In this chapter, we consider the addition of negation to basic graphs..FCGs extend BGs with negation, but in a way that does not suit the approach to knowledge representation develope

An Application of Nested Typed Graphs: Semantic Annotation Basesed graphs. In the first section, semantic annotations are defined as a kind of metadata. Two applications, information retrieval and editing, are also briefly described, and the annotation-based resource retrieval (.) problem is stated. The main components of an . system are also presented. In the s
