Hello everyone. Welcome to Big Data and Language. From now on, let's talk about the Fourth Industrial Revolution and Big Data, which means today we will focus on the background and history of big data. But first of all, have you ever heard about the Fourth Industrial Revolution? In 2016, World Economic Forum, it refers to the Fourth Industrial Revolution, which means evolving into a more intelligent society where everything is connected. So here is the key point, the more intelligent society and everything is connected. So let's look at one by one, which means let's go back to the First Industrial Revolution. The First Industrial Revolution is the transition to new manufacturing processes in Europe and the United States, which means it was the transfer from the hand production methods to machines. It was increasing use of steam power and the water power. So it was the rise of the mechanized factory system. The dominant industry was textile. Here is an example, according to Backert in 2014, in 1788, there were 50,000 spindles in Britain, rising to seven million over the next 30 years. So it was a dramatically increase. The share of value added by the cotton textile industry in Britain was 22.4 percent in 1831. So it was a really big market. So the First Industrial Revolution led to an unprecedented rise in the rate of population growth and urbanization. So now, let's move to the Second Industrial Revolution. The Second Industrial Revolution was technological revolution, which means a phase of rapid industrialization. Constable 2003, mentioned that electrification was called the most important engineering achievement of the 20th century by the National Academy of Engineering. The dominant industry was telegraph and railroad networks, and also gas and water supply, and sewage systems. So the Second Industrial Revolution was led to unprecedented movement of people and ideas. So by 19th century, 40 percent of the US population lived in cities compared to the just six percent in 18th century. So compared to 19th and 18th century from six percent to 40 percent. So again dramatically increased. So it was culminated in a new wave of globalization as well. So we'll briefly go over the Second Industrial Revolution. Now, let's move to the Third Industrial Revolution. The Third Industrial Revolution is the digital revolution. It brought semiconductors, mainframe computing, personal computing, and the Internet- the digital revolution. It was the transfer from analog to digital technologies. It was an old television you used to tune in with the antenna being replaced by an Internet-connected tablet. So it was the representative example like the TV usage and or TV change to TV system changes. So the Third Industrial Revolution began to automate production and take supply chains global. So far we've talked about and gone over the First, Second, and Third Industrial Revolution. So now let's move to the Fourth Industrial Revolution. The Fourth Industrial Revolution is based on the second revolution, which means including the intelligence and information. So let's look at more detail and compare the Third Industrial Revolution and the Fourth Industrial Revolution. In the Third Industrial Revolution, we can say that the Third Industrial Revolution was the analog era, communication era, digital era, or and Internet era. In contrast, the Fourth Industrial Revolution is more like the Data era, and AI era, and also Artificial Creation era as well. So which means the data here in the Fourth Industrial Revolution is pretty important source for any kind of technology. So now let's look at how the big data is used for what kind of technology. So for example, Cloud computing is used based on big data. Also, the smartphones are used based on big data as well. For example, if you are the iPhone users, then maybe you can talk to Siri and ask the question to Siri that what is the good Japanese restaurant or Chinese restaurant so you can get the recommendation. Siri actually answers your question based on the big data that Siri has. Not only just Cloud computing or smartphones, also unmanned car, which one is automated car is also could be produced or could be activated based on big data, and maybe all different kinds of robots are also activated, or people can use the robots based on the big data and also mass storage and IoT or even drones. You can check all the navigation data. We're gathering the navigation data through or with drones. So today, we've talked about or we covered the Fourth Industrial Revolution and big data. Next, we will talk about the intuitions and big data.
