1. A sentence reconstruction method, for resolving word ambiguities in a selected language sentence structure, comprising the steps of:

  • (a) storing a sentence structure having a sequence of word positions with at least one word position represented by a word group including alternative word choices;

    (b) utilizing a stored word use rule set representative of relative frequency of particular word usage in said selected language to derive, for the word group for one of said word positions, probability values for word choices for said word position;

    (c) utilizing a stored language rule set representative of usage in said selected language to derive probability values for sequencing of individual word choices for said word position relative to at least one word choice for an adjacent word position in said sentence structure, said language rule set including rules in both of the following categories (i) rules based on transitional probability of use of particular word sequences, and (ii) rules based on probability of relative positioning of words of particular word categories in a sentence structure; and

    (d) selecting, by use of said probability values derived in steps (b) and (c), one word from each said word group for inclusion at a respective word position in a reconstructed sentence structure.
