A great variety of problem areas attempt to cope with Just such complexities. The importance of discovery and induction methods embedded within a pattern recognition program lies in their potential generality. The program, rather than the programmer, can be asked to discover and learn about the problem area. Pattern recognition should ultimately provide powerful techniques for use in such research areas as form perception, target recognition, language translation, theorem proving, game playing, and the testing of psychological models. Research on some of these applications is already underway. To the extent that discovery and induction can be successfully employed by the program itself, they should be used. This paper describes a program that makes a beginning attempt at such use.","PeriodicalId":167902,"journal":{"name":"Proceedings of the 1964 19th ACM national conference","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1964-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117191525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compilers have been written in this language for VALGOL I and VALGOL II. The former is a simple algebraic language designed for the purpose of illustrating META II. The latter contains a fairly large subset of ALGOL 60. The method of writing compilers which is given in detail in the paper may be explained briefly as follows. Each syntax equation is translated into a recursive subroutine which tests the input string for a particular phrase structure, and deletes it if found. Backup is avoided by the extensive use of factoring in the syntax equations. For each source language, an interpreter is written and programs are compiled into that interpretive language.","PeriodicalId":167902,"journal":{"name":"Proceedings of the 1964 19th ACM national conference","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1964-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116528513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Statistical Information Retrieval (SIR) system employs a -and-ldquo;co-ordinate concept-and-rdquo; with a logic based on the statistical probability that a desired document will be abstracted with a relatively high percentage of the identical or synonym keywords used in posing an inquiry concerning the document subjects. This approach to retrieval allows the use of an unlimited vocabulary, thus eliminating the need for a dictionary or thesaurus. The SIR programming incorporates a unique computing technique, vector manipulations and a search strategy which permit the system to operate efficiently on a large-scale computer. A bibliography and a representative example of the SIR program input and output are contained in an Appendix.","PeriodicalId":167902,"journal":{"name":"Proceedings of the 1964 19th ACM national conference","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1964-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126522901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The original idea came from the TEACH routine devised at Carnegie Tech. by A. J. Perlis and others. Our programs furnish data, check student answers in various ways, keep track of running time, and keep a -and-ldquo;grade book-and-rdquo; for the problems. They do not check the quality of the programming in any other way. In contrast to the TEACH routine, the Stanford routines, called GRADER1, GRADER2, etc., are written separately for each problem. The most flexible and useful system was used with the Burroughs 220 computer in the BALGOL language, a dialect of ALGOL 58, and will now be described. Each grader program was written as a BALGOL-language procedure. It was then compiled together with a procedure called BUTTERFLY, written by Roger Moore of Stanford. The result was a relocatable machine-language procedure, with a mechanism for equating its variables to variables of any BALGOL program, in just the form of the BALGOL compiler's own machine-language library procedures (SIN, WRITE, READ, etc.). Finally, the grader program was added to the compiler library tape for the duration of its use.","PeriodicalId":167902,"journal":{"name":"Proceedings of the 1964 19th ACM national conference","volume":"69 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1964-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127977760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
