Abstract: A method includes generating a new entigen group regarding trusted new information. The method further includes generating entigen groups from phrases of a document and determining whether an entigen group of the entigen groups has a most likely meaning similar to a most likely meaning of the new entigen group. When the entigen group has a most likely meaning similar to the most likely meaning of the new entigen group, the method further includes updating the entigen group based on the new entigen group. When the entigen groups do not include an entigen group having a most likely meaning similar to the most likely meaning of the new entigen group, the method further includes updating the entigen groups to include the new entigen group.

Abstract: A method includes generating a plurality of entigen groups from a set of phrases of a statement and identifying two plausible entigen groups based on a true meaning interpretation of the statement. The method further includes identifying a related entigen group based on a phrase of the statement and interpreting each of the two plausible entigen groups in light of the related entigen group to determine whether one of the two plausible entigen groups is a more likely interpretation of the statement than the other one of the two plausible entigen groups. When the one of the two plausible entigen groups is the more likely interpretation of the statement, the method further includes updating the one of the two plausible entigen groups using the related entigen group to produce an updated entigen group and adding the statement as the updated entigen group to a knowledge database.

Abstract: A method includes determining a set of identigens for each word of at least some words of a string of words of a query to produce a plurality of sets of identigens. The method further includes interpreting, based on a first knowledge database, the plurality of sets of identigens to produce a first entigen group and generating a first preliminary query response based on the first entigen group. The method further includes interpreting, based on a second knowledge database, the plurality of sets of identigens to produce a second entigen group and generating a second preliminary query response based on the second entigen group. The method further includes comparing the first and second preliminary query responses and when the first preliminary query response and the second preliminary query response are divergent, resolving inconsistencies between the first and second preliminary query responses to produce a final query response.
