This course will introduce the learner to text mining and text manipulation basics. The course begins with an understanding of how text is handled by python, the structure of text both to the machine and to humans, and an overview of the nltk framework for manipulating text. The second week focuses on common manipulation needs, including regular expressions (searching for text), cleaning text, and preparing text for use by machine learning processes. The third week will apply basic natural language processing methods to text, and demonstrate how text classification is accomplished. The final week will explore more advanced methods for detecting the topics in documents and grouping them by similarity (topic modelling). This course should be taken after: Introduction to Data Science in Python, Applied Plotting, Charting & Data Representation in Python, and Applied Machine Learning in Python. The mission of the University of Michigan is to serve the people of Michigan and the world through preeminence in creating, communicating, preserving and applying knowledge, art, and academic values, and in developing leaders and citizens who will challenge the present and enrich the future.

    Excellent course. Teaches useful knowledge and skills and does it with a very good teaching staff.

    Autograder is a disadvantage that sometimes can take many hours to figure out. Also, this course was a let down compared to the previous in the specialization. I wish there were more examples.

    I have taken and passed all the first four courses in this specialization, and very much liked the first three courses. But the quality of this course on text mining is far below the average level of the first three. Go find some other courses if you want to learn text mining with Python. There are too many areas of flaws in this course. I am only highlighting the top 5 below: 1. lacks good connection throughout the course content. This problem exists almost everywhere, both from slide to slide within a video and from video to video. Many times you would have questions in your head like “why is he talking about this?” or “what is this?” 2. use example just for the purpose of showing examples. Don’t really explain the point it is supposed to explain. In many times the examples do not provide clarity, but raise more confusion instead. 3. assignment tasks either too simple, or remotely related to what is introduced in the course. The worst case is assignment in week 4, where the assignment is so poorly constructed. You have to spent days to figure out the right answer. They call it “debug”, but there is nothing wrong with my code. I would say it is more of a process to “try to figure out what the instructor is asking for”. 4. talks too much about the theoretical things, not very good introduction of using python. Even when python code is demonstrated, it is almost always in a very abstract way. This is significantly different from the first three courses, and very annoying. You would need to spend about the same amount of time googling how the packages work as I have never took the course. 5. Repetition of content already introduced in previous courses, i.e., machine learning basics.

    The course wasn’t totally bad but it definitely wasn’t as good as the first three. I felt I was thrown in with insufficient tools to cope with the assignments. Relying on the internet is important but in these cases, you have to rely on it quite heavily. On assignments 1 and 3 in particular, Upon final submitting, I felt I didn’t learn much at all. Specifically with regexs, I feel extremely insecure with my regex skills and that is an understatement. I don’t think that is something that should happen after a text mining course. The following remark *isn’t* a crucial one: For a non native English speaker understanding the language could sometimes pose an obstacle. Now, decoding the lecturer’s accent is yet another obstacle on top of the former. Lecturer with an American accent will obviously be the best choice.

    Confusing explanations of NLP concepts. Inadequate explanations of how to use the Python packages to solve the assignment questions. I’m writing this review half way through the Applied Social Networks Analysis course which is excellent and pitched just right. The contrast between the 2 courses couldn’t be greater.

    Compared to other courses, there’s a disconnect between what’s covered in the lecture and what’s needed to complete the assignments; the lectures at times have a more theoretical flavor. For a course with “applied” in the name, that’s a more significant mistake.

    A lot of exercises have unclear instructions (see discussion forums). The exercise on topic modeling especially was a waste of time, you’re not really learning anything by running these small pre frabricated scripts. In general the exercises were extremely shallow and did not require any creativity or actual problem solving, in contrast to some of the earlier courses in this Specialization.

    This course contents was good, but the assessment was really bad. You guys need to fix the autograder issues ASAP and I feel the instructor was not taking as much care as others to set the autograder propertly. Lot of time was unnecessarily wasted I would say as the instructions could have been better. Very disappointed with the assessment. Course is very useful and valuable.

    This course compared with the others in this specialization, is not as well organized. You might have to spend lots of time working on the assignments by yourself (i.e. you cannot find related guidance in the course materials); There is less helpful online information, compared to course 1 3 in this specialization, either so it is a little painful to do these assignments. However, the tools and the theories behind them are useful and powerful. If you are really interested in text mining, you will benefit a lot! The instructor is passionate and humorous.

    I found this course the least valuable of the courses in the specialisation so far. The video content wasn’t quite as slick/informative, the assignments not quite as useful or well worded, making them ambiguous in a few places and generally it just wasn’t quite as good. Not terrible, but just not quite up to the high standards of the other courses so far.
