    Analytical data modeling of investment project financing process
    (Information systems technology and its applications – 6th international conference – ISTA 2007, 2007) Godlevskiy, Mikhail D.; Moskalenko, Valentina V.; Kondrashchenko, Vladimir V.
    The present work is devoted to the research of investment projects’ financing issues. Within this paper a data analytical tool for an optimal financing schema computation on the basis of solving the multicriterion dynamical problem is being presented. The model reflects the interests of both company and investor receiving maximum profit from the project execution as well as selection of a priority source of financing on the basis of capital cost minimization principle. We have developed the software on Java in order to perform an automated computation of an optimal financing schema using the suggested algorithm. The developed software is a complete solution for working with project data, obtaining the results (in the text and chart views) and generating reports.

    Automated Coding of Qualitative Interviews with Latent Semantic Analysis
    (Information systems technology and its applications – 6th international conference – ISTA 2007, 2007) Feinerer, Ingo; Wild, Fridolin
    Coding and analysing qualitative interviews is one of several core techniques used in marketing research. Qualitative methods offer valuable information hardly gained by standard quantitative methods since open-ended questions and interviews provide deeper insight into customer demands. The main disadvantages of qualitative methods are their inherent subjectivity and their high costs. We tackle this problem by applying latent semantic analysis (LSA) in a fully automated way on transcripts of interviews and we propose two algorithms based on LSA. We evaluate the algorithms against two separate real-life cases taken from the automobile industry and from the Austrian mobile phone market. Thereby, we compare the machine results against marketing expert judgements and show that the algorithms proposed provide perfect reliability with appropriate validity in automated coding and textual analysis.

    Cluster Computing Using Orders Based Transparent Parallelizing
    (Information systems technology and its applications – 6th international conference – ISTA 2007, 2007) Pavlenko, Vitaliy D.; Burdejnyj, Victor V.
    This paper proposes a new approach to parallel applications development, showing high speed and low labour intensiveness of creating new parallel applications and parallelizing existing ones. The basic principles of the proposed technology are described. The possible ways of implementation of these principles are proposed. Usage of the technology is shown with a sample algorithm. The result of experiment is given to show high efficiency of proposed technology.

    Constructing POSE: A Tool for Eliciting Quality Requirements
    (Information systems technology and its applications – 6th international conference – ISTA 2007, 2007) Shekhovtsov, Vladimir A.; Kaschek, Roland; Zlatkin, Sergiy
    Quality requirements elicitation for new computer applications rests traditionally on interviewing stakeholders. That makes getting these requirements right more complicated than is necessary because the anticipated users not necessarily are good at talking about the kind of computer aid and its qualities they would appreciate. We suggest bypassing that problem by constructing and using POSE (parameterized online simulation environment). Within this environment, anticipated users can explore ways of computer support for their work; it then makes it easier to talk about a potential computerized aid and the qualities thereof. Using POSE also simplifies obtaining quantified scenarios related to the various system qualities. As a result, this environment aids in getting the quality requirements right.

    Evaluating PSI Ontologies by Mapping to the Common Sense
    (Information systems technology and its applications – 6th international conference – ISTA 2007, 2007) Keberle, Natalya; Ermolayev, Vadim; Matzke, Wolf-Ekkehard
    The paper presents the results of mapping of PSI Ontologies family to the foundational ontologies: WordNet, SUMO and DOLCE. The two main outcomes of the presented research are: reported manual technique may be used as initial evaluation of ontology claiming to be a golden standard for a new domain; and: usage of mentioned foundational ontologies for alignment of ontologies family of a given domain has shown differences between SUMO and DOLCE, two formal upper-level ontologies of common sense knowledge. The research reported was performed in the frame of our PSI project1.

    Exception Analysis in Service-Oriented Architecture
    (Information systems technology and its applications – 6th international conference – ISTA 2007, 2007) Gorbenko, Anatoliy; Iraj, Elyasi Komari; Kharchenko, Vyacheslav; Mikhaylichenko, Alexey
    Exception handling is one of the powerful means of achieving high dependability and fault-tolerance in service-oriented architecture (SOA). The paper introduces the results of experimental analysis of the SOA-specific exceptions and factors affecting availability and fault-tolerance of Web Services, implemented by use of different development kits. We discovered several types of failure domains and represent results of failures injection and exception analysis in SOA.

    Game Theory-based Data Mining Technique for Strategy Making of a Soccer Simulation Coach Agent
    (Information systems technology and its applications – 6th international conference – ISTA 2007, 2007) Milani Fard, Amin; Salmani, Vahid; Naghibzadeh, Mahmoud; Khajouie Nejad, Sedigheh; Ahmadi, Hamed
    Soccer simulation is an effort to motivate researchers to perform artificial and robotic intelligence investigations in a multi-agent system framework. In this paper, we propose a game theoric-based data mining approach to help the coach agent select the best strategy for each soccer player agent in order to gain the most probable payoffs.These payoffs are calculated both static and dynamic i.e. are taken from experience results that are stored in a knowledge-base or is learned knowledge during the game. In this work we have confined ourselves to a model in which opponent strategy remains static. We take advantage of a learning algorithm with a polynomial time complexity in the number of states of the opponent strategy modeled by deterministic finite automata.

    Informational-Analytical Decision Support Of Strategic Acceptance Process At The Enterprise
    (Information systems technology and its applications – 6th international conference – ISTA 2007, 2007) Moskalenko, Valentina V.; Moskalenko, Vladimir Y.
    In this paper decision support system for development of the commercial enterprise is considered. An algorithm for the construction of enterprise development trajectories is offered on the basis of the chosen strategy. System software development is carried out using Java; the database support is provided by MySQL. The software architecture is described using UML notation. Dataflow model is developed in BPWIN, and the conceptual data model is developed in ERWIN.

    Integrating Manufacturing System Simulation Development – A Methodological Framework
    (Information systems technology and its applications – 6th international conference – ISTA 2007, 2007) Mtaawa, Jamal; Basher, Zidan
    Today, discrete-event simulation (DES) use in the manufacturing industry has become widespread, but far from all companies use this technology.Often simulation is used on a `one-shot' basis only, or as a standalone tool, reflecting a low level of integration. At the same time, a majority of companies do not use simulation at all. It is argued here that these companies lack methodologies for adopting and integrating simulation into their manufacturing system development process. Also, simulation research on integration aspects often deals with specific functional, or data-level issues, such as integrating and connecting simulation to other systems and tools, rather than structural, hierarchical, and procedural integration aspects as part of a methodological approach. Furthermore, simulation use seems to lack strategic focus. Based on industrial experience, this paper presents the framework of a methodology for integrating discrete-event simulation into manufacturing system development.
