Facilitating dynamic web service composition with fine-granularity context management

Multi-granularity context model for dynamic Web service composition

“…All ontology-based context models inherit the strength of normalization and formalization from ontologies, but are weak in the activity representation and lack the reasoning capabilities which are important for Web service composition. The granular context model (Niu et al, 2009) and the action-based context model (Niu et al, 2008) have been proposed in our preliminary work. In this paper, we will propose a systematic method to incorporate both the action-based attributes and the value-based attributes into the same framework, and to support the management of context information at different details.…”
