Research and exploration on network public sentiment monitoring for financial securities based on ontology

According to the application research in the information system and the rules of construction on domain ontology, this paper proposed the conception of adding the financial domain ontology to the existing public sentiment monitoring system for financial securities and built the system architecture based on ontology to resolve the problems such as the integration of heterogeneous data, domain information sharing, the communication among netizens by using different terminology, the intelligence of providing public sentiment and the phenomenon of noise, which laid the foundation of realizing the artificial intelligence technology. With the help of the existing system, the paper focused on introducing the construction and formation of domain ontology and describing the integration between domain ontology and system, based on which a semantic system would be formed and the final result would be predicted.
