A Study on a Knowledge Graph Construction Method of Safety Reports for Process Industries

There are some representative reports in industrial safety engineering, such as the Hazard and Operability Analysis Pre-Hazard Analysis; however, a large amount of knowledge report has not been fully explored. In order to reuse release value knowledge, this paper constructs new extraction framework. The framework combines asset management shell summarize concept entities machine description language model language. According template, also knowledge-mapping standard structure. Specifically, firstly, considering that structure is different processes process industry, innovatively proposes general structure, which provides practical solution for integration representation problems processes. Secondly, based on research progress named entities, presents an entity method (INERM) industry. This designs weight calculate each sentence, adds part-of-speech improve algorithm, alleviates problem existing methods cannot reasonably use semantic information context word. Finally, we construct triple rules store it Neo4j. paper, four semantic-type templates five relation constructed map standardization construction comparative experiments show accuracy INERM test set improved by 17 percentage points average compared with other key algorithms. A total 1329 directional application example fluid transportation process, number references more conducive improving guarantee transport process.
