BERT (Bidirectional Encoder Representations from Transformers)
BERT (Bidirectional Encoder Representations from Transformers) is an AI model for natural language processing (NLP) developed by Google. Its defining characteristic is the ability to understand context from both directions simultaneously — reading text left-to-right and right-to-left at the same time. Compared to earlier one-directional models, BERT captures the meaning of sentences and relationships between words more deeply and accurately, delivering breakthrough results in tasks such as search engines, translation, and question answering. BERT is based on the Transformer deep learning architecture. It acquires general-purpose language understanding through two pre-training tasks: Masked Language Modeling (which predicts masked tokens) and Next Sentence Prediction. Key applications of BERT include: • Semantic understanding of queries in Google Search • Question-and-answer (Q&A) systems in natural language • Document classification, sentiment analysis, and summarization • Natural language understanding in chatbots and customer support • Use as a pre-trained model for multilingual translation and dialogue generation BERT serves as a foundation model for deep semantic understanding of natural language and has become the standard in modern NLP. It has also inspired a long line of derivative models, including RoBERTa, DistilBERT, and ALBERT.
