摘　　要：[目的 /意义]随着大数据的迅速发展,面向标准领域的知识服务已经成为当前大数据背景下标准信息化发展的前沿热点问题,基于知识图谱技术开展标准文献资源服务,对于揭示标准知识的整体关联性,让标准数据发挥更大的效用,具有重要的研究意义。[方法 /过程]本文在解析标准文献特征及内容知识结构的基础上,提出了用于描述标准知识的标准知识单元五元组,建立了面向标准文献的资源层—描述层—映射层的三层知识图谱构建模型。进一步提出了基于规则和基于LDA主题模型的标准文献知识图谱构建的集成式方法。[结果 /结论 ]通过建立起标准文献的知识图谱,有助于扩展实体关系类型,并以期为后续实证研究提供理论和方法支撑。[Purpose/Significance] With the rapid development of big data, knowledge service in the field of standards has become a frontier hot issue in the development of standard informatization. Carrying out standard literature resource service based on knowledge atlas technology has important research significance for revealing the overall relevance of standard knowledge and making standard data more effective. [Method/Process] On the basis of analyzing the characteristics and knowledge structure of standard documents, this paper puts forward the five tuples of standard knowledge units for describing standard knowledge.A three-layer knowledge map construction model of resource layer description-layer mapping-layer for standard documents is proposed. Further, an integrated method for the construction of standard literature knowledge map based on rules and LDA topic model is proposed.[Results/Conclusions]Through the construction knowledge map of standard literature, can help to extend entity relationship types,andthat will provide theoretical and methodological support for subsequent empirical research.
