Study Notes

Natural Language Processing (NLP)

NLP is a field of research in computer science that combines AI and Deep Learning to enable computers to understand and process human language.
The goal of NLP is to enable computers to interact effectively with humans through natural language.

Natural Language Understanding (NLU) and Natural Language Generation (NLG)

NLU deals with understanding the meaning of human language, usually expressed as text.
NLG generates text, allowing computers to "talk" to humans through natural language.

Examples of NLP in Action

Chatbots use NLU to understand questions and NLG to generate responses.
Example: a chatbot answering the question "do penguins fly?" requires NLU to understand the question and NLG to generate a response.

Common Tasks in NLP

Language Translation: translating from one language to another (e.g., Google Translate).
Speech Recognition: converting voice data into text.
Text Summarization: summarizing text from literature.
Sentiment Analysis: extracting subjective qualities like attitudes, emotions, and sarcasm from text.

Challenges in NLP

Ambiguity: human language can be ambiguous at different levels (word, sentence, etc.).
Use of common sense: humans do not learn language by observing an endless stream of text, making it difficult for computers to understand language.
Figurative language: phrases with non-literal meanings pose a challenge for language understanding algorithms.

Text Pre-processing for NLP Applications

Preprocessing is a crucial step in NLP that cleans, harmonizes, and prepares text for further processing.
Agenda for text preprocessing includes:
- Text cleaning/harmonization/reduction of fluctuations
- Text normalization
- Segmentation
- Stop words
- Stemming & Lemmatization

Tokenization

Tokenization is the process of breaking down text into smaller chunks, called tokens, such as words, phrases, symbols, or other meaningful elements.
