A first approach to the automatic generation of service graphs for building trust

Abstract

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.
