本体作为语义网的基础是共享概念模型的明确的形式化规范说明,用于表达数据源的语义、识别和建立概念间的语义关联等。有效地构建本体成为本体应用的关键问题,本文采用形式概念分析构造本体,并利用多值背景的转换算法对词语-文档的二元关系表进行转换导出单值背景,从而更大程度上保留关系表带有的信息。
Ontology as the foundation of the semantic web is a clear formal specification of shared conceptual models for expressing the semantics of data sources, identifying and establishing semantic associations among concepts. In order to effectively construct ontology as the key problem of ontology application, this paper uses formal concept analysis to construct ontology and uses the conversion algorithm of multi-valued background to convert the binary-relational table of word-document to derive the single-valued background to preserve the relationship to a greater extent Information that the watch has.
