DATA CURATION FOR CORPUS ENRICHMENT

Techniques for data curation are provided. A data set is received for ingestion into a question answering system, where the data set includes a first question and a first answer. Relevance of the first question is validated by comparing the first question to a first question cluster in the question answering system, and it is determined that the first answer satisfies predefined security criteria. The first data set is evaluated to identify a set of references, and a generalized data set is generated by replacing each respective reference of the set of references with a corresponding entity identifier. The first generalized data set is then ingested into the question answering system.
