Academic Papers on NLP
From one of my reddit comments...
So the best introduction to NLP is this video by Irving Kirsch. Here are the slides.
But if you want to really research NLP, you should get into the original papers. This is great fun and relatively easy these days. If you have Zotero and the Scihub plugin for Zotero, you can plug in any DOI link and it'll come up. You may have additional papers that you want to pull from citations; I use Semantic Scholar to turn citations into DOI links that I can get Zotero to pull.
So here's my research on NLP (if you copy and paste the URLs into https://sci-hub.hkvisa.net/ they'll give you the PDFs):
Predicate Matching in NLP
The Eyes Don’t Have It: Lie Detection and Neuro-Linguistic Programming
Research findings on neurolinguistic programming: Nonsupportive data or an untestable theory?
Mental imagery as revealed by eye movements and spoken predicates: A test of neurolinguistic programming
Neuro-linguistic programming treatment for anxiety: Magic or myth?
Double hypnotic induction: An initial empirical test
Neurolinguistic programming: a systematic review of the effects on health outcomes
There's also the papers that Michael Heap did:
Neurolinguistic Programming - An Interim Verdict
Neurolinguistic Programming: What is the Evidence?
Neurolinguistic Programming: A British Perspective
The Validity of Some Early Claims of Neurolinguistic Programming
Also recommended is @ellaenchanting's overview and Wordweaver's discussion on what NLP repackaged.

Today, I want to dive into the fascinating world of Natural Language Processing, or NLP. 🌐✨
What is NLP?
Natural Language Processing is a field of artificial intelligence (AI) that focuses on the interaction between computers and humans through natural language. The ultimate goal of NLP is to enable computers to understand, interpret, and respond to human language in a way that is both meaningful and useful.
Why is NLP Important?
NLP is crucial because it helps bridge the gap between human communication and computer understanding. With the vast amount of unstructured data generated daily (like emails, social media posts, and documents), NLP allows for the extraction of meaningful information and insights.
Key Components of NLP:
Tokenization: Breaking down text into smaller units like words or phrases.
Part-of-Speech Tagging: Identifying the grammatical components of each token (e.g., nouns, verbs).
Named Entity Recognition (NER): Detecting and classifying entities like names, dates, and locations.
Sentiment Analysis: Determining the sentiment or emotion expressed in a piece of text.
Machine Translation: Automatically translating text from one language to another.
Speech Recognition: Converting spoken language into text.
Applications of NLP:
Chatbots and Virtual Assistants: Siri, Alexa, and Google Assistant use NLP to understand and respond to user queries.
Text Analytics: Analyzing customer feedback, reviews, and social media posts to gauge public sentiment.
Language Translation: Services like Google Translate help break down language barriers.
Content Generation: Tools that help in drafting emails, articles, and even code.
Challenges in NLP:
Ambiguity: Words and sentences can have multiple meanings.
Context Understanding: Grasping the context in which something is said or written.
Sarcasm and Irony: Detecting nuanced language use can be tough.
Future of NLP:
As technology advances, NLP will become even more sophisticated, improving our interactions with machines and making information retrieval and communication more seamless.
I hope this gives you a clearer picture of what NLP is and why it's such an exciting field! Feel free to ask any questions or share your thoughts below. 🌟
