语义Web的全面实现需借助于语义标注,标注网页信息会涉及到多个本体。据此,通过研究桥本体,提出一个在本体集成的基础上建立起来的多本体语义标注模型。该模型利用桥本体集成顶层本体和多个领域本体,同时借助基于本体的信息抽取技术对网页进行语义标注,并将标注信息存入标注库,使标注信息与网页分离,提高语义检索的效率。通过举例说明了本模型的合理性。
Full implementation of the semantic web requires the widespread automatic semantic annotation, it is better to annotate the current web documents with multiple ontologies. A multi-ontologies semantic annotation model based on ontology integration is put forward. This model adapts top ontologies and domain ontologies as ontology repository, and makes full use of bridge ontology to integrate different ontologies, meanwhile exploits ontology-based information extraction technology to add semantic annotation to web pages. Annotation information is stored in the annotation repository, separated from web pages to enhance the efficiency of semantic search. Examples illustrate the rationality of the model.
