| Abstract: | Attribute characteristic was judged by include-operation and join-operation of object sets corresponding to every attribute based on using include-operation to distinguish attribute characteristic.Thereafter,all the attribute characteristics were found and correspondingly a consistent set and a reduce set of concept lattice were obtainedf,rom which the aim to reducing the attributes of concept lattice was reached. |
