Key Technologies of Building Knowledge Base Based on Oracle Database

Knowledge bases are important collections of knowledge that store, organize, and process knowledge, as well as provide knowledge services. Knowledge bases are an important part of building an open infrastructure that collects and preserves large amounts of research content and provides access to it. The study investigates the key technologies for building the Japanese sentence pattern knowledge base based on Oracle database. First, the storage structure of Oracle database is studied; then, the knowledge acquisition based on web crawler technology is studied; then, the requirement analysis is conducted based on the use case diagram technology; finally, the conceptual structure design and logical structure design of the knowledge base storage structure are conducted. The research results of this paper, which conform to the basic specifications of software engineering, provide a complete solution for the construction of Japanese sentence patterns knowledge base and lay the foundation for software development and implementation.
