OntoKin

OntoKin models chemical kinetic reaction mechanisms using the Web Ontology Language (OWL) to provide formal semantic representation, enable semantic querying, and support validation of reaction mechanisms.

Key Features:

• Semantic modeling: Represents chemical kinetic reaction mechanisms using the Web Ontology Language (OWL) for formal, machine-readable semantics.
• Automation: Automates the assertion process within the ontology development framework.
• Expert validation: Incorporates domain expert assessment and validation using reasoning tools to ensure ontology reliability.
• Knowledge base integration: Integrates the ontology and its instantiations into a knowledge base (KB) and deploys the KB using the RDF4J triple store.

Scientific Applications:

• Querying mechanisms: Enables querying across different chemical kinetic mechanisms to identify variations such as changes in the rate of NOx formation during ammonia combustion.
• Modeling atmospheric pollution: Supports modeling efforts related to atmospheric pollution dispersion and environmental impact assessment.
• Simulation of pollutant emissions: Facilitates semantic representation and comparison of mechanisms underlying pollutant emissions from internal combustion engines.

Methodology:

Models mechanisms in OWL; automates assertion generation; validates the ontology via reasoning tools and expert assessment; integrates ontology and instantiations into a KB deployed with the RDF4J triple store.
