Situation Knowledge Service Model Based on Ontology Technology

摘要

To tackle problems of low coupling between knowledge organization and business process, and difficulty in balancing the efficiency and accuracy of knowledge retrieval, this paper proposes a situation knowledge service model based on ontology technology. Firstly, the situation ontology is encapsulated into business process-oriented knowledge nodes to meet operational command business requirements; then, knowledge nodes are organized into knowledge trees according to business flow by using directed acyclic graph; finally, a knowledge retrieval strategy is designed to gradually lock the target knowledge resources from two dimensions of semantic relationship and business logic. Through the performance analysis, it is found that the model in this paper can quickly and accurately retrieve the required knowledge resources in the situation knowledge sharing scenario, with high practical values.
