Building a dictionary with lindera-ko-dic command:

Dictionary format

Information about the dictionary format and part-of-speech tags used by mecab-ko-dic id documented in this Google Spreadsheet, linked to from mecab-ko-dic's repository 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	Name (Korean)	Name (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
