Augmented hyperbooks through conceptual integration

We describe the automatic transformation of a traditional electronic document into a augmented, virtual document. After converting the content into a "small-scale" hyperbook structure with an ontology and textual fragments, we calculate semantic similarity relations between the concepts of this hyperbook and a reference hyperbook. We finally rebuild the document by involving the retrieved hyperlinks. The aim is to show that the integration process also works without a highly detailed ontological structure of the source document.
