Title:
ANAPHORA RESOLUTION METHOD AND ELECTRONIC DEVICE AND COMPUTER-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/073664
Kind Code:
A1
Abstract:
The present application relates to big data analysis and provides an anaphora resolution method, comprising: performing word segmentation on a text to obtain a referent set and a candidate antecedence set; establishing feature vectors between referents and antecedents according to a feature index; simulating classification situations of referents, weight matrices and subsets of the candidate antecedence set, and inputting the feature vector corresponding to each classification situation into a classification model to obtain the weight matrix and a candidate antecedent subset corresponding to each referent; using a sequencing model to sequence, according to a set rule, the candidate antecedents in the candidate antecedent subset to obtain the antecedent and a weight corresponding to each referent; in clustering decision making, considering a sequencing model weight and clustering different referents referring to the same antecedent to obtain a referent cluster. Further provided in the present application are an electronic device and a computer-readable storage medium. The present application introduces, by overlaying models, anaphora resolution which combines referent pair information and entity level information, improving identification accuracy.
