About the Course

Recent years have seen a dramatic growth of natural language text data, including web pages, news articles, scientific literature, emails, enterprise documents, and social media such as blog articles, forum posts, product reviews, and tweets. Text data are unique in that they are usually generated directly by humans rather than a computer system or sensors, and are thus especially valuable for discovering knowledge about people’s opinions and preferences, in addition to many other kinds of knowledge that we encode in text. This course will cover search engine technologies, which play an important role in any data mining applications involving text data for two reasons. First, while the raw data may be large for any particular problem, it is often a relatively small subset of the data that are relevant, and a search engine is an essential tool for quickly discovering a small subset of relevant text data in a large text collection. Second, search engines are needed to help analysts interpret any patterns discovered in the data by allowing them to examine the relevant original text data to make sense of any discovered pattern. You will learn the basic concepts, principles, and the major techniques in text retrieval, which is the underlying science of search engines....

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 Tools provided for the assignments are outdated.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.
