<p>A natural language analysis apparatus comprises: knowledge base means for storing first-type trees representing dependencies among words in sentences, and second-type trees representing taxonym relationships of words; table means responsive to entry of a word to output ID data of said first-type tree in which said word appears, node location data of said word in said first-type tree, and to output ID data of said second-type tree in which said word is contained as a hyponym; means for judging the structural ambiguity of an incoming sentence; means for extracting a candidate pair of modifier and modifiee for each possible dependency for a sentence judged to be ambiguous structurally; means for entering words comprising each said pair into said table means and for determining, on the basis of the output data, a path including said words at opposite ends and including some of the words appearing in the first-type tree; means for calculating a path distance for each said pair; and means for determining a most preferable dependency on the basis of said path distance calculated for each. <IMAGE></p> |
