Natural Language Processing (NLP) is a field at the intersection of computer science, artificial intelligence (AI), and linguistics. It focuses on the interaction between computers and humans through natural language. The objective of NLP is to enable computers to understand, interpret, and generate human language in a valuable way. By processing and analyzing large amounts of natural language data, NLP systems can perform a variety of tasks, such as:
1. Translation: Translating text from one language to another.

3. Speech Recognition: Converting spoken language into text.
4. Chatbots and Virtual Assistants: Engaging in conversation with users to answer questions or assist with tasks.
5. Text Summarization: Creating concise summaries of long documents or articles.
6. Named Entity Recognition (NER): Identifying and classifying named entities mentioned in text into predefined categories such as the names of persons, organizations, locations, expressions of times, quantities, monetary values, percentages, etc.
7. Part-of-Speech Tagging: Identifying words in text as nouns, verbs, adjectives, etc.
8. Machine Translation: Automatically translating text from one language to another.
