• On the Logistical Difficulties and Findings of Jopara Sentiment Analysis 

  Agüero-Torales, Marvin M.; Vilares, David; López-Herrera, Antonio G. (Association for Computational Linguistics, 2021-06)

  [Abstract] This paper addresses the problem of sentiment analysis for Jopara, a code-switching language between Guarani and Spanish. We first collect a corpus of Guarani-dominant tweets and discuss on the difficulties of ...

• Sequence Tagging for Fast Dependency Parsing 

  Strzyz, Michalina; Vilares, David; Gómez-Rodríguez, Carlos (2019)

  [Abstract] Dependency parsing has been built upon the idea of using parsing methods based on shift-reduce or graph-based algorithms in order to identify binary dependency relations between the words in a sentence. In this ...

• Cognitive Constraints Built into Formal Grammars: Implications for Language Evolution 

  Gómez-Rodríguez, Carlos; Christiansen, Morten H.; Ferrer-i-Cancho, Ramon (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 ...

• Parsing as Pretraining 

  Vilares, David; Strzyz, Michalina; Søgaard, Anders; Gómez-Rodríguez, Carlos (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 ...

• Increasing NLP Parsing Efficiency with Chunking 

  Anderson, Mark Dáibhidh; Vilares, David (M D P I AG, 2018-09-19)

  [Abstract] We introduce a “Chunk-and-Pass” parsing technique influenced by a psycholinguistic model, where linguistic information is processed not word-by-word but rather in larger chunks of words. We present preliminary ...
