In this paper, we describe the structure and outline the content of the tutorial on Agent-Based Ontology Alignment. The tutorial is planned in two parts with an overall timeframe of 2 hours. Part 1 covers the basics of ontology alignment -- basic definitions; problem statements and problem classification based on the settings; the applications of ontology alignment and the requirements to ontology alignment solutions. Part 2 is more advanced in a sense that it overviews and analyses agent-based frameworks for ontology alignment and offers a demonstration of an agent-based system that solves one of the problems of ontology alignment. The tutorial offers a walkthrough problem in ontology alignment -- ontology instance migration, which receives a more in-depth treatment throughout the tutorial. A walkthrough example of the two very simple Biblio ontologies is also used to make the narration consistent.
