Abstract

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.

First claim

What is claimed is:

1. A computer-implemented method for predictive analytic queries, the computer-implemented method comprising:
creating a set of predictive analytics by-example vocabularies;
creating a set of subject-specific by-example vocabularies, each comprising one or more nouns associated with a respective subject area, wherein the one or more subject-specific by-example vocabularies are based on a capability of one or more data sources;
generating a palette of vocabularies for constructing predictive queries, wherein the palette of vocabularies is based on the set of predictive analytics by-example vocabularies and the set of subject-specific by-example vocabularies;
constructing a user-defined predictive analytics query comprising the palette of vocabularies using a set of syntactic grammar that defines a correct syntax of the user-defined predictive analytic query;
wherein the set of syntactic grammar defines semantics of each syntactically correct predictive analytics query using the palette of vocabularies, such that the user-defined predictive analytics query is expressed with semantic precision using a constrained Natural Language Processing (cNLP) approach;
generating, by a computer processor, a predictive analytic model and runtime query, using the user-defined predictive analytics query;
executing the runtime query using the predictive analytic model to create a result; and
returning the result to a user.

2. The method of claim 1 , wherein creating the set of subject-specific by-example vocabularies further comprises using an assertion sub-method, wherein the subject-specific by-example vocabularies are derived from input that includes data source schema, metadata including ontology, and data instances.

3. The method of claim 1 , wherein creating the set of subject-specific by-example vocabularies further comprises:
collecting the subject-specific by-example vocabularies that are at least nouns, by using a subject-specific by-example vocabularies palette constructor; and
generating a set of subject-specific by-example vocabulary palette elements using an assertion capability in a subject-specific by-example vocabularies palette constructor for use in constructing by-example predictive analytic queries, wherein the assertion capability comprises at least two assertion types including an “is-a-kind-of” assertion, and an “is” assertion.

4. The method of claim 1 , wherein the user-defined predictive analytics query is a resultant sentence that is unambiguous in syntax and semantics, and therefore precise in execution.

5. The method of claim 1 ,
wherein generating the palette of vocabularies further comprises:
providing a set of palette elements with subject-specific by-example vocabularies and the set of predictive analytics by-example vocabularies, as palette elements for use to construct predictive analytics queries; and
collecting all palette elements in the set of palette elements into the palette; and

wherein constructing the user-defined predictive analytics query further comprises:
providing a canvas upon which a predictive analytics query is constructable by selecting subject-specific by-example vocabularies and predictive analytics by-example vocabularies from the palette elements of the palette; and
sequencing the by-example vocabularies to create a sequence for further processing.

6. The method of claim 1 , wherein generating the predictive analytic model and runtime query, using the user-defined predictive analytics query, further comprises:
receiving the user-defined predictive analytics query as input;
identifying the predictive analytics by-example vocabularies;
extracting the subject-specific by-example vocabularies from the user-defined predictive analytics query received as input;
validating correct sequencing of one or more by-example keywords using rules of the set of syntactic grammar; and
analyzing the predictive analytics by-example vocabularies in the user-defined predictive analytics query received, together with a data type of the subject-specific by-example vocabularies, to determine semantics of the user-defined predictive analytics query received, including an associated predictive analytics model and predictive analytics command to generate, wherein a generator uses decisions of a parser to perform at least one of constructing an instance of the predictive analytics model along with corresponding commands and selecting an existing model to reuse.

7. The method of claim 5 , wherein providing the set of palette elements further comprises:
providing subject-specific by-example vocabularies palette elements to the palette using a subject-specific by-example vocabularies palette element constructor; and
providing predictive analytics by-example vocabularies palette elements to the palette using a predictive analytics by-example vocabularies palette element constructor, wherein the predictive analytics by-example vocabularies palette element constructor further comprises at least predictive analytics by-example vocabularies selected from the group consisting of “given,” “how is,” “what combinations of,” “associated with,” “frequently occurs with,” “behaves similarly,” “which,” “what is,” “maximizes,” “minimizes,” “and,” “or,” and a combination thereof.

8. A computer program product comprising a non-transitory computer readable storage medium having computer readable program code embodied thereon, the computer readable program code executable by a processor to perform a method for predictive analytic queries, the method comprising:
creating a set of predictive analytics by-example vocabularies;
creating a set of subject-specific by-example vocabularies, each comprising one or more nouns associated with a respective subject area, wherein the one or more subject-specific by-example vocabularies are based on a capability of one or more data sources;
generating a palette of vocabularies for constructing predictive queries, wherein the palette of vocabularies is based on the set of predictive analytics by-example vocabularies and the set of subject-specific by-example vocabularies;
constructing a user-defined predictive analytics query comprising the palette of vocabularies using a set of syntactic grammar that defines a correct syntax of the user-defined predictive analytic query;
wherein the set of syntactic grammar defines semantics of each syntactically correct predictive analytics query using the palette of vocabularies, such that the user-defined predictive analytics query is expressed with semantic precision using a constrained Natural Language Processing (cNLP) approach;
generating, by a computer processor, a predictive analytic model and runtime query, using the user-defined predictive analytics query;
executing the runtime query using the predictive analytic model to create a result; and
returning the result to a user.

9. The computer program product of claim 8 , wherein creating the set of subject-specific by-example vocabularies further comprises using an assertion sub-method, wherein the subject-specific by-example vocabularies are derived from input that includes data source schema, metadata including ontology, and data instances.

10. The computer program product of claim 8 , wherein creating the set of subject-specific by-example vocabularies further comprises:
collecting the subject-specific by-example vocabularies that are at least nouns, by using a subject-specific by-example vocabularies palette constructor; and
generating a set of subject-specific by-example vocabulary palette elements using an assertion capability in a subject-specific by-example vocabularies palette constructor for use in constructing by-example predictive a
