X. Warranty

Currently, its version number is 1.0.0 (beta). The major improvement from the previous version is speed-up. For more, look brief change log file.

Because the first purpose of this morphological analyzer is completed (speed/output of MoA etc), I determine the version number is 1. But it doesn't mean that there is no problems in MoA as a practical and perfect Morphological Anaylzer. There is so much remained problems in this area to be solved. But not now. so for a while, there is only minor patch for this program.

This program follows CopyLeft of GNU.


0. What is MoA ?

MoA is an Morphological Analyzer for Korean language. Morphological analyzer(in short, I will call this "MA") is needed to make some good(?) information retrieval tool or natural language processing.

For example, in Korean, "Na-Nun Gong-Bu-Lul Han-Da.", then MA will says to you that "Na+Nun Gong-Bu+Lul Han+Da." according to their POS(part-of-speech). For more example, look raw data and interpreted data (both file contains KS code - Korean characters).

MoA is that kinda program and specialized to Korean Language only. I don't know the scheme used in MoA can be applied to the other Languages.

1. General introduction

There is public morphological analyzer written by Sang-Ho, Lee, that is, KTS (Korean Tagging System, you can get it from cair-archive's its directory). But it have some disadvantages which it cannot be changed easily because it is tightly coupled with tagging system.

So I rewrite morphological analyzer(it is my first job in laboratory) for Korean language with great help from Jae-Hoon, Kim and Sang-Ho, Lee.

Because I didn't know in detail about the previous effort concentrated to this kind algorithm, I follow the instructions from Kim. But mainly I thought to generalize the concepts used in morphological analysis so the beginner know well in detail and modify the sources by his own efforts.

3. Test machine/OS

machine : SS2, OS : SunOS 4.1.2 KLE

4. Main problem

MoA have some problems now which cannot be solved easily.
And miscellary things to do related to MoA sources are listed in "TODO" file only for me.
