Abstract
An anaphora analyzing apparatus is disclosed for automatically estimating an anaphora referential relation or an antecedent of a noun for use in a natural language sentence. A storage unit stores analyzed results outputted from an analyzer, and an antecedent candidate generator detects a target component required for anaphora analysis in accordance with the current analyzed results and the past analyzed results stored in the storage unit, and generates antecedent candidates corresponding to the target component. Then, a candidate rejecting section rejects unnecessary candidates having no potential for anaphora referential relation among the antecedent candidates by using a predetermined rejecting criterion, and outputs the remaining antecedent candidates. Further, a preference giving section calculates a predetermined estimated value for each of the remaining antecedent candidates by referring to an information table including predetermined estimation information obtained from a predetermined training tagged corpus, and gives the antecedent candidates preference in accordance with the calculated estimated value. Finally, a candidate deciding section decides a predetermined number of antecedent candidates based on a given preference in accordance with the preferenced antecedent candidates.
