New grammar comparison method boosts person name extraction accuracy

Researchers have developed a new method for Named Entity Recognition (NER) specifically for identifying person names. This technique involves comparing concordances from different local grammars to highlight differences, which aids in selecting the most effective grammar. In a case study on Portuguese texts, this approach improved the F-Measure for person name extraction by 6 points, reaching 76.86 and surpassing the previous state-of-the-art. AI
