Semi-automatic Filtering of Translation Errors in Triangle Corpus

The meaning that Justice has after a conflict in a society might vary regarding the political development and cultural and shared values of a certain society. Rawls, in his Theory of Justice gives his idea of what justice is and presents two principles of justice that he argues are required to live in a good society: a first principle that secures equal rights and liberties for all individuals and a second egalitarian principle that restrains the consequences of economic inequalities within societies. He also introduces the concept of “overlapping consensus” which I will use regarding the idea of Reconciliation, at the end of this paper. In the cases presented in this paper (i.e. Argentina and South Africa), essential human rights were violated, therefore wrongdoers made the society unjust. The aim of this thesis is to elucidate the conditions that are necessary to re-establish justice when a society goes through a conflict. I will introduce some ideas concerning that issue: ideas of retribution, reparation and reconciliation. These are seen as different paths for several countries when trying to tackle to the matter of achieving justice. In my view, this question can be answered appealing first to an intuitive conception of moral justice that may exist at an individual and collective level, as well. The ethical dilemmas both levels have are in relation to the harm done, punishments and how to balance them, limiting, for instance, the punishment in order to accomplish a just and a better society. I will also present how shared values can result from a process of reconciliation, which is considered as the ideal alternative to achieve justice. However, when the equilibrium between members of a community is broken, some people claim that punishment can restore that lost equilibrium that existed before in the community. Nevertheless, peace, reconciliation and justice cannot be constructed under the basis of silence. One way to keep memory alive is to let survivors, for instance, narrate what they have lived through; telling stories also creates a new space to share with others their experiences, revealing their fears and emotions. Regarding this theme, I will present the NUNCA MAS (Never Again) report, which is fundamental as it gives some testimonies, facts and proposals that will help to reach a consensus and therefore, future reconciliations. Why is important to achieve justice? Because then members of a certain community will be able to interact in the present with common shared values and thus, deal with the past. Not to consider reconciliation as one important step to achieve justice, and only think in terms of punishment, instead of giving way to peace and justice, could perhaps promote the possibility of further conflicts. To consider both punishment and reconciliation might just be one possible blueprint in the long and difficult way of searching for a just society

A Sub-Character Architecture for Korean Language Processing

We introduce a novel sub-character architecture that exploits a unique compositional structure of the Korean language. Our method decomposes each character into a small set of primitive phonetic units called jamo letters from which character- and word-level representations are induced. The jamo letters divulge syntactic and semantic information that is difficult to access with conventional character-level units. They greatly alleviate the data sparsity problem, reducing the observation space to 1.6% of the original while increasing accuracy in our experiments. We apply our architecture to dependency parsing and achieve dramatic improvement over strong lexical baselines.Comment: EMNLP 201

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

What can we learn from Semantic Tagging?

We investigate the effects of multi-task learning using the recently introduced task of semantic tagging. We employ semantic tagging as an auxiliary task for three different NLP tasks: part-of-speech tagging, Universal Dependency parsing, and Natural Language Inference. We compare full neural network sharing, partial neural network sharing, and what we term the learning what to share setting where negative transfer between tasks is less likely. Our findings show considerable improvements for all tasks, particularly in the learning what to share setting, which shows consistent gains across all tasks.Comment: 9 pages with references and appendixes.

Predicting Native Language from Gaze

A fundamental question in language learning concerns the role of a speaker's first language in second language acquisition. We present a novel methodology for studying this question: analysis of eye-movement patterns in second language reading of free-form text. Using this methodology, we demonstrate for the first time that the native language of English learners can be predicted from their gaze fixations when reading English. We provide analysis of classifier uncertainty and learned features, which indicates that differences in English reading are likely to be rooted in linguistic divergences across native languages. The presented framework complements production studies and offers new ground for advancing research on multilingualism.Comment: ACL 201
