In this paper we discuss applying the CommonKADS methodology to the domain of Human Resource Management. Generally knowledge based systems are built for well defined, formal ized, "hard" domains. The area of Human Resource Management, however, is loosely defined and does not provide well-established theories or methods. We investigate the extent to which the approach advocated by CommonKADS...
Recently, Coloured Petri Nets (CPNs) have been widely used for modelling asynchronous discrete events exhibited in dynamic systems, while Fuzzy Petri Nets (FPNs) used for systems that involve approximate reasoning and uncertainty knowledge inference. In this paper, we propose a net-based structure, the so-called Fuzzy Coloured Petri Nets (FCPNs) to model both the dynamic behaviour and inexact production...
A new prototype neural net is presented to classify patterns from non-linearly separable and non-stationary datasets. Local density of class membership distribution function (cmd) is estimated with an hyperspherical semi-cover (prototypes) of input data, reflecting as well local homogeneity. The learning algorithm is able to learn time variations of cmd function using adaptive prototypes with adaptive...
In this paper a concept of an automatic programming system is characterized. According to this concept the computer on the basis of usees requirement expressed in the natural language performs the synthesis of the user program in Pascal from pieces of knowledge included in the knowledge base. In the paper the form of knowledge representation needed for automatic synthesis of user programs is introduced...
Concepts from social psychology, human factors, cognitive engineering, computer science, and industrial engineering are integrated to examine: the dynamics of trust between a user and an intelligent system; how trust impacts on the joint system performance; and how the interface impacts on trust.
In this paper, we stress the importance of considering evaluation from an overall viewpoint in order to produce higher quality Knowledge-Based Systems (KBS), that is, measuring attributes of products generated throughout the entire system life cycle rather than the final system alone. A framework for measuring typical products obtained during the development phases is proposed here. This measurement...
Case based reasoning and rule based deductive reasoning have long been considered as two different reasoning paradigms. To integrate the two, this paper first introduce a new form of knowledge, the relevance rule (R-rule), which represents knowledge about relevant relationship between attributes. The R-rule based reasoning paradigm is then described. The inductive learning of the R-rule is also briefly...
The Blackboard Architecture, originally developed for the system that permits the comprehension of the language HEARSAY II, has later been used in a great variety of domains and in various environments for the construction of systems. From the classic architecture of the HEARSAY II many applications, generalizations, extensions and refinements have been developed. In this paper we present REDSIEX,...
This paper reports an evaluation study for the specification of an average sized expert system for configuring elevator systems using the language KARL (Knowledge Acquisition and Representation Language). Two results have been gained in this study: (i) a formal model of the used problem-solving method (PSM) Propose-and-Revise has been developed and (ii) the adequacy of the language KARL for specifying...
Differential and Integral calculus are among. the subjects at high school ("Bachillerato") which cause the highest students' failing rate; therefore, new didactic elements for the teacher must be found. We have observed that expert systyem properties, such as justifying answers and finding another solutions, can be useful in designing expert systems which can facilitate the teaching-learning...
Assembly Instruction Manuals usually consist of both explanation and illustration. An expart who has rich knowledge on mechanical assemblies is able to under stand illustration without reading explanation. It is, how ever, difficult for a novice to read an instruction manual without referring to both of them. People may probably read explanation and see illustration alternately. It is difficult to...
Most published work in the field of pattern analysis, in our opinion underestimates the importance of system architecture or system development. When building large distributed systems both become a prerequisite in order to achieve the overall goal - a complex system solving a demanding task. In our paper we present the approach we have taken and the first solutions we found for an architecture integrat...
Existing mechanical design computational models have two fundamental drawbacks: partialness and shallowness. They are partial in that only some aspects of the design process are represented, and they are shal low in that the "what" aspect of the design process is often modeled without attaching design rationale to it. This limits their use as a representational tool. This paper proposes...
In this study a reactive navigation controller using fuzzy logic has been designed. The reactive controller deals with the uncertamty and ambiguity of the information the system (mobile robot) receives. The technique has been used on MOBIRO, an experimental mobile robot holding a set of five ultrasonic proximity sensors to extract the knowledge from its surroundings. The developed technique generates...
Consider the problem of a learning mechanism (robot, or algorithm) attempting to locate a point on a line.The mechanism interacts with a random "Oracle" ("Enviroriment") which essentially informs it, possibly erroneously, which way it should move. This problem is a generalization of the "Deterministic Point Location Problem" studied by Baeza-Yates et al. [1]. The first...
A method is presented for the automatic time detection of watches, where the hands are classified by a neural network. In order to reduce the overall cost of data collection, strict limits were imposed on the data collection time. This constraint severely limits the available amount of images, and poses the challenge to solve the hand recognition problem with a minimum amount of training and test...
The periodic re-localization of a mobile robot is necessary in order to reduce the uncertainty about its position and orientation when it moves. These uncertainties are due, among others, to integration errors of its internal sensors, such as odometers, accelerometers, etc. So, the localization of external references can be used to update the actual position and orientation of the vehicle; to this...
One of the most time-consuming phases of knowledge and model Wed systems development is related to the modeling of application domains. One approach to shortening this process is to reuse domain specific models during the life cycle of a product. A chemical distributor is used to demonstrai how standardized formalisms defined in ISO 10303 STEP) and lEC 1131 can be used when developing models for model...
This paper introduces a symbolic (non-arithmetic) algorithm for finding all the shortest paths in a directed or undirected graph, multigraph, or pseudograph from any specified initial vertex to any specified final vertex or to all other vertices. Dubbed SASP (Symbolic Algorithm for Shortest Paths), this breadth-first backtracking algorithm is based on a syntactical representation of the edges and...
This is an implementation proposal for a Structured Negotiation Environmen tfor Heterogeneous Agents (SNE-H) based on the Fishnmarket model. Our aim in this implementation is to explore design issues that may be relevant for the construction of a network communication infrastructure for cooperating heterogeneous agents. Hence, the Fishmarket multiagent system has been built on top of PVM package as...
