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

本研究将语言习得和概念形成作为交际行为的基础，作为语言能力与运动、认知、理解、推理等其他能力之间的相互作用进行了调查。基于调查和语言学、心理学和信息科学的数据，从四个子领域对每个过程的建模进行了研究。知识习得、言语习得、词语和概念习得、话语和对话能力习得。综合分析了四种过程模型在知识和相关科学领域的应用。每个子领域的主题如下。2.知识获取：人与机器的知识获取、第一语言学习、隐藏含义的理解、日常科学的本质、约束满足和特征结构的综合。2 .语言习得：口语理解中的概念形成，从婴幼儿到成人语言感知能力的发展，利用视觉和听觉信息的语言习得。3 .词汇与概念习得：婴儿概念结构的发展，大规模语言数据库的排列，分层概念的形成，概念变化的机制，日语文本分析中未知词的习得。话语与对话能力的习得：智能辅导系统中的人类问题解决，基本概率问题中的误解自动分析。集成模型及其应用：电子词典、机器翻译、计算机辅助教学等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.
