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)

Some mistakes in subtitle. and it is better to break down the long videos into smaller sections, illustrate the concepts with more graphs,picture and animation.

The explanation is detailed and clear. But the missing star is because I hoped the course would have programming assignments using popular language as python.

Cheng is a very good teacher. I'm amazed at how clearly he can teach complex topics. All topics are covered in the book "Text Data Management and Analysis".

This course goes through the basics of text retrieval systems with an appropriate speed. However, the contents are quite out-dated for 2019.

Decent course, and I really wanted to do the programming assignments, but I wasn't able to because the packages were unusable :(

Need indetail inputs on algorithm usage and correct MeTA assignments with working scripts. That makes learning a complete curve.

Good theoretical course. Some exercises need to be fixed, as they count for approval and are misplaced.

More programming assignments would have helped understanding the topics covered in the course better.

Great at theory and concept explanation... but just few examples and zero programming applications.

this course has a lot of ideas but I think these principles need some code for implementing

Interesting and Informative module. The only setback was overlapping of weekly content

Some quizes were from different weeks. Forum questions are often left unsolved.
