Service-oriented architecture (SOA) has emerged as a promising paradigm for the inter-organizational sharing of domain-specific capabilities. Perhaps an equally important emergence is the use of SOA to manage the sharing of disparate information within a distributed environment. SOA provides a platform for organizations to enable the user-driven advertisement, discovery, and retrieval of data. A major...
An experimental prototype system was created and used to investigate how information relevant to analyst queries, and constrained by a contextual model, can be found over a large information space. Agents employing the ant model sift through documents quickly using a transductive support machine classifier and return those meeting a classifier which is constantly refined through feedback from semantic...
The increasing competition in the mobile marketing market indicates that Mobile Marketing platform providers will be forced to integrate identity- and context information offered by the mobile network, in order to improve the efficiency of their applications. However, existing concepts/implementations only unassertively exploit available opportunities as well as insufficiently address emerging impacts...
While mobile TV in most parts of Europe is still in infancy, Italy as the first country of the European Union started to broadcast a mobile receivable TV program in June 2006. At the end of 2006 the number of subscribers reached 500,000. A classical direct revenue model was used. The acceptance of mobile TV is determined by the relation between the willingness to pay (WTP) for a service and the service...
Web service is essential in achieving dynamic business process. With the dramatically increased number of Web services advertised in UDDI, Web Portal or Internet, how to locate the best Web service according to a user's requirement is becoming more and more important, which calls for efficient and effective Web service discovery mechanism. Considerable efforts have been attained in solving this problem...
Service-Oriented Architecture (SOA) is an effective paradigm for publishing common features as services and reusing the published services in building applications. Therefore, reusability of services is a key criterion for evaluating the quality of services. The evaluation target for reusability in our model is the service, applied to both atomic and composite service. Reusability models for conventional...
Today, personalized services are lucrative for service providers and their customers. With their increasing pervasiveness and interconnection, however, customers show concerns about their privacy. If customers were to refuse the processing of their personal data in general, the economic potential of personalized services could not be realized. We claim that such scepticism is a direct consequence...
The development of mobile services becomes more challenging when context-awareness is taken into account. There are many problems in designing a successful context-aware mobile SOA. In this paper, we introduce the model of "dynamic capabilities" to study how systems can dynamically integrate, compose, and reconfigure internal and external competencies in responding to rapidly-changing environments...
Agent-based computing environments provide the capability to establish an enterprise of autonomous agents that collaborate and share information on common interests. Discovery of new data can alert users to changes in the information environment of importance to them. The goal of this research is to define an agent environment that models an organization's tacit knowledge. This document proposes a...
Electronic commerce has provided retailers with effective instruments to deploy one-to-one marketing over the internet. While the increasing use of sensors, RFID tags and other technologies enables the deployment of one-to-one marketing also in stationary retail stores, ini-tial experiments in realizing personalization in this setting have shown that customers' acceptance is low, as services require...
