This project is concerned with the development of a large-scale multi-type reasoning system, called INLEN, for extracting knowledge from databases. The system assists a user in discovering general patterns or trends, meaningful relationships, conceptual or numerical regularities or anomalies in large databases. The volume of information in a database is often too vast for a data analyst to be able to detect such patterns or regularities. INLEN integrates symbolic learning and statistical techniques with database and knowledge base technologies. It provides a user with "knowledge generation operators" (KGOs) for discovering rules characterizing sets of data, generating meaningful conceptual classifications, detecting similarities and formulating explanations for the rules, generating rules and equations characterizing data, selecting and/or generating new relevant variables or representative examples, and testing the discovered rules on new data.

A screen in which the user may examine or modify the data set to be learned from. In this dataset each example describes a separate country. The Key field provides the country name (which is not learned from), and the values for the other attributes are presented in spreadsheet form

A screen displaying rules learned from an example set. In this example the rules are displayed which describe the conditions under which eye injuries have occurred on a construction site. The numbers of examples supporting each part of the rules are measured in the columns on the right.

An example screen from the INLEN Advisory Module, in which a user may be assisted in making a decision or can speculate on unknown data. The current question for the user is displayed in the middle of the screen, and INLEN's current best hypotheses are displayed in the top right.
