Lecture at 2014 Financial Informatics Seminar

October 03, 2014

I’m Kota Tsubouchi of Yahoo! JAPAN Research.

I presented my paper “株価掲示板データを用いたファイナンス用ポジネガ辞書の生成 ” at the 2014 Financial Informatics Seminar on September 22. Please see my paper for the substance of the presentation.

This seminar was held by Sig-Fin (Special Interest Group on Financial Informatics), and it took place in a meeting room at Thomson Reuters. And what a fabulous, high-tech meeting room!

I’m not a financial specialist; I dabbled in stocks and investment when I was in college. My work at Yahoo! JAPAN involves data analysis to gain insights from Yahoo! JAPAN’s accumulated data. The fact that, in spite of that, I was able to speak in front of the specialists at the seminar and hold their interest made me realize anew that I could only do that thanks to the massive volume of Yahoo! Finance’s stock price board data and the quality of its posts.

The venue overlooks the Diet Building, and I felt able to speak very fluently. There were lots of questions, and the discussion became quite lively.
