Abstract: A method and system is described for classifying and retrieving information using concept lattices. The system comprises a collection of electronic artefacts, a collection of attributes and a collection of relations associating the electronic artefacts with the attributes. The collection of attributes are arranged in a dynamic hierarchy that is dynamic and the system comprises mechanisms to consistently and scaleable update the relations between the electronic artefacts and the relations in a dynamic manner when changes in the system occur. The system further comprises a mechanism to display a subset of the electronic artefacts in a concept lattice and allow a user to easily interpret and discriminate the important attributes as they relate to the collection of electronic artefacts, relaxing or enforcing attribute search constraints depending on the volume of electronic artefacts that exists for each interacting attribute.
