A Relation-Based Schema for Treebank Annotation
نویسندگان
چکیده
This paper presents a relation-based schema for treebank annotation, and its application in the development of a corpus of Italian sentences. The annotation schema keeps arguments and modifiers distinct and allows for an accurate representation of predicate-argument structure and subcategorization. The accuracy strongly depends on methods adopted for defining the relations which are tripartite feature structures that consist of a morpho-syntactic, a functional and a semantic component. We presents empirical evidence for these tripartite structures by illustrating phenomena faced in the development of an Italian treebank.

An annotation scheme for Persian based on Autonomous Phrases Theory and Universal Dependencies
A treebank is a corpus with linguistic annotations above the level of the parts of speech. During the first half of the present decade, three treebanks have been developed for Persian either originally or subsequently based on dependency grammar: Persian Treebank (PerTreeBank), Persian Syntactic Dependency Treebank, and Uppsala Persian Dependency Treebank (UPDT). The syntactic analysis of a sen...
متن کاملRevising the METU-Sabancı Turkish Treebank: An Exercise in Surface-Syntactic Annotation of Agglutinative Languages
In this paper, we present a revision of the training set of the METU-Sabancı Turkish syntactic dependency treebank composed of 4997 sentences in accordance with the principles of the Meaning-Text Theory (MTT). MTT reflects the multilayered nature of language by a linguistic model in which each linguistic phenomenon is treated at its corresponding level(s). Our analysis of the METU-Sabancı synta...
متن کاملSyntactic Dependencies for Multilingual and Multilevel Corpus Annotation
The relevance of syntactic dependency annotated corpora is nowadays unquestioned. However, a broad debate on the optimal set of dependency relation tags did not take place yet. As a result, largely varying tag sets of a largely varying size are used in different annotation initiatives. We propose a hierarchical dependency structure annotation schema that is more detailed and more flexible than ...
متن کاملBuilding a Treebank for Italian: a Data-driven Annotation Schema
Many natural language researchers are currently turning their attention to treebank development and trying to achieve accuracy and corpus data coverage in their representation formats. This paper presents a data-driven annotation schema developed for an Italian treebank ensuring data coverage and consistency between annotation of linguistic phenomena. The schema is a dependency-based format cen...
متن کاملAnnotation Schema Oriented Validation for Dependency Parsing Evaluation
Recent studies demonstrate the effects of various factors on the scores of parsing evaluation metrics and show the limits of evaluation centered on single test sets or treebank annotation. The main aim of this work is at contributing to the debate about the evaluation of treebanks and parsers, and, in particular, about the influence on scores of the design of the annotation schema applied in th...
