Searching in the Penn Discourse Treebank Using the PML-Tree Query
نویسندگان
چکیده
The PML-Tree Query is a general, powerful and user-friendly system for querying richly linguistically annotated treebanks. The present paper shows how the PML-Tree Query can be used for searching for discourse relations in the Penn Discourse Treebank 2.0 mapped onto the syntactic annotation of the Penn Treebank.

A Reranking Model for Discourse Segmentation using Subtree Features
This paper presents a discriminative reranking model for the discourse segmentation task, the first step in a discourse parsing system. Our model exploits subtree features to rerank Nbest outputs of a base segmenter, which uses syntactic and lexical features in a CRF framework. Experimental results on the RST Discourse Treebank corpus show that our model outperforms existing discourse segmenter...
متن کاملBuilding Chinese Discourse Corpus with Connective-driven Dependency Tree Structure
In this paper, we propose a Connectivedriven Dependency Tree (CDT) scheme to represent the discourse rhetorical structure in Chinese language, with elementary discourse units as leaf nodes and connectives as non-leaf nodes, largely motivated by the Penn Discourse Treebank and the Rhetorical Structure Theory. In particular, connectives are employed to directly represent the hierarchy of the tree...
متن کاملAnnotation And Data Mining Of The Penn Discourse TreeBank
The Penn Discourse TreeBank (PDTB) is a new resource built on top of the Penn Wall Street Journal corpus, in which discourse connectives are annotated along with their arguments. Its use of standoff annotation allows integration with a stand-off version of the Penn TreeBank (syntactic structure) and PropBank (verbs and their arguments), which adds value for both linguistic discovery and discour...
متن کاملExperiments on Sense Annotations and Sense Disambiguation of Discourse Connectives
Discourse connectives can be analyzed as discourse level predicates which project predicate-argument structure on a par with verbs at the sentence level. The Penn Discourse Treebank (PDTB) reflects this view in its design providing annotation of the discourse connectives and their arguments. Like verbs, discourse connectives have multiple senses. We present a set of manual sense annotation stud...
متن کاملA Short Introduction to the Penn Discourse TreeBank
Taking discourse connectives to be the predicates of binary discourse relations, the goal of Penn Discourse Treebank (PDTB) is to annotate the million word WSJ corpus in the Penn TreeBank with each of its discourse connectives and their arguments. The paper describes the linguistic observations and ideas that led to the PDTB, the decisions that shaped its content and the tools used in its devel...
