Non-Projective Dependency Parsing with Non-Local Transitions
Daniel Fernández-González, Carlos Gómez-Rodríguez
We present a novel transition system, based on the Covington non-projective parser, introducing non-local transitions that can directly create arcs involving nodes to the left of t…
Towards Syntactic Iberian Polarity Classification
David Vilares, Marcos Garcia, Miguel A. Alonso +1
Lexicon-based methods using syntactic rules for polarity classification rely on parsers that are dependent on the language and on treebank guidelines. Thus, rules are also dependen…
A dependency look at the reality of constituency
Xinying Chen, Carlos Gómez-Rodríguez, Ramon Ferrer-i-Cancho
A comment on "Neurophysiological dynamics of phrase-structure building during sentence processing" by Nelson et al (2017), Proceedings of the National Academy of Sciences USA 114(1…
A non-projective greedy dependency parser with bidirectional LSTMs
David Vilares, Carlos Gómez-Rodríguez
The LyS-FASTPARSE team presents BIST-COVINGTON, a neural implementation of the Covington (2001) algorithm for non-projective dependency parsing. The bidirectional LSTM approach by…
A Full Non-Monotonic Transition System for Unrestricted Non-Projective Parsing
Daniel Fernández-González, Carlos Gómez-Rodríguez
Restricted non-monotonicity has been shown beneficial for the projective arc-eager dependency parser in previous research, as posterior decisions can repair mistakes made in previo…
Generic Axiomatization of Families of Noncrossing Graphs in Dependency Parsing
Anssi Yli-Jyrä, Carlos Gómez-Rodríguez
We present a simple encoding for unlabeled noncrossing graphs and show how its latent counterpart helps us to represent several families of directed and undirected graphs used in s…
On the relation between dependency distance, crossing dependencies, and parsing. Comment on "Dependency distance: a new perspective on syntactic patterns in natural languages" by Haitao Liu et al
Carlos Gómez-Rodríguez
Liu et al. (2017) provide a comprehensive account of research on dependency distance in human languages. While the article is a very rich and useful report on this complex subject,…
How Important is Syntactic Parsing Accuracy? An Empirical Evaluation on Rule-Based Sentiment Analysis
Carlos Gómez-Rodríguez, Iago Alonso-Alonso, David Vilares
Syntactic parsing, the process of obtaining the internal structure of sentences in natural languages, is a crucial task for artificial intelligence applications that need to extrac…
Are crossing dependencies really scarce?
Ramon Ferrer-i-Cancho, Carlos Gomez-Rodriguez, J. L. Esteban
The syntactic structure of a sentence can be modelled as a tree, where vertices correspond to words and edges indicate syntactic dependencies. It has been claimed recurrently that…
