Allied to this, a management panel allows the therapist to visualize and interact with the sent records, besides personalizing the patient's experience through tips and techniques for anxiety control.

Although collaboration in the development of Free/Libre/Open Source Software (FLOSS) projects is considered one of the decisive factors for its success, there are no studies on its level in the BPS Portal. In addition, there exist few recent studies on the current state of the ecosystem, primarily regarding possible changes of incentive by its promoter, the Federal Government. In this context, an exploratory study was carried out on the GitLab platform of the BPS Portal with two different views: one regarding the representation and historical analysis of its life cycle and its different phases; and another in relation to the level of collaboration within each public software. The results indicated that the BPS Portal would currently be in the final phase of its life cycle (termination). It was also possible to identify a higher level of collaboration in public software created during the amplification phase.","PeriodicalId":348938,"journal":{"name":"Proceedings of the XV Brazilian Symposium on Information Systems","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114914274","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}

On the other hand, satirical news has an entertaining purpose and are mistakenly put on the same boat of objective fake news. In this work, we address the differences between objectivity and legitimacy of news documents, treating each article as having two conceptual classes: objective/satirical and legitimate/fake. Thus, we propose a Decision Support System (DSS) based on a text mining pipeline and a set of novel textual features that uses multi-label methods for classifying news articles on those two domains. For validating the approach, a set of multi-label methods was evaluated with a combination of different base classifiers and then compared to a multi-class approach. Results reported our DSS as proper (0.80 F1-score) in addressing the scenario of misleading news from challenging perspective of multi-label modeling, outperforming the multi-class methods (0.71 F1-score) over a real-life news dataset collected from several portals of news.","PeriodicalId":348938,"journal":{"name":"Proceedings of the XV Brazilian Symposium on Information Systems","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132401427","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}

For this, the project includes bibliographical research on innovation, design and Design Thinking and a research with some students of Information Technology (IT). The results obtained in this study demonstrate that the implementation of a systematic system of Design Thinking in the universities, requires several changes in the academic culture.

Investigating the sociotechnical nature of these types of systems is relevant to the analysis and understanding of the technological development that occur over the years in each scenario. Based on this motivation, the objective of this research is to identify sociotechnical elements of SGE/SIS/SS through a systematic mapping study.

In this context, the existence of tools to identify faults is fundamental in order to assist developers during the evolution of their applications. Different tools and approaches have been proposed over the years, however they have limitations to evolve over time, becoming obsolete quickly. The reason for this is the use of a fixed list of pre-defined faults that are searched in the code. The BugAID tool implements a semiautomatic strategy for discovering bug patterns by grouping the changes made during the project development. The objective of this work is to contribute to the BugAID tool, extending this tool with improvements in the extraction of characteristics to be used by the clustering algorithm. The extended module of the BugAID extraction module (BE) that extracts the characteristics is called BE+. Additionally, an evaluation of the clustering algorithms used for discovering fault patterns in JavaScript software is performed. The results show that the DBScan and Optics algorithms with BE+ presented the best results for the Rand, Jaccard and Adjusted Rand indexes, while HDBScan with BE and BE+ presented the worst result.","PeriodicalId":348938,"journal":{"name":"Proceedings of the XV Brazilian Symposium on Information Systems","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127890627","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}

Thus, this paper aims to present software guidelines for the design of gamified educational technologies to patients with this deficit. The requirements were compiled based on the results of a study conducted with parents, psycho-pedagogues, psychologists and speech therapists. Two main guideline categories were found: (i) behavioral strategies and (ii) gamification elements used, the first being composed of 17 strategies and the second by 12 gamification elements. From these categories and data analysis, 16 system requirements were proposed for the development of gamified applications to people with Attention Deficit Hyperactivity Disorder.","PeriodicalId":348938,"journal":{"name":"Proceedings of the XV Brazilian Symposium on Information Systems","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122566801","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}

Blockchain and smart contracts are enabling new business models and standards to information systems. However, a smart contract needs to be well tested before to be published in a blockchain, since it cannot be changed after being deployed. The execution time to deploy smart contracts and run their tests is considerable because all transactions must be mined before being added to a new block. This work proposes an approach to reuse the execution of the deployment and the setup of unit test in smart contracts to reduce the execution time of these tests. Experiments have shown a large reduction in the execution time of smart contract unit tests, without breaking the principle of test independency.","PeriodicalId":348938,"journal":{"name":"Proceedings of the XV Brazilian Symposium on Information Systems","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123997143","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}
