The proposed framework, that was named IPEAD (acronym for Ideation, Prioritization, Execution, Analysis and Documentation), was based on Sean Ellis' High Tempo Testing framework and in the concepts explored by Eric Ries on its Lean Startup book. A real case study is presented to illustrate each step of the proposed framework as well as the tools used on the process. The proposed framework could be used by companies or institutions that wish to improve their results through the use of A/B tests.","PeriodicalId":284178,"journal":{"name":"Proceedings of the XIV Brazilian Symposium on Information Systems","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133731355","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}

Some approaches, like Social BPM, argue that own clients can contribute with the business process innovations, but these clients have also own interests and motivations, making that collaboration a challenge. It is argued that before contributing with a process, people should understand it. One way to give the processes particularities is using digital games. In that sense, the research proposal is to study the interactions of processes through digital games, and such is necessary to think how design digital games, aiming to make easier the process representation in games. Therefore, this paper presents a mapping method between processes models elements and digital game design elements, focusing in facilitate the processes representations in games. From this method, have been made case studies in order to check the mapping similarities performed with the same process, and the mapping replicability to different processes. As result, we have observed that the mapping method seems useful to get digital game design elements based on business processes models, helping the representation of them as digital games.","PeriodicalId":284178,"journal":{"name":"Proceedings of the XIV Brazilian Symposium on Information Systems","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129502798","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}

Poorly elaborated questions can lead to answers with meaningless brased or naive interpretations. Therefore, it may be interesting to reuse, partially or totally, questionnaires already created with the same purpose. In this paper we compare QSMatching with the vector model to calculate the similarity between questionnaires and consequently to obtain a ranking of questionnaires according to the user's query. In order to verify the effectiveness, an experiment was carried out comparing QSMatching and the vector model. The result of the analysis of the experiment shows that QSMatching is more effective than the vector model for questionnaires retrieval.","PeriodicalId":284178,"journal":{"name":"Proceedings of the XIV Brazilian Symposium on Information Systems","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129898761","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}

Emerging technologies for security such as biometric identification based on EEG signals, although promising, still require extensive research and further refinement before applied in practice. This work address the problem of EEG channel selection for biometric identification. Five forms of EEG signal segmentation are explored before the feature extraction by autoregressive model (AR model). Channel selection is performed with two approaches, genetic algorithms and search-based ranking, and we use the classifiers k-nearest neighbor (KNN) and support vector machines (SVM) for identification. The results indicate that it is possible to decrease up to 9 channels, regardless of individuals, and hold an accuracy close to the one obtained with all the 64 channels.","PeriodicalId":284178,"journal":{"name":"Proceedings of the XIV Brazilian Symposium on Information Systems","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116857493","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}

Moreover, an analysis of some datasets widely used in this research field in the light of the proposed characteristics will be made. The results have shown that datasets used broadly by researchers nowadays are outdated and unreproducible.

This problem appears in several real situations, playing a fundamental role in reducing costs and improving the efficiency and reliability of the service. In practice, there are often restrictions on the \"time window\", which corresponds to a certain period of the day on which deliveries can be made. Despite the great relevance of this type of constraint, there are no results in the literature that combine stochastic demand and time window constraints. In this work, we propose a system, using advanced techniques of operational research, to solve the inventory routing problem with stochastic demand, considering time window constraints, as well as additional constraints of maximum inventory capacities in both the client and the depot and individual confidence level of the customer service.","PeriodicalId":284178,"journal":{"name":"Proceedings of the XIV Brazilian Symposium on Information Systems","volume":"257 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133435749","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 solutions adopted to eliminate the vulnerabilities inserted by such components is to update the component to a more recent version that corrects the vulnerability. However, updating a component may require code refactoring, updating other components and inserting new vulnerabilities in the application. There are several tools that perform the analysis and management of dependencies of the projects, but few tools present information about vulnerabilities of the new versions, incompatibilities and updates of the dependencies of the components. This article, therefore, presents dep|ct (depict), a tool that aims to identify the known vulnerable components used by the applications and help in the decision on the updating of such components, in order to mitigate the vulnerabilities added to the projects through the vulnerable dependencies. Results of the empirical evaluation carried out on two projects show that the tool can be used to assist in deciding on the update of known vulnerable components.","PeriodicalId":284178,"journal":{"name":"Proceedings of the XIV Brazilian Symposium on Information Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123291913","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 study analyzed the inclusion of of usability and accessibility practices in activities of the process applied in its development. Thus, observed practices were grouped according to ISO/IEC 12207 standards.
