1. A computer-implemented method for outputting textual descriptions of data fields in a data mining model in a selected language, the method comprising: receiving at a computer system an extension document corresponding to a data mining model, the model including a unique identifier associated with a textual description of a data field in the data mining model; storing contents of the extension document in a database of the computing system, the contents of the extension document having first and second entries associated with the unique identifier, the first entry including the textual description of the data field in a first language, and the second entry including the textual description of the data field in a second language; receiving a task request from a front-end application, the task request including input data for use with the data mining model; in response to the task request from the front-end application, invoking a back-end analytical engine to execute the data mining model based upon the input data of the task request; receiving a back-end model output from the back-end analytical engine, the back-end model output including information generated in response to the execution of the data mining model based upon the input data of the task request; inserting the first entry from the contents of the extension document into the back-end model output to produce an updated model output; and outputting to the front-end application the updated model output that includes the first entry from the contents of the extension document such that the textual description of the data field is output in the first language.

The method of claim 1 , wherein the first language is English and the second language is German.
