Abstract: Intangible cultural heritage is a valuable resource of human civilization, history and culture. The use of ontology technology can realize the digital management of intangible cultural heritage resources, which is conducive to the protection, utilization and sharing of intangible cultural heritage resources. The ontology framework based on CIDOC CRM for preservation of cultural relics is firstly used in the intangible cultural heritage of building construction techniques for Chinese traditional wooden structure architecture. CIDOC CRM is extended according to the characteristics of the architectural field to define the ontological concept classes and attributes of intangible cultural heritage knowledge in the field. In the process of instantiation, the algorithm of TextRank is used to process text corpus to expand ontology instances. Finally, the ontology model is mapped and it is stored in Neo4j diagram database to realize the visual display in the form of knowledge graph. The results show that the ontology model of traditional architectural intangible cultural heritage knowledge constructed using the above methods is practicable, which can effectively connect various fragmented knowledge. The constructed ontology can be used for knowledge management and will play an important role in the digital protection and rational utilization of intangible cultural heritage in the architectural field.

Key words: intangible cultural heritage, CIDOC conceptual reference model（CIDOC CRM）, ontology, knowledge graph, building construction techniques for Chinese traditional wooden structure architecture

摘要： 非物质文化遗产是人类文明和历史文化的宝贵资源。运用本体技术可以实现非遗资源数字化管理，有利于非遗资源的保护、利用和共享。项目首次将文物保护领域的本体框架CIDOC CRM用于中国传统木结构建筑营造技艺这一非遗领域，并结合建筑领域的特性对CIDOC CRM模型结构进行选择和扩充，定义建筑领域非遗知识本体的概念类及其属性，并在实例化过程中运用TextRank算法处理文本语料，实现本体实例的扩充，将本体模型进行数据映射，存入Neo4j图数据库中，以知识图谱的形式实现可视化展示。实验表明：运用上述方法构建传统建筑非遗知识本体模型是可行的；创建的本体能将各种碎片化知识有效地连接在一起。该方法可用于对领域知识进行管理，将在建筑领域的非遗数字化保护和合理利用方面起到重要作用。
