A técnica proposta foi aplicada em projetos reais com o objetivo de avaliar a precisão e a variação do IDCAcum e consequentemente da Estimativa no Término (ENT). Então, foi comparado com a técnica tradicional de Gerenciamento de Valor Agregado (GVA).

We present computational experiments made with instances generated from PPI networks with approximately 8.000 proteins and 29.000 interactions among them. As experimentally verified, the two proposed models were able to solve all instances in a very satisfactory amount of computational time.","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":"114966430","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}

As the principal pollinating agent, bees are essential for the food production for humans and the ecosystems sustainability. However, a combination of habitat destruction, climate change and exposure to pesticides and pathogens has led to a significant decrease in bee population. Here we propose a method to recognize status patterns of Apis mellifera colonies through the application of data mining techniques. Using a real dataset from the HiveTool.net containing Apis mellifera temperature, humidity and weight data, we identified 3 status patterns in the observed hive. Our results suggest that the recognized patterns are consistent with a honey bee colony life cycle. Based on the found patterns, we propose a high accuracy classification model capable of automatically identifying colony status for new samples.","PeriodicalId":284178,"journal":{"name":"Proceedings of the XIV Brazilian Symposium on Information Systems","volume":"148 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":"124734488","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}

This paper aims to present a systematic review with the support of the snowballing technique, to raise studies on how to elicit and specify requirements from business process models in BPMN.

Despite its appealing, the increase in the demand for this lending modality depends on a rigorous settlement of the risk assignment to the potential borrowers. Considering this issue, this article discusses an experimental analysis of classification methods for P2P on-line lending default prediction. The performed experiments were based on the application of the implemented classification algorithms over the data mass formed by borrowers' profiles and loan history records of the P2P Lending Club platform. As the main contribution, the study revealed that it is possible to obtain satisfactory prediction results with a set of attributes smaller than those that were used in studies previously presented in the literature. In addition, it could be verified that, since the algorithms based on decision trees have proved highly effective, the use of these methods is a feasible approach to support the development of lending negotiation tools.","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":"134388415","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 research aims to investigate the perception of a user's group facing the possible adoption of the Life360 application in seek for improvement of family safety. The study was conducted by means of questionnaires and interviews with people from the city of Itajubá -- MG. The perceptions collected were analyzed from the perspective of the Diffusion of Innovation Theory and the progressive model of adoption. As a result, a low-cost model that allows evaluating critical points in the process of adoption was obtained.

This paper introduces ColMiner, a tool capable to measure the communication quality in an issue tracking environment through the calculation of the issue comments relevance for the main theme of the discussion (thematic relevance). Its purpose is to identify failures in the communication process. The approach of communication analysis uses some text mining techniques based on the use of graphs to represent the comments textual content. To validate the approach, the relevances calculated by ColMiner are compared with those manually defined by some developers. Finally, the work presents the main funcionalities of ColMiner, highlighting the support to the communications management in software projects, and discuss some threats to validity.","PeriodicalId":284178,"journal":{"name":"Proceedings of the XIV Brazilian Symposium on Information Systems","volume":"271 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":"115665716","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}
