[目的/意义]单一资源构建本体存在概念完整性和语义关系完整性的局限,为了满足用户对资源检索的个性化需求,综合FCA和异构资源各自的优势,采用异构资源构建本体的手段克服单一资源的局限。[方法/过程]以主题词表和Folksonomy数据集为数据源,各自构建形式背景,通过并叠置运算获得异构资源的形式背景,转换成概念格,从概念格中抽取概念模型,使用protégé工具和OWL语言构建实验本体。[结果/结论]通过词重率、增词率、漏词率3个参数,评估实验本体构建效果。实验结果表明,融合的本体有效地丰富了概念和概念间关系,比单一资源构建的本体更具有优势,为本体构建提供了一种新的可行方案。

[Purpose/significance] The ontology built by a single resource has a limitation on conceptual integrity and semantic relation of integrity. This paper aims to resolve this problem, as well as meet the personalized needs of users on the resource retrieval. It is an available alternative to synthesize advantages of FCA and heterogeneous resources, and utilize heterogeneous resources ontology construction. [Method/process] Specifically, as data sources, the paper develops formal contexts of thesaurus and folksonomy respectively, and obtains the formal contexts of heterogeneous resources by apposition-overlap operation. Afterwards, it is necessary to transform these formal contexts to concept lattices, and extract a conceptual model. Then, protégé tool and OWL language are applied to construct an experimental ontology. [Result/conclusion] Finally, Lexical Overlap, Ontology Improvement, Ontology Loss were adopted to evaluate the effect of this experimental ontology. The results suggest that the fusion ontology, which can enrich concepts and their relations more effectively, has more advantages than the ontology built by a single resource. Furthermore, it provides a new feasible scheme for ontology construction.
