Social Network Analysis of the Knowledge Network in Public Health in the National Observatory of Colombia: An Analysis of Documents ; Análisis de redes sociales de la red de conocimiento en salud pública del Observatorio Nacional de Salud de Colombia: un análisis de documentos ; Análise de redes sociais da rede de conhecimento em saúde pública do Observatório Nacional de Saúde da Colômbia: uma análise de documentos

Introduction: Social Network Analysis (SNA) is useful to identify the proximity between agents and the level of knowledge betwixt them. The objective of the research was to carry out an SNA of the public health knowledge network of the National Health Observatory. Materials and methods: 78 technical documents were collected from the network actors during the 2015-2019 period, which were analyzed employing text mining technics using R language program from directed networks and analyzing different indicators such as: density, diameter, distance, degree centrality and indegree centrality. Results: the interaction analysis pointed out that the agents, which conform the public health knowledge network, show a greater interest in the evaluation of public policies (82 nodes) and non-transmittable diseases (79 nodes). In this category, it was shown low densities indicating that there is a low connectivity between agents. Indegree centrality of the World Health Organization (WHO) and the Pan American Health Organization (PAHO) were higher than the national agents. Conclusions: from the text mining of documentary productions, SNA allowed to identify interactions between the actors in all the analyzed categories. It showed a greater interaction in terms of evaluation and implementation of policies and dimensions of the Ten-Year Public Health Plan associated with a high mortality. ; Introducción: Los análisis de redes sociales (ARS) son útiles para identificar la proximidad entre actores y el grado de conocimiento entre ellos. El objetivo de este estudio fue realizar un ARS de la red de conocimiento en salud pública (RCSP) del Observatorio Nacional de Salud. Materiales y métodos: Se recolectaron 78 documentos técnicos de los actores de la red durante el periodo 2015-2019, los cuales fueron analizados empleando técnicas de minería de texto mediante el lenguaje de programación R, a partir de redes dirigidas y analizando indicadores de densidad, diámetro, distancia, centralidad de grado y centralidad de grado de entrada ...
