Abstract: In this paper, we study the algebra structures of EI algebra generated by some attributes in the information systems. In the framework of Axiomatic Fuzzy Sets (AFS) theory, many fuzzy concepts can be extracted by AFS fuzzy logic compound of the attributes in an information systems and the EI algebra can be established on all these fuzzy concepts. The order and build-up of the EI algebra generated by the attributes have been estimated and described. These results can be applied to discover and represent the knowledge connoted in the information systems.

Keywords: molecular lattices; AFS; fuzzy logic; information systems; sperner class; information attributes; algebra structures; EI algebra; axiomatic fuzzy sets.
