Abstract: A system, method, and computer-program product includes identifying a target hierarchical taxonomy that includes a plurality of distinct hierarchical taxonomy categories, extracting a plurality of distinct taxonomy tokens from the plurality of distinct hierarchical taxonomy categories, computing a taxonomy vector corpus based on the plurality of distinct taxonomy tokens, computing a plurality of distinct taxonomy clusters based on an input of the taxonomy vector corpus, constructing a hierarchical taxonomy classifier based on the plurality of distinct taxonomy clusters, converting a volume of unlabeled structured datasets to a plurality of distinct corpora of taxonomy-labeled structured datasets based on the hierarchical taxonomy classifier, and outputting at least one corpus of taxonomy-labeled structured datasets of the plurality of distinct corpora of taxonomy-labeled structured datasets based on an input of a data classification query.
