Analysis and data visualization in bibliometric studies/Analisis y visualizacion de datos en estudios bibliometricos

In recent years, academics with different professional formation other than Information Sciences have been involved in research related to metric studies using approaches and techniques based on bibliometrics; however, these professionals do not have knowledge and necessary competences for conduct metric information studies in a rigorous and methodical way. This article aims to find what are methods and tools used by bibliometrics researchers through a descriptive and textual analysis, using methods such as word co-occurrence in bibliographical data extracted from scientific articles indexing in Web of Science, research area "Library & Information Science." We find most frequently software and tools used in bibliometrics have four levels for data treatment: recovery, preparation, processing and analysis, visualization; and use different methods analysis: networks social, geospatial, thematic, temporal, bibliographic coupling, among others. KEYWORDS Bibliometrics; Computer programs; Data analysis; Data visualization; Co-word analysis. En los anos recientes, academicos de formaciones distintas a las Ciencias de la Informacion con mayor frecuencia realizan estudios utilizando enfoques y tecnicas basados en bibliometria; sin embargo, estos profesionales no siempre tienen los conocimientos y la formacion necesarias para realizar estudios metricos de la informacion de manera rigurosa y metodica. El estudio pretende describir los metodos y herramientas utilizados por investigadores a partir de un analisis de contenido textual empleando metodos de analisis de co-ocurrencia de terminos de articulos cientificos indizados en Web of Science, area de investigacion "Bibliotecologia". Se encontro que los programas y herramientas informaticas mas usadas presentan cuatro niveles de manipulacion de datos: recuperacion, preparacion, procesamiento y analisis, visualizacion; y emplean distintos metodos de analisis: sociogramas, geoespacial, tematico, temporal, acoplamiento, entre otros. PALABRAS CLAVE Bibliometria; Programas informaticos; Analisis de datos; Visualizacion de datos; Analisis de Co-ocurrencia de terminos.
