Analysis of Ontology Semantic Tagging Method for Semantic Web-Oriented Big Data

The transformation of formal representation based on ontology knowledge. The dimension is generated under the guidance of ontology, and the annotation result is a formal representation consistent with ontology, which ensures the consistency between dimension and ontology semantics. This paper introduces a semi-automatic text tagging tool, which can be divided into management tasks, information extraction, automatic learning and information marking. This paper proposes a semantic tagging method for big data ontology oriented to the semantic web.
