The invention discloses a data ordering method based on a similarity calculation method, which belongs to the field of data processing. The method includes the following specific steps: (1) setting of a data similarity calculation basis; (2) loading of data for similarity calculation; (3) data similarity calculation process on the basis of similarity setting; (4) display of a data similarity calculation result. Compared with the prior art, the data ordering method based on the similarity calculation method has the advantages that the data similarity calculation basis is set through the operation of an operator and data are ordered through calculation according to a similarity degree, so that the data are ordered according to similarity, moreover, the data with a high similarity degree are automatically identified, and thereby the data ordering method based on the similarity calculation method has high popularization and application value.
