The invention discloses a semantic modeling and abstraction enhancing method for associated frequency calculation on the basis of a data atlas, an information atlas and a knowledge atlas, is mainly used for obtaining reasonable categories and object diagrams from initial requirement description and an application scene, and belongs to the cross field of distributed calculation and software engineering technologies. On the data atlas, a discrete entity, object, attribute and operation is expressed, the frequencies, which include a structure frequency, a time frequency and a space frequency, of each entity, object, attribute or operation can be recorded; on the information atlas, an interaction relationship between nodes is labelled, an interaction frequency, i.e., an interaction time is calculated, a plurality of nodes are integrated when the interaction frequency is greater than a set threshold value, and a generated new node is taken as an entity to continuously label the structure frequency, the time frequency and the space frequency; and on the knowledge atlas, the relationship among the categories on the knowledge atlas is subjected to further abstraction by a relationship abstraction rule, requirement expression integrity is supplemented, and development efficiency is improved.
