Abstract: The basic operations in the language processing are classified from viewpoint of the entity and the attribute respectively, and two sets of basic operations , i.e., Attribute-derived operation set and Entity alternation operation set, are defined systematically . The attribute-derived operation set consists of Single-Phase operation, Aggregate operation, Disaggregate operation and Split operation.The entity alternation operation set includes Create operation and Fill operation. These operations are the basis of designing the architecture of the language processing model and the language processing function component. They are also beneficial for building a more economic knowledge processing scheme and universal information description mechanism.
