Building Relationships for Critical Service-Learning

Modeling Service Relationships for Service Networks

The last decade has seen an increased interest in the study of networks in many fields of science. Examples are numerous, from sociology to biology, and to physical systems such as power grids. Nonetheless, the field of service networks has received less attention. Previous research has mainly tackled the modeling of single service systems and service compositions, often focusing only on studyi...

Service Graphs for Building Trust

Information systems must establish trust to cooperate effectively in open environments. We are developing an agent-based approach for establishing trust, where information systems are modeled as agents that provide and consume services. Agents can help each other find trustworthy parties by providing referrals to those that they trust. We propose a graph-based representation of services for mod...

Building Assessment Web Service from Question Type Learning Objects

In this paper we discuss the TestTool system as an established testing system model, the one that is being used in real educational settings and supports self-assessment as well as testing learning practices. We then elaborate how this learning object-based system is being re-engineered and extended within the context of Web service oriented architecture. Testing Web service implementation alon...

We depart from previous work where trust is defined as the relationship between commitment of action and instant observation of the actual actions being performed. Here we generalise the approach by assuming a time delay between the observati...
