Predictive analysis by example

An illustrative embodiment of a computer-implemented method for predictive analytic queries includes creating a user-defined predictive analytics query using a set of syntactic grammar that defines a correct syntax of the user-defined predictive analytics query including a created set of predictive analytics by-example vocabularies and a set of subject-specific by-example vocabularies forming a set of by-example vocabularies, wherein the set of syntactic grammar defines semantics of each syntactically correct predictive analytics query using the by-example vocabularies such that predictive analytics queries can be expressed with semantic precision using this constrained Natural Language Processing (cNLP) approach. The computer-implemented method further generates a predictive analytic model and runtime query, using the user-defined predictive analytics query, executes the runtime query using the predictive analytic model to create a result, and returns the result to the user.
