My intent was twofold: 1 to demonstrate that one of the distinguishing features of cybernetics might be that it could legitimately have multiple definitions without contradicting itself, and 2 to stimulate dialogue on what the motivations intentions, desires, etc. Duke University Press: Engineering Cybernetics , Preface vii.

McGraw Hill, Retrieved 8 January Introduction to Cybernetics. New York: Academic Press. Retrieved 13 August The two movements coexisted for roughly a de- cade, but by the mids, the proponents of symbolic ai gained control of national funding conduits and ruthlessly defunded cybernetics research. This effectively liquidated the subfields of self-organizing systems, neural networks and adaptive machines, evolutionary programming, biological computation, and bionics for several decades, leaving the workers in management, therapy and the social sciences to carry the torch.
Boulding eds. Social Sciences. September Cambridge University Press. At some future date it may appear as a joke of history that socialist countries learned at long last to overcome their prejudices and to dismantle clumsy planning mechanisms in favour of more effective market elements just at a time when the rise of computers and of cybernetics laid the foundation for greater opportunities in comprehensive planning.

Other federal contracts enabled Dragon to improve its technology. In , Dragon received a contract from DARPA for work on machine-assisted translation systems, and in , Dragon received a federal Technology Reinvestment Project award to develop, in collaboration with Analog Devices Corporation, continuous speech recognition systems for desktop and hand-held personal digital assistants PDAs. Late in , the Bakers realized that improvements in desktop computers would soon allow continuous voice recognition. They quickly began setting up a new development team to build such a product. To finance the needed expansion of its engineering, marketing, and sales staff, Dragon brokered a deal whereby Seagate Technologies bought 25 percent of Dragon's stock.
By July , Dragon had launched Dragon Naturally Speaking, a continuous speech recognition program for general-purpose use with a vocabulary of 23, words. The package won rave reviews and numerous awards.

IBM quickly followed suit, offering its own continuous speech recognition program, ViaVoice, in August after a crash development program. By the end of the year, the two companies combined had sold more than 75, copies of their software. The system can recognize the names of 13, different securities as well as major regional U. These devices translated spoken English phrases into corresponding Serbo-Croatian or Russian phrases.
Although most founders of the AI field continued to pursue basic questions of human and machine intelligence, some of their students and other second-generation researchers began to seek ways to use AI meth-. Their initiatives were important, not only in their own right, but also because they were indicative of a gradual but significant change in the funding environment toward more applied realms of research.
Developed in part with an initial research grant from the National Aeronautics and Space Administration in anticipation of landing unmanned spacecraft on other planets , but also picked up under DARPA funding, DENDRAL used a set of knowledge-or rule-based reasoning commands to deduce the likely molecular structure of organic chemical compounds from known chemical analyses and mass spectrometry data. The program took almost 10 years to develop, combining the talents of chemists, geneticists, and computer scientists.
In addition to rivaling the skill of expert organic chemists in predicting the structures of molecules in certain classes of compounds, DENDRAL proved to be fundamentally important in demonstrating how rule-based reasoning could be developed into powerful knowledge engineering tools.
Its use resulted in a number of papers published in the chemistry literature.
Although it is no longer a topic of academic research, the most recent version of the interactive structure generator, GENOA, has been licensed by Stanford University for commercial use. The development of these pioneering expert systems not only constituted major achievements in AI but also gave both researchers and research funders a glimpse of the ultimate power of computers as a tool for reasoning and decision making. Moreover, the apparent success of these projects helped to touch off the rapid development of expert systems. Promoted by SAIL's Edward Feignbaum, expert systems became the rage in AI research in the late s and early s and a commercial tool in the s, when corporations were seeking to embody the knowledge of their.
Starting in the mids, numerous start-up AI companies began to appear, many with products akin to expert systems. Many such companies came and went, but some flourished. For example, Gensym Corporation, founded in by an alumnus of the Massachusetts Institute of Technology's Artificial Intelligence Laboratory, built a substantial business based on its G2 product for development of intelligent systems. More recently, Trilogy Development Group, Inc. This new firm, pcOrder. Many corporations committed substantial capital and human resources to the development of expert systems, and many reported substantial returns on these investments.
Others found that, as AI pioneer McCarthy had argued, these expert systems were extremely "brittle" in that a small development in knowledge or change in practice rendered such programs obsolete or too narrow to use. In one study of AI Office of Technology Assessment, , expert systems were singled out as evidence of "the first real commercial products of about 25 years of AI research" but were also criticized for "several serious weaknesses" that demanded "fundamental breakthroughs" to overcome. But expert systems represented a failure to meet expectations as much as a failure of technology.
They provided valuable help for users who understand the limitations of a system that embodied narrow domains of knowledge. One of the biggest problems with expert systems was the term itself, which implied a certain level of capability; a number of users started calling them knowledge-based systems to refer to the technology instead of the goal.
Despite these criticisms, work on expert systems continues to be published; some corporations with strong knowledge-engineering capabilities continue to report substantial savings from expert systems and have demonstrated a continued commitment to expanding their use. Expert-system shell programs continue to be developed, improved, and sold.
Estimates suggest that more than 12, stand-alone expert systems are in use Liebowitz, Moreover, small expert systems are being incorporated into other types of computer software, most of it proprietary. For the most recent participants' account, see Lindsay et al.

These ideas suggest, for example, that induction can be automated as a heuristic search; that, for efficiency, search can be broken into two steps—approximate and refined; that learning must be able to cope with noisy and incomplete data; and that learning multiple concepts at the same time is sometimes inescapable. The literature on these programs is extensive.
