ER 2000 Workshops on Conceptual Modeling Approaches for E-Business and The World Wide Web and Conceptual Modeling Salt Lake City, Utah, USA, October 9–12, 2000 Proceedings
The popularity and press surrounding the release of XML has created widespread interest in standards within particular communities that focus on representing content. The dream is that these standards will enable consumers and B2B systems to more accurately search information on the Web within these communities. We believe the expansiveness and diversity of the Web creates a need for a small set of...
A hot topic on the agenda of corporate management in order to improve the enterprise competitiveness factors concerns the operational, even continuos and rapid, transformation of business processes, support interoperability and integration with other business partners. The paper overviews though a simple case study concerning the definition of a virtual enterprise, the methodology M*-COMPLEX (extending...
The application of conceptual models that assure both the consistency and usability of Electronic Product Catalogs (EPC's) is a main concern in the e-commerce community, mainly due to the impact a correct design of such interfaces has on the final e-store sales figures. This article describes how the OO-HMethod web-interface modeling approach can be successfully applied to the design of Business to...
Visual-oriented process modeling concepts and languages used today often lead to modeling of “spaghetti-processes”. Thus, the process models are not applicable effectively in distributed, partially automated and dynamic scenarios. They also support permanent adaptation and composition of process models insufficiently. The approach of Generic Linear Business Process Modeling describes a meta model...
Innovative e-business projects start with a design of the e-business model. We often encounter the view, in research as well as industry practice, that an e-business model is similar to a business process model, and so can be specified using UML activity diagrams or Petri nets. In this paper, we explain why this is a misunderstanding. The root cause is that a business model is not about process but...
Market-based inter-organizational workflow management integrates workflow management and business-to-business (B2B) e-commerce; it is a novel approach to workflow management which regards workflows as goods traded on an electronic market. In this paper, we investigate modeling aspects of electronic workflow markets. The workflow marketplace is modeled as a federation of workflow systems. Providers...
In the forthcoming years, two factors will jeopardize the deployment of Web applications: supporting multi-device outputs and one-to-one personalization. These two factors will lead to an explosion of solutions, to be developed, maintained, and kept consistent; meanwhile, Web hosting companies will be subject to growing service demands and will be lacking the technical man-power required to master...
In this paper we analyze different abstraction and reuse mechanisms that should be used in Web applications to improve their evolution and maintenance. We first review the OOHDM approach for defining a Web application model, in particular the separation of the navigational model from the conceptual model. We next focus on abstraction and composition mechanisms in both models showing how to combine...
E-commerce, web-based booking systems, and on-line auction systems are only a few examples that demonstrate how web sites are evolving from essentially read-only information repositories to distributed applications. These new web applications blend navigation and browsing capabilities, common to hypermedia, with “classical” operations (or transactions), common to traditional information systems. The...
Due to the unstructured character of data on the web it is hard to find specific information when surfing over the web. Search en- gines can only rely their results on IR techniques available, and most of the time they lack the desired power in query formulation. Modelling data on the web, as if it was designed for use within databases, provides us with the necessary basis for enhancing the query...
This paper presents a method that bridges the gap between requirements elicitation and conceptual, interaction and navigation design for Web applications. This method is based on user scenarios, use cases, and a new graphical notation, called User Interaction Diagrams. From these specifications, it is shown how to derive a conceptual model, and then how to derive the navigational structure of a Web...
In this paper, we present a general methodological frame- work, called Wisdom (Web Based Information System Development with a cOmprehensive Methodology), for the development of Web-based information systems (WIS). Wisdom is generally applicable and supports the design and the development of a wide spectrum of WIS applicati- ons. This is achieved by defining the Wisdom framework as a family of inter-related...
The need for descriptive information, i.e., metadata, about Web resources has been recognized in several application contexts (e.g., digital libraries, portals). The Resource Description Framework (RDF) aims at facilitating the creation and exchange of metadata, as directed labeled graphs serialized in XML. In particular, the definition of schema vocabularies enables the interpretation of semistructured...
In the so-called Web information systems, the role of extracting data of interest from Web sites is played by software components generically known as wrappers. As a result, the existence of flexible tools for designing, developing and maintaining wrappers is crucial. In this paper, we present WByE (Wrapping By Example), a user-oriented set of tools for helping the user to build wrappers. WByE is...
A method for supporting WWW retrieval by constructing a flexible category structure adaptable to the user's search intention is proposed. The method uses categorization viewpoints as a priori knowledge, where a categorization viewpoint is a finite set of consistent category names. A set of documents retrieved by initial keywords is decomposed by categorization viewpoints and each decomposition is...
