Towards Syntactic Iberian Polarity Classification

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 dependent and require adaptation, especially in multilingual scenarios. We tackle this challenge in the context of the Iberian Peninsula, releasing the first symbolic syntax-based Iberian system with rules shared across five official languages: Basque, Catalan, Galician, Portuguese and Spanish. The model is made available.Comment: 7 pages, 5 tables. Contribution to the 8th Workshop on Computational Approaches to Subjectivity, Sentiment and Social Media Analysis (WASSA-2017) at EMNLP 201

Domain adaptation strategies in statistical machine translation: a brief overview

© Cambridge University Press, 2015.Statistical machine translation (SMT) is gaining interest given that it can easily be adapted to any pair of languages. One of the main challenges in SMT is domain adaptation because the performance in translation drops when testing conditions deviate from training conditions. Many research works are arising to face this challenge. Research is focused on trying to exploit all kinds of material, if available. This paper provides an overview of research, which copes with the domain adaptation challenge in SMT.Peer ReviewedPostprint (author's final draft

Bilingual newsgroups in Catalonia: a challenge for machine translation

This paper presents a linguistic analysis of a corpus of messages written in Catalan and Spanish, which come from several informal newsgroups on the Universitat Oberta de Catalunya (Open University of Catalonia; henceforth, UOC) Virtual Campus. The surrounding environment is one of extensive bilingualism and contact between Spanish and Catalan. The study was carried out as part of the INTERLINGUA project conducted by the UOC's Internet Interdisciplinary Institute (IN3). Its main goal is to ascertain the linguistic characteristics of the e-mail register in the newsgroups in order to assess their implications for the creation of an online machine translation environment. The results shed empirical light on the relevance of characteristics of the e-mail register, the impact of language contact and interference, and their implications for the use of machine translation for CMC data in order to facilitate cross-linguistic communication on the Internet

Why Catalan-Spanish Neural Machine Translation? Analysis, comparison and combination with standard Rule and Phrase-based technologies

Catalan and Spanish are two related languages given that both derive from Latin. They share similarities in several linguistic levels including morphology, syntax and semantics. This makes them particularly interesting for the MT task. Given the recent appearance and popularity of neural MT, this paper analyzes the performance of this new approach compared to the well-established rule-based and phrase-based MT systems. Experiments are reported on a large database of 180 million words. Results, in terms of standard automatic measures, show that neural MT clearly outperforms the rule-based and phrase-based MT system on in-domain test set, but it is worst in the out-of-domain test set. A naive system combination specially works for the latter. In-domain manual analysis shows that neural MT tends to improve both adequacy and fluency, for example, by being able to generate more natural translations instead of literal ones, choosing to the adequate target word when the source word has several translations and improving gender agreement. However, out-of-domain manual analysis shows how neural MT is more affected by unknown words or contexts.Postprint (published version

Linguistic commodification in tourism

Drawing on fieldwork conducted between 2002 and 2012 in Switzerland, Catalunya and different zones of francophone Canada in sites related to heritage and cultural tourism, we argue that tourism, especially i n multilingual peripheries, is a key site for a sociolinguistic exploration of the political economy of globalization. We link shifts in the role of language in tourism to shifts in phases of capitalism, focusing on the shift from industrial to late capitalism, and in particular on the effects of the commodification of authenticity. We examine the tensions this shift generates in ideologies and practices of language, concerned especially with defining the nature of the tourism product, the public and the management of the tourism process. This results in an as yet unresolved destabilization of hitherto hegemonic discourses linking languages to cultures, identities, nations and States

The Role of Public Service Broadcasters in the Era of Convergence A Case Study of Televisió de Catalunya

The development of the convergence process has several implications in the reconfiguration of the media landscape. Public services broadcasters have new opportunities to fulfil their public service duties in a new competitive environment, which involves developing new applications on new platforms. Televisió de Catalunya, the public service broadcaster (PSB) of Catalonia, has developed a clear strategy in this new convergent environment, applying its traditional know-how to new interactive and digital media according to its public mission and getting positive feedback.convergence; public service broadcasting; interactive TV; bandwidth; 3G services; multimedia and digital divide

Lipdubs as an Instrument to Overcome Invisibility in the Mass-Media. A study of four enthusiastic cases recorded in Quebec, USA, Catalonia and the Basque Country

This paper summarizes the principal conclusions of an investigation into lipdub as an instrument used by social movements in order to get more social influence. Since its creation in 2006, the phenomenon of lipdubs has increased\ud considerably. This research presents an analytical model for this type of video, providing general data, figures about the number of participants, characteristics of the song used and information about the profile of the audience. The work\ud highlights the main hypothetical features and components of a good lipdub. Four videos with high impact on Youtube are analyzed. This work claims that, at this time, a good lipdub can be a crucial tool for social movements in order to\ud overcome the invisibility with which the mass-media often punishes any expression which challenges mainstream tendencies
