面向网络大数据的建设项目施工领域知识融合框架研究

Research on knowledge fusion framework in project construction field based on network-oriented data

网络大数据具有多源异构、体量巨大、实时变化等特点,但在建设项目施工领域信息融合已经不能满足智慧施工的需求,需要更高层级的知识服务来满足用户的需求。针对这些特征与需求构建了网络大数据背景下的建设项目施工领域知识融合框架,该框架主要通过数据获取与知识评估、知识结构统一、融合处理、用户需求反馈与知识服务等4个模块,最终实现建设项目施工的知识服务。

The network big data has the characteristics of multi-source heterogeneity,huge volume and realtime changes etc.,while the information integration in the construction field of construction projects can no longer meet the needs of intelligent construction,a higher level of knowledge service is needed to meet the needs of customers. Based on these characteristics and needs,the knowledge integration framework of construction projects in the context of network big data are constructed. The knowledge service for project construction is finally realized through the framework by the four modules including data acquisition and knowledge assessment,knowledge structure integration,integration processing,user demand feedback and knowledge service.
