About the Course

Recent years have seen a dramatic growth of natural language text data, including web pages, news articles, scientific literature, emails, enterprise documents, and social media such as blog articles, forum posts, product reviews, and tweets. Text data are unique in that they are usually generated directly by humans rather than a computer system or sensors, and are thus especially valuable for discovering knowledge about people’s opinions and preferences, in addition to many other kinds of knowledge that we encode in text. This course will cover search engine technologies, which play an important role in any data mining applications involving text data for two reasons. First, while the raw data may be large for any particular problem, it is often a relatively small subset of the data that are relevant, and a search engine is an essential tool for quickly discovering a small subset of relevant text data in a large text collection. Second, search engines are needed to help analysts interpret any patterns discovered in the data by allowing them to examine the relevant original text data to make sense of any discovered pattern. You will learn the basic concepts, principles, and the major techniques in text retrieval, which is the underlying science of search engines....

Great course for those trying to understand how ro analyse and process text data. It has the right amount of tools to help you understand the basics of information retrieval and search engines.

A great overview of text retrieval methods. Good coverage of search engines. A longer course will cover search engine better (remember this is a 6 weeker)

Very well mounted course.

For the majority of the topics explained, focused on techniques, not jut on theory.

Good suplemental lectures listed.

This is not a class I would normally pursue. I took it as part of the "Data Mining" certification. That being said, this class was wonderful. I learned the basics of text retrieval and search engines. I went from knowing nothing, to having a working sense of how search engine algorithms work. It was a challenging course for me, but very much worth the time and effort I put into it. It was like pulling back the curtain on the code behind Google, Netflix, and Amazon searches, and that has made me think of the world in a different way. I am now a human happily collaborating with machine learning systems. Thank you!!

Interesting content

However the prof/instructor should practice not pausing so much when explaining the concepts/contents

Sir is Amazing. Reviews saying this course lacks practicals are true. Fact is, you will be able to implement them on your own, as sir explained concepts pretty well. This is by far one of the best courses on coursera, comparable to Mr. Ng's course on ML and DL
