- KonferenzbeitragConstructing 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, SergiyQuality 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.
- 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.
- KonferenzbeitragModelling actors and stories in web information systems(Information systems technology and its applications, 3rd international conference ISTA'2004, 2004) Schewe, Klaus-Dieter; Thalheim, Bernhard; Zlatkin, SergiyThe design of web information systems (WISs) requires a clear picture of the intended users and their behaviour. WIS users are called actors and classified according to their roles, intentions and behaviour. This leads to various propositional and deontic constraints on the story space, i.e. the abstract specification of WIS locations and activities associated with them. The knowledge obtained from the modelling of actors can be used to personalise the story space to the needs of a particular actor.
- KonferenzbeitragThe process of developing a business processes assembler(Information systems technology and its applications, 3rd international conference ISTA'2004, 2004) Albertyn, Frina; Zlatkin, SergiyOrganizations require material resources, human resources, and business processes to produce goods and services. There is an available market for material resources as well as human resources. The key problem is however the availability of business processes. This paper discusses the development of the requirements for the process assembler, a system that we are going to develop, that will support its users to carry out the key activities regarding business processes. Furthermore, the paper introduces the heuristics for a process selection tool that guides the selection of a development methodology. The process assembler development process is then applied using a prototype of the selection tool, based on those heuristics. The prototype then provides guidance for selecting a suitable development process.
- KonferenzbeitragTowards Information Management System for Licensing in Higher Education: An Ontology-Based Approach(Information systems technology and its applications – 6th international conference – ISTA 2007, 2007) Cherednichenkoa, Olga; Kuklenkoa, Dmytro; Zlatkin, SergiyHigher education licensing, i.e. the process of granting permissions to provide certain educational services, is an important process of public administration. Governmental bodies handle licensing requests submitted by education providers regularly. Such requests are supplemented with large amounts of information that demonstrates the actual situation in an education provider. At present this process is paper based and involves a lot of manual labor. This situation is similar for other types of education, e.g. primary and secondary, as well as for many countries. We, therefore, aim to computerize this process by creating a universal licensing information system (LIS). We base our approach on a domain ontology that defines the main concepts in the licensing process. In this paper we show how licensing process works now and propose the ways to make it more efficient. Then, we envisage the usage models of LIS, identify its main business actors and use cases, and provide a high-level architecture of the system. Finally, we present a fragment of the domain ontology in higher education domain.
- KonferenzbeitragTowards selecting among business process modeling methodologies(Business Information Systems – 9th International Conference on Business Information Systems (BIS 2006), 2006) Kaschek, Roland; Pavlov, Roman; Shekhovtsov, Vladimir A.; Zlatkin, SergiyThe problem of selecting the business process modeling methodology best suited for the business process modeling task at hand is often hampered by the conditions under which the selection is made. In this paper we sketch the foundations of a framework for selecting business process modeling methods. We base this framework on the Analytic Hierarchy Process. We therefore use a hierarchy of characteristics of business process modeling methodologies for our selection approach. To demonstrate how our approach works we discuss its application to two business process modeling tasks. We have developed a software tool that implements our framework. We describe this tool briefly in this paper.
- KonferenzbeitragWhere ontology affects information systems(2003) Kaschek, Roland; Zlatkin, SergiyNicola Guarino has coined the phrase ontology driven information systems. This phrase appears to offer ontology based help and guidance for information systems development. In this paper we try to understand better whether, why and where ontology affects information systems. We briefly discuss what kind of help we would appreciate and identify domains of knowledge in information systems development that according to our point of view could benefit from such help. We briefly discuss the following five domains: universes of discourse, information systems resources, information space use, customers, and human inference making.
