    A natural intelligence is not an isolated one; on the contrary, it is highly related with other natural intelligences. Consequently, an artificial intelligence could be conceived as non-isolated and “socially” related to others. In this context the author: defines the basic concepts to be employed; reviews the “social” relations and influences existing between natural intel... View full abstract»

    The orthogonal properties of input pattern pairs of bidirectional associative memory have been studied. We have investigated the situations where one or both of the input pattern pairs are not orthogonal. The paper reports three methods of overcoming the recall problems under nonorthogonal conditions. A comparison between them is included View full abstract»

    The aim is to fill the gap between theory and practice in the production of explanations by a system. One reason of this gap arises from the fact that a problem is often solved thanks to a cooperation between the user and the system, and both participants in the cooperation need explanations. Explanations essentially depend on the context in which the user and the system interact. Such contextuali... View full abstract»

  • Knowledge acquisition or requirements analysis?

    Publication Year: 1994, Page(s):63 - 68
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (448 KB)

    There are many parallels which can be drawn between the processes of requirements analysis and knowledge acquisition: both are communication-intensive, both involve studying procedures and rationalising the findings for use within a computer-based system, and so on. Practitioners in both spheres have recognised that these similarities exist. This paper discusses the techniques used in requirements... View full abstract»

  • Can AI accommodate imagistic expertise?

    Publication Year: 1994, Page(s):36 - 41
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (436 KB)

    After years of focussing almost exclusively on rather primitive symbolic forms of knowledge representation, AI has started a systematic attempt to design and implement a computational correlate to human diagrammatic representation and reasoning. However, a number of thinkers are on record as confidently claiming that such representation and reasoning is forever beyond a digital computer. Are such ... View full abstract»

  • A hybrid knowledge representation based on logical objects

    Publication Year: 1994, Page(s):153 - 158
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (464 KB)

    This paper presents a hybrid knowledge representation based on the framework of logical knowledge objects (LKO), which are viewed as abstractions with behaviors, state and inheritance. It accommodates the main features of various knowledge representations, such as rule, frame, semantic network and blackboard, while amalgamating logic programming and object oriented programming paradigms. Therefore... View full abstract»

    Since the first studies on language, argumentation has been considered, with very few exceptions, as a phenomenon which had to be accounted for only after the meaning of the sentences under consideration had been “extracted”. Formal logic is among the best known tools generally used to “extract” meaning from sentences. As a confirmation of a very ancient analogy between mea... View full abstract»

    Publication Year: 1994, Page(s):298 - 303
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (384 KB)

    An integrated knowledge-based system, RAISON, was developed for environmental applications, using expert system and neural network technologies. Practical considerations dictate that access and linkage with databases, spreadsheet, maps, documents, graphics and other modules are essential. It was found necessary to implement the expert system and neural network modules in the same software package,... View full abstract»

    Introduces the approach and technology of drawing-based solid-modeling based CAD. Understanding engineering drawings is a highly sophisticated inference process making use of geometry knowledge. We emphasise methods to reconstruct 3D models from 2D drawings, and representation/usage techniques for the knowledge that recovers the information lost in the process of 3D to 2D projection. The heuristic... View full abstract»

    Qualitativeness of software is one of major problems for establishing its scientific measurement environment in which engineers can measure their products objectively and in an engineering way. To deal with the qualitativeness, automated tools are essential that integrate systems' expertise represented in the forms of software components. Therefore, after introducing our on-going researches to bui... View full abstract»

    We present a framework for machine learning that is based on, or more accurately, inspired from, concepts taken from the natural process of biological evolution. Currently, there exist many such evolutionary computational approaches to machine learning. The approach presented differs radically from these approaches; by taking a very abstract and general viewpoint to the process of evolutionary com... View full abstract»

    This paper presents an approach to support the top-down development of knowledge based systems. We propose to use predefined knowledge elements for eliciting, structuring, and formalizing the knowledge. The predefined elements are arranged in a library. We differentiate between three types of reusable knowledge elements: generic problem solving methods (PSMs), generic concept taxonomies and templa... View full abstract»

    We developed a special technique, called equivalent shifting in three dimensions (ES3D) for rule matching in a weather forecasting expert system CME. ES3D is able to describe the evolving procedures of domestic systems fully and exactly in three aspects: strength, position, and concept. ES3D is able to overcome the well-known brittleness of the first generation expert systems, then enhances the ca... View full abstract»

    The clinical record is a primary support for the diagnostic process performed by physicians. The development of a clinical record management system can significantly improve the quality of patient care by properly supporting the physicians' tasks and, in particular, the diagnostic process. We address some key issues in designing a medical decision support system. Acquisition of medical knowledge i... View full abstract»

  • Solving of constraint satisfaction problems using join trees

    Publication Year: 1994, Page(s):159 - 164
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (384 KB)

    We provide a new constraint satisfaction system that extends the constraint network to an acyclic one, computes a join tree, and establishes the directional strong k-consistency before any attempt is made to construct a solution; after this, the variables are instantiated without any backtracking. This method is extremely efficient if the constraint network is acyclic and the number of variables p... View full abstract»

    In previous work (see Proc. AADEBUG 93, Springer-Verlag, 1993) we developed a generalised query minimisation based on minimum entropy technique for diagnosing incorrect answers in the context of program debugging. This approach is adapted from model-based diagnosis. In this paper the query minimisation has been explored further to source program debugging and to program diagnosis with missing answ...

    The work presented is the continuation of an earlier work by the authors, wherein the grammar rules based on the concept of grammatical relations for parsing simple Hindi sentences have been given (D. K. Lobiyal, G. V. Singh, 1993). In that analysis, only the sentences with simple verb phrase have been considered. The authors extend the grammar to account for sentences with compound, conjunct or c... View full abstract»

    The authors focus on the integration of symbolic and sub-symbolic knowledge for the execution of path-planning tasks in autonomous agents. Environmental knowledge is represented through a multilayered architecture whose different abstraction levels are identified by means of meta-knowledge for classification and clustering of distinctive places. The path-planning problem considered consists of det... View full abstract»
