    The directions for near-future development of artificial intelligence (AI) can be described in terms of four dichotomies: the use of reasoning versus the use of knowledge; the roles of parallel and of serial systems; systems that perform and systems that learn to perform; and programming languages derived from the search metaphor versus languages derived from the logical reasoning metaphor. Althou... View full abstract»

    The author studies the problem of determining the reliability of answers to queries in a relational database system, where the information in the database comes from various sources with varying degrees of reliability. An extended relational model is proposed in which each tuple in a relation is associated with an information source vector which identifies the information source(s) that contribute...

    Cited by:  Papers (7)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (672 KB)

    A concurrency control method is proposed for global transactions in a distributed heterogeneous database system. This method is applicable when the database sites are interconnected in a rooted tree fashion. It guarantees deadlock freedom in addition to serializability. A general architecture of a heterogeneous system is given. The global transaction manager (GTM) decomposes the global transaction... View full abstract»

    A neural network expert system called adaptive connectionist expert system (ACES) which will learn adaptively from past experience is described. ACES is based on the neural logic network, which is capable of doing both pattern processing and logical inferencing. The authors discuss two strategies, pattern matching ACES and rule inferencing ACES. The pattern matching ACES makes use of past examples... View full abstract»

    Cited by:  Papers (17)  |  Patents (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (800 KB)

    The authors propose a framework for using knowledge-based systems to integrate the heterogeneous multidatabases of computer integrated manufacturing (CIM). For each database, a corresponding knowledge-based system is designed for directing knowledge-processing of shared information. This one-to-one method reduces the complexity of the problem. Specifically, the structure, features, and knowledge r... View full abstract»

    A brief overview is given of the nature of present day artificial neural net computing and the authors emphasize the theme that in this mode of computing, knowledge is not represented symbolically, but in the form of distributed processing and localized decision rules. The authors propose that in neural-net computing, the processing is the representation. In other words, the very nature of the pro... View full abstract»

    A survey is given which focuses on research issues involving strategic planning and artificial intelligence (AI), including the nature of the formulation task, cognitive studies of strategic planners and computer-based support for strategic planning. The author reviews the research to date, and argues that, like traditional decision support systems (DSS) research, much of the potential for future ... View full abstract»

  • Rule acquiring expert controllers

    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (544 KB)

    A paradigm is developed for a controller to learn to control an environment by use of a benefit measure to judge the control. Rules are acquired that fire in a stimulus-response fashion for control, and rules continue to be acquired to adapt to an evolving environment. The model includes both knowledge acquisition and skill refinement through bottom-up (data driven) learning of the top-down contro... View full abstract»

    The author analyzes and compares the performance of two timestamp ordering concurrency control algorithms, namely, the basic and multiversion, for database systems. The multiversion algorithm improves the performance of the basic timestamp ordering algorithm by keeping multiple versions of data objects. The author discusses the performance enhancement in the multiversion algorithm over the basic a... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1228 KB)

    Combining knowledge present in multiple knowledge base systems into a single knowledge base is discussed. A knowledge based system can be considered an extension of a deductive database in that it permits function symbols as part of the theory. Alternative knowledge bases that deal with the same subject matter are considered. The authors define the concept of combining knowledge present in a set o... View full abstract»

    The authors examine whether one technique for group knowledge elicitation, focus groups, can provide different thoughts and judgments about a problem than individual interviews. The experimental situation was based on the resolution of an ill-structured problem by experienced subjects in a field setting. Videotaped scenarios were used to describe the situation for knowledge acquisition. Ten subjec... View full abstract»

    Intensional answers are conditions that tuples of values must satisfy to belong to the usual extensional answer of a query addressed to a deductive database. The authors review the concept of intensional answers and introduce a general method for generating them as logical consequences of the query and of deduction rules. The authors show how integrity constraints can filter out inadequate answers... View full abstract»
