NLP and its Applications
01What is NLP?
NLP stands for Natural Language Processing. It is a subfield of AI. It deals the interaction between humans and computers in natural language. It uses computational techniques to process and analyze the data.
02Applications
1. Question Answering - It refers to the ability of AI systems, such as Siri or Alexa, to interpret a user's query and provide a direct, relevant reply rather than just displaying a list of search results.
2. Spam Detection - Algorithms that identify specific keywords (like "danger") in emails to automatically filter messages into spam folders.
3. Machine Translation - Tools, such as those used in Chrome, that convert text from one language to another.
4. Speech Recognition - Technology that converts spoken speech into text, such as the automatic CC (closed captioning) feature on YouTube.
5. Chatbots - Conversational interfaces often found as pop-ups on websites to assist with user interactions.
6. Sentiment Analysis - A process that analyzes text to determine the emotional state or mood of the writer, such as detecting if someone is happy based on their use of words like "enjoying."
