feature request - reverse conjugation

[ryanckulp]

hi folks,

i've been looking for a library that performs the following:

먹었습니다 # => 먹다
할게요 # => 하다

are there plans to support something like this? alternatively, do you think leveraging this library would be useful to build a reverse conjugator myself?

cheers,
Ryan

You could iterate over all possible verb roots and check if any of them are valid using Paradigm.verb2verb_classes, though there is nothing special about that compared to any dictionary. Once you have found the verb root, you can then just append "다".

For example (using graphemes):

from koparadigm import Paradigm
from jamo import h2j, j2h
from grapheme import graphemes

p = Paradigm()
verb_dict = p.verb2verb_classes


def words(word: str):
    """Generate all possible sub-words by removing jamo from right to left."""
    syllables = list(graphemes(word))
    while syllables:
        end = syllables.pop()
        base_word = "".join(syllables)
        yield base_word + end

        jamo = h2j(end)
        if len(jamo) == 3:
            yield base_word + j2h(*jamo[:-1])


def unconjugate(verb: str):
    if verb in verb_dict:
        return [verb]

    verbs = []
    for v in words(verb):
        if v in verb_dict:
            verbs.append(v)
    return verbs

>>> list(words("먹었습니다"))
['먹었습니다', '먹었습니', '먹었습', '먹었스', '먹었', '먹어', '먹', '머']
>>> unconjugate("먹었습니다")
['먹']
>>> list(words("할게요"))
['할게요', '할게', '할', '하']
>>> unconjugate("할게요")
['하']
