Introduction to NLP and Text Mining
In this course you will be introduced to the essential techniques of natural language processing (NLP) and text mining with Python.
Overview
In this course you will be introduced to the essential techniques of natural language processing (NLP) and text mining with Python. The course will discuss how to apply unsupervised and supervised modeling techniques to text, and devote considerable attention to data preparation and data handling methods required to transform unstructured text into a form in which it can be mined.

Learning Outcomes
This course focuses on learning key concepts, tools and methodologies for natural language processing with an emphasis on hands-on learning through guided tutorials and real-world examples. You will learn how to:
- Process text data and strings, and perform pattern matching with regular expressions in Python
- Preprocess and wrangle noisy text data via stemming, lemmatization, tokenization, removal of stop-words and more
- Represent text data in structured and easy-to-consume formats for machine learning and text mining
- Represent text documents using features related to text word frequency, parts of speech and sentiment
- Represent text documents using vectorized features like bag-of-words, TF-IDF, and document similarity
- Use the concepts of information retrieval and document similarity (e.g. in applications like recommender systems)
- Perform unsupervised NLP using techniques like keyphrase extraction, topic modeling and text summarization
- Leverage pre-trained models for part-of-speech (POS) tagging and named entity recognition (NER)
- Develop supervised models to classify documents
Who Should Take This Course
Data scientists and aspiring data scientists who want to analyze text data and build models that use text data.

Prerequisites
Predictive Analytics 1 – Machine Learning Tools
- Skill: Intermediate, Advanced
- Credit Options: ACE, CAP, CEU
The Statistics.com courses have helped me a lot, pushing me to the limit and making me learn much more than I expected I could. The knowledge I gained I could immediately leverage in my job … then eventually led to landing a job in my dream company – Amazon.
Karolis Urbonas
This program has been a life and work game changer for me. Within 2 weeks of taking this class, I was able to produce far more than I ever had before.
Susan Kamp
The material covered in the Analytics for Data Science Certificate will be indispensable in my work. I can’t wait to take other courses. Great work!
Stephen McAllister
I learned more in the past 6 weeks than I did taking a full semester of statistics in college, and 10 weeks of statistics in graduate school. Seriously.
Amir Aminimanizani
This is the best online course I have ever taken. Very well prepared. Covers a lot of real-life problems. Good job, thank you very much!
Elena Rose
The more courses I take at Statistics.com, the more appreciation I have for the smart approach, quality of instructors, assistants, admin and program. Well done!
Leonardo Nagata
This course greatly benefited me because I am interested in working in AI. It has given me solid foundational knowledge…After completing this last course, I feel I have gained valuable skills that will enhance my employability in Data Science, opening up diverse career opportunities.
