Audiovisual materials and second-language acquisition: a comparison between native language subtitles and target language captions.

Over the last few years, the massive popularity of video streaming platforms has managed to impact our daily habits by making the watching of movies and TV shows one of the main activities of our free time. By providing a wide range of foreign language audiovisual content, these entertainment services may represent a powerful resource for language learners, as they provide them with the possibility to be exposed to authentic input. Moreover, research has shown the beneficial role of audiovisual textual aids such as native language subtitles and target language captions in enhancing language skills such as vocabulary and listening comprehension. The aim of this thesis is to analyze the existing literature on the subject of subtitled and captioned audiovisual materials used as a pedagogical tool for informal language learning.

Localizzazione e internazionalizzazione dei servizi di incrocio domanda/offerta di lavoro di Jopla S.r.l SB: tra traduzione umana e traduzione automatica

This thesis has been written as a result of the Language Toolkit project, organised by the Department of Interpreting and Translation of Forlì in collaboration with the Chamber of Commerce of Romagna. The aim of the project is to facilitate the internationalisation of small and medium enterprises in Romagna by making available to them the skills acquired by the students of the Faculty of Specialized Translation, who in turn are given the opportunity to approach an authentic professional context. Specifically, this thesis is the outcome of the 300-hour internship envisaged by the project, 75 of which were carried out at Jopla S.r.l. SB. The task assigned to the student was the translation into French of the Jopla For You web app and the Jopla PRO mobile app. This thesis consists of five chapters. The first chapter provides a general description of the Language Toolkit project and it focuses on the concept of translation into a non-native language. The second chapter outlines the theoretical context in which translation is set. Subsequently, the focus shifts to the topics of text, discourse, genre and textual typology, alongside a reflection on the applicability of these notions to web texts, and an analysis of the source text following Nord's model. The fourth chapter is dedicated to a description of the resources used in the preparation and translation phases. The fifth chapter describes the macro and micro strategies employed to carry out the translation. Furthermore, a comparative analysis between the human translation and the one provided by Google Translator is delivered. This analysis involves two methods: the first one follows the linguistic norms of the target language, while the second one relies on the error categorisation of the MQM model. Finally, the performance of Google Translate is investigated through the comparison of the results obtained from the MQM evaluation conducted in this thesis with the results obtained by Martellini (2021) in her analysis.

Bitext alignment: building and evaluating a bilingual corpus and translation memory of academic course descriptions

Following the internationalization of contemporary higher education, academic institutions based in non-English speaking countries are increasingly urged to produce contents in English to address international prospective students and personnel, as well as to increase their attractiveness. The demand for English translations in the institutional academic domain is consequently increasing at a rate exceeding the capacity of the translation profession. Resources for assisting non-native authors and translators in the production of appropriate texts in L2 are therefore required in order to help academic institutions and professionals streamline their translation workload. Some of these resources include: (i) parallel corpora to train machine translation systems and multilingual authoring tools; and (ii) translation memories for computer-aided tools. The purpose of this study is to create and evaluate reference resources like the ones mentioned in (i) and (ii) through the automatic sentence alignment of a large set of Italian and English as a Lingua Franca (ELF) institutional academic texts given as equivalent but not necessarily parallel (i.e. translated). In this framework, a set of aligning algorithms and alignment tools is examined in order to identify the most profitable one(s) in terms of accuracy and time- and cost-effectiveness. In order to determine the text pairs to align, a sample is selected according to document length similarity (characters) and subsequently evaluated in terms of extent of noisiness/parallelism, alignment accuracy and content leverageability. The results of these analyses serve as the basis for the creation of an aligned bilingual corpus of academic course descriptions, which is eventually used to create a translation memory in TMX format.

Implementation of a non ground meta interpreter for defeasible logic

Human reasoning is a fascinating and complex cognitive process that can be applied in different research areas such as philosophy, psychology, laws and financial. Unfortunately, developing supporting software (to those different areas) able to cope such as complex reasoning it’s difficult and requires a suitable logic abstract formalism. In this thesis we aim to develop a program, that has the job to evaluate a theory (a set of rules) w.r.t. a Goal, and provide some results such as “The Goal is derivable from the KB5 (of the theory)”. In order to achieve this goal we need to analyse different logics and choose the one that best meets our needs. In logic, usually, we try to determine if a given conclusion is logically implied by a set of assumptions T (theory). However, when we deal with programming logic we need an efficient algorithm in order to find such implications. In this work we use a logic rather similar to human logic. Indeed, human reasoning requires an extension of the first order logic able to reach a conclusion depending on not definitely true6 premises belonging to a incomplete set of knowledge. Thus, we implemented a defeasible logic7 framework able to manipulate defeasible rules. Defeasible logic is a non-monotonic logic designed for efficient defeasible reasoning by Nute (see Chapter 2). Those kind of applications are useful in laws area especially if they offer an implementation of an argumentation framework that provides a formal modelling of game. Roughly speaking, let the theory is the set of laws, a keyclaim is the conclusion that one of the party wants to prove (and the other one wants to defeat) and adding dynamic assertion of rules, namely, facts putted forward by the parties, then, we can play an argumentative challenge between two players and decide if the conclusion is provable or not depending on the different strategies performed by the players. Implementing a game model requires one more meta-interpreter able to evaluate the defeasible logic framework; indeed, according to Göedel theorem (see on page 127), we cannot evaluate the meaning of a language using the tools provided by the language itself, but we need a meta-language able to manipulate the object language8. Thus, rather than a simple meta-interpreter, we propose a Meta-level containing different Meta-evaluators. The former has been explained above, the second one is needed to perform the game model, and the last one will be used to change game execution and tree derivation strategies.

Engineering Concurrent and Event-driven Web Apps: An Agent-Oriented Approach based on the simpAL Language

Web is constantly evolving, thanks to the 2.0 transition, HTML5 new features and the coming of cloud-computing, the gap between Web and traditional desktop applications is tailing off. Web-apps are more and more widespread and bring several benefits compared to traditional ones. On the other hand reference technologies, JavaScript primarly, are not keeping pace, so a paradim shift is taking place in Web programming, and so many new languages and technologies are coming out. First objective of this thesis is to survey the reference and state-of-art technologies for client-side Web programming focusing in particular on what concerns concurrency and asynchronous programming. Taking into account the problems that affect existing technologies, we finally design simpAL-web, an innovative approach to tackle Web-apps development, based on the Agent-oriented programming abstraction and the simpAL language. == Versione in italiano: Il Web è in continua evoluzione, grazie alla transizione verso il 2.0, alle nuove funzionalità introdotte con HTML5 ed all’avvento del cloud-computing, il divario tra le applicazioni Web e quelle desktop tradizionali va assottigliandosi. Le Web-apps sono sempre più diffuse e presentano diversi vantaggi rispetto a quelle tradizionali. D’altra parte le tecnologie di riferimento, JavaScript in primis, non stanno tenendo il passo, motivo per cui la programmazione Web sta andando incontro ad un cambio di paradigma e nuovi linguaggi e tecnologie stanno spuntando sempre più numerosi. Primo obiettivo di questa tesi è di passare al vaglio le tecnologie di riferimento ed allo stato dell’arte per quel che riguarda la programmmazione Web client-side, porgendo particolare attenzione agli aspetti inerenti la concorrenza e la programmazione asincrona. Considerando i principali problemi di cui soffrono le attuali tecnologie passeremo infine alla progettazione di simpAL-web, un approccio innovativo con cui affrontare lo sviluppo di Web-apps basato sulla programmazione orientata agli Agenti e sul linguaggio simpAL.

Sviluppo di applicazioni mobile: confronto fra piattaforme native e tecnologie web utilizzando iOS e PhoneGap come caso di studio

Negli ultimi anni il mondo del mobile computing ha avuto una vera e propria crescita esponenziale grazie soprattutto all'entrata in scena dello smartphone. In realtà, per essere più precisi, è bene bene sottolineare che gli smartphone esistevano già da tempo ma il loro utilizzo era in particolar modo indirizzato ai professionisti per il quale era, ma continua ad essere tutt'oggi, un valido supporto in campo lavorativo, basti pensare all'importanza della comunicazione via e-mail e non solo. Seppur comunque fossero già presenti da tempo, i primi smartphone non godevano di certo di un touch-screen sofisticato come quello odierno nè in essi erano presenti funzionalità tipiche dei dispositivi che troviamo ad oggi sul mercato. Una svolta decisiva è stata segnata dall'introduzione dell'iPhone e successivamente dell'AppStore, grazie a questi la programmazione per i dispositivi mobile ha preso sempre più piede diventando un vero e proprio business. In un secondo momento alla programmazione nativa si affiancarono le tecnologie web. Questo mio lavoro di tesi si pone l'obiettivo di studiare in primis la struttura, caratteristiche e peculiarità del sistema operativo iOS e analizzare il framework PhoneGap al fine di riuscire a confrontarne i vari aspetti fondamentali anche attraverso lo sviluppo di piccole applicazioni. Così facendo, quindi scendendo nei dettagli di quelle che possono essere le differenze rilevanti, mi pongo l'obiettivo di valutarne relativi pro e contro al fine di fare una scelta del tutto personale tra iOS e PhoneGap.

Il child language brokering: Un case-study presso la scuola primaria G. Marconi e la scuola secondaria di I grado G. Diotti di casalmaggiore (CR).

Questa tesi presenta i risultati di un case-study condotto presso la scuola primaria G. Marconi e la scuola secondaria di I grado G. Diotti di Casalmaggiore (CR), volto ad indagare sul fenomeno della mediazione linguistica ad opera di bambini che, nel panorama moderno caratterizzato da una presenza straniera in continuo aumento, risulta una delle soluzioni più accessibili ai migranti per garantirsi un supporto linguistico che permetta l’accesso ai servizi pubblici fondamentali. La prima parte del testo costituisce un quadro teorico che consente di comprendere meglio gli obiettivi e i risultati dell’indagine condotta. Il primo capitolo si concentra sul rapporto immigrazione-scuola analizzando la situazione attuale, illustrando le caratteristiche e le esigenze della popolazione scolastica straniera ed esaminando le proposte ministeriali in materia di integrazione e accoglienza. Il secondo capitolo, invece, sposta l’attenzione sulla mediazione linguistica e culturale in Italia. Nello specifico viene dapprima approfondita la mediazione professionale facendo riferimento al quadro normativo e alle competenze specifiche del mediatore linguistico e culturale. In un secondo momento, viene introdotto il fenomeno della mediazione non professionale e viene illustrata la letteratura inerente. Da ultimo viene introdotto il tema del Child Language Brokering (CLB), ovvero il fenomeno della mediazione ad opera di minori. Partendo da una panoramica generale viene studiato lo sviluppo del CLB come oggetto di ricerca e ne vengono valutati aspetti positivi e negativi, soffermandosi in particolare sul contesto scolastico. Gli ultimi due capitoli, invece, sono dedicati alla parte operativa del lavoro di ricerca. Nel terzo capitolo viene presentato in maniera dettagliata il case-study analizzando la metodologia applicata, il campione selezionato e l’elaborazione dei questionari realizzati per la raccolta dei dati. Infine, nel quarto capitolo, sono esaminati i dati raccolti sul campo. Sulla base dei risultati ottenuti viene dapprima delineato il profilo del fenomeno in ciascuna delle scuole campione per poi mettere a confronto le tendenze generali emerse.
