Study Notes
Natural Language Processing (NLP)
Definition
- A subfield of artificial intelligence (AI) that deals with the interaction between computers and humans in natural language
- Enables computers to understand, interpret, and generate human language
Key Concepts
- Tokenization: breaking down text into individual words or tokens
- Part-of-Speech (POS) Tagging: identifying the grammatical category of each word (e.g. noun, verb, adjective)
- Named Entity Recognition (NER): identifying named entities in text (e.g. people, places, organizations)
- Sentiment Analysis: determining the emotional tone or attitude behind a piece of text
NLP Techniques
- Rule-Based Approach: using pre-defined rules to analyze language
- Machine Learning Approach: using machine learning algorithms to learn from data and improve language analysis
- Deep Learning Approach: using deep learning algorithms, such as recurrent neural networks (RNNs) and convolutional neural networks (CNNs), to analyze language
NLP Applications
- Text Classification: classifying text into categories (e.g. spam vs. non-spam emails)
- Language Translation: translating text from one language to another
- Speech Recognition: recognizing spoken language and transcribing it into text
- Chatbots: using NLP to generate responses to user input
Challenges in NLP
- Ambiguity: words or phrases with multiple meanings
- Contextual Understanding: understanding the context in which language is being used
- Sarcasm and Irony: detecting and interpreting sarcastic or ironic language
- Linguistic and Cultural Variations: dealing with variations in language and cultural differences
