Named Entity Recognition Named entity recognition (NER) is a subset or subtask of information extraction. NER is used in many fields in Natural Language Processing (NLP), … Named Entity Recognition using spaCy. This task, called Named Entity Recognition (NER), runs automatically as the text passes through the language model. In the output, the first column specifies the entity, the next two columns the start and end characters within the sentence/document, and the final column specifies the category. Machine learning practitioners often seek to identify key elements and individuals in unstructured text. We decided to opt for spaCy because of two main reasons — speed and the fact that we can add neural coreference, a coreference resolution component to the pipeline for training. Named entity recognition (NER) is a sub-task of information extraction (IE) that seeks out and categorises specified entities in a body or bodies of texts. I took a sentence from The New York Times, “European authorities fined Google a record $5.1 billion on Wednesday for abusing its power in the mobile phone market and ordered the company to alter its practices.”.
