Other question is that when I try to pickle it: pickle.dump(chunker, open(“enr.pickle”, “wb”)). Named Entity Recognition Named entity recognition (NER) is a subset or subtask of information extraction. It involves identifying and classifying named entities in text into sets of pre-defined categories. It builds upon what you already learned, it uses a scikit-learn classifier and pushes the accuracy to 97%. Output: You can see that three named entities were identified. Named Entity Recognition, or NER, is a type of information extraction that is widely used in Natural Language Processing, or NLP, that aims to extract named entities from unstructured text. 2. please help…, Traceback (most recent call last): File “namedEntityRecognizer.py”, line 97, in
