Itzulpen automatikorako tresnen egokitzapena euskararako: post-edizioa, ebaluazioa eta aurre-edizioa

Proiektu honetan zehar Itzulpen Automatikoa eta horren inguruko tresnen inguruan jorratu da. Lengoaia Naturalaren Prozesamendua eta itzulpen automatikoa ikasi eta aztertu egin dira ikuspuntu zabal batetik. Itzulpen automatiko orokorraz eta horren aplikazio mota desberdinetatik gain, bestelako kontzeptuak ere tratatu dira, hala nola, itzulpenean laguntzeko tresnak, itzulpen automatikoaren ebaluazioa eta itzulpen automatikorako testuen aurre-edizioa eta post-edizioa. Ikasketa- eta aztertze-prozesu horretaz gain, erlazionatuta dauden tresnak erabili edota moldatu egin dira euskararako itzulpen automatikoan barne. Hiru atal nagusi nabarmendu daitezke: Lehenengo, OmegaT, itzulpenean laguntzeko softwarea, moldatu da Matxin euskararako itzultzaile automatikoa gehituz. Gainera, IXA Taldearen eta Euskal Wikipediaren arteko kolaborazio-lanean, Wikipediako artikuluak eskuratu, itzuli eta igotzeko aukera egokitu zaio OmegaT-ri eta horren erabilera sustatu da Euskal Wikipediako komunitatean eta UPV/EHUko Informatikako ikasle eta irakaslegoaren artean. Bestalde, lan honetaz baliatuz, OmegaT-k sortzen dituen itzulpen-memoriak, Matxin-en itzulpenen gaineko post-edizioan oinarrituak, eskuratzeko modu bat egin da, horiekin Matxin-en funtzionamendua hobetu ahal izateko. Ondoren, Asiya programan integratu egin da euskara. Asiya-k itzulpen automatikoaren ebaluazio eta meta-ebaluazioak egin ditzakeen aplikazioa da. Hainbat metrika aztertu dira euskara aztertzeko balio ote duten begiratzeko. Besteen artean, lau metrikari euskara gehitzeko saiakera egin nahi izan da IXA Taldeko euskarazko testuen analizatzaile batek eskainitako informazio sintaktikoa gehituz, baina bi metrika soilik egokitu ahal izan dira. Azkenik, DiSeg esaldi-segmentatzailea erabili egin da gaztelerazko corpus baten gainean esaldi luzeak banatzeko. Aurre-edizio hori eta gero itzuli egin dira eta Asiya erabiliz emaitzen ebaluazioa eta konparazioa egin dira, esaldi laburragoekin itzulpen automatiko eraginkorragoa lortzen oten den aztertzeko.

THE MODULATION PRINCIPLE OF VACUUM ON THE SUPERCONDUCTIVITY OF YBCO

By neutron diffraction and other experiments, we have found that oxygen ions in YBCO can diffuse out of the sample in vacuo at room and low temperature, while the T(c) decreases greatly. We have also found that if the vacuum-deoxidation process lasts for several days there will be a damping oscillation of T(c) with time (t), and higher vacuum corresponds to a greater amplitude and a shorter period. We tentatively think that T(c) should satisfy the following function: T(c0) is-proportional-to T(c)e(-betat)cos (omegat + phi); it may be due to the diffusion of oxygen and the saturation of the valence state.

Effective ac response in weakly nonlinear composites

The perturbation method is developed to deal with the problem of determining the effective nonlinear conductivity of Kerr-like nonlinear media under an external ac electric field. As an example, we have considered the cylindrical inclusion embedded in a host under the sinusoidal external field E-1 sin(omegat) + E-3 sin(3omegat) with frequencies omega and 3omega. The potentials of composites at higher harmonics are derived in both local inclusion particle and host regions. The effective responses of bulk nonlinear composites at basic frequency and harmonics are given for cylindrical composites in the dilute limit. Moreover, the relationships between the nonlinear effective responses at the basic frequency and the third harmonics are derived.

Effective dielectric response of nonlinear composites with external ac and dc electric field

The perturbation method is developed to investigate the effective nonlinear dielectric response of Kerr composites when the external ac and dc electric field is applied. Under the external ac and dc electric field E-app=E-a(1+sin omegat), the effective coupling nonlinear response can be induced by the cubic nonlinearity of Kerr nonlinear materials at the zero frequency, the finite basic frequency omega, the second and the third harmonics, 2omega and 3omega, and so on. As an example, we have investigated the cylindrical inclusions randomly embedded in a host and derived the formulas of the effective nonlinear dielectric response at harmonics in dilute limit. For a higher concentration of inclusions, we have proposed a nonlinear effective-medium approximation by introducing the general effective nonlinear response. With the relationships between the effective nonlinear response at harmonics and the general effective nonlinear response, we have derived a set of formulas of the effective nonlinear dielectric responses at harmonics for a larger volume fraction.

Traduzione tecnica e internazionalizzazione d'impresa: Il caso di Technologica S.r.l.

This dissertation is part of the Language Toolkit project which is a collaboration between the School of Foreign Languages and Literature, Interpreting and Translation of the University of Bologna, Forlì campus, and the Chamber of Commerce of Forlì-Cesena. This project aims to create an exchange between translation students and companies who want to pursue a process of internationalization. The purpose of this dissertation is demonstrating the benefits that translation systems can bring to businesses. In particular, it consists of the translation into English of documents supplied by the Italian company Technologica S.r.l. and the creation of linguistic resources that can be integrated into computer-assisted translation (CAT) software, in order to optimize the translation process. The latter is claimed to be a priority with respect to the actual translation products (the target texts), since the analysis conducted on the source texts highlighted that the company could streamline and optimize its English language communication thanks to the use of open source CAT tools such as OmegaT. The work consists of five chapters. The first introduces the Language Toolkit project, the company (Technologica S.r.l ) and its products. The second chapter provides some considerations about technical translation, its features and some misconceptions about it. The difference between technical translation and scientific translation is then clarified and an overview is offered of translation aids such as those used for computer-assisted translation, machine translation, termbases and translation memories. The third chapter contains the analysis of the texts commissioned by Technologica S.r.l. and their categorization. The fourth chapter describes the translation process, with particular attention to terminology extraction and the creation of a bilingual glossary based on a specialized corpus. The glossary was integrated into the OmegaT software in order to facilitate the translation process both for the present task and for future applications. The memory deriving from the translation represents a sort of hybrid resource between a translation memory and a glossary. This was found to be the most appropriate format, given the specific nature of the texts to be translated. Finally, in chapter five conclusions are offered about the importance of language training within a company environment, the potentialities of translation aids and the benefits that they would bring to a company wishing to internationalize itself.

Revisione, Localizzazione e Traduzione del materiale dell'azienda Graziani Packaging

Il presente lavoro di tesi s’inserisce all’interno del progetto Language Toolkit, nato dalla collaborazione tra la Camera di Commercio di Forlì-Cesena e la Scuola di Lingue e Letterature, Traduzione e Interpretazione di Forlì, al fine di avvicinare il mondo dell’università al mondo del lavoro. In particolare, la tesi è frutto della collaborazione tra la laureanda e la Graziani Packaging, azienda italiana leader nel settore del packaging ortofrutticolo e industriale, e consiste nella revisione di una brochure, nella localizzazione del sito web www.graziani.com e nella traduzione di una presentazione PowerPoint, il tutto dall’italiano al tedesco. Il lavoro si compone di tre capitoli. Nel primo, che rappresenta un approfondimento teorico sul tema della localizzazione, si analizza nel dettaglio l’acronimo GILT, si espongono brevemente le tappe principali che hanno caratterizzato la nascita e lo sviluppo del settore della localizzazione e si esaminano le caratteristiche linguistiche, culturali e tecniche della localizzazione di siti web. Il secondo capitolo è dedicato al concetto di qualità in ambito traduttivo e al tema della revisione. In particolare, nella prima parte si analizzano gli standard di qualità professionali, i criteri di qualità proposti da Scarpa (2008) e la classificazione degli errori di traduzione sviluppata da Mossop (2001), mentre l’ultima parte riguarda il processo di revisione in concreto. Nel terzo capitolo, infine, vengono analizzati i tre testi di partenza forniti dall’azienda al traduttore (brochure, sito web e presentazione PowerPoint), e viene esposto e commentato il lavoro di revisione, localizzazione e traduzione degli stessi, ponendo una particolare enfasi sugli aspetti linguistici, culturali e tecnici più interessanti che lo hanno caratterizzato. La tesi si chiude con un glossario terminologico contenente i termini chiave, in italiano e in tedesco, relativi al dominio del packaging ortofrutticolo e industriale, individuati nel corso del lavoro di revisione, localizzazione e traduzione.
