As a result, they have a great deal of difficulty absorbing oral content, either in written or spoken form, even in the oral language (LO) of their native country. In addition, if it is already difficult to a deaf to access information in the oral language of your country, obstacles to accessing information in foreign languages become almost insurmountable, reducing the level of access to information. Among the approaches to the problem, one of the most promising ones involves the use of automatic translators to translate written or spoken content into sign language through an avatar. However, the vast majority of these machine translation platforms are focused on translating a single oral language into a single associated sign language. In order to expand the range of oral languages that Brazilian deaf people could have access to, this article investigates the use of \"text-to-text\" machine translation mechanisms before the \"text-to-gloss\" machine translation. The idea is to evaluate the offer of a service for automatic translation of digital content (text, audio or video, for example) in any oral language for the Brazilian Language of Signals (LIBRAS). As a way of validating the proposal a prototype based on the Suite VLibras was constructed. A series of computational and user evaluations were carried out to verify if the proposed flow of chained translations allows the suitable understanding of the content in foreign languages.","PeriodicalId":338362,"journal":{"name":"Proceedings of the 23rd Brazillian Symposium on Multimedia and the Web","volume":"38 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":"114485555","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}

The total absence of information about new users is one of the main challenges in this area, and it is known in the literature as Ramp-up Problem. In this scenario, non-personalized strategy are chosen for simplicity, domain independence and effectiveness. State-of-the-art strategies assume that popular items are more likely to represent useful recommendations when the user profile is not known. In contrast, other strategies consider that diversifying recommendations represents potential chances of attracting new users. This work performs an extensive characterization of this problem, in order to contrast the main existing techniques. Our analyses point to a trade-off of popularity and diversity, suggesting that these two dimensions are essential to the Ramp-up problem. However, the main e-commerce systems insist on presenting only strategies that consider accuracy, prioritizing popularity over diversity. The results show that, indeed, both dimensions are relevant to this important scenario in e-commerce.","PeriodicalId":338362,"journal":{"name":"Proceedings of the 23rd Brazillian Symposium on Multimedia and the Web","volume":"44 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":"130593208","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}

Mostly of these solutions have been supported by the cloud communication technologies due to the need of using accurate classification models. In an attempt to solve problems related to the smartphone orientation (e.g. landscape) in the user's body, new types of features classified as orientation independent have arisen in the last years. In this context, this paper presents an extensive comparative study between all the features mapped in literature derived from inertial sensors. A number of experiments were carried out using two databases containing data from 30 users. Results showed that the new orientation independent features proposed in literature cannot discriminate properly between the users' activities using the inertial sensors. In addition, this paper provides an extensive analysis of these type of features and a tool that implements all methodological process of human activity recognition based on smartphones.","PeriodicalId":338362,"journal":{"name":"Proceedings of the 23rd Brazillian Symposium on Multimedia and the Web","volume":"4 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":"126534899","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}
