Abstract

Aspects of the present disclosure relate to automated ontology refinement based on query inputs and provided feedback. A query input is received for an ontology. Features of the query input are analyzed, wherein analyzation includes determining syntactical and semantic characteristics of the features of the query input. Based on the determined syntactical and semantic characteristics, ontological elements are classified for each feature of the query input. The ontological element for each feature of the query input is then compared to a set of ontological elements of the ontology. Based on the comparison, a response to the query input is received, along with a request for feedback regarding the response. Feedback is then received regarding the response. Based on the feedback, the ontology is analyzed to determine at least one deficiency of the ontology. The ontology is then refined to correct the at least one deficiency.

Dependent claims

A system comprising:

at least one memory component;
and
at least one processor, wherein the at least one processor is configured to perform a method comprising:
receiving, for an ontology, a query input;
analyzing features of the query input, wherein analyzing features of the query input includes:
determining syntactical and semantic characteristics for the features of the query input;
and
classifying, based on the determined syntactical and semantic characteristics, an ontological element for each feature of the query input, wherein the ontological element includes one of a concept, a relation, and an attribute;
comparing, the ontological element for each feature of the query input to a set of ontological elements of the ontology;
retrieving, based on the comparison between each ontological element for each feature of the query input to the set of ontological elements of the ontology, a response to the query input;
transmitting the response and a request for feedback regarding the transmitted response;
receiving feedback regarding the response;
analyzing, based on the feedback, the ontology to determine at least one deficiency of the ontology;
and
refining, based on the at least one determined deficiency of the ontology, the ontology to correct the determined at least one deficiency.

A computer implemented method for ontological refinement comprising:

receiving, for an ontology, a query input;
analyzing, by a natural language processor, features of the query input, wherein analyzing features of the query input includes:
determining syntactical and semantic characteristics for the features of the query input;
and
classifying, based on the determined syntactical and semantic characteristics, an ontological element for each feature of query input, wherein the ontological element includes one of a concept, a relation, and an attribute;
comparing, the ontological element for each feature of the query input to a set of ontological elements of the ontology;
determining, based on the comparison between the ontological element for each feature of the query and the set of ontological elements of the ontology, that at least one element of the query input is missing from the ontology;
identifying, based on the determination that at least one feature of the query input is missing from the ontology, the at least one element of the query input that is missing from the ontology;
transmitting, in response to a identifying the at least one element of the query input that is missing from the ontology, an error indication that the at least one element is missing;
and
refining the ontology to add the at least one element that is missing.
