MR-Radix: a multi-relational data mining algorithm
Carlos Roberto Valêncio,Fernando Takeshi Oyama,Paulo Scarpelini Neto,Angelo Cesar Colombini,Adriano Mauro Cansian,Rogeria Cristiane Gratao de Souza,Pedro Luiz Pizzigatti Corrêa +6 more
TL;DR: The comparative study between PatriciaMine and MR-Radix confirmed efficacy of the multi-relational approach in data mining process both in terms of execution time and in relation to memory usage.
Proceedings ArticleDOI
Real Time Delta Extraction Based on Triggers to Support Data Warehousing
Carlos Roberto Valêncio,Matheus Henrique Marioto,Geraldo Francisco Donegá Zafalon,José Márcio Machado,Julio Cesar Momente +4 more
TL;DR: A structure capable of performing this task by means of triggers and a tool developed for the automatic generation of the SQL (Structured Query Language) code to create these trigger, besides showing its performance and comparing it to other techniques are proposed.
Proceedings ArticleDOI
Knowledge extraction using visualization of hemoglobin parameters to identify thalassemia
Carlos Roberto Valêncio,M.N. Tronco,A.C. Bonini-Domingos,C.R. Bonini-Domingos,Caetano Traina,Agma J. M. Traina +5 more
TL;DR: This work presents the results of applying a visual data mining tool, called FastMapDB, to detect the behavioral pattern exhibited by a dataset of clinical information about hemoglobinopathies known as thalassemia.
Journal ArticleDOI
A system proposal for automated data cleaning environment
Carlos Roberto Valêncio,Toni Jardini,Victor Hugo Penhalves Martins,Angelo Cesar Colombini,Marcio Zamboti Fortes +4 more
TL;DR: In this paper, the authors developed an automated configurable data cleaning environment based on training and physical-semantic data similarity, aiming to provide a more efficient and extensible tool for performing information correction which covers problems not yet explored such as semantic and autonomy of the cleaning implementation process.
Proceedings ArticleDOI
Project Scope Management: A Strategy Oriented to the Requirements Engineering.
Igor Luiz Lampa,Allan de Godoi Contessoto,Anderson Rici Amorim,Geraldo Francisco Donegá Zafalon,Carlos Roberto Valêncio,Rogeria Cristiane Gratao de Souza +5 more
TL;DR: The objective of this work is to propose the integration of the scope management with the requirements engineering, in order to better identify the requirements of a project and to understand what needs to be done, contributing to the success of projects.
