Digging into signs: Developing standard annotation practices for cross-linguistic, quantitative analysis of sign language data. Final Report.

For sign languages used by deaf communities, linguistic corpora have until recently been unavailable, due to the lack of a writing system and a written culture in these communities, and the very recent advent of digital video. Recent improvements in video and computer technology have now made larger sign language datasets possible; however, large sign language datasets that are fully machine-readable are still elusive. This is due to two challenges. 1. Inconsistencies that arise when signs are annotated by means of spoken/written language. 2. The fact that many parts of signed interaction are not necessarily fully composed of lexical signs (equivalent of words), instead consisting of constructions that are less conventionalised. As sign language corpus building progresses, the potential for some standards in annotation is beginning to emerge. But before this project, there were no attempts to standardise these practices across corpora, which is required to be able to compare data crosslinguistically. This project thus had the following aims: 1. To develop annotation standards for glosses (lexical/word level) 2. To test their reliability and validity 3. To improve current software tools that facilitate a reliable workflow Overall the project aimed not only to set a standard for the whole field of sign language studies throughout the world but also to make significant advances toward two of the world’s largest machine-readable datasets for sign languages – specifically the BSL Corpus (British Sign Language, http://bslcorpusproject.org) and the Corpus NGT (Sign Language of the Netherlands, http://www.ru.nl/corpusngt).

Word frequency cues word order in adults: cross-linguistic evidence

[EN] One universal feature of human languages is the division between grammatical functors and content words. From a learnability point of view, functors might provide entry points or anchors into the syntactic structure of utterances due to their high frequency. Despite its potentially universal scope, this hypothesis has not yet been tested on typologically different languages and on populations of different ages. Here we report a corpus study and an artificial grammar learning experiment testing the anchoring hypothesis in Basque, Japanese, French, and Italian adults. We show that adults are sensitive to the distribution of functors in their native language and use them when learning new linguistic material. However, compared to infants’ performance on a similar task, adults exhibit a slightly different behavior, matching the frequency distributions of their native language more closely than infants do. This finding bears on the issue of the continuity of language learning mechanism.

Four essays on the empirical analysis of political ideology

This thesis examines four distinct facets and methods for understanding political ideology, and so it includes four distinct chapters with only moderate connections between them. Chapter 2 examines how reactions to emotional stimuli vary with political opinion, and how the stimuli can produce changes in an individuals political preferences. Chapter 3 examines the connection between self-reported fear and item nonresponse on surveys. Chapter 4 examines the connection between political and moral consistency with low-dimensional ideology, and Chapter 5 develops a technique for estimating ideal points and salience in a low-dimensional ideological space.

A norma gramatical como objeto de análise e de ensino: reflexões contemporâneas

Normas linguísticas são os usos instituídos pelos falantes da língua. Há normas consagradas pela tradição literária, por exemplo, e há normas consagradas pela tradição das comunidades. Quando estas não são aceitas, pode se dar o conflito, motivado pela não aceitação da nova norma, ou da norma diferente, geralmente acompanhada de avaliações negativas. Tomando os pronomes pessoais ele/lhe acusativos, me inicial e se sujeito (usando outras categorias quando a situação for favorável) como referência, procura-se investigar os motivos que levam a tais conflitos. Usa-se um conjunto de pensamentos provenientes da sociolinguística, do funcionalismo, da linguística histórica, da tradição gramatical, que, juntos, dão sustentação à problemática, sem levantar corpus exaustivo para descrição e explicação de regras da língua, motivo por que essas teorias são aproveitadas, enfaticamente, apenas em suas bases teóricas gerais. Os exemplos são esparsamente colhidos em fontes diversas: livros, canções, textos literários, ensaios, mas principalmente em notícias veiculadas na internet. É o que basta para um exame crítico da questão abordada. Para tanto, foram cotejados os posicionamentos da normatividade (a língua ideal, homogênea) com os da normalidade (a língua em uso, heterogênea). No entrementes é que estão as causas dos conflitos: a ideia de que a escrita representa o modelo certo, a resistência às mudanças e variações, o imaginário social que decide o certo e o errado, a ideologia avessa à evolução da língua e os conselhos do tipo não use e evite vão desgastando a concepção de língua. Para posturas como essas, não são aceitos os usos estigmatizados, embora abundantemente usados nos veículos de comunicação sociais

Aula de leitura: um jogo de restrição dos sentidos

O objetivo principal desta pesquisa é analisar os procedimentos didáticos relativos à leitura, no livro didático, Português Contexto, Interlocução e Sentido, destinado ao Ensino Médio, da Editora Moderna, de autoria de Maria Luiza M. Abaurre, Maria Bernadete M. Abaurre e Marcela Pontara, em sua seção de Produção de Texto, principalmente. A análise visa configurar o percurso teórico-metodológico desse livro didático, com o intuito de observar em que consiste a abordagem discursiva de leitura pretendida por esse livro. Para tanto, busquei contrapor os conceitos e procedimentos desenvolvidos no livro didático com aquilo que, em Análise do Discurso, se concebe como uma abordagem discursiva de leitura. Parto do princípio de que uma abordagem discursiva de leitura pressupõe a consideração das condições de produção de um texto, isto é, a relação de posições histórica e socialmente determinadas em que o simbólico (linguístico) e o imaginário (ideológico) se juntam (ORLANDI, 2008, p.11). A análise do corpus demonstrou que, a despeito de anunciar uma abordagem discursiva, o livro didático não realiza esse intento. As propostas didáticas de leitura repetem o tradicional modelo de interpretação de texto, sem considerar os pressupostos elementares de uma análise discursiva, isto é, que o sentido não está inscrito na superficialidade do texto, mas é produto da complexa relação entre leitor, autor e contexto sócio-histórico-ideológico

A rhetorical approach to IT diffusion: reconceptualizing the ideology-framing relationship in computerization movements

In this paper we propose rhetoric as a valuable yet underdeveloped alternative paradigm for examining IT diffusion. Building on recent developments of computerization movements theory, our rhetorical approach proposes that two central elements of the theory, framing and ideology, rather than being treated as separate can be usefully integrated. We suggest that IT diffusion can be usefully explored through examining the interrelationship of the deep structures underlying ideology and the type and sequence of rhetorical claims underpinning actors’ framing strategies. Our theoretical developments also allow us to better understand competing discourses influencing the diffusion process. These discourses reflect the ideologies and shape the framing strategies of actors in the broader field context. We illuminate our theoretical approach by drawing on the history of the diffusion of free and open source software.

Phrase linguistic classification and generalization for improving statistical machine translation

In this paper a method to incorporate linguistic information regarding single-word and compound verbs is proposed, as a first step towards an SMT model based on linguistically-classified phrases. By substituting these verb structures by the base form of the head verb, we achieve a better statistical word alignment performance, and are able to better estimate the translation model and generalize to unseen verb forms during translation. Preliminary experiments for the English - Spanish language pair are performed, and future research lines are detailed. © 2005 Association for Computational Linguistics.

An ambiguity-based theory of the linguistic verbal joke in English

Instytut Filologii Angielskiej

Exploitation of linguistic ambiguity in Polish and English jokes

English & Polish jokes based on linguistic ambiguity are constrasted. Linguistic ambiguity results from a multiplicity of semantic interpretations motivated by structural pattern. The meanings can be "translated" either by variations of the corresponding minimal strings or by specifying the type & extent of modification needed between the two interpretations. C. F. Hockett's (1972) translatability notion that a joke is linguistic if it cannot readily be translated into other languages without losing its humor is used to interpret some cross-linguistic jokes. It is claimed that additional intralinguistic criteria are needed to classify jokes. By using a syntactic representation, the humor can be explained & compared cross-linguistically. Since the mapping of semantic values onto lexical units is highly language specific, translatability is much less frequent with lexical ambiguity. Similarly, phonological jokes are not usually translatable. Pragmatic ambiguity can be translated on the basis of H. P. Grice's (1975) cooperative principle of conversation that calls for discourse interpretations. If the distinction between linguistic & nonlinguistic jokes is based on translatability, pragmatic jokes must be excluded from the classification. Because of their universality, pragmatic jokes should be included into the linguistic classification by going beyond the translatability criteria & using intralinguistic features to describe them.
