A method includes obtaining a sequence of words of a query and identifying, for each word of the sequence of words, an identigen subset to produce a plurality of identigen subsets. The method further includes determining, in accordance with grouping rules, a query entigen grouping that includes a sequence of unique entigens, where an entigen of the sequence of unique entigens corresponds to an identigen of a corresponding identigen subset of the plurality of identigen subsets, and where the query entigen grouping corresponds to a meaning of associated with the query. The method further includes identifying a section of a knowledge base that substantially matches the query entigen grouping, where the knowledge base facilitates storage of knowledge as a multitude of entigen groupings. The method further includes determining an answer to the query based on the section of the knowledge base.
