Abstract:
1. A method of deducing the meaning of a sentence or phrase comprising the steps of: A) forming, a priori, a set of propositions each comprising at least an x, y, r and c object wherein x is a first object, y is a second object, r is a relationship between the first and second objects and c is a context of the relationship between the first and second objects; B) assigning, a priori, a weight to each proposition formed in step A to represent a confidence value of the validity of such proposition as compared to other propositions with the same first object; C) retrieving, upon receiving input of the sentence or phrase, applicable propositions by matching each word in the sentence or phrase to all propositions with the same first object; D) modifying the a priori weight of the propositions retrieved in step C by applying applicable heuristics through one or more of the steps of: E) applying the modified weights to the applicable propositions; and F) selecting the propositions with the highest modified weights; whereby the meaning of a phrase or sentence and its constituent words is deduced.
