As more and more documents become available in electronic format, the use of hypertext systems is becoming more common as a way to organise information. However as the size of a hypertext database grows, the ‘lost in hyperspace’ problem may limit efficient and meaningful usage of hypertext systems. In order to increase local coherence at net level, authors should limit 'the fragmentation characteristics of hypertext’. These characteristics seem to be endemic to hyperdocuments and result from the segmentation of information into disjointed nodes. Fragmentation may result in a lack of interpretative context and thus lead to the impression that the hyper-document is an aggregation of loosely linked pieces of information rather then a coherent whole. In an attempt to understand a new node, readers try to extract information and relate it in context to other nodes that they have viewed. In this thesis we describe an application which incorporates an apprentice link editor to suggest candidate information/hypertext links for the hypertext author to validate. These ‘suggestions’ use node-to-node comparison and metrics to present the author with the most appropriate choices in adding a new node to the hypertext they are authoring. Although this project is intended to provide a hypertext author with the tools needed to enhance the construction of a large hypertext, the assumption of trusting the author, and the notion that the best quality control tool is a skilled author is never forgotten.
