ABSTRACT This proposal from the University of Pennsylvania requests funds to establish a Science Technology Center for Research in Cognitive Science. The Director of the Center will be Professor Aravind K. Joshi. The Center for Research in Cognitive Science unites a diverse and richly interconnected group from many traditional disciplines (computer science, linguistics, mathematics, philosophy, and psychology). The goal of the research is to understand the processes and mechanisms by which human beings acquire knowledge about their environment, store and retrieve that knowledge, communicate it to others, and apply it to carry out actions and manipulate their environment. The research is organized into three separate but highly interrelated themes: perception and action, language learning, and language processing. Research in the area of perception and action spans the processes involved in the first stages of visual and auditory representation of spatial and spectral information, to higher order representations of more complex attributes, to the storage and retrieval of such representations by the organism as they are used in goal-oriented actions. The study of language learning focuses on how children develop the abstract representations of language on the basis of their visual and auditory perceptions. The research in language processing combines investigation of formal systems with investigation of computational models, all in the context of empirical study of a wide range of natural languages. Significant features of the perception and action research are its increasing fidelity to actual neural computation and its sophisticated computational modeling and related potential for contributing to artificial intelligence technology. The language learning research has significant potential for technological spin-off in machine learning and automatic acquisition of lexical and grammatical information for language systems, crucial to the development of grammars sufficient for the robust analysis of unconstrained text. And the language processing research will have significant impact on the technological base for human- computer interaction, in particular the design of natural language interfaces for data base and expert systems and knowledge-rich systems in general. This Center will stimulate enhanced activity in precollege education and in the development of human resources.

摘要 宾夕法尼亚大学的这项提案请求资金建立认知科学研究科学技术中心。 该中心主任为 Aravind K. Joshi 教授。 认知科学研究中心汇集了来自许多传统学科（计算机科学、语言学、数学、哲学和心理学）的多元化且相互联系丰富的团队。 研究的目标是了解人类获取有关其环境的知识、存储和检索该知识、将其传达给他人以及应用其来执行行动和操纵环境的过程和机制。 该研究分为三个独立但高度相关的主题：感知和行动、语言学习和语言处理。 感知和行动领域的研究涵盖了空间和光谱信息的视觉和听觉表征的第一阶段所涉及的过程，到更复杂属性的高阶表征，再到生物体对这些表征的存储和检索。用于以目标为导向的行动。 语言学习的研究重点是儿童如何在视觉和听觉感知的基础上发展语言的抽象表征。 语言处理的研究将形式系统的研究与计算模型的研究结合起来，所有这些都在对各种自然语言的实证研究的背景下进行。 感知和行动研究的显着特征是其对实际神经计算的保真度不断提高，其复杂的计算模型以及对人工智能技术做出贡献的相关潜力。 语言学习研究在机器学习和自动获取语言系统的词汇和语法信息方面具有巨大的技术衍生潜力，这对于开发足以对无约束文本进行稳健分析的语法至关重要。 语言处理研究将对人机交互的技术基础产生重大影响，特别是数据库、专家系统和知识丰富系统的自然语言接口的设计。 该中心将促进加强大学前教育和人力资源开发方面的活动。
