The notion of ontology modularization refers to a methodological principle in ontology engineering

Ontology engineering

Ontology engineering in computer science and information science is a new field, which studies the methods and methodologies for building ontologies: formal representations of a set of concepts within a domain and the relationships between those concepts....

. The idea is that an ontology is built in a modular manner, i.e. developed as a set of small modules and later composed to form, and be used as, one modular ontology.

One of the major research meetings on ontology modularization is the International Workshop on Modular Ontologies series.
