Abstract

When creating annotation information in a free~form environment, ambiguity arises during the analysis stage between geometric information and the annotations. This needs to be resolved so that the accurate creation of annotation information in a free-form annotation environment is possible. This paper identifies and analyzes the ambiguities, specifying methods that are tailored to each of the various contexts that can cause conflicts with free-form marking in a XML-based annotation environment. The proposed general method is based on context which includes various textual and structure information between free-form marking and the annotations themselves. The context information used is expressed in XML based DTD, within the paper. The results are printed and shared through a system specifically implemented for this study. The results from the implementation of the Proposed method show that the annotated areas included in the free-form marking information are more accurate, achieving more accurate exchange results amongst multiple users in a heterogeneous document environment.

정확한 자유형 annotation 정보를 생성하기 위해서는 자유형 마킹의 기하 정보와 대상문서 내용(context)간에 영역 추출 과정에서 발생하는 모호성들을 인식 및 해결할 수 있어야 한다. 따라서 본 논문에서는 먼저 XML 기반의 annotation 환경에서 자유형 마킹과 다양한 내용간에 발생할 수 있는 모호성을 분석하였으며 이를 해결하기 위한 기법을 제안한다. 제안 기법은 자유형 마킹과 annotation이 생성된 영역간의 다양한 비구조 및 구조정보를 포함하는 내용을 기반으로 한다. 제안 기법에 의하여 분석 및 판별된 annotation 정보는 본 논문에서 정의한 XML 기반의 DTD로 표현되며, 본 연구에서 구현한 시스템을 통하여 출력 및 교환된다. 그 결과 본 연구의 제안 기법을 통하여 생성된 자유형 마킹 정보는 기존의 기법보다 정확한 annotation 영역을 포함하며, 다중사용자 및 서로 다른 문서환경에서도 명확한 교환을 가능케 할 수 있다.
