In addition to function storage for one computer run, it would be desirable to store analog functions for indefinite time intervals to permit table lookup. Typical accuracy requirements might be 0.1 to 0.5 per cent of half-scale at ten times the computer repetition frequency (10 cps to 1000 cps) with somewhat lower accuracy at higher frequencies.","PeriodicalId":395858,"journal":{"name":"AFIPS '64 (Spring)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1964-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131419474","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}

In so-called descriptor systems, where information is represented by sets of independent key words, this operation is relatively simple, since it consists of a comparison between the respective \"vertors\" of key words. In many retrieval systems it has been found necessary or expedient to use more complicated constructs for the identification of information. Notably \"role\" indicators are often added to identify various types of key words, and \"links\" specify a variety of relations between key words. A complete identification for a document or an item of information is often represented by a graph, consisting of nodes and branches between nodes, to identify respectively the key words and relations between key words. The matching of such information graphs with graphs representing requests for information is a relatively complicated and time consuming operation, particularly since the request structure can be made to match the information structure only partially and incompletely.","PeriodicalId":395858,"journal":{"name":"AFIPS '64 (Spring)","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1964-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115238620","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}

We are particularly concerned with those techniques which might be classed as predictive; the companion paper by Graham is concerned with other (\"nonpredictive\") techniques of analysis. Very broadly the techniques we will discuss operate as follows: Given a set of rules (Syntax Specification) for forming allowable constructs, eventually resulting in a statement (or sentence, word, program, etc.) of a language, we analyze a source statement in that language by guessing, or predicting, how the statement is constructed and either verifying that this is the case or backing up to try again, assuming some other method of construction. We keep a \"history\" of our attempts and when we have determined the exact way in which the statement is constructed we can use this \"history\" of its construction for further processing of the components of the statement.","PeriodicalId":395858,"journal":{"name":"AFIPS '64 (Spring)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1964-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125186184","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}

Ten years ago, in 1953, a large number of Electronic calculators were in use, but the general purpose stored program electronic computer was still quite rare.

A number of specially designed, mostly one of a kind, computers were in operation at Universities and government research centers. Commercially, a few Univac I computers had been delivered and were operating with great reliability at rather low speed. A few IBM 701's provided high speed but with very poor reliability.
