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.

Ok. It was a rerun and there wasn't much help in the Forum and there were too few exercises. But it was really interesting.

Interessant, but it wasn't organized too well. Some questions referred to topics which came in the next lesson

Heavily focused on formulas. I prefer courses which focus on basic concepts more.

This course covers text retrieval well. The topics are well chosen and the lectures are excellent.
However, there are small content issues that need to be addressed. This course has now been out for ~4 years, so they will likely never be addressed: 1) The smaller issue is that quizes are not written correctly to follow the lecture material. Various quiz questions come from material that's covered later in the course. 2) The larger issue is that the programming assignment is broken in many, many ways. In order to pass, you may need to read a large number of forum posts .. and hope that someone with your operating system and version has already solved the error. Further, some tasks even when completed correctly will not be accepted; it will be very frustrating trying to "trick" the online grader into accepting your correct answer.
If you want to learn the material and are prepared to deal with the problems that I mentioned, I would recommend this course.

The material is compelling and the lecturer is engaging, but the course is not well prepared. The assessments are not relevant to the material covered and there are no collateral materials (e.g., downloadable slides/handouts) available to assist in learning.

The presentation of the lectures is done quite poorly:There is a constant humming of the presenters computer on most of the videos. The examples given are all very specific and concepts are not explained themselves in detail.The quizzes are not very well adjusted to the presentations in that sometimes tiny details of mentioned information are asked and on the other hand non straight forward transfers from the lectures are expected.Also in one of the quizzes topics from the next week are asked and the problem has not been fixed since 5 months even though there are heavy complains in the forums.

The week 4 quiz has some questions from Week 5 material causing a low grade for my week 4 quiz. I've asked to have my week 4 grade dropped in the week 4 discussion fourm since it was based on a flawed quiz. Please read the forums and reply to everyone who had issues with the week 4 quiz and the honers project errors. No one seems to respond to these issues on the fourms except for other students agreeing that the week 4 quiz is flawed and that the honors section also has errors.

Very poor cooperation From the instructor. Tools provided for the assignments are outdated. Stops working very often. Haven’t provided any alternatives also.
The videos were too much lengthy. It was very difficult to keep concentration for that period of time.
Overall, i am extremely dissatisfied. I won't recommend this course at all.

Lectures are great. However, the assignments are almost impossible to do. They use a library that is no longer being maintained. It doesn't compile on modern Linux versions. Also the quizzes sometimes ask questions on material that isn't covered until the next lecture.

This course is only based on the theoretical side, and it is very hard to understand if you do not have a strong CS or math background. The professor also used abnormal verbal language to demonstrate his idea, I do not recommend this course.

The quiz contains questions of topics missing in the lecture of the same lesson. The presentation of the information has a lot of room for improvement. Hope the course continues to improve.

In Week 1 and 4 questions to pass the assignment are coming from one week later....
So the material provided every week to pass does not fit the assignment questions.
Should be improved.

This is not very informational whatsoever. After some sifting, I did not find this course to be useful. I would rather complete a formal course on the topic at the university itself.
