The application discloses a Korean
input method, an
input device and an electronic device, and relates to the technical field of input methods. The Korean
input method comprises the following steps: obtaining a Korean character input by a user; performing single-character
processing on the Korean character based on the input sequence of the Korean character, determining combinations capable of forming a
single character and characters incapable of forming a
single character; directly decoding the combinations capable of forming a
single character into single characters, and performing a completion operation based on the single characters and / or the characters incapable of forming a single character to obtain new candidate words and / or candidate characters. The application firstly establishes a Korean basic term model, performs character forming
processing on Korean characters through a Korean maximum
combination algorithm, expands single characters into word groups through the Korean basic term model, expands Korean characters into Korean single characters, and trains the Korean basic term model according to the last selection of a user, thereby providing more suitable expansion results for the user and improving input efficiency during input.
