EFFICIENT AND ACCURATE NAMED ENTITY RECOGNITION METHOD AND APPARATUS

摘要

A method for recognizing and extracting named entities in a natural language input text processing comprising: performing, by a compressed named entities recognition (NER) -model-based named entity recognizer, a first stage NER on the input text to generate a first stage determination of whether at least one named entity exists in the input text; if the first stage NER determines no named entity exists in the input text, performing, by a rule based named entity recognizer, a second stage NER on the input text to generate a second stage NER resu if the first stage NER determines at least one named entity exists in the input text, generating, by the compressed NER-model-based named entity recognizer, a first stage NER resu and integrating, by a NER result integrator, the first stage NER result and the second stage NER result to generate a final NER result.
