[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 single resource construction ontology has the limitations of conceptual completeness and semantic integrity. In order to meet the individual needs of users for resource retrieval, combining the respective advantages of FCA and heterogeneous resources, the means of building ontologies using heterogeneous resources Overcome the limitations of a single resource. [Method / Process] Thesaurus and Folksonomy data set as the data source, each form the formal context, and through overlapping operation to obtain the formal context of heterogeneous resources, converted into a concept lattice, concept lattice from the concept model extracted using protégé Tools and OWL language to build experimental ontology. [Results / Conclusion] Three factors, word weight, word-formation rate and word-loss rate, were used to evaluate the effect of experiment ontology construction. The experimental results show that the ontology of fusion effectively enriches the relationship between concept and concept, has more advantages than the ontology of single resource construction, and provides a new feasible scheme for ontology construction.
