Enhancing Concept Mapping Tools Below and Above to Facilitate the Use of Superimposed Information

In this paper, we describe ways of enhancing concept mapping tools to facilitate representation and use of superimposed information. Superimposed information refers to new interpretation of existing information and involves working with information at various document granularities (sub-document, complete document, and multi-document). We illustrate our approach by showing how enhanced concept mapping tools may be used with two superimposed applications: SIMPEL and Strand Maps.
