Abstract
A method for processing a natural language communication includes a processor receiving a natural language communication and identifying, in the natural language communication, an ordered sequence of a plurality of word spellings of a natural human language. The processor performs constraint-based parsing of the natural language communication by reference to a consistent meaning framework (CMF) graph including a plurality of nodes each corresponding to a respective word meaning. The parsing includes scanning the phrase in multiple different parse scan directions and determining a respective meaning associated with each of multiple word spellings in a phrase of the natural language communication by reference to multiple constraints provided by multiple nodes in the CMF graph respectively corresponding to the word meanings.
