By using polls, chats, news and other mechanisms in order to dialogue more directly with these viewers. However, social networks provide only a partial way of interaction for this type of media, since they were not designed to deal with the peculiarities of TV programs. To such purpose Second Screen applications were created, and they can be understood as an extension of the TV screen in which any information or interactions can be presented to users through apps for smartphones or tablets. Unlike social networks, Second Screen apps are made available by broadcasters specifically for TV users. For TV Stations, it is necessary to develop several applications in order to cover the various programs in their schedule, and as a consequence this generates expenses to companies, which may explain the massive use of social networks by these broadcasters in order to interact with viewers nowadays. Therefore, this paper aims at presenting a supporting architecture to a dynamic update of a generic Second Screen app. Such architecture enables the deployment of broadcasters, programs, media, quizzes and any other Second Screen features without the need to create new apps by broadcasters or install new apps by users. The results demonstrated several benefits that the versatility of the proposed architecture offers to all those involved in the chain of television content production.","PeriodicalId":338362,"journal":{"name":"Proceedings of the 23rd Brazillian Symposium on Multimedia and the Web","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128766057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An usual approach for specifying such synchronization is to mark the moments when a given effect has to be executed in the main media object. Multimedia authoring languages provide a way to mark moments of a media object through anchors. An anchor indicates a temporal portion (video frames or audio samples) in relation to its parent media object. However, to synchronize such portions with sensory content can be costly. When, for example, a scene component appear multiple times on the media content. This problem was tackled in previous work by providing an approach for creating abstract anchors in declarative multimedia documents. An abstract anchor represents (possibly) several media anchors. By using a scene recognition software, the anchors where duplicated whenever the same component was identified on the main media. Such approach, was proven useful for creating automatic sensory effects based on video recognition. This paper extends the proposal of abstract anchors in order to enable the automatic generation of sensory effects using sound recognition. This paper also extends the Abstract Anchor Processor to implement media pre-processing and to adapt the sound recognition software response.","PeriodicalId":338362,"journal":{"name":"Proceedings of the 23rd Brazillian Symposium on Multimedia and the Web","volume":"724 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134542282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the major obstacles is due to the fact that this information is available almost entirely in the oral language only, while the deaf communicate naturally using signals. There are some solutions available in the literature for automatic translation of oral language content into sign languages, but they are usually restricted to translating content into a single input oral language. The objective of this work is to investigate the feasibility of generalization of a translation strategy with syntactic-semantic treatment, originally directioned from Brazilian Portuguese for LIBRAS, to define a flexible architecture for the construction of automatic translators of several oral languages for associated sign languages. The hypothesis we wish to evaluate is that an extensible and configurable translation core, based on the interpretation of formally defined rules and grammars acting at the morphological, syntactic or semantic levels, can be used to implement new machine translation initiatives for sign languages or as a way to improve the quality of translation in existing tools.","PeriodicalId":338362,"journal":{"name":"Proceedings of the 23rd Brazillian Symposium on Multimedia and the Web","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130479203","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

More recently, there has been an increasing availability of \"smart\" services that, among other tasks, help users to locate, understand and analyze automatically media of interest. Smart services are often based on algorithms from data mining and related areas such as machine learning and artificial intelligence. Beyond the efficiency and effectiveness of theses services, there is a growing concern about the fairness, accountability and transparency associated with them, which is the subject of this talk. Fairness comprises guarantees that algorithms are neither biased nor discriminatory, even when they are mathematically and computationally correct. Accountability means the identification of entities, human or not, that should be held responsible for the algorithms' consequences. Transparency is the property of generating understandable explanations on the algorithms' outcomes. In this talk we are going to discuss and characterize data mining algorithms, in particular when applied to web and social networks, with respect to fairness, accountability and transparency, and present strategies that assure these properties while satisfying other usual requirements such as precision, effectiveness, and privacy preservation.","PeriodicalId":338362,"journal":{"name":"Proceedings of the 23rd Brazillian Symposium on Multimedia and the Web","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115732014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
