Natural Language Processing (NLP) is a subfield of Artificial Intelligence that focuses on enabling machines to understand, interpret, and respond to human language. It powers a wide range of applications—from virtual assistants and chatbots to machine translation and automated summarization.

The primary types of NLP include:

1. Speech Recognition – Converting spoken language into text.
2. Natural Language Understanding (NLU) – Interpreting and deriving meaning from language input.
3. Natural Language Generation (NLG) – Producing human-like language responses.
4. Machine Translation – Automatically translating text from one language to another.

The standard NLP pipeline involves:

1. Text Preprocessing – Cleaning and structuring input data.
2. Lexical Analysis – Analyzing words and their structure.
3. Syntactic Analysis – Parsing grammar and sentence structure.
4. Semantic Analysis – Extracting the intended meaning of words or phrases.
5. Pragmatic Analysis – Understanding language within context.

The seven linguistic levels that NLP systems aim to model include:

1. Phonology – Study of sound patterns.
2. Morphology – Structure of words.
3. Lexical Level – Vocabulary and word-level analysis.
4. Syntactic Level – Grammar and sentence construction.
5. Semantic Level – Meaning of individual words and phrases.
6. Discourse Level – Contextual meaning across sentences.
7. Pragmatic Level – Interpretation based on real-world knowledge and context.

This natural language processing online free course primarily uses Python due to its simplicity and widespread use in AI and NLP projects. Python’s libraries, like NLTK, spaCy, and Regex, are leveraged to demonstrate core concepts and implement real-world solutions.

No prior programming or technical background is required. The course is beginner-friendly and designed to introduce concepts step-by-step, making it suitable for learners from both technical and non-technical backgrounds.

While this is a self-paced course, learners can benefit from discussion forums, peer support, and community Q&A spaces. These resources help clarify doubts, share learning experiences, and build a support network for NLP enthusiasts.

Yes, learners get lifetime access to all course content. You can revisit tutorials, exercises, and reference material anytime—whether to refresh your memory or apply NLP in future projects.
