Annotation repositioning methods in the XML documents: Context-based approach

Abstract

This paper presents context-based repositioning methods for annotations in the XML document. In the proposed methods, the XML-based original document and annotation information are presented as logical structure trees, and candidate anchors are produced in the process of creating matching relations between the trees. To select an appropriate candidate anchor among many candidates, repositioning rules are presented by stages based on the textual data and label information of anchor nodes of the logical structure trees. As a result, annotations in the structured document are robustly positioned even after various modifications of contexts in the document.
