This paper discusses an email discovery and information retrieval tool based on formal concept analysis. The ECA program allows its users to navigate email using a visual lattice metaphor rather than a tree. It implements a virtual file structure over email where files and entire directories can appear in multiple positions in a given view. The content and shape of the lattice formed by the conceptual ontology can assist in email discovery. The system described provides more flexibility in retrieving stored emails than what is normally availableq in email clients and the approach can be generalised to any electronic document type. The paper discusses how conceptual ontologies can leverage traditional IR systems.
