1. Text Classification: Categorizing text into predefined categories (e.g., spam detection).
2. Sentiment Analysis: Identifying the sentiment or emotion in a text (e.g., positive, negative, neutral).
3. 名前付き固有表現認識 (NER): Identifying and classifying entities like names, locations, and organizations.
4. Part-of-Speech Tagging: Determining the grammatical role of each word in a sentence (e.g., noun, verb).
5. Machine Translation: Translating text from one language to another (e.g., Google Translate).
6. Speech Recognition: Converting spoken language into text (e.g., voice-to-text applications).
7. Text Summarization: Creating a concise summary of a larger body of text.
8. Question Answering: Finding answers to questions posed in natural language (e.g., search engines).

Applications of NLP:

• Chatbots and Virtual Assistants (e.g., Siri, Alexa).
• Sentiment Analysis for social media monitoring.
