Trial Construction of an Advanced Computer-readable Lexical Database Capable of Automatic Acquisition of Lexical Information

(1)词汇库的扩展和报纸文章数据的分类：使用《Shin-Meikai Kokugo Jiten》(Sanseido出版公司)扩展了现有的词汇库。和EDR电子词典(日本电子词典研究所)，以及报纸文章数据进行了分类。(2)描述语义系统的数据结构的确定：在EDR电子词典的基础上确定了数据结构，并在计算机上对语义系统的数据进行了分类。(3)未登录词自动检测子系统的设计与实现：设计并实现了一个用于文本词法和句法分析的程序，未登录词句法语义信息自动推理子系统的设计与实现：确定了未登录词系统语义信息自动推理子系统的数据结构，设计并实现了程序。(5)实现了高级词库系统的基本部分，并对其运行进行了初步确认。(6)词库系统详细规格的确定：系统采用40M字节的主存。(7)词汇数据详细规格的确定：词条总数为：187,868个名词，645个代词，10,620个动词，1,124个形容词，1,345个副词，144个其他词。(8)高级词库系统的构建：系统使用ARY/PROLOG语言构建，目前占用142K字节的内存。(9)系统评估：使用词汇数据和来自报纸文章的电子文本对系统的性能进行了评估，结果证实了当前系统的基本有效性。

(1) Expansion of lexical data and classification of newspaper article data : Existing lexical data have been expanded using "Shin-Meikai Kokugo Jiten" (by Sanseido Publishing Co.) and EDR Electronic Dictionary (by Japan Electronic Dictionary Research Institute, Ltd.), and newspaper article data have been classified.(2) Determination of data structure for describing the semantic system : The data structure has been determined on the basis of the EDR Electronic Dictionary, and the data for the semantic system have been classified on a computer.(3) Design and implementation of the subsystem for automatic detection of unknown words : A program has been designed and implemented for the morphological and syntactic analysis of text, and for detecting unknown words.(4) Design and implementation of the subsystem for automatic inference on syntactic and semantic information of unknown words : The data structure has been determined and the program has been designed and implemented for the subsystem for automatic inference of systematic and semantic information of unknown words.(5) Implementation of the basic part of the advanced lexical database system and preliminary confirmation of its operation.(6) Determination of the detailed specifications for the lexical database system : A 40M byte main memory was adopted for the system.(7) Determination of the detailed specifications for the lexical data : The total numbern of lexical items are : 187,868 nouns, 645 pronouns, 10,620 verbs, 1,124 adjectives, 1,345 adverbs, and 144 others.(8) Construction of the advanced lexical database system : The system has been constructed using Arity/Prolog language, and currently occupies 142k bytes of memory.(9) Evaluation of the system : The performance of the system has been evaluated using the lexical data and the electronic texts from newspaper articles, and the results congirmed the basic validity of the current system.
