옛한글･현대한글 병렬 자료를 활용한 옛한글 형태소 사전 구축 기법 연구 = A Study on Technique of Constructing Old-Korean Morphological Dictionary by Using Old-Modern Korean Parallel Material

다국어 초록 (Multilingual Abstract)

Morphological analysis of a document written in a natural language provides fundamental information for syntactic analyzing and semantic analyzing. And this is an essential process to develop computer applications based on natural language processes. In developing an old Korean morphological analyzing system, constructing an old Korean morphological dictionary is essential and the number of morphemes registered in the dictionary has a significant impact on the quality and performance of the analysis. However, the development of morphological analyzer and morphological dictionary for old Korean has been slow because old Korean is not used anymore and the demand of processing documents written in old Korean is limited.
In this paper, we proposed a technique to construct an old Korean morphological dictionary. After morphologically analyzing a document written in modern Korean, the resulting modern Korean morphemes are searched in a parallel document written in old Korean by using a similarity measure. For accurate and efficient retrieval of a particle, a modern-old particle table is constructed and used. If an old Korean morpheme corresponding to the modern Korean morpheme is found, the morpheme is registered in an old Korean morphological dictionary. If it is not found, a highly probable item in a word order is extracted and it is registered based on the user’s decision.
