    Análisis comparativo entre: «el análisis exploratorio de datos» y los modelos de «árboles de decisión» y «kmeans » en el diagnóstico de la malignidad en algunos exámenes de cáncer de mama. Un estudio de caso

    The exponential growth of medical data has generated the need to implement new techniques of information analysis that support decision making. The objective of this article is to identify the aggregated value that data mining models have in decision making in the information given by exploratory analysis. It was used a case study methodology for two data sets, that look to determine the malignity of detected masses, in the breasts of patients, through the interpretation of attributes registered from the mases. The results show a complementary behavior of both techniques. © 2018.

    Interactivity Model 2.0: Social communication dynamics in organizational contexts
    (ELSEVIER SCIENCE INC, 2016-11-01) Giraldo Marín, L.M.; Tabares Betancur, M.S.; Joyanes Aguilar, L.; Giraldo Marín, L.M.; Tabares Betancur, M.S.; Joyanes Aguilar, L.; Universidad EAFIT. Departamento de Ingeniería de Sistemas; I+D+I en Tecnologías de la Información y las Comunicaciones
    This article presents the Interactivity Model 2.0, which aims to support the communicative process of knowledge transfer 2.0 developed in organizations that follow a social business model. This model has its origin in SECI and Ba interaction models and in the Open Communication Interactivity Model. This study defines Interactivity building on two concepts: role and interaction. The study considers role as actors taking part in Knowledge Transfer Process 2.0, and interaction as the process of communication that enables a transfer. The research tests this model through a case study at a Colombian Information Technology Company. The results show the changes of the communicative process in social settings and allow the identification of a message, a role, the direction and control of a message, and the knowledge contributions of the various actors of the Knowledge Transfer Process 2.0.

    Modelo para optimizar el proceso de gestión de negocio combinando minería de procesos con inteligencia de negocios desde almacenes de datos
    (Revista Espacios, 2017-01-01) Giraldo Mejía, J.C.; Jiménez Builes, J.; Tabares Betancur, M.S.; Giraldo Mejía, J.C.; Jiménez Builes, J.; Tabares Betancur, M.S.; Universidad EAFIT. Departamento de Ingeniería de Sistemas; I+D+I en Tecnologías de la Información y las Comunicaciones
    Business processes are vital elements for organization management and to evaluate the organization by using KPI. Nevertheless, results measuring hardly finds events that can be detected from stored information in data warehouses, which is analyzed in different periods of time and can also be used to improve the process. In this paper a model that optimizes business processes is shown. This was achieved by studying other research works and carrying out iterations on a specific process, where BPM is integrated into mining processes and dimensional modelling. © 2017.
