Lecture 8 Semantic Analysis - part 1
04:52

In this video you will learn about semantic analysis in text. You will be introduced to WordNet and learn about its use in enriching text analysis applications.

Lecture 9 Semantic Analysis - part 2
09:20

In this video you will learn about numerical vector representation of words (word embeddings). You will learn how this representation can be used to estimate semantic similarity or relatedness between words.

Lecture 10 Demo: Regular Expressions (RegExr)
10:45

In this video you will learn how www.regexr.com website can be used to find regular expressions that are shared by the community. It shows you also how to test your regular expressions live.

Lecture 11 Demo: Pre-processing (Stanford NLP)
04:13

In this video you will learn about the Standford NLP framework that can be used for text processing applications. The demo shows you how the framework can be used to extract part-of-speech tags and name entities from a text.

Lecture 12 Demo: Numerical Vector Representation of Words (GLOVE)
04:44

In this video you will learn about GloVe: a tool that lets you generate word embeddings. You will see how word embeddings can be used to estimate semantic similarity between words.

A very informative course I ever came across. It can definitely help me solve many day-to-day problems, and enables to do text analysis, clustering, classification in professional settings and much more. It is a great experience to learn from a founder of a successful Artificial intelligence startup with fifteen years. It is easy to learn artificial intelligence from a practical perspective, AI techniques, and its basics, and open-source frameworks to build AI applications. The course provides value for the time and money invested in learning it. The video learning is a new experience for me and able to grasp.

So far it has been excellent. So obvious! This is an intermediate foundation to marketing analytics, but the techniques presented here are indeed what you want to have.

This is one of the best classes I have ever taken. It is a delight, and quite comprehensive. I would usually put in 2-3 hours per week. The questions are demanding but good.

You will learn much more than using just analytics alone. You learn how to ask appropriate questions and how to put together your analytics results to the C-suite or whoever asked for it. I definitely recommend this to anybody- novices and professional business/data analysts. I got a lot out of this course.
