The hyperedges and nodes are manipulated through a set of operators to compose new nodes and to instantiate new links dynamically, resulting in transient hypergraphs. These transient hypergraphs are virtual structures created in response to user queries and lasting only as long as the query session. The model provides a framework for general data access that accommodates user-directed browsing and querying as well as such traditional models of information and data retrieval as the Boolean, vector space, and probabilistic models. Finally, the relational database model is shown to provide a reasonable platform for the implementation of this transient hypergraph-based model of data access."
