Báo cáo khoa học: "Correcting Errors in a Treebank Based on Synchronous Tree Substitution Grammar" pot

... University Furo-cho, Chikusa-ku, Nagoya, 464-8601 Japan yosihide@el.itc.nagoya-u.ac.jp Abstract This paper proposes a method of correct- ing annotation errors in a treebank. By us- ing a synchronous grammar, the ... method transforms parse trees containing annota- tion errors into the ones whose errors are corrected. The synchronous grammar is automatically induced from the...
