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.
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.

Good class, knowledge learned. Below are some problems I personally encountered.
* there are almost no explanations of the quiz/exam answers and some questions in quizzes did not match the course progress. However, before the final quiz, there is a small quiz in advance, you can do small quizzes for unlimited times and it resembles the final quizzes. Maybe the author designed this on purpose for the users to learn by trial and error?
Another way is finish courses of the next week, and then come back to finish the quiz of the previous week.
* some concepts require previous knowledge, otherwise you'll have to Google during the class.
* It might take some time to get used to the speaker's accent for non-English speakers.
* suggest that the instructor could use a touch screen or stylus to illustrate on screen.
* The honor missions are out-dated and requires a lot of de-bugging.

The course provides a nice framework for the learners. The instructor is very knowledgeable and has covered a very wide range of information regarding text retrieval tasks.
Unfortunately, the lab design is not very good - a bit outdated, if not broken at all. I gave 4 stars because I really hope the course can improve that part.
Tips: The quiz is not necessarily easy, but easy to pass, if that's what you care about. However, the nitty-gritty of this course is better comprehended by implementing it on some tasks. That said, find some guide project and try it on, projects like toy recommendation system, toy search engine, etc.

The class content layout is excellent, it gives an overall picture about text retrieve and search engine, also point out the direction of further learning. Professor Zhai teaches excellent too. In lecture, those simple examples help understanding the algorithm very well.
I just hope Professor Zhai can provide more wide or deep class on such topic.
The only drawback is the program assignment is not well maintained. Almost no staff answer questions.

I'm withholding one star mainly because the MeTA programming assignments need to be rewritten. MeTA has undergone a major revision change since this course was created and much of the code provided by the instructors no longer works/compiles against MeTA. Judging from the forum discussions, many students are struggling to get the coding assignments working. Otherwise the lectures and the reading materials were good.

Excellent lecture material with many very interesting concepts. Instructor clearly talks about topics and why they're important. -1 star due to: content being on quizzes before being covered in lecture, compilation errors in the programming assignments, errors in submitting programming assignments, and lack of instructor support/feedback on the discussion forms.

The course is interesting and you can learn a lot. The professor is very knowledgeable in the area of search engines. However the course goes very early into mathematical details without too much context. The programming assignments are great and I would focus more on them as they really show you how the engine works.
