Abstract: A method executed by a computing device includes determining a set of identigens for each query word of a query to produce a plurality of sets of identigens. The method further includes interpreting, based on identigen pairing rules of a knowledge database, pairs of sequentially adjacent identigens of adj acent sets of identigens of the plurality of sets of identigens to determine a most likely meaning interpretation of the query and produce a query entigen group. The method further includes identifying a set of entigen variations associated with the query entigen group utilizing the knowledge database to produce an expanded query entigen group. The method further includes obtaining knowledge associated with the first entigen variation of the set of entigen variations.
