The concept of semantic schema was introduced in [8]. In this paper we propose a unidirectional transfer of knowl edge from a semantic schema to other semantic schema. We introduce a new kind of formal computations in se mantic schemas, that can use the conclusions obtained by another semantic schema. We define also the correspond ing semantical computations for such structures. We obtain a cooperation between semantic schemas based on a mul tilevel hierarchy of semantic schemas. Several particular cases of this cooperation are shortly described. In a sep arate section we describe an application that exemplifies the concepts defined in this paper. The last section relieves several open problems.
