In recent years, web services have turned out to be an emerging feature that is transforming how the web is conceptualized. Rather than considering the Web as a huge collection of static pages, for many purposes the WWW can be better understood as a collection of entities that provide and use services. In this setting, graph-based representations for modelling trustworthiness in a provider-consumer framework for agents have proven to be an attractive approach. However, computing and mantaining the underlying graph may be a considerably complex task. This paper presents a first approach towards computing such service graphs automatically on the basis of so-called concept lattices.
Our proposal is intended to enhance existing service-graph representations for modelling trust.
