(25) A proposed framework of LTB Japanese Grammar and implementing its rules

The IFS Japanese Morphological Grammar Rules is an implementation for UNIX-based computers of the grammar rules of the Morphological Analysis System LAX -- free software released by ICOT(Institute for New Generation Computer Technology). The IFS grammar rules are designed for the JUMAN Morphological Analysis Engine. Some dictionary data is also added.

With this rule, we can analyze(articulate) Japanese sentences. The morphological grammar system, which this rule is based on, does not depend on a particular part of speech system of syntactic grammar at the most. Thus the result of the analysis is versatile, and can be put into wide variety of usages such as: linguistic researches, and software development applying a natural language processing system.

Functional word (JOJI and SETSUJI) dictionaries are released with rules. There is no general dictionary for content words. Also included in the release are the converted dictionaries from the IPAL freely distributed verb and adjective dictionaries, and from JUMAN 1.0 dictionary with 38,000 entries (without nouns).

Natural language processing

IFS Japanese Morphological Grammar Rules uses JUMAN, Chasen, and Breakfast as morphological analysis engines. This software package contains morphological grammar rules ready for compiling with utility programs attached with JUMAN (Chasen, Breakfast), dictionary data, and utility programs.

The assumed users are researchers of natural language processing and application developers applying natural language processing.

Computers:

UNIX-based computers (such as SunOS Release 4.x) with GNU software (glibc, gcc, etc.) installed.

Analysis Engine:

JUMAN 2.0 or later, Chasen 1.0 or later (can be obtained from NAIST or Kyoto University FTP). System utility programs (makemat, makeint, maketree, etc.) is essential.

AWK:

Probably already installed on BSD UNIX. If not, obtain and install.

PERL:

Probably already installed on BSD UNIX. If not, obtain and install.

Disk Space:

10MB.
