Semantic Classification System based on a Contemporary Japanese Noun Thesaurus

在编写《当代日语名词词库》的同时，对词汇的语义分类进行了研究。这个同义词典现在存储在个人计算机中，并且可以使用原检索系统为同义词典轻松灵活地检索。同义词典的描述是基于同义词和上下同义词的关系。部分-整体描述在同义词典中没有完全描述。大约有6万个词条词被正确地定位在语义关系网络上。通过该词库，构建了现代日语名词的语义分类。然而，将语义相似的词分组可以让我们注意到矛盾，即不一致的现象。因此，我挑选了几组单词，并检查它们是否可以包含在同一组中。这个过程本身就是一项研究。这些考虑的结果被用来在一台个人计算机中修改同义词典的描述。同义词典的出版现在沿着这些程序准备。同义词典使我们能够研究上下词的关系。结论是，上下位词反映了一种“文化”（一种母语使用者共有的观点）。

I carried out a research of semantic classification of vocabulary, while compiling Contemporary Japanese Noun Thesaurus.This thesaurus is now stored in a personal computer and can be retrieved easily and flexibly using original retrieval system for the thesaurus.The description of the thesaurus is based on the relationships of synonym and super-ordinate-hyponym. Part-whole description is not entirely described in the thesaurus.About 60,000 entry words are properly located on the network of semantic relations. Through this thesaurus, semantic classification of contemporary Japanese nouns has been constructed. However, grouping of semantically similar words allows us to notice contradiction, the phenomenon of inconsistency. Therefore, I picked up some groups of words and checked them whether they can be included the same group or not. This process is a research by itself.The result of these considerations was used to revise the description of the thesaurus in a personal computer.The publication of the thesaurus is now prepared along these procedures.The thesaurus enables us to investigate superordinate-hyponym relationship. The conclusion is that superordinate-hyponym reflects a 'culture' (a viewpoint shared by the native speakers of a language).
