<p>The present invention relates to a sentence summarization method using a dependency grammar syntax tree, which creates a new dependency grammar syntax tree by modifying a dependency grammar syntax tree of a sentence according to a given rule, and then summarizes the sentence using the new syntax tree. A sentence summarization method using a dependence grammar syntax tree according to the invention comprises: a first step, in which a first dependency grammar syntax tree is created by using a syntax analyzer based on rules; a second step, in which a second dependency grammar syntax tree is created by using a syntax analyzer based on the probability for words without having a dependency relation therefor because of ambiguity in the first step; a third step, in which a third dependency grammar syntax tree is created by combining the first dependency grammar syntax tree created in the first step with the second dependency grammar syntax tree created in the second step; a fourth step, in which a modified fourth dependency grammar syntax tree is created by using and applying an artificial intelligence model that identifies a 'REMAIN' operation for maintaining a node of interest for each node from the third dependency grammar syntax tree, a 'DELETE' operation for deleting a node of interest and all of its child nodes, or a 'CHILD_UP' operation for deleting a node of interest and then putting its child node in its place; and a fifth step, in which a summary is created from the modified fourth dependency grammar syntax tree.</p> |
