- Abstract
- Navigation problems in a hypertext migth be reduced, if mutiple, coherent views of the hypertext were available. Document outlines help readers appreciate the structure and meaning of the document. Proposes measures of syntactic and lexical balance in an outline and show in a sample of documents the degree to which these balances occur. Based on balance in an outline, a method for semi-automatically generating an alternative outline is applied to one textbook. The textbook with both its original and its alternative outline is availbale in hypertext, and subjects who were asked to evaluate this hypertext noted that the alternative outline would help readers compare concepts in the textbook

- Abstract
- When document components are classified and then recombined during document re-use, a semantic net may serve as the classification language. A theory of analogical inheritance, applied to this semantic net, guides the reorganisation of document components. Authors index paragraphs from various sources with node-link-node triples from a semantic net and then use programs to transverse the semantic net and generate various outlines. The program examines node and link names in deciding which path to take. Describes how these techniques helped in the re-use: parts of an existing book to write a new one

- Abstract
- The Many Using and Creating Hypermedia (MUCH) systems is based on the Dexter model and treats the storage layer as a semantic net. The MUCH system provides a numer of recommended link types for representing application domain concepts, such as thesauri, documents and annotations. users of the system are expected to use those link types in the course of authoring meaningful hypermedia. based on the logs of usage of the MUCH system over 2 years by over 200 people, contrary to the designers' expectations, users did not exploit the ability to type semantic links. Typically authors used the default link type regardless of their semantic intentions. When a link type other than the default type was chosen, that choice was often inconsistent with the way another user would able a similar link. The system has proven to be useful for authoring conventional documents. Authors, however, were not practically able to produce hypertext documents. Based on these experiences a new system, RICH (Reusable Intelligent Collaborative Hypermedia), has been designed and built which emphasizes rules for typing links and maintaining the integrity of the semantic net
