Natural Language Processing (NLP)
Discover a comprehensive roadmap to mastering natural language processing. From the fundamentals of NLP, classical tasks, and development tools to advanced techniques and real-world applications of NLP.
Introduction
Natural language processing (NLP) is a branch of artificial intelligence that deals with analyzing, understanding, and generating human language. It focuses on developing systems and algorithms that can process and understand natural language data, such as text and speech.
Some key aspects of natural language processing include:
-
Natural Language Understanding (NLU): This involves interpreting and comprehending the meaning of human language inputs, including tasks like named entity recognition, sentiment analysis, and text classification.
-
Natural Language Generation (NLG): This involves producing natural language outputs, such as text summaries, reports, or responses to user queries.
-
Machine Translation: Automatically translating text or speech from one language to another.
-
Speech Recognition: Converting spoken language into text.
-
Text-to-Speech: Converting written text into spoken language.
NLP combines various techniques from computer science, linguistics, and machine learning to solve problems related to human-computer interaction, information extraction, text mining, question answering, and more.
It plays a crucial role in many applications, including virtual assistants, chatbots, automated customer service systems, content analysis, and language translation tools.
