- KonferenzbeitragUtilizing successful work practice for business process evolution(Business Information Systems – 9th International Conference on Business Information Systems (BIS 2006), 2006) Lu, Ruopeng; Sadiq, Shazia; Governatori, GuidoBusiness process management (BPM) has emerged as a dominant technology in current enterprise systems and business solutions. However, business processes are always evolving in current dynamic business environments where requirements and goals are constantly changing. Whereas literature reports on the importance of domain experts in process modelling and adaptations, current solutions have not addressed this issue effectively. In this paper, we present a framework that utilizes successful work practice to support business process evolution. The framework on one hand provides the ability to use domain expert knowledge and experience to tailor individual process instances according to case specific requirements; and on the other, provides a means of using this knowledge through learning techniques to guide subsequent process changes.
- KonferenzbeitragDescribing business processes with use cases(Business Information Systems – 9th International Conference on Business Information Systems (BIS 2006), 2006) Nawrocki, Jerzy; Nędza, Tomasz; Ochodek, Mirosław; Olek, ŁukaszBusiness processes can be described with diagrams, e.g. BPMN diagrams, or as text. Use cases are a text-based notation. They are semiformal: a business process is expressed as a sequence of steps and each step is presented in a natural language. In the paper two experiments are described that aimed at comparison of diagrambased and text-based notation. Moreover, we describe some extensions to use cases which we have found interesting when working on description of business processes based on use cases. Those extensions, among others, allow to describe actor metamorphosis and specify steps which must be performed before the main scenario is executed. The ideas described in the paper have been incorporated into UC Workbench – a tool supporting editing and animation of use-case-based models.
- KonferenzbeitragA framework for document-driven evolution of ontology(Business Information Systems – 9th International Conference on Business Information Systems (BIS 2006), 2006) Węcel, KrzysztofWe present a framework for updating ontology as new documents arrive. The framework consists of three main layers: extraction, internal storage and refinement. In the extraction layer axioms are extracted from the text by analyzing named entities, contexts and relations. We introduce the notion of temporal axioms, i.e. the axioms that are valid in a certain time interval. This information is then used to reason about ontology evolution when those axioms are added to an ontology. We also present cases for evolution and corresponding changing axioms. In refinement layer, final ontology for a given point in time is built.
- KonferenzbeitragConcept and implementation of an ontological document management system(Business Information Systems – 9th International Conference on Business Information Systems (BIS 2006), 2006) Simon, Eric; Ciorǎscu, Iulian; Stoffel, KilianIn this paper we describe a new architecture and implementation that allows the integration of a Document Management System with ontological support into a Web CMS. The architecture is motivated by the needs we identified in several real world projects. Our system is based on accepted open standards allowing anyone to replicate it or to use our system without restriction.
- KonferenzbeitragTechnique for reducing the number of rules in a temporal knowledge base(Business Information Systems – 9th International Conference on Business Information Systems (BIS 2006), 2006) Mach, Maria Antonina; Kalczynski, Pawel J.A knowledge base about any domain should satisfy some basic properties. One of these properties is completeness. Assuming that a knowledge base is temporal, that is, it contains explicit time references in its rules and facts, we may face a problem of an infinite number of possible premises, as the number of temporal references (e.g. in business documents) is unlimited. A technique for reducing the number of possible rules in a temporal knowledge base is proposed in this paper. This is achieved by transforming an infinite set of possible temporal rules into a finite one by mapping an infinite set of temporal references onto a finite set, and by automatic trimming of idiomatic phrases read from business documents. The technique for reducing the number of rules is presented and illustrated by an example.
- KonferenzbeitragRisks and risk management in ERP project - cases in SME context(Business Information Systems – 9th International Conference on Business Information Systems (BIS 2006), 2006) Ojala, Mika; Vilpola, Inka; Kouri, IlkkaEnterprise resource planning (ERP) projects are considered to be expensive, time-consuming, difficult to manage and risky. This paper presents how companies should consider and manage the risks in their ERP project. The focus in a qualitative case study is on small and medium-sized enterprises (SMEs) and it illustrates how the risks in the case firms are identified, analyzed and managed.
- KonferenzbeitragObject-oriented wrapper for semistructured data in a data grid architecture(Business Information Systems – 9th International Conference on Business Information Systems (BIS 2006), 2006) Kuliberda, Kamil; Wislicki, Jacek; Adamus, Radoslaw; Subieta, KazimierzThe paper addresses the problem of integrating data based on a XML-like semistructured model with a data grid architecture based on an object-oriented model. This work is continuation of the previous works on object-to-relational wrappers and covers a generic integration procedure for utilizing a native Lore query mechanism for retrieving data from XML data sources. A corresponding wrapper is founded on the concepts of the stackbased approach (SBA) and updatable views. The proposed architecture supports grid's transparency and allows a grid user to operate in an object-oriented environment through SBQL, a stackbased query language. The described wrapper makes it possible to employ the native Lorel query optimization mechanisms. A query entering the front-end of the wrapper (object-oriented business model) is transformed and rewritten according to the SBQL optimization rules incorporated in the wrapper and then evaluated in the native XML resource environment through the query language Lorel. The paper discusses architectural issues of such a wrapper and presents its idea through a concise example.
- KonferenzbeitragWhy do we actually need the Pi-calculus for business process management?(Business Information Systems – 9th International Conference on Business Information Systems (BIS 2006), 2006) Puhlmann, FrankThis paper discusses the applicability of a process algebra, the π-calculus, as a formal foundation for Business Process Management (BPM). We therefore investigate the π-calculus from a technical viewpoint based on current work in this area. The paper summarizes shifting requirements and discusses evolving theories behind BPM from the past over state-of-the-art to the future. The concepts and theories are concluded by an illustrating example highlighting why the π-calculus is a promising foundation for future BPM.
- KonferenzbeitragA security evaluation model for multi-agents distributed systems(Business Information Systems – 9th International Conference on Business Information Systems (BIS 2006), 2006) Ma, Chunyan; Concepcion, ArturoIn this paper, we propose a mathematical model for evaluating the security of multi-agent distributed systems. Using the developed security risk graph to model the system's vulnerabilities, the transition time on the shortest path between two vertices can be calculated to evaluate the estimated breach time. The diameter of the system is used to represent the security measure of the entire system. Thus, the security level of different systems can be compared.
- KonferenzbeitragDesigning infrastructures for reusing conceptional models – a general framework and its application for collaborative reference modelling(Business Information Systems – 9th International Conference on Business Information Systems (BIS 2006), 2006) Brocke, Jan vom; Thomas, OliverReference modelling offers numerous potentials for business engineering. These potentials lie essentially in providing means for reusing knowledge about the design of business processes considering both the potentials of application systems and business needs. However, reference modelling is as yet a rather young field of research and hardly ready for widespread operational use in business engineering praxis. Preliminary work focusing on the methodological aspects of model design may in particular be insufficient in supporting business engineers properly. The article at hand addresses this problem from a pragmatic perspective focussing on the designers` needs in specific modelling situations. Our work has revealed that comprehensive infrastructures are needed which provide various kinds of design support. Apart from methodological contributions, it is especially work in the fields of organisational and technological infrastructure design that is needed. In order to illustrate and evaluate the approach, we will present a study which applies the findings for the set-up of an infrastructure which makes use of collaborative techniques. The infrastructure is presented with respect to each building block including the presentation of a prototype. The pragmatic approach thus, gives way to collaborative reference modelling. This appears promising for making use of reference modelling in business engineering.
