Abstract
In this paper, from the viewpoint of granular computing, information granule and concept granule are introduced to information systems, and then structure of concept granules and their distance, concept granular entropy and significance degree are presented. The concept of concept granule-based granular lattice is proposed in information systems. The representation and operation rules of complete granular lattice are given. Moreover, some important properties and propositions about these concepts presented above are discussed as well, whose performances are shown through an illustrative example. Finally, a conceptual framework of knowledge retrieval with granular lattice using concept granules may help to understand the nature of granules and granular hierarchical structures, and further enlarge the application areas of granular computing.
