강좌 소개

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....

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.

A good start for the NLP aspirants ! But there are some problems need to be addressed. Such as, some quiz problems are given before they've been discussed. Also, I personally felt a bit problem in understanding the English accent of the Professor. Otherwise, a great course, learnt a lot of things !

Well taught course, although certain topics seemed rushed while others had a long time spent on them. The quizzes were completely messed up though (although I decided not to do the optional programming assignments, based on the discussion forums those have a lot of problems too).

this is a best course if you have interest in information retrieval subject. this course helps me to best understand the concepts of text retrieval. although the field has evolved so much after this course but this course is best for beginners in this field.

For understanding evaluation of search ranking algorithms, and picking up the ideas behind Learning To Rank, this course is great. The only glitch is that some of the quiz questions ask about material from weeks not yet covered!

The videos could not be too longer than they actually are. If this change, could be done, the student or user could have more time to dig into the assignments problems and even read more textbooks related to the main topic.

I have learned a lot of concepts through this course, but at a shallow level. It is a great introduction course to IR. It can be improved by adding more programming tasks for hands-on exercise

I will keep the last star for not using a more cutting edge programming language, e.g. python. MeTa is not really helpful in the business world and that discounts the value of this course.

I found that there were a lot of mathematical function in this course. I need to see the examples of how are those functions applied in the real programming which support the business.

I'd appreciate Prof.Zhai's lesson design with robust framework. BUT I really can not accept that the mistake that homework putted in wrong week and STILL NOT FIXED AFTER TWO YEARS!

This is course provide me a detailed overview of the search engine and some new concepts that I am not aware of . I think now I understand text retrieval techniques

Some mistakes in subtitle. and it is better to break down the long videos into smaller sections, illustrate the concepts with more graphs,picture and animation.

The explanation is detailed and clear. But the missing star is because I hoped the course would have programming assignments using popular language as python.

Cheng is a very good teacher. I'm amazed at how clearly he can teach complex topics. All topics are covered in the book "Text Data Management and Analysis".

This course goes through the basics of text retrieval systems with an appropriate speed. However, the contents are quite out-dated for 2019.

Decent course, and I really wanted to do the programming assignments, but I wasn't able to because the packages were unusable :(

Need indetail inputs on algorithm usage and correct MeTA assignments with working scripts. That makes learning a complete curve.

Good theoretical course. Some exercises need to be fixed, as they count for approval and are misplaced.

More programming assignments would have helped understanding the topics covered in the course better.

Great at theory and concept explanation... but just few examples and zero programming applications.

this course has a lot of ideas but I think these principles need some code for implementing

very great course but , the programing language was C++ intead of Python :(
