DANGNT@UIT.VNU-HCM at SemEval 2019 Task 1: Graph Trans-formation System from Stanford Basic Dependencies to Universal Conceptual Cognitive Annotation (UCCA)

摘要

This paper describes the graph transformation system (GT System) for SemEval 2019 Task 1: Cross-lingual Semantic Parsing with Universal Conceptual Cognitive Annotation (UCCA)~1. The input of GT System is a pair of text and its unannotated xml, which is a layer 0 part of UCCA form. The output of GT System is the corresponding full UCCA xml. Based on the idea of graph illustration and transformation, we perform four main tasks when building GT System. At the first task, we illustrate the graph form of Stanford dependencies~2 of input text We then transform into an intermediate graph in the second task. At the third task, we continue to transform into ouput graph form. Finally, we create the output UCCA xml The evaluation results show that our method generates good-quality UCCA xml and has a meaningful contribution to the semantic representation sub-field in Natural Language Processing.
