Semantic Service Architectures for Smart Environments

Many industries and academic institutions share the vision that an appropriate use of information originated from the environment may add value to services in multiple domains and may help humans in dealing with the growing information overload which often seems to jeopardize our life. It is also clear that information sharing and mutual understanding between software agents may impact complex processes where many actors (humans and machines) are involved, leading to relevant socioeconomic benefits. Starting from these two input, architectural and technological solutions to enable “environment-related cooperative digital services” are here explored. The proposed analysis starts from the consideration that our environment is physical space and here diversity is a major value. On the other side diversity is detrimental to common technological solutions, and it is an obstacle to mutual understanding. An appropriate environment abstraction and a shared information model are needed to provide the required levels of interoperability in our heterogeneous habitat. This thesis reviews several approaches to support environment related applications and intends to demonstrate that smart-space-based, ontology-driven, information-sharing platforms may become a flexible and powerful solution to support interoperable services in virtually any domain and even in cross-domain scenarios. It also shows that semantic technologies can be fruitfully applied not only to represent application domain knowledge. For example semantic modeling of Human-Computer Interaction may support interaction interoperability and transformation of interaction primitives into actions, and the thesis shows how smart-space-based platforms driven by an interaction ontology may enable natural ad flexible ways of accessing resources and services, e.g, with gestures. An ontology for computational flow execution has also been built to represent abstract computation, with the goal of exploring new ways of scheduling computation flows with smart-space-based semantic platforms.

Semantic under-determinacy, Content and Context

The aim of the thesis is to investigate the topic of semantic under-determinacy, i.e. the failure of the semantic content of certain expressions to determine a truth-evaluable utterance content. In the first part of the thesis, I engage with the problem of setting apart semantic under-determinacy as opposed to other phenomena such as ambiguity, vagueness, indexicality. As I will argue, the feature that distinguishes semantic under-determinacy from these phenomena is its being explainable solely in terms of under-articulation. In the second part of the thesis, I discuss the topic of how communication is possible, despite the semantic under-determinacy of language. I discuss a number of answers that have been offered: (i) the Radical Contextualist explanation which emphasises the role of pragmatic processes in utterance comprehension; (ii) the Indexicalist explanation in terms of hidden syntactic positions; (iii) the Relativist account, which regards sentences as true or false relative to extra coordinates in the circumstances of evaluation (besides possible worlds). In the final chapter, I propose an account of the comprehension of utterances of semantically under-determined sentences in terms of conceptual constraints, i.e. ways of organising information which regulate thought and discourse on certain matters. Conceptual constraints help the hearer to work out the truth-conditions of an utterance of a semantically under-determined sentence. Their role is clearly semantic, in that they contribute to “what is said” (rather than to “what is implied”); however, they do not respond to any syntactic constraint. The view I propose therefore differs, on the one hand, from Radical Contextualism, because it stresses the role of semantic-governed processes as opposed to pragmatics-governed processes; on the other hand, it differs from Indexicalism in its not endorsing any commitment as to hidden syntactic positions; and it differs from Relativism in that it maintains a monadic notion if truth.

The Perception of American Adolescent Culture Through the Dubbing and Fansubbing of a Selection of US Teen Series from 1990 to 2013

The present dissertation aims at analyzing the construction of American adolescent culture through teen-targeted television series and the shift in perception that occurs as a consequence of the translation process. In light of the recent changes in television production and consumption modes, largely caused by new technologies, this project explores the evolution of Italian audiences, focusing on fansubbing (freely distributed amateur subtitles made by fans for fan consumption) and social viewing (the re-aggregation of television consumption based on social networks and dedicated platforms, rather than on physical presence). These phenomena are symptoms of a sort of ‘viewership 2.0’ and of a new type of active viewing, which calls for a revision of traditional AVT strategies. Using a framework that combines television studies, new media studies, and fandom studies with an approach to AVT based on Descriptive Translation Studies (Toury 1995), this dissertation analyzes the non-Anglophone audience’s growing need to participation in the global dialogue and appropriation process based on US scheduling and informed by the new paradigm of convergence culture, transmedia storytelling, and affective economics (Jenkins 2006 and 2007), as well as the constraints intrinsic to multimodal translation and the different types of linguistic and cultural adaptation performed through dubbing (which tends to be more domesticating; Venuti 1995) and fansubbing (typically more foreignizing). The study analyzes a selection of episodes from six of the most popular teen television series between 1990 and 2013, which has been divided into three ages based on the different modes of television consumption: top-down, pre-Internet consumption (Beverly Hills, 90210, 1990 – 2000), emergence of audience participation (Buffy the Vampire Slayer, 1997 – 2003; Dawson’s Creek, 1998 – 2003), age of convergence and Viewership 2.0 (Gossip Girl, 2007 – 2012; Glee, 2009 – present; The Big Bang Theory, 2007 - present).

Tradurre il multilinguismo al cinema: Lingue, identità culturali e loro rappresentazione sullo schermo

La presente ricerca ha un duplice obiettivo. Primo, individuare i modi in cui lingue e identità culturali diverse sono state rappresentate al cinema. Secondo, identificare le diverse strade imboccate dai professionisti del doppiaggio italiano quando si trovano a confrontarsi con un film in cui si parlano più lingue. La ricerca propone un approccio multidisciplinare che combina i contributi teorici sviluppati nel campo degli studi di traduzione audiovisiva con le modalità di analisi più comunemente utilizzate dalla semiotica del cinema. L'analisi si basa su un campione di 224 film multilingue prodotti dall'inizio degli anni Trenta alla fine degli anni Duemila. Particolare attenzione viene indirizzata al quadro teorico all'interno del quale viene interpretato il ruolo che il multilinguismo assume al cinema. Vengono identificate tre funzioni principali: conflitto, confusione e resa realistica. Un altro elemento chiave nell'analisi è costituito dal genere cinematografico prevalente a cui è possibile ricondurre ciascuno dei film selezionati. Sono individuati tre generi principali: il film drammatico, la commedia e il thriller. Nel film drammatico il multilinguismo agisce come un veicolo che produce e accentua il conflitto, mentre nella commedia esso di solito diventa un dispositivo comico che crea confusione e umorismo. Nel cinema thriller, invece, il multilinguismo funziona essenzialmente come un veicolo di suspense. Per quanto riguarda le soluzioni traduttive adottate nel doppiaggio italiano del cinema multilingue, sono rilevate tre macro-strategie: la conservazione, la neutralizzazione e la riduzione dell'originale dimensione multilingue. Ciascuna di queste tre strategie è passata a vaglio critico. Se nel primo caso si tratta di un tentativo di riprodurre fedelmente le originali situazioni multilingue rappresentate nel film, negli altri due casi si tratta di soluzioni che risentono fortemente delle specificità del doppiaggio come modalità di traduzione degli audiovisivi (fattori ideologici ed economici, nonché il problema tecnico dell'armonizzazione delle voci per i personaggi bilingue).
