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.

Dopo una breve introduzione sulla realtà aumentata (definizione, storia e stato dell’arte) viene effettuata un'analisi delle librerie esistenti per l’implementazione su dispositivi mobile. Considerando compatibilità con i recenti SO, frequenza degli aggiornamenti, costi per le licenze e funzionalità offerte viene scelta la libreria Vuforia, originariamente sviluppata da Qualcomm e poi acquistata da PTC inc. Si conviene poi che le apps basate su realtà aumentata creano il contenuto “aumentato” in due maniere: o tramite riconoscimento di una specifica immagine oppure tramite localizzazione GPS. Di questi due metodi descritti, il primo risulta molto più affidabile e per questo viene sviluppata una app che crea un contenuto in 3D (aumentato) riconoscendo una immagine: funzionalità di Image Targeting. Il progetto considera le seguenti varianti: l’immagine da riconoscere, chiamata “target”, può essere in un database locale oppure cloud mentre il contenuto in 3D aumentato può essere sia statico che animato. Durante la fase di implementazione vengono fornite anche alcuni nozioni di base di Computer Graphic per il rendering del modello 3D. La tesi si conclude con una panoramica di apps presenti sullo store che funzionano secondo questo principio di Image Targeting, i possibili utilizzi in ambito educativo/ludico ed i costi di realizzazione.

The digital revolution has affected all aspects of human life, and interpreting is no exception. This study will provide an overview of the technology tools available to the interpreter, but it will focus more on simultaneous interpretation, particularly on the “simultaneous interpretation with text” method. The decision to analyse this particular method arose after a two-day experience at the Court of Justice of the European Union (CJEU), during research for my previous Master’s dissertation. During those days, I noticed that interpreters were using "simultaneous interpretation with text" on a daily basis. Owing to the efforts and processes this method entails, this dissertation will aim at discovering whether technology can help interpreters, and if so, how. The first part of the study will describe the “simultaneous with text” approach, and how it is used at the CJEU; the data provided by a survey for professional interpreters will describe its use in other interpreting situations. The study will then describe Computer-Assisted Language Learning technologies (CALL) and technologies for interpreters. The second part of the study will focus on the interpreting booth, which represents the first application of the technology in the interpreting field, as well as on the technologies that can be used inside the booth: programs, tablets and apps. The dissertation will then analyse the programs which might best help the interpreter in "simultaneous with text" mode, before providing some proposals for further software upgrades. In order to give a practical description of the possible upgrades, the domain of “judicial cooperation in criminal matters” will be taken as an example. Finally, after a brief overview of other applications of technology in the interpreting field (i.e. videoconferencing, remote interpreting), the conclusions will summarize the results provided by the study and offer some final reflections on the teaching of interpreting.

This work focuses on Machine Translation (MT) and Speech-to-Speech Translation, two emerging technologies that allow users to automatically translate written and spoken texts. The first part of this work provides a theoretical framework for the evaluation of Google Translate and Microsoft Translator, which is at the core of this study. Chapter one focuses on Machine Translation, providing a definition of this technology and glimpses of its history. In this chapter we will also learn how MT works, who uses it, for what purpose, what its pros and cons are, and how machine translation quality can be defined and assessed. Chapter two deals with Speech-to-Speech Translation by focusing on its history, characteristics and operation, potential uses and limits deriving from the intrinsic difficulty of translating spoken language. After describing the future prospects for SST, the final part of this chapter focuses on the quality assessment of Speech-to-Speech Translation applications. The last part of this dissertation describes the evaluation test carried out on Google Translate and Microsoft Translator, two mobile translation apps also providing a Speech-to-Speech Translation service. Chapter three illustrates the objectives, the research questions, the participants, the methodology and the elaboration of the questionnaires used to collect data. The collected data and the results of the evaluation of the automatic speech recognition subsystem and the language translation subsystem are presented in chapter four and finally analysed and compared in chapter five, which provides a general description of the performance of the evaluated apps and possible explanations for each set of results. In the final part of this work suggestions are made for future research and reflections on the usability and usefulness of the evaluated translation apps are provided.
