  • Event grammars: a modeling representation for business procedures

    Publication Year: 1989, Page(s):553 - 559 vol.3

    An alternative representation for modeling organizational procedures is proposed, called event grammars, which is based on the definite-clause grammar formalism used for natural-language parsing. A graphical counterpart, called event nets, is also introduced. In effect, a history of events is recognized as conforming to a particular procedure, analogous to the way in which a list of words is recog... View full abstract»

    Heuristics are developed for information scanning activities in large collections of information. These search heuristics are consistent with human information processing behavior identified in prior empirical research. They rely on available knowledge, and provide a guide for the design of computer-based systems which support information scanning. Conclusions are presented which describe how to i...

  • A logic model for text editing

    Publication Year: 1989, Page(s):543 - 552 vol.3
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (684 KB)

    A first-order logic Horn axiomatization of a text editor is developed showing how all commands are built upon the insert, delete, and character-retrieval operations. The authors describe an operational semantics for the representation of a text-editing system which is sound and complete with respect to the logic model. They illustrate the usefulness of the model and semantics by both implementing ... View full abstract»

    The authors develop an analytical model for determining the optimal rewriting time. They consider two rewriting strategies involving two different technologies. Several interesting propositions with managerial implications emerge from the analysis. These include the impacts of increasing maintenance requirements and unstructuredness of the technology on the optimal rewriting time, the differences ... View full abstract»

    Belief revision in standard rule-based systems is NP-hard, and it is necessary to resort to quasiprobabilistic belief languages which are quite problematic on normative grounds. The author presents a framework designed to study the Bayesian interpretation and cognitive appeal of these languages. He uses this framework to review some well-known and some recent findings, and comments on the merit of... View full abstract»

    Electronic messaging in an office environment is normally carried out in natural language. For a variety of reasons it would be useful if electronic messaging systems could have semantic access to (i.e. access to the meanings and contents of) the messages they process. Given that natural language understanding is not a practicable alternative, there remain three approaches to delivering systems wi... View full abstract»

    The authors focus on technological issues for a unifying GDSS (group-decision-support system architecture) architecture. A relational GDSS architecture using extended database concepts and an associated processing kernel or GDSS operating system (GOS) are set forth. The proposed architecture is sufficiently robust to represent existing and anticipated group decision support systems. Major benefits... View full abstract»

    A group decision support system should ideally be tailored to the needs of the group on a continuous basis. Since most groups are formed and disbanded frequently, it is usually not feasible to create a group decision support system tailored to meet the specific needs of each group unless there already exists an infrastructure within the organization's computer system to do so. The authors propose ... View full abstract»

    The author describes the design of a system for a business planning problem. A knowledge representation (KR) scheme is used to represent the user's image of the problem, and the procedures available-both user-directed processes (UDP) and computer-directed processes (CDP)-and in designing the logic of the CDPM. The CDPM uses a plan generator to generate several different types of plans. The history... View full abstract»

    The purpose of this empirical study was to examine one of the aspects of cognitive processes, namely, cognitive strategies, for multiple-criteria decisions. The results indicate that there are differences in performance, efficiency, and confidence due to the moderating effects of cognitive strategy, particularly when that strategy is interfered with. Attempts to accommodate decision-makers' cognit... View full abstract»

    The authors investigated the impact of a GDSS (group decision support systems) based on the stakeholder identification and assumption surfacing model for strategic planning impact analysis. A controlled laboratory experiment was used to compare the results of four-person groups which had GDSS support, comparable manual support, and no support.

    The author develops a nonlinear formulation of the topological design problem, and obtains a Lagrangean relaxation of the problem. The Lagrangean solutions provide lower bounds on the optimal solutions, which are further improved using subgradient optimization procedures. Heuristics are developed for generating feasible solutions to the problem. The quality of solutions generated by this heuristic... View full abstract»
