Exploiting Coreference Annotations for Text-to-Hypertext Conversion
Anke Holler, Jan Frederik Maas, Angelika Störrer · 2004
The paper describes an annotation scheme for coreference developed within the application context of text-to-hypertext conversion. In this context coference is used (1) for generating document-internal and cross-document hyperlinks, and (2) for resolving anaphoric expressions in order to achieve cohesive closedness in hypertext nodes. We will argue that for the purpose of cross-document linking it is necessary to separate the annotation of coreference relations from the annotation of anaphoric relations. To account for this requirement, we developed a knowledge-based annotation scheme that relates referential expressions in the text to entities in a knowledge representation, which is modeled using XML Topic Maps. 1. Project Framework Converting linear text documents into documents that can be published in a hypertext environment is a complex task requiring conversion software on the technical side as well as conversion strategies and methods on the conceptual side. In the project HyTex1, which is the framework of the approach discussed in this paper, we concentrate on principles and strategies for handling conceptual problems
