Dynamic Hyper-linking by Querying for a Fca-based Query System

This paper presents a mechanism for hyper-linking documents by search-terms. Search-terms are selected by the user interactively building a formal concept lattice. In order to explain this interface we give some background to Formal Concept Analysis and an example is developed which illustrates the use of the concept lattice. Selected search-terms are used to create hyper-links, based on term repetition. As the search-terms diier between queries, we need a mechanism from which to dynamically create the target hyper-linked HTML documents. Therefore , documents are stored in a structure which is based on a word-list rather than plain text format. The documents are represented as links between the individual words within the word-list. In so doing the word-list becomes a full-text-retrieval index into each word in each of those documents and therefore provides a good basis for the fast creation of an HTML document set from speciic queries by keywords. To have the words in a word-list from which the documents are created also allows easy classiica-tion of words which should be hyper-linked within speciic HTML documents. Furthermore, both documents and hyper-linking keywords are stored as well in this structure since any word in any document is indexed by the word-list.
