Prior to 1960, and still true in large measure today this application area had been the exclusive province of the analog computer. The initial motivation for integrating the ordinary differential equations characteristic of continuous system simulation models on the digital computer was one of accuracy; given enough time, solutions of essentially unlimited accuracy could be obtained from the digital computer. These accurate, but costly, solutions were then used as consistency checks on the many hundreds of solutions characteristic of a simulation study on a high speed electronic analog computer.","PeriodicalId":294588,"journal":{"name":"Proceedings of the December 9-11, 1968, fall joint computer conference, part I","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1968-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114608743","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}

It is widely agreed that very meaningful technological advances can be made by merging the things that a computer does best with the things that a human being does best. This is often discussed in terms of a man-machine symbiosis, cybernetics or \"interfaces.\" The shortcomings in all discussions of this sort are twofold: first, a characterization of problem attributes which necessitates the power of an interactive environment is missing; and, second, very few practical or even implementable applications are ever discussed.","PeriodicalId":294588,"journal":{"name":"Proceedings of the December 9-11, 1968, fall joint computer conference, part I","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1968-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133160828","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}

Perhaps the major obstacle to such development was the difficulty of getting pictures into and out of the computer. The character recognition systems developed in the fifty's were in general not applicable to biomedical image problems because of the restrictive nature of the input devices. High resolution image scanners with the ability to detect multiple shades of grey were required and while such devices became available in the early sixties, it was difficult to find biomedical applications that would justify their cost which was frequently in the half million dollar range.","PeriodicalId":294588,"journal":{"name":"Proceedings of the December 9-11, 1968, fall joint computer conference, part I","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1968-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124484970","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}

This has led to a growing interest in communicating with computer files directly in a natural language such as English. The natural language systems described in the literature are largely small-scale research vehicles dealing with small data bases of restricted subject scope. Giuliano (1965), among others, has questioned the generalization of these systems to wider universes of discourse. Developments in this area have been reviewed by Simmons (1966), and by Bobrow, Fraser and Quillan (1967). In contrast, the work in on-line data management has been more concerned with the efficient organization of structured data to allow for quick access and maintenance of large volumes of formatted information [see the reviews by Kellogg (1967), Climenson (1966), and Minker and Sable (1967)].","PeriodicalId":294588,"journal":{"name":"Proceedings of the December 9-11, 1968, fall joint computer conference, part I","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1968-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124738828","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}
