    The author suggests a new focus on benchmarks for knowledge systems, following the lines of similar benchmarks in other computing fields. It is noted that knowledge systems differ from conventional systems in a key way, namely their ability to interpret and apply knowledge. This gives rise to a distinction between intrinsic measures concerned with engineering qualities and extrinsic measures relat... View full abstract»

  • A personal chronicle: creating better information systems, with some guiding principles

    Publication Year: 1989, Page(s):17 - 32

    The author identifies four guiding principles which have come into play in this work of creating information systems and tools to support information systems. The first principle, open-eyes, is used to characterize information systems that remain open to new information, and consequently can compensate for changes in their mission or inaccuracies in their execution of that mission. The second prin... View full abstract»

  • Knowledge representation in fuzzy logic

    Publication Year: 1989, Page(s):89 - 100
    Cited by:  Papers (198)

    The author presents a summary of the basic concepts and techniques underlying the application of fuzzy logic to knowledge representation. He then describes a number of examples relating to its use as a computational system for dealing with uncertainty and imprecision in the context of knowledge, meaning, and inference. It is noted that one of the basic aims of fuzzy logic is to provide a computati... View full abstract»

    Datalog, a database query language based on the logic programming paradigm, is described. The syntax and semantics of Datalog and its use for querying a relational database are presented. Optimization methods for achieving efficient evaluations of Datalog queries are classified, and the most relevant methods are presented. Various improvements of Datalog currently under study are discussed, and wh... View full abstract»

    The authors present an overview of cooperative distributed problem solving (CDPS), an emerging research area that combines aspects of AI (artificial intelligence) and distributed processing. CDPS can be used to study how a loosely coupled network of sophisticated problem-solving nodes can solve a complex problem which consists of a set of interdependent subproblems. Subproblems arise because of sp... View full abstract»

    The authors assess the possible impact of optics on database and knowledge base systems, focusing on storage, interconnection, and processing. Various types of optical disks and page-oriented holographic memories are discussed. In the interconnection section, data communication is discussed at a variety of levels. Under processing, applications involving optical content addressable memories, optic... View full abstract»

    The author discusses the likely evolution of commercial data managers over the next several years. Topics to be covered include the following: why SQL (structured query language) has become a universal standard; who can benefit from SQL standardization; why the current SQL standard has no chance of lasting; why all database systems can be distributed soon; what new technologies are likely to be co...

    The author first discusses the difference between a knowledge base (KB) and a database (DB), which seems to hinge on the `gray box' verses `black box' nature of the entries. He then discusses the need for a huge KB to break today's bottleneck in intelligent systems, i.e. their brittleness when confronted by unforeseen problems. That same brittleness-the representation trap-is what prevents multipl... View full abstract»

    The successes and failures of the Macsyma algebraic manipulation system are reviewed from the point of view of one of the original contributors. A retrospective examination is provided of some of the controversial ideas that worked, and some that did not. Input/output, language semantics, knowledge-adjunction, mathematical semantics, the model of the user, and other issues are considered. Possible... View full abstract»

    The authors characterize the notion of heterogeneous databases as the inevitable consequence of replacing the traditional data processing practice with modern database management. They articulate the current problems and future issues connected with the great proliferation and overwhelming use of heterogeneous databases and their DBMS (database management systems). They survey available DBMS solut... View full abstract»
