Parsing Linear Context-Free Rewriting Systems with Fast Matrix Multiplication
Subset of recognition algorithm the binary linear system M matrix multiplication grammar rules subroutine
2016/10/31
We describe a recognition algorithm for a subset of binary linear context-free rewriting systems (LCFRS) with running time O(nωd) where M(m) = O(mω) is the running time for m × m matrix multiplication...
Transition-Based Parsing for Deep Dependency Structures
Analysis of structure depth dependency structure language data drive
2016/10/31
Derivations under different grammar formalisms allow extraction of various dependency structures. Particularly, bilexical deep dependency structures beyond surface tree representation can be derived f...
Synchronous Context-Free Grammars and Optimal Parsing Strategies
Synchronous Context-Free Grammars Optimal Parsing Strategies
2016/7/7
The complexity of parsing with synchronous context-free grammars is polynomial in the sentence
length for a fixed grammar, but the degree of the polynomial depends on the grammar. Specifi-
cally, th...
We present techniques for automatically parsing existing sewing
patterns and converting them into 3D garment models. Our parser
takes a sewing pattern in PDF format as input and starts by extracting...
Query Understanding Enhanced by Hierarchical Parsing Structures
query understanding semantic tagging linguistic parsing
2016/1/23
Query understanding has been well studied in the areas of information retrieval and spoken language understanding(SLU). There are generally three layers of query understanding: domain classification, ...
A Statistical Parsing Framework for Sentiment Classification
Statistical Parsing Framework Sentiment Classification
2015/9/15
We present a statistical parsing framework for sentence-level sentiment classification in this article. Unlike previous works that use syntactic parsing results for sentiment analysis, we develop a st...
Frame-Semantic Parsing
Frame-Semantic linguistics
2015/9/14
Frame semantics is a linguistic theory that has been instantiated for English in the FrameNet
lexicon. We solve the problem of frame-semantic parsing using a two-stage statistical model
that takes l...
Divisible Transition Systems and Multiplanar Dependency Parsing
Divisible Transition Systems Multiplanar Dependency Parsing
2015/9/11
Transition-based parsing is a widely used approach for dependency parsing that combines high efficiency with expressive feature models. Many different transition systems have been proposed, often form...
Morphological and Syntactic Case in Statistical Dependency Parsing
Morphological and Syntactic Dependency Parsing
2015/9/11
Most morphologically rich languages with free word order use case systems to mark the grammatical function of nominal elements, especially for the core argument functions of a verb. The
standard pipe...
Parsing Morphologically Rich Languages: Introduction to the Special Issue
Languages Special Issue
2015/9/11
Parsing is a key task in natural language processing. It involves predicting, for each natural
language sentence, an abstract representation of the grammatical entities in the sentence and
the relat...
Knowledge Sources for Constituent Parsing of German, a Morphologically Rich and Less-Configurational Language
German Less-Confi gurational Language
2015/9/11
We study constituent parsing of German, a morphologically rich and less-configurational
language. We use a probabilistic context-free grammar treebank grammar that has been adapted
to the morp...
Word Segmentation, Unknown-word Resolution, and Morphological Agreement in a Hebrew Parsing System
Word Segmentation, Unknown-word Resolution
2015/9/11
We present a constituency parsing system for Modern Hebrew. The system is based on the
PCFG-LA parsing method of Petrov et al. (2006), which is extended in various ways in order
to accommodate the s...
Multilingual Joint Parsing of Syntactic and Semantic Dependencies with a Latent Variable Model
Multilingual Joint Parsing Syntactic Semantic Latent Variable Model
2015/9/11
Current investigations in data-driven models of parsing have shifted from purely syntactic analysis to richer semantic representations, showing that the successful recovery of the meaning of text requ...
Dependency Parsing of Modern Standard Arabic with Lexical and Inflectional Features
Standard Arabic Infl ectional Features
2015/9/11
We explore the contribution of lexical and inflectional morphology features to dependency
parsing of Arabic, a morphologically rich language with complex agreement patterns. Using controlled ex...
Incremental,Predictive Parsing with Psycholinguistically Motivated Tree-Adjoining Grammar
Incremental Predictive Parsing Psycholinguistically Tree-Adjoining Grammar
2015/9/11
Psycholinguistic research shows that key properties of the human sentence processor are incrementality, connectedness (partial structures contain no unattached nodes), and prediction (upcoming syntact...
