Issues related to the use of various means of visual representation of the condition of a complex technological controlled facility, specifically, methods of cognitive graphics, are discussed. Nuclear-power facilities and oil-pipeline transportation systems are presented as two examples of complex facilities. The importance of the visual representation of the anomalous condition of controlled facilities while addressing the problems of condition diagnostics and making the appropriate decisions is discussed. Cognitive images that are applied by decision-support systems, the intelligent user interface of a nuclear-power-plant unit operator, and an oil pipeline system dispatcher are described. 相似文献

A new line of investigation that integrates studies on artificial intelligence and Internet technologies, which is known as
the Semantic Web, is presented. A review of the present state of research is given; problems on the establishment of knowledge
spaces on the Internet, the means and methods for the extraction of knowledge from texts in natural languages, as well as
questions on the use of knowledge spaces in the creation of applied intelligent systems operating on the Internet, are considered. 相似文献

A general approach to knowledge elicitation in interactive learning systems is presented which both improves a knowledge base by removing inconsistencies and extends the representation space for learning. This approach addresses the problem of learning "new terms" with interactive learning systems. Two methods that illustrate this approach are implemented in the learning apprentice system NeoDISCIPLE, using a concept-based representation that is very appropriate for learning. At the same time, the representation facilitates knowledge elicitation associated with human-oriented representations like, for instance, repertory grids. Both methods are consistency-driven in that they elicit knowledge from a human expert in order to remove inconsistencies in the knowledge pieces learned by NeoDISCIPLE. The input to these methods is an inconsistent rule learned by NeoDISCIPLE, together with the examples from which the rule has been learned. The elicitation process is characterized by a guided interaction with the human expert, who is asked to make relevant distinctions pertaining to concepts appearing in the positive and negative examples of the rule. The first method elicits concept properties through a goal-driven property transfer from one concept to another, and the second one elicits concepts using a goal-driven conceptual clustering. In both cases the elicited knowledge is used to improve the inconsistent rule while simultaneously extending the representation space for learning. 相似文献

The experience gained in the development of the system of simulation modeling of intelligent agent interaction (SMIAI) is
described. It is based on the general model of agent interaction proposed by G.V. Rybina, who developed the works on intelligent
dialog systems, including the well-known Popov’s communication model, in the late 1990s. The goal of SMIAI is to validate
the applicability of the proposed models, methods, and algorithms of intelligent agent interactions and their architecture
in developing MAS prototypes for different problem areas. The SMIAI architecture, support means for simulation experiments,
transmission and processing of messages, and other components are considered. Realized MAS prototypes for several applications
are presented as examples. The models of local, thematic, and global dialog structure for intelligent agents are presented
and the problems of intelligent agent communications behavior formation are analyzed. The creation of the models under consideration
by means of G2 and Microsoft Visual Studio is described. 相似文献

Efforts to represent knowledge effectively have been central to progress in various aspects of medical informatics. These efforts range from relatively simple "electronic textbooks" to fairly sophisticated knowledge-based systems, which function as well as, or even better than, human experts faced with similar problems. Knowledge bases have been developed in many fields, but the relatively limited domains and structured language of medicine, as well as the importance of information in the provision of good medical care, have made research in medical knowledge representation an area of intense activity. This paper reviews representative knowledge bases and knowledge-based systems in medicine: electronic textbooks such as PDQ and the Hepatitis Knowledge Base (HKB), rule-based systems such as MYCIN, causal models (e.g., CASNET), and hypothesis- or frame-based systems, exemplified by PIP and INTERNIST-1. The paper describes the relationships among divergent approaches and provides a sense of current and future trends. It examines problems in knowledge-based systems, particularly in knowledge representation and acquisition, and the responses to these challenges. The latter include the use of domain-independent software shells for constructing knowledge bases, the adaptation and use of previously existing knowledge bases, and multiple uses of the same knowledge base for different purposes. 相似文献

This article considers the task of building a universal integrated intelligent system and its interface for speech and gesture-activated control of robotic systems, including means of transport and aircraft. Several foreign publications are reviewed that present combined control systems and their results. The system is integrated with a knowledge base and a data base, makes use of artificial-intelligence elements, and bears on the generality of procedures of inputting, processing, and transferring different kinds of information. 相似文献

The paradigm of knowledge-based systems has become of practical interest to a broad variety of persons: software engineers, knowledge engineers and domain experts. Therefore, it becomes necessary to make explicit the underlying assumptions of the field. In this paper, the terms “knowledge” and “modeling” as they occur in texts on knowledge acquisition and machine learning are investigated. It is shown that the terms are used with very different meanings corresponding to different views of knowledge acquisition. The transfer view, the performance or building-blocks view, the knowledge-level or stepwise refinement view, and the constructive view of knowledge and its acquisition are described. The implications for designing systems which support a user in constructing a knowledge base are indicated. In particular, it is stressed that systems must support revisions of all modeling decisions if we want to prevent from the next bottleneck, the bottleneck of knowledge-base maintenance. 相似文献
