This course is a pretty good resource for full-time graduates who are doing research in Natural Language Processing, but not for other people who want to learn in part-time some concrete skills to resolve specific text mining problems.
The course-style is heuristic-guiding based. Some questions are presented in lecturing or quiz, and answers are hardly found. So, some text books had better be specified.
Homework of this course is quiz-based, only one optional programming task. It's easy to pass the course, but it's hard to master its content. As an application science area, more practical assignments should be provided, as can help students learn better.
This is a 6-week open course teaching a complicated research area, Natural Language Processing, so most of its topic cannot be discussed in detail. However, this course could be designed and organized better.
