Service Accelerator (SEA) system for supplying demand oriented information services

An information service system is proposed to satisfy the requirements for use, provision and guarantee of service, from the standpoints of end users, service providers and network providers. The service is defined according to three views: customization (who is requesting information service), situation (where and when they request it) and quality (how important the request is). These requirements are achieved by three basic techniques: (i) discernment of the service from the three views, (ii) broad action to access the related service providers or end users on the basis of the discernment, and (iii) synchronization to integrate the multiple information provided from the broad action. This information service system, called SEA (SErvice Accelerator), is realized as a service platform in an open environment so as to coexist with conventional systems and attain flexible services
