摘要
海洋牧场装备监测系统是海洋牧场装备体系的重要组成部分,也是海洋牧场正常运转和设备安全性的保障系统。为增强海洋牧场管理人员及一线操作员工对装备监测系统的全面了解和提高设备维护水平,突破因为相关信息碎片化、知识体系不健全而形成的监管肓目性,构建了监测系统知识图谱。采用自上而下和自下而上相结合的方法,围绕监测系统一级设备、二级设备、二级设备功能、二级设备工作原理和二级设备使用要求5个方面,获取全面信息,建立知识关联,解决海洋牧场装备监测系统知识碎片化问题。研究中,自上而下构建模式层,通过本体建模完成知识图谱的框架;自下而上构建数据层,实现数据获取与知识抽取、知识表示及知识融合,并将图谱数据储存于Neo4j数据库。构建的知识图谱为后续设计和开发海洋牧场装备智能问答系统、智能搜索系统、故障诊断系统及智能推荐系统提供了参考依据和深度开发的基础。
Marine ranching equipment monitoring system is an important part of marine ranching equipment system,and also a guaran-tee system for normal operation and equipment safety of marine ranching.In order to enhance comprehensive understanding of equip-ment monitoring system for marine ranching managers and front-line operators and improve level of equipment maintenance,break through blind supervision caused by fragmentation of relevant information and imperfect knowledge system,knowledge graph of monit-oring system was constructed.Top-down and bottom-up methods were adopted to obtain comprehensive information from five aspects,namely primary equipment,secondary equipment,secondary equipment function,secondary equipment working principle and applica-tion requirements of secondary equipment in monitoring system,so as to establish knowledge correlation and solve problem of know-ledge fragmentation in monitoring system of marine ranching equipment.In the research,model layer was constructed from top to bot-tom,and framework of knowledge graph was completed through ontology modeling.Data layer was constructed from bottom up to real-ize data acquisition,knowledge extraction,knowledge representation and knowledge fusion,and atlas data was stored in the Neo4j database.Knowledge graph constructed provided a reference basis for subsequent design and development of intelligent question and an-swer system,intelligent search system,fault diagnosis system and intelligent recommendation system for marine ranching equipment.
