Generation of Heterogeneous Semantic Annotations of XML Pages: A Multi-viewpoints Approach

Abstract

The semantic annotations presented in current research are based on consensual descriptions of domain knowledge which are used to generate a consensual interpretation of the resource content. Sometimes specialists in a domain want to enrich this interpretation with specific interpretations based on their specialties, consistent with the interpretations of other specialists. However, extant work cannot enrich consensual annotations with heterogeneous annotations. We propose an approach that constructs a consensual (global) annotation and then enriches the consensual annotation with heterogeneous (local) annotations, each of which is a specification of the global annotation. The heterogeneous annotations are consistent with the global interpretations and with one another. What is unique in our approach is that one element in a resource can be annotated with different specific concepts, based on different viewpoints. Our approach utilizes a multi-viewpoints ontology [1], with heterogeneity at the local level and consensus at the global level.
