Towards an Agile E-Commerce

The alignment between business and IT plays a key role as changing business demands must be implemented immediately. To avoid misunderstandings and to lead to a better business-IT alignment we provide an ontology model, describing enterprise objects and their relations. As business rules guide or influence business behaviour, we use business rules which can be easily created and changed by business people. A system works directly with the ontology and the business rules. So, if changes occur, the business can express their changes and the IT system can react accordingly. As it easier for business people to express their knowledge and needs in a semi-formal way, we present a 3-phase procedure which helps to transform the semi-formal expressed knowledge into the formal representation needed for IT systems.

In this paper we introduce a model which supports the identification of the content the user is interested in and the shopping strategy of the current session. We use context information extracted from enterprise data, content data, the current and the historical behaviour of the user. This allows us to learn more about the interests and needs of the user. We monitor and analyze this content information at runtime and use it for the adaption of the web site during the user's navigation.

Ontologies for E-government

Theory and Applications of Ontology: Computer Applications, 2010

Although according to an e-government study 2006 nearly 50% of the examined services offered by EU states are fully available online (Capgemini, 2006) the majority of services on governmental web sites (especially of small municipalities) are in "stage 1" (information) or "stage 2" (interaction) 1. That is: providing online information about public services, e.g. opening hours or addresses of departments or provision of downloading of forms. Processing of forms, including authentication, ("stage 3"two-way interaction) and mainly "stage 4" (transaction, that is full case handling, decision and delivery e.g. payment) is reached only for a few services. Taking into consideration that only 20 basic public services (12 for citizens, 8 for businesses) have been evaluated in the study (Chevallerau, 2005)-out of more than 1,000 (e.g. in Switzerland approximately 1,200 services have been identified (eCH0015, 2006))-the necessity for new approaches is palpable. There are recent developments and trends on various levels that can have significant influence on the progress of e-government:-architecture: In a service-oriented architecture processes are supported by independent services that are made available on a network instead of having complex monolithic systems. They can be accessed via defined interfaces while implementation details are hidden to the user. This is particularly useful in administrative processes where various authorities are often involved.-technology: web services are a technology for implementing service-oriented architectures in an internet environment. They provide standards for identification

An enterprise model repository can improve sharing of enterprise knowledge and thus can exploit the use of the knowledge for various applications. In this work we present a framework for the organisation of enterprise models. The framework was derived from enterprise architecture frameworks. It distinguishes three dimensions: aspect, perspective, and modelling language family. For each of these dimensions we derive possible values. The framework can be used for enterprise repositories but also for knowledge exchange in a community as proposed by the Open Model Initiative.
