Robust, Lexicalized Native Language Identification

Lexicalized vs. Delexicalized Parsing in Low-Resource Scenarios

We present a systematic analysis of lexicalized vs. delexicalized parsing in low-resource scenarios, and propose a methodology to choose one method over another under certain conditions. We create a set of simulation exp…

Multilingual discriminative lexicalized phrase structure parsing

Natural Language Generation in Dialogue using Lexicalized and Delexicalized Data

Natural language generation plays a critical role in spoken dialogue systems. We present a new approach to natural language generation for task-oriented dialogue using recurrent neural networks in an encoder-decoder fram…

Bootstrapping UD treebanks for Delexicalized Parsing

Standard approaches to treebanking traditionally employ a waterfall model (Sommerville, 2010), where annotation guidelines guide the annotation process and insights from the annotation process in turn lead to subsequent …

Delexicalized Word Embeddings for Cross-lingual Dependency Parsing

This paper presents a new approach to the problem of cross-lingual dependency parsing, aiming at leveraging training data from different source languages to learn a parser in a target language. Specifically, this approac…
