It is tailored for biochemical databases, where the examples are 2-D descriptions of chemical compounds. The method generates all frequent fragments (i.e., linearly connected atoms) up to a user-specified length. A preliminary experiment in the domain of carcinogenicity predictions showed that bottom-up propositionalization is a promising approach to feature construction from relational data.application/pdfenThis is an author’s accepted version of a conference paper published in Proc 10th International Conference on Inductive Logic Programming: Work-in-Progress Reports. © 2022 The Authors.Conference Contribution
