Costituzione di un corpus giuridico parallelo italiano-arabo
Get PDFI corpora paralleli rappresentano un'importanza assoluta per tante applicazioni della linguistica computazionale, come la traduzione automatica, l'estrazione delle terminologie, o la disambiguazione semantica, ecc. In questo lavoro presentiamo il nostro tentativo di creare un corpus giuridico parallelo italiano-arabo allineato a livello di frase e annotato a livello morfosintattico
Le variazioni terminologiche in un corpus giuridico parallelo italiano-arabo: studio linguistico-computazionale
Get PDFLa presente tesi si pone l’obiettivo di studiare le variazioni terminologiche in un corpus giuridico parallelo italiano-arabo, adottando un approccio linguistico-computazionale. La tesi parte dall’assunto che anche i linguaggi specialistici presentano delle variazioni a livello lessicale come è il caso della lingua comune, contrastando quindi con la teoria generale della terminologia basata sul principio di monosemia e univocità secondo il quale i termini, al fine di evitare qualsiasi ambiguità comunicativa, non devono subire delle variazioni.
Nel lavoro la componente linguistica si integra con i metodi statistici: mentre la parte linguistica si evidenzia nei capitoli riguardanti la variazione nei discorsi specializzati, i procedimenti di formazione delle parole in italiano e in arabo e l’analisi delle variazioni estratte dal corpus parallelo, le misure statistiche vengono adoperate, oltre che nella creazione e nell’annotazione del corpus parallelo, nell'estrazione, sia monolingue che bilingue, dei termini dal corpus e nell'individuazione delle variazioni terminologiche
Italian-Arabic domain terminology extraction from parallel corpora
Get PDFIn this paper we present our approach to extract multi-word terms (MWTs) from an Italian-Arabic parallel corpus of legal texts. Our approach is a hybrid model which combines linguistic and statistical knowledge. The linguistic approach includes Part Of Speech (POS) tagging of the corpus texts in the two languages in order to formulate syntactic patterns to identify candidate terms. After that, the candidate terms will be ranked by statistical association measures which here represent the statistical knowledge. After the creation of two MWTs lists, one for each language, the parallel corpus will be used to validate and identify translation equivalents
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
