In 2002, Brazilian national network for identification and location of missing children and adolescents established four important goals to tackle this serious problem. Our work is motivated by two of them: to create an unified register of missing people data and reported cases, and to promote information sharing among network members. Aiming at these goals, we developed Myosotis, an information system that performs analysis inside an unified database about Brazilian missing people. Data is collected autonomously from different sources. Our first empirical results show that our system outperforms all existent solutions in the country, including the official database from Brazilian government, by up to 122% when considering the number of distinct registers. Also, our pattern analysis module is capable of giving insights about what people's characteristics make them more statistically susceptible to disappear. All this consolidated information and the aggregated database as well are publicly available through a friendly open-source web application and a public API. We show how we developed this system, first in the country and still rare in the world, and the main challenges that this system still needs to overcome.","PeriodicalId":284178,"journal":{"name":"Proceedings of the XIV Brazilian Symposium on Information Systems","volume":"51 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":"121271674","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 types of information and a large amount of data stored in these systems leads to challenges related to the efficiency of error tracking, such as the presence of duplicate bug reports that hinder productivity. Ideally, a tester should identify a duplicate error report before creating it. In this work, we propose the AVS (Automatic Versatile Search tool), that contributes to the identification of duplicate errors based on Information Retrieval and Text Mining techniques. As proof of concept, we implemented the AVS in the context of the Motorola Test Center (MTC) at the Informatics Center of UFPE. Every search by a new error report candidate is preprocessed. Then, the calculation of similarity between the new report and those available in the database generates a ranked list of similarity. In the end, the results are clustering to produce a more advanced process of identifying duplicate potentials. Experiments carried out on a corpus of about 750,000 reports have revealed the tool's usefulness in identifying duplicate error reports.1","PeriodicalId":284178,"journal":{"name":"Proceedings of the XIV Brazilian Symposium on Information Systems","volume":"32 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":"127701497","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}

Spectrum-Based Fault Localization (SFL) is a consolidated debugging technique due to it is relative low execution cost. SFL pinpoints the most suspicious program elements by ranking lines, methods, classes and packages that are more likely to contain faults. Recently, SFL tools have been proposed to help developers during debugging. These tools use different metaphors to represent the suspiciousness of program elements. In this paper, we compare two SFL tools that utilize different metaphors: Jaguar and CodeForest. Jaguar uses a textual representation, presenting the most suspicious elements of a program as a list sorted by suspiciousness. CodeForest uses three-dimensional visualization metaphor, presenting a program as a cacti forest in which basic blocks are represented as thorns, methods as branches, and classes as cacti. We present the results of an evaluation with 76 students using both tools. The perception of usability of the tools was assessed using a questionnaire based on the Technology Acceptance Model (TAM). Three factors were considered to measure the impact of use of the tools in the debugging activity: intention of use, usefulness, and ease of use. The results suggest that there is not statistical difference in the perception of usability between CodeForest and Jaguar.","PeriodicalId":284178,"journal":{"name":"Proceedings of the XIV Brazilian Symposium on Information Systems","volume":"2 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":"130850710","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}

However, the monitoring approaches commonly provided to such managers usually address only indicators at the level of the services implementing the business processes, which are technical measures directed to Information Technology (IT) managers. This paper introduces the StrAli-BAM (Strategic Alignment with Business Activity Monitoring) approach to assist strategic alignment between business and IT through monitoring non-functional business process requirements based on Quality of Service (QoS) levels. StrAli-BAM aims to enable business areas' managers to monitor the execution of business processes by focusing on the indicators that are really sensitive to the execution of business processes. StrAli-BAM consists of: a non functional requirement monitor and an infrastructure for SOA event-based execution and monitoring. This paper was performed following the research method of project science. The proposed approach is evaluated via a proof of concept in an online shopping scenario with non-functional response time requirement monitoring.","PeriodicalId":284178,"journal":{"name":"Proceedings of the XIV Brazilian Symposium on Information Systems","volume":"17 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":"134476408","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 RAH allows the monitoring of user actions, offering services in the area of medical care, in the accompaniment of the elderly, health monitoring, fitness tracking, home and work automation, among others. The RAH can be seen as an Information System composed by three steps: data collection and preprocessing, feature extraction and classification. Despite the abundance of works proposed for this subject, an important issue to be addressed is how to choose the tools and methods to be used in each step of the RAH. This choice is a difficult process, because it involves comparing the results obtained by other works, most of which use private datasets, extract different sets of features, and use different classification algorithms. This paper aims to characterize and compare the main tools, methods and databases for the RAH task. In addition, it aims to provide guidance and guidelines for future research in the area. Experiments were performed in order to identify the main attributes to be used in the classification. It can observed the attributes mean, standard deviation, and variance produce the best models to the classification task.","PeriodicalId":284178,"journal":{"name":"Proceedings of the XIV Brazilian Symposium on Information Systems","volume":"42 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":"127143687","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}
