Method and device for detecting similarity of data containing numerical value types

The invention discloses a similarity detection method and device for data containing numerical value types, and the method comprises the following steps: unifying base lines of numerical value type data in an original data resource and a data element result, and carrying out the numerical value standardization transformation after unifying the base lines; respectively carrying out character string conversion on the original data resources and the data element results after the numerical value standardization conversion; and calculating the similarity between the original data resources and the character strings corresponding to the data element results by using different distance criteria. According to the embodiment of the invention, a numerical value standardization transformation process and a process of respectively carrying out character string conversion on data resources and data element results are designed, and the similarity between the data resources and the data element results is calculated by ut
