Abstract: This paper presents PASER, a system for automatically synthesising curricula using AI Planning and Machine Learning techniques based on an ontology of educational resources metadata. Given the initial state of the problem (learner|s profile, preferences, needs and abilities), the available actions (study an educational resource, take an exam, join an e-learning course, etc.) and the goals (obtain a certificate, learn a subject, acquire a skill, etc.), the planning module of PASER constructs a complete educational curriculum that achieves the goals. The Machine Learning module of PASER matches textually described learning requests, objectives and prerequisites to concepts of the ontology.

Keywords: curricula synthesis; automated planning; text mining; problem solving; machine learning; ontology; educational resources metadata; educational curriculum; teaching; education; artificial intelligence; curriculum planning.
