Notably, distributed teams suffer adverse physical and temporal dispersion effects during an information exchange. To mitigate problems arising from interactions, it is important to understand the communication structure of teams during distributed projects. The objective of this work is to present the Communication Framework for Distributed Software Development. This framework groups a set of distributed projects communication concepts and enables a unified view of all stakeholders’ intercommunications that use many interaction technologies. The goal of this framework is to portray the dynamics of the interaction between distributed teams in a multi-tier structure, and each tier approaches a single function in the intercommunication process. We analyzed all interactions from distributed teams after developing an experimental IT Project, using the content analysis method to validate the Communication Framework for Distributed Software Development. The main contribution of this work is the framework specification, and the investigation, which has the potential to help mapping communication patterns in DSD. Moreover, this framework comprises interfaces for communication assessment and includes intercommunications from automated engineering tools as bots.","PeriodicalId":39760,"journal":{"name":"Journal of the Brazilian Computer Society","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138514939","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}

OpenStreetMap (OSM) is useful resource which offers a wide variety of easily accessible datasets under an Open Database License (ODbL), including those that can be hard to find for some areas, such as parks, building footprints, and street centerlines. There are several ways to access and download OSM data, but many of these methods can be difficult to use due to their limited functionality or complexity. Additionally, they may require users to process the data, or purge unnecessary portions. In this piece, I explore multiple methods for downloading OSM data and evaluate them alongside the QuickOSM plugin for QGIS.","PeriodicalId":39760,"journal":{"name":"Journal of the Brazilian Computer Society","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45285226","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}

Novais, Manoel Mendonça","doi":"10.1186/s13173-020-00099-y","DOIUrl":"https://doi.org/10.1186/s13173-020-00099-y","url":null,"abstract":"Context Design problems have been recognized as one of the main causes behind the loss of software systems’ quality. Agglomerated design problems impact the quality even more. So, organizing and analyzing the relationship between design problems and concerns as agglomerations is a possible way to enhance the identification of defective source code artifacts. Problem As different systems evolve in varied manners, it is important to analyze if the evolution of agglomerated design problems can reveal cases of discrepancies and inconstancies through time. We call these cases non-uniformity of agglomerations, and they can prevent the use of agglomerations in approaches to mitigate design problems (e.g., prediction models). To the best of our knowledge, we consider that this problem has not been investigated yet. Goal This study aims to comprehend the degree to which the non-uniformity of agglomerations is either the most common or the most exceptional situation during the evolution of software projects. We perform this investigation by grouping software projects under two transverse dimensions: types and domains of software. Method To this end, we performed a two-phase investigation: in phase I, we analyzed the historical data obtained from fifteen software projects split as three groups of types of software (distributed, service-oriented, and mobile projects); in phase II, we analyzed the evolution of six projects grouped as two domains of software (graph and timeseries databases). For each phase, we (i) mined instances of a design problem (code complexity) and concerns from the source code of projects, (ii) agglomerated the instances of code complexity around the concerns and analyzed them according to the grouped projects, and (iii) examined the resulting dataset with the help of visualizations and a statistical analysis. Results/Discussion Types of software actually shows a tendency to reveal cases of non-uniformity. On the other hand, domains of software show a partial advantage regarding the production of more uniform agglomerations through evolution.","PeriodicalId":39760,"journal":{"name":"Journal of the Brazilian Computer Society","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138514943","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}

Delgado","doi":"10.1186/s13173-020-00098-z","DOIUrl":"https://doi.org/10.1186/s13173-020-00098-z","url":null,"abstract":"Computerized adaptive testing (CAT) based on item response theory allows more accurate assessments with fewer questions than the classic paper and pencil (P&P) test. Nonetheless, the CAT construction involves some key questions that, when done properly, can further improve the accuracy and efficiency in estimating the examinees’ abilities. One of the main questions is in regard to choosing the item selection rule (ISR). The classic CAT makes exclusive use of one ISR. However, these rules have differences depending on the examinees’ ability level and on the CAT stage. Thus, the objective of this work is to reduce the dichotomous test size which is inserted in a classic CAT with no significant loss of accuracy in the estimation of the examinee’s ability level. For this purpose, we analyze the ISR performance and then build a personalized item selection process in CAT considering the use of more than one rule. The case study in Mathematics and its Technologies test of the ENEM 2012 shows that the Kullback-Leibler information with a posterior distribution ( KLP ) has better performance in the examinees’ ability estimation when compared with Fisher information ( F ), Kullback-Leibler information ( KL ), maximum likelihood weighted information ( MLWI ), and maximum posterior weighted information ( MPWI ) rules. Previous results in the literature show that CAT using KLP was able to reduce this test size by 46.6 % from the full size of 45 items with no significant loss of accuracy in estimating the examinees’ ability level. In this work, we observe that the F and the MLWI rules performed better on early CAT stages to estimate examinees’ proficiency level with extreme negative and positive values, respectively. With this information, we were able to reduce the same test by 53.3 % using the personalized item selection process, called ALICAT, which includes the best rules working together.","PeriodicalId":39760,"journal":{"name":"Journal of the Brazilian Computer Society","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138514962","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}
