De-identification for privacy protection in multimedia content COST Action IC1206 (2013-2017) De-identification in multimedia content can be defined as the process of concealing the identities of individuals captured in a given set of data (images, video, audio, text), for the purpose of protecting their privacy. This Action aims to facilitate coordinated interdisciplinary efforts (related to scientific, legal, ethical and societal aspects) in the introduction of person de-identification and reversible de-identification in multimedia content.

National Projects

SUSPECT (SecUre SPEeCh Technologies) SUSPECT (2012-2015) The goal of this project is to develop privacy-preserving frameworks for processing voice data. Processing will be performed without having access to the voice, i.e., access to any form of the speech that can be analyzed to obtain information about the talker or what they spoke. Using a combination of tools from cryptography and secure-multiparty computation we will render voice processing algorithms secure, so that the privacy of all parties is preserved. We specifically propose to develop solutions for secure speaker verification and keyword spotting problems.	Voice coaching for reduced stress VOCE (2012-2015) VOCE shall develop methods and algorithms that enable the online classification of stress from live speech with the goal of providing feedback cues to the speaker in real-time to improve his communication skills. The work will focus on detecting and classifying stress in speech by leveraging advanced signal processing and machine learning techniques, complemented with psychological analysis of different aspects of stress perception [3]
MISNIS (Intelligent Mining of Public Social Networks’ Influence in Society) MISNIS (2013-2015) Develop an analysis framework that can help to determine the effect of social networks in society. The intended framework will enable the identification and traction of important events (topics) and key actors within those topics, as well as identify their origin and propagation timeline. Measures and indicators to characterize events will be proposed by the research team and provided by the framework contributing with essential information to understand the social network phenomena and its importance in current world society.	Decision support systems for preventing ICU readmissions IC4U (2013-2015) In this project, we will apply advanced computational and modelling strategies to clinical data sets (including both instrumentation data and text medical notes) in an effort to. 1) identify important factors or features that lead to unfavourable or favourable clinical conditions that determine if a patient should be released or not from that ICU with minimum risk of readmission; 2) Design specific decision models that will support clinician’s decisions in terms of releasing a patient form the ICU, in order to achieve more favourable clinical outcomes.
Intelligent Networked Robot Systems for Symbiotic Interaction with Children with Impaired Development INSIDE (2014-2018) INSIDE explores the scientific and technological challenges involved in developing symbiotic human-robot interactions in the context of a physical game involving children. To this goal, INSIDE investigates how to extend multiagent planning under uncertainty to cooperative scenarios involving human and robot agents. INSIDE also investigates natural forms of interaction (including spoken interactions) and how contextual and environment information (collected by a sensor network) can improve the communication between robot and human agents during joint collaborative tasks involving activities in a physical environment. The outcomes of INSIDE will be deployed in “Centro para o Desenvolvimento da Criança” (CDC, Child Development Center) of Hospital Garcia de Orta, in a physical game specially designed by the INSIDE team. [4]	TRAnslation and Transcription Assisted by Humans on the Internet TRATAHI (2015) The goal of this exploratory project, in cooperation with Carnegie Mellon University, is to design a web-based tool for man-in-the-loop joint robust Automatic Speech Recognition (ASR) and Machine Translation (MT). For this purpose research will be centered on representing the uncertainty of ASR and MT outputs expressed as a lattice, incorporating user feedback to the lattice and sharing information among MT and ASR lattices for improved performance.[5]
Machine Translation for Microblogs MT4M (2015) This exploratory project in cooperation with Carnegie Mellon University aims to develop state of the art technologies for Machine Translation in Microblogs, such as Twitter and Facebook. The developed methods must address the unpredictability and originality of text in this environment. The main tasks involve normalization techniques to convert the input into more standard forms, the usage of continuous space models that are more robust to word variations and the development of MT evaluation techniques suited to this domain.
