Context-aware knowledge base system

A computer system for generating a context-aware knowledge base, comprising:

• one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage devices, and program instructions stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, wherein the computer system is capable of performing a method comprising:
• extracting document object model (DOM) tag elements associated with one or more webpages;
• identifying and extracting webpage data associated with the extracted DOM tags;
• determining a context associated with the identified and extracted webpage data by detecting and extracting resource description framework (RDF) triplets in candidate DOM tag elements;
• ranking the extracted RDF triplets;
• validating one or more RDF triplets associated with the ranked RDF triplets;
• and
• connecting the validated RDF triplets to a knowledge graph associated with a knowledge base of the one or more webpages.

A computer program product for generating a context-aware knowledge base, comprising:

• one or more computer-readable storage devices and program instructions stored on at least one of the one or more tangible storage devices, the program instructions executable by a processor, the program instructions comprising:
• program instructions to extract document object model (DOM) tag elements associated with one or more webpages;
• program instructions to identify and extract webpage data associated with the extracted DOM tags;
• program instructions to determine a context associated with the identified and extracted webpage data by detecting and extracting resource description framework (RDF) triplets in candidate DOM tag elements;
• program instructions to rank the extracted RDF triplets;
• program instructions to validate one or more RDF triplets associated with the ranked RDF triplets;
• and
• program instructions to connect the validated RDF triplets to a knowledge graph associated with a knowledge base of the one or more webpages.
