Poor ability from lecturer to explain key concepts.

the course is ok, should be more technical though.

Very exciting topic, but not so exciting course.

Its ok but was the worst of the specialization

Good contents, but not very clearly explained.

programming assignments are too technical

Topics like LDA need better explanations.

The assignments were a little complex

A lot of issues with the auto graders

Last week is not properly thought

Good for basic understanding only

More Hands on is required on it.

Assignments were too difficult.

Week 4 was not sufficient

Is difficult, but good.

I like the lecturer.

Bad autograder

good training

nice

bad

I have major qualms with this course. So far in the specialization, this course is certainly the worst. *The autograder is terrible, having had serious, known issues for 8+ months at the time of this review.*The course content is incorrect, teaching learners the incorrect way to calculate roc_auc_score. *The course blows through certain topics, like Part-of-Speech tagging & Parsing sentence structure, leaving learners like myself without a good overview. I don't even have a good set of links to learn more. I can run a few commands and understand why it might be important, but I have no idea how to use it in practice. *Unlike other courses in the specialization, this one doesn't have good links to interesting academic papers or real world applications.*Unlike other courses, every week does NOT include a weekly Juptyer notebook.Here's a simple solution - give Uwe, an excellent and active Mentor, the permissions to fix this broken course. On the plus side: the instructor is ok, the topic is interesting, and this course really only feels terrible relative to the excellent courses in this specialization. I can still hardily recommend the specialization...

Unfortunately, this is one of the worst courses I have ever taken. The later lectures did not have much of a content, and assignments were very badly described and evaluated. The latter is in general one of the weaknesses of this specialisation, but this course made me particularly frustrated. There did not seem to be any moderator answering students' questions which at least in one case led to a big confusion as one of the students wrote that his wrongly (as I got it later) written code worked ok which led to a long and misleading discussion between students how to interpret and tweak the assignment to pass the grader, which made me waste a lot of time. Would be great if wrong interpretations and statements written by students are timely deleted, corrected or flagged.

In summary, the assignments' descriptions and grading system do need to be improved (for example, one can introduce some hints such as 'the grader expected this output for this input0, but the student solution returned this' as it is done in a few other courses on Coursera).

This course provides an interesting introduction to natural language processing in Python. The lessons are well thought, they are brief and to the point. It is very exciting to discover all the tools at our disposal to work in this field. The main problem of the course, as it seems to happen in the whole specialization, is resolving the assignments. Usually, they are poorly described, which forces the student to review the forums to understand what they are asked to do. In addition, the part of the tasks related to the course's topic is usually very simple, sometimes trivial. On the other hand, several hours may be required to generate the specific data structures required by the autograder an dealing with weird issues, that is, much more time is devoted to deal with autograder problems than learning about the subject. I do not understand why this problem keeps repeating one course after another.

Text mining and NLP were areas of this specialization that I was particularly interested in learning more about and I was mostly disappointed by the course. The staff's refusal to update to the latest versions of software is frustrating because being successful in this industry means staying up with the latest trends. I recall at least one lesson that required Python 2.x, which as of 2020 is no longer supported.

While it is completely understandable that assignments include some concepts that were not taught in the lectures; this course had way too many self-learning concepts in the assignments many of which were covered in the very next lesson.

On a good note, the instructor is very passionate about the topic and covers a lot of material. The course mentors are very knowledgeable and helpful and there is no way I would have been able to pass the course if it wasn't for them.
