Linguistics: Mathematical Approach of Historical Changes of Language

Theme of this laboratory is:

``If we could see a figure of language, what would it be?''

There are five senses such as `looking', `touching', `listening', `sniffing', `tasting', but this five senses is also a fundamental way of analysis. Among them, the easiest `seeing', so-called `visualization' is one of technologies that has received much attention now. There are many things to understand by seeing, but there are many worlds that cannot be seen than we expected. Language itself is not originally shaped. However, if a language has a form, what a form it is, which is one of the biggest romances. Through visualization of the language, we are conducting research to consider the appearance of language.

Have you thought about such a thing?

• What is linguistic difference between "J-POP Japanese" and "Manga Japanese"?
• Is the "Samurai language in TV" really a "Samurai language of the time"?
• From when does "young girl speech style" change into "middle aged lady speech style"?
• So, what kind of words will hear in 'middle aged lady speech style'?
• When you come to speak English very well, does that English feel like Japanese?
• What is the secret of a foreigner who can speak Japanese fluently like a Japanese?
• Are there any tips for improving your foreign languages?
• Why is honorific expression difficult?
• Can you think of linguistics by mathematics?
• Can I make diagrams (models) of languages with computers?
• How can we make an average love letter a love letter that makes you unexpected?
• How many words can not be examined in the dictionary?
• How do you know the meaning of words that can not be looked up in a dictionary?

If you would like to manage such a simple question, please visit our laboratory.

Information

• Our laboratory is seeking applications: Master and Doctor course students who intend to study linguistics in the field of mathematical modeling and quantitative analysis.
• The subject is not only rigid things such as comparison of "Japanese of modern times", or "Japanese of Heian era."
  • How is "Japanese in comics" and "Japanese in drama" different?
  • How is "Japanese in J-POP" and "Japanese in Enka (Japanese Folk music)" different?
  • How is "Japanese in Manzai (Stand up comedy by two people)" and "Japanese in Rakugo"?
  • How is Japanese different from "Western area Rakugo" and "Eastern area Rakugo"?
• Through these differences, if you want to know what is language? You are very welcome.
• If you would like to study linguistics, theory of language, corpus linguistics at the university of science, please contact us.
• If you have never studied linguistics, please come to our class once.
• If it is for the first time to learn Linguistics, it may be difficult. It is, however, a good idea to be a student as a research student.
• We open courses of linguistics in the department of social and human science. I am lecturing on "Fundamentals of linguistics and applied linguistics".
• Please consider those who have already worked and are considering earning a doctor degree for your future career.
• I will consider of the circumstances of your workplace and I can change the time for advising you to your convenient time.
• Please contact us by e-mail for more information.

Credo

• Doing research for truth.
• Being calm.
• Not cheat.
• Foundation firm.
• A fun moment, a chance to learn.
• If you do, you can do it. If you not do, you will never be able to do it.

• 2018/09/16: JADH 2018 September, 10th, we presented the following paper: "A study on the distribution of cooccurrence weight patterns of classical Japanese poetic vocabulary."; The main point of this paper is that we found that the weighted distribution of co-occurrence patterns (of course, although it may be called co-occurrence) is a normal distribution. Regarding the co-occurrence pattern and the normal distribution, I have ever known it, but I could not present it in the form of a paper for a long time. Regarding the distribution pattern of both tails of the normal distribution, we decided to call the right tail as Content Tail and the left tail as Function Tail. Because it has something similar to that of modern language particles, we used to regard it as a noun located before a particle. Since the shape of the distribution cannot be made consciously by humans, estimating the function of a word from the distribution is essential than a linguist can subjectively make a decision. To put it briefly, I have made such a point.
• 2018/08/11: JADH 2018 September 10th, Hitotsubashi-Hall, we will present "A study on the distribution of cooccurrence weight patterns of classical Japanese poetic vocabulary" and "Collocation Patterns of Pitch-Class Sets: Comparing Mozart's Symphonies and String Quartets."
