The rule extraction of formal decision contexts based on the four-way principle lattice is mainly discussed in this paper. First in the formal decision sense, we reject the four-way principle lattice and use the example to explain it. Secondly, under the specified formal decision framework, we address the extraction of rules and outline decision rules and rejection of the redundant law. Finally, we analyse the relationship between the classical lattice concept, the three-way lattice concept and the four-way lattice concept.
