高等研究所 訪問研究員 セミナー:
Professor GONZALEZ, Luis Millan “Analysis of the Presence of Japanese Judokas on Social Media” (4/15)
主 旨 / Outline
In recent years, social media (SM) has played a crucial role in our society.
People regularly post content related to their professional and personal lives, either to promote themselves or simply to feel more connected to their social environment.
Athletes, of course, have also found social media to be an effective way to share their progress and achievements with the world. Given this context, it is important to understand the impact that athletes’ posts have on society. Analyzing the opinions expressed by people on these platforms provides valuable insights into how athletes are perceived by the general public. Naturally, Japanese judokas have a significant impact within the global judo community, and therefore, it is essential to monitor the public’s opinion of this select group of athletes.
The aim of this seminar is to provide an overview of the key techniques necessary for social media analysis in English. The seminar will focus on one of the most widely used social media platforms in the West (i.e., X, formerly known as Twitter).
We will cover the essential aspects of social media analysis, specifically:
i. automated data downloading using programming languages,
ii. description of key metadata on the platform,
iii. extraction of variables and text preprocessing,
iv. text mining techniques (LDA analysis, sentiment analysis, etc.),
and v. network analysis based on graph theory.
During the seminar, we will present examples of the impact of certain Japanese judokas on Twitter.
These results are part of the analyses I will conduct during my stay at Waseda University.
講演者 / Speaker
GONZALEZ, Luis Millan (Full Professor of Sports Science, University of Valencia, Spain)
Biography:
I am a Full Professor at the Faculty of Sports Science, University of Valencia,
where I teach Judo in the Bachelor‘s program in Sports Science and Advanced
Statistics in the Research Master’s program. As a former member of the Spanish
National Judo Team, I have integrated my athletic experience into my academic
career. My research focuses on applying advanced analytical methods to sports
science. Using programming languages like MATLAB and LabVIEW, I have
conducted studies on biological and biomechanical signals, employing techniques
such as the Fast Fourier Transform and Wavelet Transform to analyze swimming,
human balance, and judo performance. I also specialize in neural networks, a
cutting-edge statistical tool for the social sciences. My multidisciplinary approach
has fostered impactful research and successful collaborations. My work
emphasizes making complex data analysis accessible, and bridging advanced
analytics with practical applications to drive innovation in sports science and
education.
