Jacy

The Jacy Japanese grammar (Siegel, Bender, & Bond, 2016; Siegel & Bender, 2002) is a broad-coverage HPSG grammar of Japanese. In combination with a parser (such as the LKB, ACE, or agree), it can analyze Japanese sentences, yielding derivation trees and MRS semantic representations, and also generate sentences from semantic representations.

Input sentences are tokenized using a morphological analyzer like MeCab.

Quick Start

The ACE parser/generator works on Linux and Mac machines. After installing ACE, the following commands will let you parse and generate with Jacy:

~$ git clone https://github.com/delph-in/jacy.git
~$ cd jacy/
~/jacy$ ace -g ace/config.tdl -G jacy.dat
~/jacy$ echo "太郎 が 次郎 に 本 を 渡し た" | ace -g jacy.dat
[...]
