A Framework for Representing Knowledge Marvin Minsky MIT-AI Laboratory Memo 306, June, 1974. Reprinted in The Psychology of Computer Vision, P. Winston (Ed.), McGraw-Hill, 1975. Shorter versions in J. Haugeland, Ed., Mind Design, MIT Press, 1981, and in Cognitive Science, Collins, Allan and Edward E. Smith (eds.) Morgan-Kaufmann, 1992 ISBN 55860-013-2] FRAMES It seems to me that the ingredients of most theories both in Artificial Intelligence and in Psychology have been on the whole too minute, local, and unstructured to account–either practically or phenomenologically–for the effectiveness of common-sense thought. The "chunks" of reasoning, language, memory, and "perception" ought to be larger and more structured; their factual and procedural contents must be more intimately connected in order to explain the apparent power and speed of mental activities. Similar feelings seem to be emerging in several centers working on theories of intelligence. They take one form in the proposal of Papert and myself (1972) to sub-structure knowledge into "micro-worlds"; another form in the "Problem-spaces" of Newell and Simon (1972); and yet another in new, large structures that theorists like Schank (1974), Abelson (1974), and Norman (1972) assign to linguistic objects. I see all these as moving away from the traditional attempts both by behavioristic psychologists and by logic-oriented students of Artificial Intelligence in trying to represent knowledge as collections of separate, simple fragments. I try here to bring together several of these issues by pretending to have a unified, coherent theory. The paper raises more questions than it answers, and I have tried to note the theory's deficiencies. -
The Computational Attitude in Music Theory
The Computational Attitude in Music Theory Eamonn Bell Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Graduate School of Arts and Sciences COLUMBIA UNIVERSITY 2019 © 2019 Eamonn Bell All rights reserved ABSTRACT The Computational Attitude in Music Theory Eamonn Bell Music studies’s turn to computation during the twentieth century has engendered particular habits of thought about music, habits that remain in operation long after the music scholar has stepped away from the computer. The computational attitude is a way of thinking about music that is learned at the computer but can be applied away from it. It may be manifest in actual computer use, or in invocations of computationalism, a theory of mind whose influence on twentieth-century music theory is palpable. It may also be manifest in more informal discussions about music, which make liberal use of computational metaphors. In Chapter 1, I describe this attitude, the stakes for considering the computer as one of its instruments, and the kinds of historical sources and methodologies we might draw on to chart its ascendance. The remainder of this dissertation considers distinct and varied cases from the mid-twentieth century in which computers or computationalist musical ideas were used to pursue new musical objects, to quantify and classify musical scores as data, and to instantiate a generally music-structuralist mode of analysis. I present an account of the decades-long effort to prepare an exhaustive and accurate catalog of the all-interval twelve-tone series (Chapter 2). This problem was first posed in the 1920s but was not solved until 1959, when the composer Hanns Jelinek collaborated with the computer engineer Heinz Zemanek to jointly develop and run a computer program. -

Origins of the American Association for Artificial Intelligence
AI Magazine Volume 26 Number 4 (2006)(2005) (© AAAI) 25th Anniversary Issue The Origins of the American Association for Artificial Intelligence (AAAI) Raj Reddy ■ This article provides a historical background on how AAAI came into existence. It provides a ratio- nale for why we needed our own society. It pro- vides a list of the founding members of the com- munity that came together to establish AAAI. Starting a new society comes with a whole range of issues and problems: What will it be called? How will it be financed? Who will run the society? What kind of activities will it engage in? and so on. This article provides a brief description of the consider- ations that went into making the final choices. It also provides a description of the historic first AAAI conference and the people that made it happen. The Background and the Context hile the 1950s and 1960s were an ac- tive period for research in AI, there Wwere no organized mechanisms for the members of the community to get together and share ideas and accomplishments. By the early 1960s there were several active research groups in AI, including those at Carnegie Mel- lon University (CMU), the Massachusetts Insti- tute of Technology (MIT), Stanford University, Stanford Research Institute (later SRI Interna- tional), and a little later the University of Southern California Information Sciences Insti- tute (USC-ISI). My own involvement in AI began in 1963, when I joined Stanford as a graduate student working with John McCarthy. After completing my Ph.D. in 1966, I joined the faculty at Stan- ford as an assistant professor and stayed there until 1969 when I left to join Allen Newell and Herb Simon at Carnegie Mellon University Raj Reddy. -

This represents a major step toward using LCF as a practical program verification system. Newey in his thesis used LCF to prove the partial correctness of the LISP 1.5 interpreter and began a project to prove the correctness of a LISP compiler (called LCOMO). This compiler is actually more than a toy in that it is used in the LISP course here at Stanford. This thesis as a whole represented a kind of case study which demonstrated our ability to check the correctness large LISP programs. Automatic Deduction - David Luckham, et al A successful new automatic programming system accepts descriptions of library routines, " programming methods, and program specifications in a high level semantic definition language?. It returns programs written in a subset of ALGOL that satisfy the given specifications. Experimental applications include computing arithmetical functions and planning robot strategies. Another system works with algorithms expressed in a higher-level language and automatically chooses an efficient representation for the data structure. It then produces a program that uses this representation. Representations considered include certain kinds of linked-lists, binary trees, and hash tables.

An Interpreter for the Programming Language Predicate Logic
AN INTERPRETER FOR THE PROGRAMMING LANGUAGE PREDICATE LOGIC Sten-Ake Tarnlund Computer Science Department University of Stockholm Abstract We describe an Interpreter for the programming language predicate logic. Some topics are; syntax and proof procedure, procedure evocation, function transformation, goal variation and interactive computational control. Introduction The development of programming languages has more and more relieved a programmer from machine control and details, giving him the power of ab stract reasoning and thus helped him to concentra te more on his problem. Kowalski [8,9] has convin cingly argued that predicate logic formalizes a man's thoughts and is a useful simple programming language for human problem solving. Consequently It is desirable to have predicate logic implemen ted on machines for practical programming. There is one implementation at the University of Aix- Marseille, PROLOGUE [2]. At the University of Stockholm we have implemented an interpreter in LISP 1,6 [11]. Syntax and Proof Procedure Flg.l. A connection graph. Each atom is The syntax of the language consists of connected to all other atoms with the Kowalski's procedural form [7] plus a control same name occurring on opposite sides of structure consisting of an ordered procedure, or the arrows, provided that they can be dered procedures and computational consequences matched i.e., unified (12).

The connection graph is indipendent of the Kowalski's procedure form order the programmer presents his statements. De pending on one's programming style (problem-sol A procedure is the only type of statement in ving) one can combine top-down, middle-out and the language.
