A Comprehensive Guide to Named Entity Recognition (NER)
NLP: Helps machines understand the rules of language and helps make intelligent systems that can easily derive meaning from text and speech. Machine learning: Helps machines learn and improve over time by using various algorithms and training data. Any NER model has a two-step process: i) detect a named entity and ii) categorize the entity. The first step for named entity recognition is detecting an entity or keyword from the given input text.
