UHD: cross-lingual word sense disambiguation using multilingual co-occurrence graphs

Silberer, Carina; Ponzetto, Simone Paolo (ACL (Association for Computational Linguistics), 2010)

We describe the University of Heidelberg (UHD) system for the Cross-LingualWord Sense Disambiguation SemEval-2010 task (CL-WSD). The system performs CLWSD by applying graph algorithms previously developed for monolingual ...
Unnatural language processing: how do language models handle machine-generated prompts?

Kervadec, Corentin; Franzon, Francesca; Baroni, Marco (ACL (Association for Computational Linguistics), 2023)

Language model prompt optimization research has shown that semantically and grammatically well-formed manually crafted prompts are routinely outperformed by automatically generated token sequences with no apparent meaning ...
UPF-cobalt submission to WMT15 metrics task

Fomicheva, Marina; Bel Rafecas, Núria; da Cunha Fanego, Iria; Malinovskiy, Anton (ACL (Association for Computational Linguistics), 2015)

An important limitation of automatic evaluation metrics is that, when comparing Machine Translation (MT) to a human reference, they are often unable to discriminate between acceptable variation and the differences that are ...
Using language resources in humanities research

Villegas, Marta; Bel Rafecas, Núria; Gonzalo Penela, Carlos; Moreno, Amparo; Simelio, Núria (ACL (Association for Computational Linguistics), 2012)

In this paper we present two real cases, in the fields of discourse analysis of newspapers and communication research which demonstrate the impact of Language Resources (LR) and NLP in the humanities. We describe our ...
Using qualia information to identify lexical semantic classes in an unsupervised clustering task

Romeo, Lauren; Mendes, Sara; Bel Rafecas, Núria (ACL (Association for Computational Linguistics), 2012)

Acquiring lexical information is a complex problem, typically approached by relying on a number of contexts to contribute information for classification. One of the first issues to address in this domain is the determination ...
Using unmarked contexts in nominal lexical semantic classification

Romeo, Lauren; Mendes, Sara; Bel Rafecas, Núria (Association for Computational Linguistics (ACL), 2014)

The work presented here addresses the use of unmarked contexts in pattern-based nominal lexical semantic classification. We define unmarked contexts to be the counterposition of the class-indicatory, or marked, contexts. ...
VP ellipsis without indices

Hunter, Julie; Hardt, Daniel; Asher, Nicholas (Cornell University, Linguistic Society of America, 2013)

This paper compares two views on the status of indices in syntactic and logical representations. On a structural view, indices are syntactic formants on a par with node labels and phrase bracketings, and are thus a part ...
Web Services for Bayesian Learning

Padró, Muntsa; Bel Rafecas, Núria (ACL (Association for Computational Linguistics), 2012)

In this demonstration we present our web services to perform Bayesian learning for classification tasks.
What do entity-centric models learn? Insights from entity linking in multi-party dialogue

Boleda, Gemma; Aina, Laura; Silberer, Carina; Sorodoc, Ionut-Teodor; Westera, Matthijs (ACL (Association for Computational Linguistics), 2019)

Humans use language to refer to entities in the external world. Motivated by this, in recent years several models that incorporate a bias towards learning entity representations have been proposed. Such entity-centric ...
What you can cram into a single $&!#* vector: probing sentence embeddings for linguistic properties

Conneau, Alexis; Kruszewski, German; Lample, Guillaume; Barrault, Loïc; Baroni, Marco (ACL (Association for Computational Linguistics), 2018)

Although much effort has recently been devoted to training high-quality sentence embeddings, we still have a poor understanding of what they are capturing. “Downstream” tasks, often based on sentence classification, are ...
When wide scope is not enough: scope and topicality of discourse referents

Barberà, Gemma (Springer, 2011)

This paper analyses the semantic attributes discourse referents in Catalan Sign Language may have in order to have a corresponding location established in sign space. It is argued that a combination of scope and topicality ...
Young children's sensitivity to polite stance expressed through audiovisual prosody in requests

Hübscher, Iris; Prieto Vives, Pilar, 1965-; Wagner, Laura (International Speech Communication Association, 2016)

While children’s acquisition of lexically encoded politeness formulas has been investigated to a certain extent, little is known about their sensitivity to prosody and facial expressions as cues to politeness. The goal of ...
