Annotation of anaphoric relations in biomedical full-text articles using a domain-relevant scheme
نویسندگان
چکیده
Biomedical literature has been the focus of relevant information extraction projects, however there is no corpus of full scientific articles annotated with anaphoric links for training and evaluation of anaphora resolution systems—which are an important part of information extraction efforts—for this domain. We have created a corpus of biomedical articles that are annotated with anaphoric links between noun phrases referring to the biomedical entities of our interest, using an annotation scheme that aims to capture the domain relations that link the entities.

Annotation of Coreference Relations Among Linguistic Expressions and Images in Biological Articles
In this paper, we propose an annotation scheme which can be used not only for annotating coreference relations between linguistic expressions, but also those among linguistic expressions and images, in scientific texts such as biomedical articles. Images in biomedical domain often contain important information for analyses and diagnoses, and we consider that linking images to textual descriptio...
متن کاملInfluence of Text Type and Text Length on Anaphoric Annotation
We report the results of a study that investigates the agreement of anaphoric annotations. The study focuses on the influence of the factors text length and text type on a corpus of scientific articles and newspaper texts. In order to measure inter-annotator agreement we compare existing approaches and we propose to measure each step of the annotation process separately instead of measuring the...
متن کاملAnnotation of Biomedical Texts for Zone Analysis
This document provides the framework of the annotation scheme of biomedical texts for zone analysis (ZA, Mizuta and Collier 2004a, 2004b) in the hope that this annotation scheme will be useful for enabling improved access to information contained in biomedical texts. It is intended to serve as a set of guidelines for building annotated corpora for ZA and is neutral to the mark-up language/tool ...
متن کاملWikiCoref: An English Coreference-annotated Corpus of Wikipedia Articles
This paper presents WikiCoref, an English corpus annotated for anaphoric relations, where all documents are from the English version of Wikipedia. Our annotation scheme follows the one of OntoNotes with a few disparities. We annotated each markable with coreference type, mention type and the equivalent Freebase topic. Since most similar annotation efforts concentrate on very specific types of w...
متن کاملAnaphoric Annotation in the ARRAU Corpus
Arrau is a new corpus annotated for anaphoric relations, with information about agreement and explicit representation of multiple antecedents for ambiguous anaphoric expressions and discourse antecedents for expressions which refer to abstract entities such as events, actions and plans. The corpus contains texts from different genres: task-oriented dialogues from the Trains-91 and Trains-93 cor...
