Parsing as Pretraining
(2020)
[Abstract] Recent analyses suggest that encoders pretrained for language
modeling capture certain morpho-syntactic structure.
However, probing frameworks for word vectors still do not report
results on standard setups ...
A Unifying Theory of Transition-based and Sequence Labeling Parsing
(International Committee on Computational Linguistics, 2020-12)
[Absctract]: We define a mapping from transition-based parsing algorithms that read sentences from left to right to sequence labeling encodings of syntactic trees. This not only establishes a theoretical relation between ...
Discontinuous Constituent Parsing as Sequence Labeling
(Association for Computational Linguistics, 2020-11)
[Absctract]: This paper reduces discontinuous parsing to sequence labeling. It first shows that existing reductions for constituent parsing as labeling do not support discontinuities. Second, it fills this gap and proposes ...
Bracketing Encodings for 2-Planar Dependency Parsing
(International Committee on Computational Linguistics, 2020-12)
[Absctract]: We present a bracketing-based encoding that can be used to represent any 2-planar dependency tree over a sentence of length n as a sequence of n labels, hence providing almost total coverage of crossing arcs ...
Cognitive Constraints Built into Formal Grammars: Implications for Language Evolution
(Ravignani, A., Barbieri, C., Martins, M., Flaherty, M., Jadoul, Y., Lattenkamp, E., Little, H., Mudd, K., Verhoef, T., 2020-04-17)
[Abstract] We study the validity of the cognitive independence assumption using an ensemble of artificial syntactic structures from various classes of dependency grammars. Our findings show that memory limitations have ...
Transition-based Semantic Dependency Parsing with Pointer Networks
(Association for Computational Linguistics (ACL), 2020-07)
[Abstract]: Transition-based parsers implemented with Pointer Networks have become the new state of the art in dependency parsing, excelling in producing labelled syntactic trees and outperforming graph-based models in ...
Una herramienta para la ayuda a la redacción de textos académicos (HARTA) como uso de las TIC en el proceso de escritura
(REDINE (Red de Investigación e Innovación Educativa), 2020)
[Resumen] Los estudiantes universitarios españoles tienen que hacer frente a un proceso de escritura en el que
no solo tienen que plasmar su conocimiento disciplinar, sino que tienen que hacerlo en un tipo de
registro ...
Syntactically enriched multilingual sentiment analysis
(CEUR-WS, 2020)
[Abstract]: Sentiment analysis of natural language texts needs to deal with linguistic phenomena like negation, intensification or adversative clauses. In this talk, I present an approach to tackle such phenomena by means ...
