Feature schema

Information about the dictionary format and part-of-speech tags used by mecab-ko-dic is documented in this Google Spreadsheet, linked to from mecab-ko-dic's repo readme.

Note how ko-dic has one less feature column than NAIST JDIC, and has an altogether different set of information (e.g. doesn't provide the "original form" of the word).

The tags are a slight modification of those specified by 세종 (Sejong), whatever that is. The mappings from Sejong to mecab-ko-dic's tag names are given in tab "태그 v2.0" on the above-linked spreadsheet.

The dictionary format is specified fully (in Korean) in tab "사전 형식 v2.0" of the spreadsheet. Any blank values default to *.

index	role (Korean)	role (English)	notes
0	품사 태그	part-of-speech tag	See "태그 v2.0" tab on spreadsheet
1	의미 부류	meaning	(too few examples for me to be sure)
2	종성 유무	presence or absence	T for true; F for false; else *
3	읽기	reading	usually matches surface, but may differ for foreign words e.g. Chinese character words
4	타입	type	One of: Inflect (활용); Compound (복합명사); or Preanalysis (기분석)
5	첫번째 품사	first part-of-speech	e.g. given a part-of-speech tag of "VV+EM+VX+EP", would return VV
6	마지막 품사	last part-of-speech	e.g. given a part-of-speech tag of "VV+EM+VX+EP", would return EP
7	표현	expression	"활용, 복합명사, 기분석이 어떻게 구성되는지 알려주는 필드" – Fields that tell how usage, compound nouns, and key analysis are organized
