Realtime Ingestion via Multi-Corpus Knowledge Base with Weighting

An information handling system that serves as a question and answering (QA) system, the system comprising:

• one or more processors;
• a memory coupled to at least one of the processors;
• a network adapter that connects the information handling system to a computer network;
• and
• a set of instructions stored in the memory and executed by at least one of the processors, wherein the set of instructions perform actions of:
• ingesting a first set of sources into a first corpus;
• ingesting a second set of sources into a second corpus, wherein the second set of sources are a subset of the first set of sources, and wherein the second set of sources include updates to the first set of sources;
• receiving a question from a requestor;
• identifying a plurality of candidate answers to the question using one or more sources included in the first and second corpuses, wherein a weighting is associated with each of the candidate answers;
• determining whether the first and second corpuses have an overlapping source from which two or more of the candidate answers were identified;
• in response to determining the overlapping source, assigning a first candidate answer from the overlapping source in the first corpus with a lower weighting than a second candidate answer from the overlapping source in the second corpus;
• selecting one or more likely answers from the plurality of candidate answers, wherein the selecting is based on the weighting associated with the respective candidate answers;
• and
• returning the selected likely answers to the requestor.

A computer program product stored in a computer readable storage medium, comprising computer instructions that, when executed by an information handling system, causes the information handling system to perform actions comprising:

• ingesting a first set of sources into a first corpus;
• ingesting a second set of sources into a second corpus, wherein the second set of sources are a subset of the first set of sources, and wherein the second set of sources include updates to the first set of sources;
• receiving a question from a requestor;
• identifying a plurality of candidate answers to the question using one or more sources included in the first and second corpuses, wherein a weighting is associated with each of the candidate answers;
• determining whether the first and second corpuses have an overlapping source from which two or more of the candidate answers were identified;
• in response to determining the overlapping source, assigning a first candidate answer from the overlapping source in the first corpus with a lower weighting than a second candidate answer from the overlapping source in the second corpus;
• selecting one or more likely answers from the plurality of candidate answers, wherein the selecting is based on the weighting associated with the respective candidate answers;
• and
• returning the selected likely answers to the requestor.
