Abstract: For facilitating the discussion of cognitive cooperation based on group learning, a basic environment supporting cognition is proposed taking advantage of the ontology technology, and some basic concepts related to the environment are presented. Accordingly, an integrated environment supporting knowledge application is explored by ontology approach. Moreover, the knowledge flow is defined in formalization and the logical process engaged in cognitive cooperation is discussed under the integrated environment based on the flow relation and the theory of Markov decision processes. Finally, the conclusion and directions in future research are presented.
