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 introductory course. It has opened my eyes to new challenges that face information retrieval. DON"T TAKE THIS COURSE IF YOU WANT TO LEARN elasticsearch.

This course has some good content, but it seems like it was abandoned. It was made a couple of years ago and I didn't perceive updates. Only has 2 programming assignments and they are optional and they use C++ and a very awkward framework. There are many problems while doing these assignments (lack of information) and there were no support at all. The discussion forums are almost inexistent.

Professor ChengXiang Zhai manages to point out the critical topics in this area in a very efficient, effective and realiable way. I will take this course twice. Thank you, Coursera and University of Illinois, for this opportunity!
