This is hardly disputed by anybody, but as soon one wants to understand what this context dependency means, or even more, what is context and how it relates to a situation then we have to admit that no common understanding exists on those categories. The objective of this...
This paper presents a situation-based service composition model for dynamic environments in which the characteristics of the surrounding environments are frequently changing. The main contribution of situation-based service composition model is: (1) to provide a concept of situations which specified the mutual affects of situated conditions and situated services, and (2) to provide an adaptation mechanism...
This paper proposes a rule-based reasoner system that adjusts the ratings based on the underlying siltation, thus, imposes situation awareness to the existing trust models. Furthermore, it helps the trust model to bootstrap by providing an estimation of trust value based on similar situations or similar trustees previously observed. The rules are automatically extracted from the history and encoded...
We propose an ontology-based approach for inferences linking trust information in two different situations. That reasoning process can augment the typically sparse trust information, by inferring the missing information from other situational conditions, and can better support situation-aware trust management. Our work is more comprehensive in comparison with other models and considers various aspects...
