Chunking + Island-Driven Parsing = Full Parsing
We present a novel method for improving parsing performance, using a stochastic islanddriven chart parser preceded by a chunking process for identifying initial islands. Two different stochastic models have been developed for the island-driven parsing. Some experiments with nominal chunking using broad-coverage grammars derived from the Penn Treebank have been performed with remarkable results.
متن کاملParsing Speech Repair without Specialized Grammar Symbols
This paper describes a parsing model for speech with repairs that makes a clear separation between linguistically meaningful symbols in the grammar and operations specific to speech repair in the operation of the parser. This system builds a model of how unfinished constituents in speech repairs are likely to finish, and finishes them probabilistically with placeholder structure. These modified...
متن کاملLearning Visual Symbols for Parsing Human Poses in Images
Parsing human poses in images is fundamental in extracting critical visual information for artificial intelligent agents. Our goal is to learn selfcontained body part representations from images, which we call visual symbols, and their symbolwise geometric contexts in this parsing process. Each symbol is individually learned by categorizing visual features leveraged by geometric information. In...
متن کاملIsland parsing and bidirectional charts
Chart parsing is directional in the sense that it works from the starting point (usually the beginning of the sentence) extending its activity usually in a rightward manner. We shall introduce the concept of a chart that works outward from islands and makes sense of as much of the sentence as it is actually possible, and after that will lead to predictions of missing fragments. So, for any plac...
