1. A computer-based method of expressing an input text to have a semantic meaning, comprising the steps of: receiving an input text expressed as a plurality of sentences, each of which sentences includes a plurality of words therein; parsing the input text using the link grammar methodology and lexicon, to determine a syntax within the input text, including linkages between the words; using a set of semantic rules to transform the syntax to a semantic rendering or meaning, wherein each rule maps a particular linkage type or words in the input sentence to a semantic relationship component, or to a concept node participating in a semantic relationship component, respectively, and wherein the set of rules can be executed in combination or in succession to transform the input text to a plurality of semantic relationships expressed as a conceptual graph and corresponding to the input text.
