摘　　要：【目的/意义】本体论在信息共享和知识管理中的广泛应用,需要更加高效、多源的本体开发方法。本体进化从各种形式的数据中自动或半自动地发现本体知识,可以解决本体开发中本体知识获取的瓶颈问题。传统的本体进化方法大多数基于非结构化的文本资源,需要较为繁琐和复杂的自然语言处理过程,本文提出基于纳米出版物的领域本体进化模型实现领域本体的进化。【方法/过程】在识别纳米出版物特点的基础上,通过纳米出版物开源平台Nanopub Monitor获取领域相关纳米出版物,并利用语言学和机器学习的方法抽取出领域本体要素,进而与初始本体要素匹配实现本体的进化,形成“实体抽取-元素匹配-本体变更”三环节的本体进化模型。【结果/结论】本文以农业机械领域为例,在初始本体的基础上利用本体进化模型实现了领域本体的进化,构建了农业机械领域本体,提升了领域本体进化的效率。【创新/局限】领域本体的进化受限于该领域纳米出版物的数量。[Purpose/significance]The wide application of ontology in information sharing and knowledge management requires a more efficient and multi-source ontology development method.Ontology evolution can discover ontology knowledge automatically or semiautomatically from various forms of data,which can overcome the bottleneck of acquiring ontology knowledge in ontology development.Most of the traditional ontology evolution methods are based on unstructured text resources,which require cumbersome and complex natural language processing.In this paper,a domain ontology evolution model based on Nanopublication is proposed to realize domain ontology evolution.[Method/process]On the basis of recognizing the characteristics of Nanopublication,the domain-related Nanopublications are acquired through the Nanopub Monitor,and the domain ontology elements are extracted using linguistics and machine learning methods,and then matched with the initial ontology elements to realize the evolution of ontology.The ontology evolution model of"data acquisition-element matching-ontology change"is formed.[Result/conclusion]In this paper,the agricultural machinery domain is taken as an example.Based on the initial ontology,the ontology evolution model is used to realize the evolution of the domain ontology,and the agricultural machinery domain ontology is constructed to improve the efficiency of domain ontology evolution.[Innovation/limitation]The evolution of domain ontology is limited by the number of nanopublications in the domain.
