An Integrated Discovery System

چکیده
Previous discovery systems have successfully rediscovered known scientific laws . However, they have addressed only limited parts of the empirical discovery task . In this paper we introduce an integrated discovery system (IDS) which addresses many issues of empirical discovery. IDS operates in three stages : taxonomy formation, qualitative discovery, and quantitative discovery. We focus on the latter two stages introducing qualitative schemas as a means for representing qualitative discovery and showing how they can be learned by observation . IDS uses qualitative schemas to find quantitative laws . The implemented system has discovered intrinsic properties, such as the melting point of substances, and numeric laws, such as the conservation of mass of an object going through a phase change.
