Step by step: underspecified markup in incremental rhetorical analysis

While quite a few linguistic corpora with syntactic annotations are available today, resources are scarce on the level of discourse annotation. A flexible, extendible annotation format speeds up development. We therefore propose an XML format for annotating rhetorical structure trees. In human and automatic analysis, rhetorical structure is often difficult and assigned incrementally. Thus, the ...

A Decision-Based Approach to Rhetorical Parsing

We present a shift-reduce rhetorical parsing algorithm that learns to construct rhetorical structures of texts from a corpus of discourse-parse action sequences. The algorithm exploits robust lexical, syntactic, and semantic knowledge sources.

Shallow Parsing and Text Chunking: a View on Underspecification in Syntax

This paper illustrates a technique of shallow parsing named “text chunking” whereby “parse incompleteness” is reinterpreted as “parse underspecification”. A text is chunked into structured units which can be identified with certainty on the basis of available knowledge. The chunking process stops at that level of granularity beyond which the analysis gets undecidable. We argue that a chunked sy...

Robust Text Analysis via Underspecification

This paper is concerned with the robust analysis of the discourse structure of a text via underspecification. Most current discourse theories (e.g. Rhetorical Structure Theory (RST) by Mann and Thompson (1988), Abduction by Hobbs et al. (1993) or Segmented Discourse Representation Theory (SDRT) by Asher (1993)) require detailed world and context knowledge for the derivation of the discourse str...
