Bidirectional Encoder Models for NER: How BERT is Revolutionizing Named Entity Recognition

Welcome back to the channel! In today’s video, we dive into how BERT, a bidirectional encoder model, is changing the game for Named Entity Recognition (NER) in Natural Language Processing. NER involves identifying key entities in text such as names, places, and dates, but context plays a crucial role. Traditional NER models processed text in one direction, often missing important context. Enter BERT — a powerful model that reads text both left to right and right to left, dramatically improving accuracy and context understanding.

We’ll break down how BERT and similar models like RoBERTa and DistilBERT outperform traditional models, achieve higher F1 scores, and are fine-tuned for NER tasks with minimal data required. Whether you're an NLP enthusiast or just curious about AI advancements, this video will give you the lowdown on how BERT is reshaping the future of NER.
