필적 감정서에서 특이성과 빈도의 가중치가 높은 글자로 선택되어 사용된 글자를 자음별로 구분하였을 때 ‘ㅅ, ㅈ 및 ㅎ’의 자음에서 추출된 세부 특징의 수도 많고 유형별로 구분되는 수도 다양하여 감정에 많이 활용되는 것을 확인하였다. 필적 감정서에 특이성과 빈도의 가중치가 높아 세부특징 글자에 사용된 글자는 1건에서만 나타나는 글자가 82% 정도로 특정한 글자만 가지고 감정을 하는 것은 적합하지 않음을 확인하였다. 한글 자음을 유형별로 1차 및 2차로 세부 분류하고 가중치를 결정한 결과, 자음 ‘ㄷ, ㄹ, ㅂ 및 ㅌ’의 유형만 가중치가 2로 결정되었다. 그리고 나머지는 모두 가중치가 3으로 결정되었으며 추출된 글자 자체가 특이성과 빈도수가 높은 글자를 감정서에 활용한 것이므로 이 같은 결과가 나타난 것을 알 수 있었다.
Abstract
As a lot of handwriting characteristics have been extracted from consonants “ㅅ, ㅈ, and ㅎ” and these consonants can be divided into many types, the weight score of the frequency and uniqueness for the consonants “ㅅ, ㅈ, and ㅎ” have been high, resulting in frequent use of the consonants for handwriting examination. The percentage of a certain letter with high uniqueness and frequency that appeared during a single handwriting examination is 82%, implying that conducting examinations using only 1 letter is unwise. Korean consonants were classified into two groups by the consonant's type and then weight score of each consonant was analyzed. The consonants “ㄷ, ㄹ, ㅂ, and ㅌ” received a weight score of 2 and the rest received a weight score of 3. The analyzed characters themselves, which have high uniqueness and frequency, were utilized in the examination report, resulting in such results.
