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.
