Study Notes

Natural Language Processing (NLP)

Natural languages differ from artificial and constructed languages, such as computer programming languages.
Natural languages also differ from non-human communication systems in nature, such as whale and other marine mammal vocalizations or honey bees' waggle dance.
NLP aims to transform free-form text into structured data, and vice versa.
Most NLP techniques rely on machine learning to derive meaning from human languages.
NLP has successful implementations in search engines like Google, social websites like Facebook’s news feeds, speech engines like Apple Siri, and spam filters.

Challenges in NLP

There are hundreds of natural languages, each with different syntax rules.
Words can be ambiguous, with their meaning dependent on the context.

NLP Applications

Word embeddings and topic modeling are key applications in NLP.
MALLET is a Java-based library used for classification, sequence tagging, and topic modeling.

Python NLP Libraries

Python offers several NLP libraries, including:
- Natural Language Toolkit (NLTK)
- TextBlob
- CoreNLP
- Gensim
- spaCy
- polyglot
- scikit–learn
- Pattern

Natural Language Toolkit (NLTK)

NLTK is the most widely used NLP library in Python.
