東京大学の学生でプログラミング言語開発支援の研究をしています。かつて自然言語処理や計算言語学の研究をしていました。

研究内容

卒論プログラム変換における規則の抽出Google Code Jam 2010 の問題を題材に、愚直なプログラムから効率のよいプログラムへのプログラム運算に使える規則の抽出を試みた。
修論多言語混合文書の言語による分割Wikipedia などに見られる1つの文書内に記述言語の異なる文が混在するような文書について、データ圧縮を利用した分割を試みた。対象は約400言語。

YAMAGUCHI Hiroshi

I'm a student at The University of Tokyo. I am working on supporting systems for developing programming languages. And, I worked on Natural Language Processing or Computational Linguistics in the past.

Research Topic

BachelorExtraction of rules for program transformationUsing the problems of Google Code Jam 2010, I tried to extract a program calculation rule from naive programs to efficient programs.
MasterSegmentation of multilingual mixed texts by languageI tried to split multilingual mixed texts, which contain sentences written in two or more different laguages in a single text, often found in Wikipedia, using data-compression. The target languages are about 400.
