Data extracted from this database has been used in a number of relational learning papers. The version available here was downloaded from the IMDb website, converted into SQL using the prodecure described in http://imdbpy.sourceforge.net/docs/README.sqldb.txt and finally a subset of the tuples was converted into a Prolog file.

This data set contains 4,337 molecules labeled according to mutagenicity (2,401 mutagens and 1,936 nonmutagens). Originally developed by Kazius et al (2005) it has been used in a number of machine learning papers, especially those studying graph kernels.
Biodegradability   Download
This is an older data set of chemical structures containing 328 compounds labeled by their half-life for aerobic aqueous biodegradation (a regression task).
