为了解决以自然语言表示节点标签的分类树很难通过自动软件agents来进行自动推理的问题,通过词性标志、词义辨析、连接词辨析和受约束的自然语言定义及转换等步骤,将分类树中每一个节点对应的自然语言标签转换成了机器能够识别的逻辑表达式,从而使整个分类树转换成了一个轻量级本体,它适合应用在数据整合的语义匹配、文档分类和语义搜索等方面的自动推理,从而促进了本体知识的自动化推理,为以后文本自动检索奠定基础.
為瞭解決以自然語言錶示節點標籤的分類樹很難通過自動軟件agents來進行自動推理的問題,通過詞性標誌、詞義辨析、連接詞辨析和受約束的自然語言定義及轉換等步驟,將分類樹中每一箇節點對應的自然語言標籤轉換成瞭機器能夠識彆的邏輯錶達式,從而使整箇分類樹轉換成瞭一箇輕量級本體,它適閤應用在數據整閤的語義匹配、文檔分類和語義搜索等方麵的自動推理,從而促進瞭本體知識的自動化推理,為以後文本自動檢索奠定基礎.

In order to solve the problem that classifications were very hard to be reasoned about by automated software agents and represent annotations of little use for semantic Web applications since their labels or nodes were written in natural language, this paper introduced an approach to transform a hierarchical directory into lightweight ontology by a series of steps, including part-of-speech tagging, word sense disambiguation, coordination disambiguation, and new controlled natural language definition and conversion, which then helped formalize the natural language labels into simple description logic formulae and provided the significant basis for further ontology reasoning and document retrieval.
