¿µ¹®³»¿ë¿ä¾à In the mid-2000s, the phrase structure tagged corpus of 21st Century Sejong Project enables many phrase structure analysis studies for Korean. And, since the mid-2000s, dependency structure analysis became the mainstream of the structure analysis area, many researchers used the Sejong phrase structure tagged corpus after converting to a dependency tagged corpus. But, because there isn¡¯t a clear representation standard for the Korean dependency structure, each of the individual researchers have carried out research based on different dependency structures, and the research efficiency are significantly deteriorated.
In order to solve this problem, this standard is to establish dependency tag sets and dependency relation establishment methods for Korean.
Because the Sejong phrase structure tagged corpus is the largest structure tagged corpus for Korean, this standard used same tag sets with the sejong corpus to utilize it. In addition, to apply results of foreign dependency structure analysis studies to Korean, the single head constraint and the projective constraint, which are generally used constraints in English study, are applied. Lastly, in order to reflect the unique characteristics of Korean, the head final principle is also applied.
