Abstract

In order to discern and classify high-quality slides, our research proposes a classification method that utilizes a knowledge structure containing information on the presentation slides. After analyzing whether our knowledge structure captures the content's quality information, we developed a classification method based on the knowledge structure produced from the analysis results. With the proposed method, we compared results classified by quality of presentation slides. Through this comparison, we verified that the slides in the high quality group could be classified and were able to retrieve high quality slides. The results show that, by utilizing the cognitive model of a knowledge structure, our method can increase the effectiveness of classification when search or recommendation is conducted mainly with high-quality slides.

본 연구는 내용적으로 고품질인 슬라이드를 구분하고 분류하기 위해, 슬라이드의 지식정보를 내포하는 지식구조를 이용하는 분류 방법을 제안한다. 지식구조가 슬라이드의 내용적 품질정보를 내포하는지에 대해서 분석한 후, 그 결과로부터 지식구조를 이용한 분류 방법을 개발하였고, 슬라이드의 품질별로 분류한 결과를 비교하였다. 비교를 통해 고품질군에 속하는 슬라이드일수록 높은 품질의 슬라이드 위주로 분류할 수 있다는 점을 검증하였다. 이는 품질이 높은 슬라이드 위주로 검색하거나 추천하고자 할 때, 지식구조라는 인지적 모형을 활용하여 그 효과를 높일 수 있음을 보여준다.
