Approaches for modeling graded spatial relations abound in the literature on image processing and on geographic information systems. In contrast, few proposals have addressed the use of degrees in application contexts where inference plays a central role. We argue that the use of degrees is nonetheless natural in such contexts, and may enhance the application potential of qualitative spatial re...

Web services are autonomous software systems identifiable by URIs that can be advertised, located, and accessed through standard-based XML messages (e.g. SOAP, WSDL, and UDDI) and transmitted via Internet protocols. Web services encapsulate application functionalities and information resources, and make them available through programmatic interfaces, as opposed to the typical interfaces provide...

Goal-Oriented Requirements Engineering (GORE) is considered to be one of the main achievements that the Requirements Engineering field has produced since its inception. Several GORE methods were designed in the last twenty years in both research and industry. In analyzing individual and organizational behavior, goals appear as a natural element. There are other organizational models that may be...

A frame-based knowledge base can be a very large network whose information content is difficult for developers and users to comprehend and manipulate. In the SAGE consortium that is creating the technological infrastructure required in developing enterprise clinical decision-support systems for guideline-based care, knowledge engineers and clinicians must collaborate to develop knowledge bases ...

The separation of view and model is one of the key concepts of ModelDriven Engineering (MDE). Having different views on a central model helps modellers to focus on specific aspects. Approaches for the creation of Domain-Specific Modelling Languages (DSML) allow language engineers to define languages tailored for specific problems. To be able to build DSMLs that also benefit from view-based mode...

Object-oriented database schemas are often deened by several future users of the planned database, where each user deenes a schema representing his/her view on the database; the complete database schema is deened by integrating these views in a subsequent step. Behavior of objects is often deened at two levels of detail: at the level of methods and at the level of object life-cycles that repres...

Information systems for highly skilled clerical workers present themselves as a collection of window-based processes with underlying procedures accessing databases. It is left to the users to continue or interrupt a certain piece of work or to switch from one application to another. Such system can be supported by three layers: a database layer, a dialogue layer and a presentation layer. In thi...

Retailers’ websites are an important interface between retailers and their customers. The various features and elements that retailers include on their websites play a critical role in attracting customers and ensuring their satisfaction with the online shopping process. By conducting a three-phased study, we eywords: ustomer satisfaction alient beliefs eb elements tructural equation modeling e...
