OntCheck : An Ontology-Driven Static Correctness Checking Tool for Component-Based Models

Abstract EN

Component-based models are widely used for embedded systems.

The models consist of components with input and output ports linked to each other.

However, mismatched links or assumptions among components may cause many failures, especially for large scale models.

Binding semantic knowledge into models can enable domain-specific checking and help expose modeling errors in the early stage.

Ontology is known as the formalization of semantic knowledge.

In this paper we propose an ontology-driven tool for static correctness checking of domain-specific errors.

two kinds of important static checking, semantic type and domain-restrcted rules, are fulfilled in a unified framework.

We first propose a formal way to precisely describe the checking requirements by ontology and then separately check them by a lattice-based constraint solver and a description logic reasoner.

Compared with other static checking methods, the ontology-based method we proposed is model-externally configurable and thus flexible and adaptable to the changes of requirements.

The case study demonstrates the effectiveness of our method.
