摘要:

本体构成了各种计算机科学学科的基本兴趣,如语义网,信息检索,数据库设计等,它们旨在提供一个正式的,明确的和共享的概念化和不同社区之间的共同领域的理解。此外,它们允许明确定义特定领域的概念及其约束。然而,本体开发的分布式特性和本体工程师观点的差异导致了本体之间的“语义异构性”。语义异构性是实现本体间互操作性的主要障碍。为了克服这一障碍,我们提出了一个多用途的框架,利用WordNet通用知识库:i)发现和纠正不正确的语义关系的概念之间的本体在一个特定的领域。该步骤是本体合并的一个基本步骤。ii)通过计算概念之间的语义关系来合并特定领域的本体。㈢通过在网上获取统计资料,处理WordNet中缺少概念的问题。4.用这些缺失的概念丰富WordNet。一个实验性的框架实例和比较国家的最先进的语法和语义为基础的系统验证我们的建议。

英文摘要:

Ontologies form the basic interest in various computer science disciplines such as semantic web, information retrieval, database design, etc. They aim at providing a formal, explicit and shared conceptualization and understanding of common domains between different communities. In addition, they allow for concepts and their constraints of a specific domain to be explicitly defined. However, the distributed nature of ontology development and the differences in viewpoints of the ontology engineers have resulted in the so called "semantic heterogeneity" between ontologies. Semantic heterogeneity constitutes the major obstacle against achieving interoperability between ontologies. To overcome this obstacle, we present a multi-purpose framework which exploits the WordNet generic knowledge base for: i) Discovering and correcting the incorrect semantic relations between the concepts of the ontology in a specific domain. This step is a primary step of ontology merging. ii) Merging domain-specific ontologies through computing semantic relations between their concepts. iii) Handling the issue of missing concepts in WordNet through the acquisition of statistical information on the Web. And iv) Enriching WordNet with these missing concepts. An experimental instantiation of the framework and comparisons with state-of-the-art syntactic and semantic-based systems validate our proposal.
