Ontology-driven semantic processing architecture
OntoCast's core competitiveness lies in its ontology management system, which realizes three innovations: 1) automatic generation of domain ontology, dynamically constructing OWL files by analyzing entity relationships in documents; 2) intelligent validation mechanism, checking the reasonableness of conceptual hierarchies with the built-in reasoning engine; and 3) continuous optimization, adjusting the attribute constraints according to the feedback from users. For example, when dealing with legal contracts, the system can automatically identify the contractual relationship of "Party A/Party B" and form the LegalContract ontology. Compared with the extraction tool that only relies on NLP, this ontology-first approach improves the F1 value by 37%.
