Abstract

The invention relates to an anaphora resolution method for a dialogue system, and the method comprises the steps: encoding sentences received by the dialogue system, and obtaining a sentence matrix of the sentences; inputting the sentence matrix into a first classifier group to obtain a head index and a tail index of an ancestor of the sentence; obtaining an antecedent vector according to the head index and the tail index of the antecedent; performing dot product on the ancestor vector and the sentence matrix to obtain a correlation vector; inputting the correlation vector into a second classifier group to obtain a head index and a tail index of one or more idiograms of the sentence; extracting the antecedent from the sentence according to the head index and the tail index of the antecedent, and extracting one or a plurality of appendixes from the sentence according to the head index and the tail index of the one or the plurality of appendixes to obtain an anaphora resolution result. According to the method and the device, a plurality of antecedents corresponding to the same antecedent in the sentence can be identified, and more complete information is provided for subsequent dialogue content processing.

Description

technical field [0001] The present invention mainly relates to the field of natural language processing, and in particular relates to a method, device and storage medium for metaphor resolution used in a dialogue system. Background technique [0002] Referential resolution aims to identify many different representations of the same entity in a sentence. In the dialogue system of the smart cockpit, users often habitually use pronouns to refer to entities such as people, objects, concepts, etc. mentioned above to avoid repeated words and words appearing in the dialogue. For example, the user asks the voice assistant in the smart cockpit: "There was a national football game last night, how many goals did they score? How many own goals did they score?" In this sentence, "they" is an alternative expression for "national football". Usually we call the "national football" in the sentence an antecedent (Antecedent), and "they" as an anaphor (Anaphor). This kind of human intuition ...
