Shaonan Zhu · Acta Geodaetica et Cartographica Sinica · 2012
Corpus annotation is a task to provide both reference and training material for method development and benchmark data sets annotated with a given annotation scheme.After analysis of the linguistic characteristics,an annotation scheme is proposed for markup linguistic expressions for spatial relations in Chinese text.And then a natural language processing software-GATE(General Architecture for Text Engineering) is introduced as the annotation tool.Based on the proposed annotation scheme,a corpus with Encyclopedia of China Geography as the source data is annotated by means of cross-validation to solve the problem of annotation inconsistency.In order to realize the structurized representation of geographical spatial relations described in natural language,and to provide standard training and test data for their extraction.
