Towards an Effective Extension of Activity Streams

Activity Streams is a data format designed to describe activities. Although its specification is written in natural language, its core vocabulary is formally defined in an OWL (Web Ontology Language) ontology. In this work, we propose a set of additional OWL axioms to extend the existing ontology, with the goal of enabling more detailed, precise, and machine-interpretable descriptions of Activity Streams. This enhancement aims to support real-world applications, such as those related to automatic test generation from OWL specifications.
