Knowledge induction using corpus expansion

A computer program product for inducing knowledge from a knowledge graph, the computer program product comprising:

• one or more non-transitory computer-readable storage media and program instructions stored on the one or more non-transitory computer-readable storage media capable of performing a method, the method comprising:
• receiving a request, the request being indicative of a domain;
• determining a corpus corresponding to the domain, the corpus including data related to the domain;
• determining a quality of the corpus in generating the knowledge graph in which to induce knowledge relative to a quality threshold;
• as a result of the quality of the corpus not satisfying the quality threshold, determining a candidate expansion corpus to incorporate further data therefrom into the corpus relative to an expansion threshold;
• as a result of the candidate expansion corpus satisfying the expansion threshold, generating an expanded corpus by expanding the corpus with the further data;
• generating the knowledge graph based on the expanded corpus from which the knowledge is induced;
• and
• generating a response to the request based on the knowledge graph.

A computer system for inducing knowledge from a knowledge graph, the computer system comprising:

• one or more computer processors, one or more computer-readable storage media, and program instructions stored on the one or more of the computer-readable storage media for execution by at least one of the one or more processors capable of performing a method, the method comprising:
• receiving a request, the request being indicative of a domain;
• determining a corpus corresponding to the domain, the corpus including data related to the domain;
• determining a quality of the corpus in generating the knowledge graph in which to induce knowledge relative to a quality threshold;
• as a result of the quality of the corpus not satisfying the quality threshold, determining a candidate expansion corpus to incorporate further data therefrom into the corpus relative to an expansion threshold;
• as a result of the candidate expansion corpus satisfying the expansion threshold, generating an expanded corpus by expanding the corpus with the further data;
• generating the knowledge graph based on the expanded corpus from which the knowledge is induced;
• and
• generating a response to the request based on the knowledge graph.
