Inductive Logic Programming for Structure-Activity Relationship Studies

Nowadays, vast amounts of chemical compound structure can be produced due to the advance in High Throughput Screening technology that automates compound screening using the combination of robotics, image processing and pattern recognition. From these data, knowledge describing compound activities and characteristics from their structures is essential since it can be used for predicting characteristics of unknown compounds for developing new drugs. Machine learning and data mining techniques have been applied in order to automatically obtain models describing the relations between structure and activity. However, traditional data mining algorithms have limitations on knowledge representation. Thus, complicated structures of chemical compounds cannot be handled efficiently.

Extended from traditional machine learning techniques,Inductive Logic

Programming (ILP) applies first-order logic for representing data. This allows complicated structures or relations among training examples to be denoted without losing any information. Moreover, learning results in form of first-order rules are comprehensible. Knowledge obtained can be easily explained to domain experts.
