- KonferenzbeitragCoordinating higher education as an e-government initiative(Information Systems Technology and its Applications, 5th International Conference ISTA 2006, 2006) Cherednichenko, Olga; Kuklenko, Dmytro; Zlatkin, SergiyGovernment plays a key role in providing higher education. It supplies policies and regulations, information to the society, administers funds and licensing, develops standards, etc. In the context of total e-Governing Ministries of Education of many countries initiated the creation of supporting information systems. These systems in most cases are limited to providing information resources of different kinds to the society by web-portals. Administering and coordinating functions are left out for some reasons. In this paper we discover the typical structure of higher education, different stakeholders involved in the process of providing higher education services, information and data flows. We discuss the key functions that information systems must support. And finally we propose the e-Government higher education reference model to be addressed when developing such information systems.
- KonferenzbeitragFragments for composing collaborative systems(Information Systems Technology and its Applications, 5th International Conference ISTA 2006, 2006) Hawryszkiewycz, I. T.; Henderson-Sellers, B.; Tran, N.Collaborative systems are characterized by groups or communities jointly working to accomplish some organizational goal. Members of the communities must coordinate their efforts to ensure that such goals are met. Development of collaborative systems can be facilitated by identifying common aspects of such coordination and by constructing product method fragments that can be composed into working systems. This paper uses a metamodel to provide a basis for such fragments, describing the metamodel and defining typical fragments.
- KonferenzbeitragFuzzy-logic modeling approach for system requirements management(Information Systems Technology and its Applications, 5th International Conference ISTA 2006, 2006) Tkachuk, M.; Godlevsky, M.; Zemlyanoy, A.; Gamzayev, R.
- KonferenzbeitragA generic ontology of rational negotiation(Information Systems Technology and its Applications, 5th International Conference ISTA 2006, 2006) Ermolayev, Vadim; Keberle, NatalyaThe paper presents the generic conceptual framework for modeling rational negotiation processes. The central piece of the presented work is the upper-level negotiation ontology. This ontology is designed to be capable to model the arbitrary types of negotiation dialogues by providing the upper-level namespace for that. The models of the specific negotiation types refine this namespace by providing the instances of its concepts, applying additional restrictions on the properties, possibly adding new subclasses and properties. The approach to model negotiations with the Generic Negotiation Ontology (GNO) is initially evaluated by applying to contracting negotiation type. The choice of the negotiation type for the evaluation is suggested by the fact that contracting negotiations are the typical encounters among the agents taking part in the simulation of a Dynamic Engineering Design Process (DEDP). This modeling activity is performed in the frame of our PSI project1.
- KonferenzbeitragAn investigation of the target environment for agile methods(Information Systems Technology and its Applications, 5th International Conference ISTA 2006, 2006) Strode, Diane; Tretiakov, AlexeiThe agile methods were investigated to determine the factors making up their target environment. A theoretical model of the target environment for agile methods was developed and then tested using a multi-case study. Data from nine software development projects, both agile and non-agile, was gathered from project leaders. Then a cross-case analysis of each factor in the theoretical model explored the relationship between each of the environmental factors and the extent of agile method usage. This led to a refined model of the target environment. The empirical data showed that specific environmental factors correlate with effective use of an agile method. We also report that methods are tailored for use, and that, although agile methods are distinct from ad hoc development, the extent of agile method use must be measured before conclusions from agile method studies can be considered valid.
- KonferenzbeitragA JXTA-based music information retrieval system(Information Systems Technology and its Applications, 5th International Conference ISTA 2006, 2006) Jung, Hyosook; Park, SeongbinIn this paper, we present a JXTA-based system for contents-based music information retrieval. The system finds matching melodies from a set of XML documents that encode music contents. The XML documents are stored in a native XML database and XPath query language is used to extract the information about the structure of music data. The matching algorithm utilizes the geometric hashing technique [Wo97] by analyzing geometric properties of both XML documents and music contents. The system preprocesses extracted music contents and stores the information about melody patterns in a relational database. When a user sends a query about a melody, it searches melody patterns that have similar geometric properties as the query melody.
- KonferenzbeitragMethod engineering: theory and practice(Information Systems Technology and its Applications, 5th International Conference ISTA 2006, 2006) Henderson-Sellers, B.Method engineering promotes the idea of constructing methodologies for information systems development by selecting and assembling method fragments from a repository. This repository needs first to be populated with selfcontained fragments derived from industry best practice and compliant with a given metamodel. A situational method is then constructed (by a method engineer) to exactly match the requirements of the individual organization and/or project. This paper briefly outlines both the theory of situational method engineering and its application in terms of industry case studies carried out over the last 5 years in Sydney, Australia in helping organizations to create agile and flexible methodologies, capable of maturing and improving over the years.
- KonferenzbeitragMultiple criteria ranking enterprises based on inconsistent estimations(Information Systems Technology and its Applications, 5th International Conference ISTA 2006, 2006) Pertovsky, Alexey B.The paper considers a technique for ordering objects that are described with many quantitative and/or qualitative attributes and may exist in several copies. Such multi-attribute objects may be represented as multisets or sets with repeating elements. Object ordering is based on the theory of multiset metric spaces and applied to ranking enterprises, which are estimated differently by several decision makers/experts under multiple criteria.
- KonferenzbeitragOptimization of data sets allocation in the distributed databases(Information Systems Technology and its Applications, 5th International Conference ISTA 2006, 2006) Lazdyn, Sergiy V.; Telyatnikov, Alexander O.This paper deals with the new method of solving the problem of data set allocation optimization problem in the distributed database systems. The method is based on the combined use of object model of the distributed database and modified genetic algorithm. The criterion for optimum is defined by the minimum total average time required to process queries and disseminate updates. The experimental research of the developed method has proved that the productivity of the information system can be increased by 30\% due to optimization of the dataset allocation without the need for additional expenses on hardware modernization.
