Abstract

The embodiment of the invention provides an anaphora resolution method and device. According to the method, the antecedent candidate set corresponding to each training sample is determined, and the feature vector is constructed for each element in the antecedent candidate set according to the pronoun category in each training sample so as to reflect the semantic relationship between the sentencesand the antecedents, so that the advantages of the semantic relationship can be effectively exerted; and then, the feature vector of each element in the antecedent candidate set and the anaphora resolution result of the corresponding training sample are input into the maximum entropy model for training, so that anaphora resolution can be performed on the statement by adopting the anaphora resolution model obtained by training. Therefore, the context semantic relationship of the anaphora can be fully utilized, so that the semantic relationship between the anaphora and the anaphora can be subsequently and effectively recognized, and the accuracy and recall rate of anaphora resolution are improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular, to a method and device for resolution of anaphora. Background technique [0002] Reference refers to the use of an anaphora in a text to refer back to a language unit mentioned before. Generally, the anaphora is called an anaphora, and the object or content referred to is called an antecedent. Usually the antecedent can be before or after the anaphoric. For example, if the antecedent can precede the anaphora, then the relationship between the anaphor and the antecedent is called an anaphoric relationship; if the antecedent can follow the anaphora, it is called a reverse anaphora. [0003] The resolution of anaphora is to determine the corresponding relationship between the anaphora and the antecedent. The same anaphora can also refer to different antecedents. The process of determining the antecedent of the anaphora is the process of resolution of anaphora. [0004] T...
