[MUSIC] Hello everyone, I am Seonmin Park. Welcome to my Big Data and Language course. I am Seonmin Park, at Korea Advanced Institute of Science and Technology. Today, I want to introduce my course, Big Data and Language. So are you ready? Let's get started. The fist one I want to introduce the Course Overview. There are five goals for this course. The first one is why and how big data is used for language analysis. And the second one is different characteristics of spoken and written data and the concept of linguistic registers. If you haven't heard the register, that term yet, don't worry about it, I'm going to explain more later. And the third objective and third goal is basic linguistic knowledge for language analysis, such as part of speech or collocations. Again, if you haven't heard about the part of speech, POS, or collocations, do not worry about it, I'm going to introduce one by one later. And the fourth goal is tools to extract meaningful information from the text data. So I'm going to introduce various types of tools so you can use the tools for your data analysis. And the fifth, the final goal is I want to introduce the recent technology in the natural language processing field. There are five big goals, so I want to introduce one by one more detail. The first one is why and how big data is used for language analysis. Have you ever heard about the Fourth Industrial Revolution? Or have you ever heard about any Industrial Revolution? There are four different types. So I will introduce in this course, what's the relationship between this industrial revolution and also the big data for language analysis. And the second goal is to understand different characteristics of the spoken and written data and the concept of linguistic registers. So think about that when you write an email to your boss, what kind of language or what kind of vocabulary do you use? Is that language exactly same as what you use for your daily conversation to your family or your friends? Maybe they are different. Now you might notice that the language in your daily life, depending on the situation you may use different types of language. So we will learn about that more in this part and also including the linguistic registers. And the third objective and third goal is basic linguistic knowledge for language analysis. So if you are not majoring in linguistics or you do not have the background of linguistics, do not worry about it. If you are still interested in using big data to analyse the linguistic features, I will introduce the new or basic concept for your linguistic analysis in this course. And the fourth goal in introducing and understanding the tools to extract the meaningful information from the text data. You may have data already, but you may not know how you can use that data or what kind of features that you can find from the data that you already have. So I will introduce different types of tools, which is already existing. And also you can use it for free, very easily if you already have the computer or any access to the Internet. So I'm going to introduce these tools in this course. And the final goal, you maybe interested in language processing, natural language processing. So I want to cover and explain about the recent technology in the natural language processing field. Maybe that will be another course, however, still if you're interested in, you will get the trend. All right, so far we've talked about the goals of this course, then who would want to take this course? This course is for students who desire to understand authentic text data. Authentic text data means practical and realistic data you can find in your daily life or your daily conversation, daily email, like anything around you. And also this course is good for those students who are curious about how to use computers to analyze features of text data. And also this course is meaningful and useful for students who want to learn scientific approaches to analyze linguistic features. And also the students who are interested in artificial intelligence in order to understand the human's natural language. I believe this course will be helpful. This course will be divided into two major parts Big Data and Language I and Big Data and Language II. Then, what are the differences? In the Big Data and Language I, we will focus in on understanding basic linguistic knowledge for language analysis. In the second course, you will have a chance to comprehend the existing big data. And also you will have a chance to enhance practical skills of analyzing text data. And finally, you will conduct your own project, I will give you some feedback and your peer also will give you some feedback. So you will finally, complete your project more meaningfully and insightfully. All right, so now let me introduce the activities in this course. There are majorly four different parts. The first one is, I will give you the short lectures, the series of lectures every week. And also after the lectures, you need to take a short quiz, that will be like multiple choice quiz in order to check your understanding of this course. And the third one is I will give you some tasks so you can not only just check in your understanding, you can apply and implement your understanding and knowledge to the real data. And the last one is, even though this one is online course, I encourage you to participate in discussion. Okay, so today I cover the introducing this course. And next time I will introduce the 4th Industrial Revolution, Big Data and Language. Thank you.
