Syntactic representations based on word-to-word dependencies have a long-standing tradition
in descriptive linguistics, and receive considerable interest in many applications. Nevertheless,
dependen...
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...
Punctuation:Making a Point in Unsupervised Dependency Parsing
Punctuation Unsupervised Dependency Parsing
2015/6/10
We show how punctuation can be used to improve unsupervised dependency parsing. Our linguistic analysis confirms the strong connection between English punctuation and phrase boundaries in the Penn Tre...
Lateen EM: Unsupervised Training with Multiple Objectives,Applied to Dependency Grammar Induction
Lateen EM Unsupervised Training Multiple Objectives Dependency Grammar Induction
2015/6/10
We present new training methods that aim to mitigate local optima and slow convergence in unsupervised training by using additional imperfect objectives. In its simplest form, lateen EM alternates bet...
Capitalization Cues Improve Dependency Grammar Induction
Capitalization Cues Grammar Induction
2015/6/10
We show that orthographic cues can be helpful for unsupervised parsing. In the Penn Treebank, transitions between upper- and lowercase tokens tend to align with the boundaries of base (English) noun p...
Three Dependency-and-Boundary Models for Grammar Induction
Three Dependency Boundary Models Grammar Induction
2015/6/10
We present a new family of models for unsupervised parsing, Dependency and Boundary models, that use cues at constituent boundaries to inform head-outward dependency tree generation. We build on three...
Bootstrapping Dependency Grammar Inducers from Incomplete Sentence Fragments via Austere Models
Dependency Grammar Induction Unsupervised Dependency Parsing Curriculum Learning Partial EM Punctuation Unsupervised Structure Learning
2015/6/10
Modern grammar induction systems often employ curriculum learning strategies that begin by training on a subset of all available input that is considered simpler than the full data. Traditionally, fil...
Accurate scoring of syntactic structures
such as head-modifier arcs in dependency parsing typically requires rich, highdimensional feature representations.
