Karthik Balakrishnan (5/5): Great introductory course to NLP! Despite having a background in Machine Learning besides being a developer, NLP is something I had never delved into. This course albeit short, it a good introduction to concepts in this space. As the instructor says, intuition is developed in hindsight, and not getting your hands dirty leads to weak fundamentals. I’m on my way to the “advanced” course with Deep Learning next. Just one suggestion – watch the Appendix lectures before starting on this course. The instructor provides several vital tips!
- Patrick Olson (4/5): This is an excellent course to get me started on NLP.
- Andrei Yevseyev (5/5): The best part is that I implemented an end to end system of NLP tasks
- Adnan Ali (5/5): This is the best way to learn applications and basics of NLP.
- Sowjanya (5/5): Explanation is very good and the design / order of content is excellent
- Marina Pliusnina (2/5): The worst course I ve taken in the last 2 years.
- Marina Pliusnina (2/5): No logic in the structure of the course and in the material itself, jumping from difficult topics to first-to-learn ones.
- Eugen Klein (2/5): The author decided not to dwell on theory behind the ML algorithms, but instead to concentrate on NLP/ NLP applications.
- Eugen Klein (2/5): Explanations are superficial and a lot of times incorrect or just plain useless.

Data Science: Natural Language Processing (NLP) in Python: FAQs
Ques. Why is NLP needed?
Ans. NLP is required to scale language-related tasks; natural language processing enables computers to converse with people in their own language. For instance, NLP enables computers to read text, hear a voice, analyze it, gauge sentiment, and identify the key points.
Ques. Can Python be used for NLP?
Ans. Making natural human language accessible to computer programs is the goal of the field of natural language processing (NLP). You can use the Python library NLTK, or Natural Language Toolkit, for NLP. A large portion of the data that you might be examining is unstructured and contains text that can be read by humans.
Ques. What are the applications of NLP?
Ans. NLP is used in a variety of tasks such as Email filters, smart assistants, predictive texts, search results, text analytics, etc.
