Syntactic Semantic Correspondence in Dependency Grammar

Abstract

This paper describes the semantic format of the UAIC Ro-Dia Dependency Treebank, based on the previous classical syntactic annotation. The discussed format exploits all the semantic information annotated in the morphological level. The transformation of syntactic annotation into semantic one is made semi-automatically, using a tool called Treeops, which is a converter of an XML format to another XML format, in accordance with a set of rules. Non-ambiguous syntactic relations are transformed automatically, while ambiguous ones are manually corrected. The paper also contains some explanations of the generic rapport between syntactic and semantic structures. We elaborated a set of types of judgement which govern the selection of semantic roles for the syntactic tags based on the morphological ones, which are ambiguous for the semantic annotation. After the creation of the large enough semantically annotated corpus, a statistical semantic parser will be trained for the further automate annotation of ambiguous syntactic relations.
