Very clear, make me have a basic understanding of data mining and data retrieval. Thanks very much.

Overall, a very good introductory course. It is doorway to explore TR systems further and this course gives you a good understanding of lay of the Information Retrieval land.

Couple of tests during the entire course need you to read ahead the next week's course and even though the issue has been reported more than 2 years ago, as of this writing, they have not been fixed

Great insights in this course... I learned so much!!

Very good course for someone who wants to understand how text retrieval works.

very good for learners

thanks

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

Excellent ! Well organized, presented with aptitude to detail. Definitely will recommend and take further units in this specialization.

Thanks Prof

Excellent Introduction to Text Retrieval and Search Engines technologies.

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

Good survey of techniques

The videos could not be too longer than they actually are. If this change, could be done, the student or user could have more time to dig into the assignments problems and even read more textbooks related to the main topic.

For understanding evaluation of search ranking algorithms, and picking up the ideas behind Learning To Rank, this course is great. The only glitch is that some of the quiz questions ask about material from weeks not yet covered!

I have learned a lot of concepts through this course, but at a shallow level. It is a great introduction course to IR. It can be improved by adding more programming tasks for hands-on exercise

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.

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

Was interesting

I found that there were a lot of mathematical function in this course. I need to see the examples of how are those functions applied in the real programming which support the business.

This course is really great but the programming assignments need to be updated.

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.

Good with concepts.

Some problems about program assignments and quiz.

I wish it was a bit more concrete course with practical examples.

very great course but , the programing language was C++ intead of Python :(

Very Informative, hope to give more examples
