    News Article Classification Based on a Vector Representation Including Words’ Collocations

    No full text
    In this paper we present a proposal including collocations into the pre-processing of the text mining, which we use for the fast news article recommendation and experiments based on real data from the biggest Slovak newspaper. The news article section can be predicted based on several article’s characteristics as article name, content, keywords etc. We provided experiments aimed at comparison of several approaches and algorithms including expressive vector representation, with considering most popular words collocations obtained from Slovak National Corpus

    A fuzzy bat clustering method for ergonomic screening of office workplaces

    No full text
    A method for screening of company workplaces with high ergonomic risk is developed. For clustering of company workplaces a fuzzy modification of bat algorithm is proposed. Using data gathered by a checklist from workplaces, ergonomic related health risks are determined. Three clusters of workplaces with low, moderate and high ergonomic risk are determined. Using these clusters, workplaces with moderate and high ergonomic risk levels are screened and relevant solutions are proposed. By a case study this method is illustrated and validated. An important advantage of the method is reduction of computational effort and fast screening of workplaces with major ergonomic problems within a company

    Service Oriented Architecture Applied to Provide Inter-operability between Macedonian MoD and NATO

    No full text
    In this paper we present SOA (Service oriented architecture) that we are developing to enable interoperability between Macedonian Ministry of Defence (MoD) and NATO. First we give a brief overview of Service-Oriented Architecture (SOA) and an explanation of how it can be used for the Ministry of Defense purposes. MoD uses IEEE 1472 definition of an architecture description to define a standard approach to describing, presenting, and integrating a defense architecture that can be used with a service oriented approach to capability based planning. The principal objective of our work is to ensure that architecture descriptions can be compared and related across organizational boundaries, including NATO and multi-national boundaries. SOA can provide easier identifying of required capabilities, the ways (operational activities), the means (human or system services) and the conditions (under which capability is required)

    A Model for Fuzzy Logic Assessment of Real Estate Investment Risks

    No full text
    Assessing the real estate investment risks is a major issue for the responsible management and the sustainable regional development. The paper proposes a fuzzy logic model for complex estimation of the real estate investment risks, based on the available information sources and the expert knowledge. The fuzzy logic model is designed as a hierarchical system that includes several variables. This model is intended to be implemented as a Web service in a cloud computing environment as a next natural step for increasing the span and efficiency of real estate manager activitie

    A System Integrating Agent Services with JMS for Shared Battlefield Situation Awareness

    No full text
    This paper reports on work in progress on a prototype information dissemination and management system for a hierarchical military command structure. Each unit is provided with a suite of services that integrates three paradigms for collaboration, communicates with its neighbors, and directs its immediate subordinates. This paper emphasizes concepts largely ignored but critical for shared situation awareness. As a prerequisite for coordination, we focus on common knowledge. Something is common knowledge in a group if not only does everyone in the group know it but also everyone knows that eve-ryone knows it. Constraints on inter-unit communication motivated using, in one unit’s services, proxy agents for its subordinate units. This use of proxies amounts to a version of the psychological concept of theory of mind (the ability to attribute to others mental states often conflicting with our own), seen as a mechanism for achieving common knowledge

    Using a Fuzzy Emotion Model in Computer Assisted Speech Therapy

    No full text
    Affective computing – machine’s ability to recognize and simulate human affects – has become a main research field for Human Computer Interaction. This paper deal with emotion recognition within a CBST (Computer Based Speech Therapy System) for preschoolers and young schoolchildren. Identifying the emotions of children with speech disorders during the assisted therapy sessions requires an adaptation of classical recognition techniques. That is why, in our article we focus on finding and testing the best emotion representation model to be used in this narrow field. An experiment that validates our proposed approach and indicates the probabilistic coefficient matrix is also presented. The proposed emotion recognition framework can be seen as a future extension of our CBST – Logomon

    A Fuzzy System Model for Task Implementation in Extreme Programming Process

    No full text
    Software simulation enables us to see how a software process is working and gives indication on some of the parameters of the process. The implementation of the tasks in extreme programming software process was modeled using a fuzzy system in this study. The communication between pair programmers, writing unit tests and coding rules are defined as the inputs of the system, and implemented task as the output. The defuzzified output of this fuzzy system gives quantitative results on how good a task is implemented

    Towards Better Discoverability and Use of Open Content

    No full text
    Availability and open access to resources is an important factor in educational development, but not a sufficient solution by itself. Open educational practices need to be fostered by an appropriate supportive environment including discoverable and shareable content, combined with tools for adaptation and re-distribution. Although a number of open content resources have been created, the accessibility for end users remains low because resources are spread across different OER repositories. This paper is an attempt to respond to OER challenges by proposing an innovative architecture extending the set of features typical for portal OER repositories with social networking features and (re)publishing functionality

    Applied cognitive task analysis in the context of serious games development

    No full text
    Sophisticated Technology Enhanced Learning (TEL) instruments as training simulations and Serious Games (SG) don´t provide knowledge content in explicit form, but propose interactive solutions for learners to build their own skills and competences in close to real situations. Thus, expert knowledge should be implicitly embedded into design of SG and training simulations. The present paper will discuss the problem of expert knowledge elicitation for building SG, and will analyze the use of cognitive task analysis methods for SG. There will be discussed the use of Applied Cognitive Task Analysis (ACTA) as effective and time-efficient tool for codification of expert skills in the context of Serious games and complex TEL simulations

    Visualizing and Presenting Story Maps in TM4Book

    No full text
    This short paper focuses on the visualization and presentation of storylines and suchlike narrative information in TM4Book, a Topic Maps-based semantic annotation tool for creative writing and textual analysis. Drawing on common gestalt principles as well as notions from semiotics and current discourse theory, the paper proposes some general strategies for displaying visual “story maps” and making them interactive for the user
