Advanced hypermedia indexing of documents in a deductive database system

This paper presents the hypermedia model SemaLink that faces orientation and maintenance problems in large information networks with a knowledge-based approach. Documents are connected to a knowledge base. By means of queries to this knowledge base users locate documents effectively that serve as entry points for a further knowledge based hypermedia navigation. Rule-based virtual structures derive new hypermedia structures automatically. Data consistency is guaranteed by an object-oriented schema. As a generic model SemaLink is suitable for a wide range of applications. To achieve this SemaLink combines multimedia with deductive database systems.
