Abstract
A method for identifying errors associated with named entity recognition includes recognizing a candidate named entity within a text and extracting a chunk from the text containing the candidate named entity. The method further includes creating a feature vector associated with the chunk and analyzing the feature vector for an indication of an error associated with the candidate named entity. The method also includes correcting the error associated with the candidate named entity.
Claims20
A computer-implemented method, comprising:
- recognizing a candidate named entity within a text;
- extracting a first subset of the text that contains the candidate named entity;
- analyzing, with a classifier, one or more features of the first subset of the text to identify an error associated with the candidate named entity;
- and
- correcting the error associated with the candidate named entity.
A system comprising:
- a processor;
- and
- a memory storing instructions which, when executed by the processor, cause the processor to:
- recognize a candidate named entity within a text;
- extract a first subset of the text that contains the candidate named entity;
- analyze, with a classifier, one or more features of the first subset of the text to identify an error associated with the candidate named entity;
- and
- correct the error associated with the candidate named entity.
A non-transitory, computer readable medium storing instructions which, when executed by one or more processors, cause the one or more processors to:
- recognize a candidate named entity within a text;
- extract a first subset of the text that contains the candidate named entity;
- analyze, with a classifier, one or more features of the first subset of the text to identify an error associated with the candidate named entity;
- and
- correct the error associated with the candidate named entity.
