On Construction Of Tri-Concept Lattices, S. El-Assar, A. Badawy, I. Gad, S. Emad Jan 2024

On Construction Of Tri-Concept Lattices, S. El-Assar, A. Badawy, I. Gad, S. Emad

Information Sciences Letters

The main point is to define the structure of a Tri-Concept lattice to deal with data given by different sources and represent it by less complex structures without loosing knowledge. We suggest the algorithm TRI-NEST to form the nested diagrams corresponding to the Tri-Concept lattices. Adding the ICE-T algorithm enables us to generate all frequently closed concepts, which leads to simplifying the Tri-Concept lattices and using the Iceberg Concept lattices as a reduction method to the big data while preserving all information.
