    • Cloud Strife: Expanding the horizons of Cloud Gaming Services 

      O'MAHONY, DONAL; Doyle, Joseph; Islam, Syed; Bashroush, Rabih (2017)
      Cloud gaming where computer games are executed on cloud based resources is a new service which can be extremely challenging for service providers. Unlike other web and video streaming applications it requires both a ...

    • Measuring Synchrony in Task-based Dialogues 

      VOGEL, CARL; Reverdy, Justine (ISCA, 2017)
      In many contexts from casual everyday conversations to formal discussions, people tend to repeat their interlocutors, and themselves. This phenomenon not only yields random repetitions one might expect from a natural Zipfian ...

    • Class-specific Object Pose Estimation and Reconstruction using 3D Part Geometry 

      PRASAD, MUKTA; Kumar, Arun C.S.; Bódis-Szomorú, András; Bhandarkar, Suchendra (2016)
      We propose a novel approach for detecting and reconstructing class-specific objects from 2D images. Reconstruction and detection, despite major advances, are still wanting in performance. Hence, approaches that try to solve ...

    • The Future of E-Voting 

      Tewari, Hitesh; Tarasov, Pavel (2017)
      Voting systems have been around for hundreds of years and despite different views on their integrity, have always been deemed secure with some fundamental security and anonymity principles. Numerous electronic ...

    • SAMoD: Shared Autonomous Mobility-on-Demand using Decentralized Reinforcement Learning 

      Dusparic, Ivana; Guériau, Maxime (2018)
      Shared mobility-on-demand systems can improve the efficiency of urban mobility through reduced vehicle ownership and parking demand. However, some issues in their implementations remain open, most notably the issue of ...

    • On-Talk and Off-Talk Detection: A Discrete Wavelet Transform Analysis of Electroencephalogram 

      HAIDER, FASIH; AKIRA, HAYAKAWA; LUZ, SATURNINO; VOGEL, CARL; CAMPBELL, NICK (2018)
      Spoken interaction with a machine results in a behaviour that is not very common in face-to-face human communication: Off-Talk, which is defined as speech utterances that are not directed to an immediate interlocutor, the ...

    • Speech Rate Calculations with Short Utterances: A Study from a Speech-to-Speech, Machine Translation Mediated Map Task 

      AKIRA, HAYAKAWA; VOGEL, CARL; LUZ, SATURNINO; CAMPBELL, NICK (European Language Resources Association (ELRA), 2018)
      The motivation for this paper is to present a way to verify if an utterance within a corpus is pronounced at a fast or slow pace. An alternative method to the well-known Word-Per-Minute (wpm) method for cases where this ...

    • Exploring Linked Data For The Automatic Enrichment of Historical Archives 

      PANDIT, HARSHVARDHAN JITENDRA; Munnelly, Gary; Lawless, Seamus (2018)
      With the increasing scale of online cultural heritage collections, the efforts of manually adding annotations to their contents become a challenging and costly endeavour. Entity Linking is a process used to automatically ...

    • Towards Knowledge-based Systems for GDPR Compliance 

      O'Sullivan, Declan; Lewis, David; PANDIT, HARSHVARDHAN JITENDRA (2018)
      Legal compliance is traditionally seen to be sufficiently demonstrable using legal documents that describe how various operations and activities follow a given set of obligations. The General Data Protection Regulation ...

    • Using Ontology Design Patterns to Define SHACL Shapes 

      O'Sullivan, Declan; Lewis, David; PANDIT, HARSHVARDHAN JITENDRA (CEUR-WS, 2018)
      SHACL shapes used for validation are not related to the axioms used in ontologies used to define the instances. One of the issues with using such axioms is their dependence on concepts which may not be used within the ...

    • Investigating Conditional Data Value Under GDPR 

      O'Sullivan, Declan; Lewis, David; PANDIT, HARSHVARDHAN JITENDRA; Petkov, Plamen (Science Direct, 2018)
      The calculation of data value is based on the assumption of continued presence of information. When the data in consideration concerns personal information, laws such as the European General Data Protection Regulation ...

    • Explaining Disclosure Decisions Over Personal Data 

      O'Sullivan, Declan; PANDIT, HARSHVARDHAN JITENDRA; Gachpaz Hamed, Roghaiyeh (Ramisa); Conlan, Owen (CEUR WS, 2019)
      The use of automated decision making systems to disclose personal data provokes privacy concerns as it is difficult for individuals to understand how and why these decisions are made. This research proposes an approach ...

    • An Exploration of Data Interoperability for GDPR 

      O'Sullivan, Declan; Lewis, David (2018)
      The General Data Protection Regulation (GDPR) specifies obligations that shape the way information is collected, shared, provided, or communicated, and provides rights for receiving a copy of their personal data in an ...

    • WinkTalk: A Demonstration of a Multimodal Speech Synthesis Platform Linking Facial Expressions to Expressive Synthetic Voices 

      Cabral, Joao; Székely, Éva; Ahmed, Zeeshan; Carson-Berndsen, Julie (Association for Computational Linguistics, 2012)
      This paper describes a demonstration of the WinkTalk system, which is a speech synthesis platform using expressive synthetic voices. With the help of a webcamera and facial expression analysis, the system allows the ...

    • HMM-based speech synthesis with an acoustic glottal source model 

      Cabral, Joao; Richmond, Korin; Yamagishi, Junichi; Renals, Steve (2009)
      A major cause of degradation of speech quality in HMMbased speech synthesis is the use of a simple delta pulse signal to generate the excitation of voiced speech. This paper describes a new approach to using an ...

    • Introducing Difficulty-Levels in Pronunciation Learning 

      Cabral, Joao; Zahra, Amalia; Carson-Berndsen, Julie; Kane, Mark (International Speech Communication Association (ISCA), 2011)
      This paper presents a method to introduce the notion of a student selected difficulty level for the task of pronunciation learning of a second language. Three difficulty levels, novice, acceptable and native, are ...
