Abstract
A computer-automated method and system of providing a searchable knowledge base with decision-relevant attributes (including some subjective or sentiment-based attributes) for a plurality of individual items within a choice set are described. First, information (including texts) relevant to the plurality of individual items in the choice set is harvested from Internet sources. Next, normalized representations of statements are extracted from excerpts of the harvested texts that pertain to attributes of interest for the choice set, and corresponding scores for the attributes are derived from each of the normalized representations. The scores derived from the various harvested sources are aggregated for each attribute of each item. Finally, the knowledge base of the plurality of individual topics is generated.
