Co-operative Research on Modeling of Language Acquisition and Concept Formation Process in Engineering

本研究从语言能力与其他能力如运动能力、认知能力、理解能力、推理能力等相互作用的角度，对交际行为的基础--语言习得和概念形成进行了研究。例如，知识习得、言语习得、词汇和概念习得、语篇和对话能力习得。本文对四个过程模型进行了综合分析，并将其应用于知识和相关科学领域，每个领域的主题如下.知识获取：人类和机器的知识获取，第一语言学习，理解隐含意义，日常科学的本质，约束满足和特征结构的合成.语音采集：口语理解中的概念形成，婴幼儿到成人言语感知能力的发展，利用视觉和听觉信息的语言习得.词汇和概念的获取：幼儿概念结构的发展，大规模语言数据库的整理，概念形成的层次性，概念变化的机制，用于日语文本分析的未登录词的习得.话语与对话能力的获得：智能教学系统中的人类问题解决，基本概率问题中错误概念的自动分析.集成模型及其应用：用于电子词典、机器翻译、计算机辅助教学等的语言和知识处理系统。

In the research, investigation was made in the field of language acquisition and concept formation, which is a foundation of communication behavior, as interactions among language competence and other ones of motor, cognition, comprehension, inference, etc.Based on the investigation and data from linguistics, psychology as well as information science, research on modeling of each process was done in four subfields, i. e ., knowledge acquisition, speech acquisition, word and concept acquisition, and acquisition of discourse and dialogue competence. An integrative analysis was done on the models of four processes for applications in the fields of knowledge and related sciences.Themes in each subfield are as follows.1. Knowledge acquisition : knowledge acquisition by humans and machine, learning in the first language acquisition, understanding hidden meanings, nature of everyday science, constraint safisfaction and synthesis of feature structure.2. Speech acquisition : concept formulation in spoken language understanding, development of ability of speech perception from infants and young children to adults, language acquisition using visual and auditory information.3. Word and concept acquisition : development of concept structure in infants, arrangement of large-scale linguistic data base, hierarchical concept formation, mechanisms of conceptual change, acquisition of unknown words for analysis of Japanese text.4. Acquisition of discourse and dialogue competence : human problem solving in intelligent tutoring system, automatic analysis of misconception in basic probability problems.5. Integrated model and its applications : language and knowledge processing system for electronic dictionary, machine translation, computer assisted instruction, etc.
