Among the different technologies with important implications today in such areas as education, health and business, videostreaming is highlighted. This considering how this technology facilitates the access to multimedia content remotely, live or offline. The goal of this paper is to propose a test environment for the support of the video streaming service, using open source tools. Moreover, this work proposes, as part of the environment, a stress measurement tool (Hermes), which allows obtaining the response times to establish multiple RTSP connections to streaming servers. The methodology used in this work is divided into four phases: analysis of technologies and tools, configuration of the video streaming environment, design and implementation of Hermes, and finally tests. This methodology allowed the construction of the test environment and its evaluation, through the stress measurement tool Hermes. Finally, in this work we demonstrate how the proposed environment becomes a reference point for different application environments that require the implementation of a video streaming service.
Objective— To develop a search model for judicial decisions supported by natural language processing that allows analyzing the text of jurisprudential sentences. Additionally, link-data is used to take advantage of the interrelation of content in related court decisions and improve search processes. Methodology— The search model was built in two phases: the first is the training phase to generate the models required to create an index, and second, a search phase where the user enters a search string that is used to find the documents (court decisions) more related to the search. The model was compared with other existing search engines of the Supreme Court of Justice of Colombia. The evaluation was divided into 2 steps. 1) Evaluation of the results obtained in each search, 2) User satisfaction with the results obtained in the searches solution. Results— The developed platform outperforms the existing search system of the court regarding user satisfaction and precision. Conclusions— The designed model for judicial sentences based on Natural Language Processing (NLP) and linked contributes to improving the user experience and the precision of the jurisprudence search.
<p>En la actualidad existen diversas herramientas para la codificación de contenidos de vídeo, las cuales son usadas para cambiar el formato y modificar el nivel de compresión de los contenidos. En lo que respecta a las herramientas libres de codificación, por lo general estas carecen de interfaz gráfica, obligando al usuario a realizar este proceso mediante línea de comandos. En este artículo se presenta una propuesta de un proceso de codificación de contenidos multimedia educativos, considerando herramientas libres. A nivel metodológico, este trabajo se desarrolló en 4 fases: análisis de tecnologías y herramientas, diseño e implementación de la herramienta de codificación, construcción del escenario de videostreaming y evaluación del escenario de videostreaming. Como principales resultados de este trabajo se destacan la construcción de una herramienta de codificación para contenidos multimedia educativos y la conformación de un escenario de transmisión de streaming a partir de la herramienta desarrollada. Este trabajo permite concluir que la herramienta desarrollada posibilita la automatización del proceso de codificación de contenidos multimedia, haciendo uso de herramientas libres. Así mismo, el escenario conformado puede ser considerado como referencia en diversos entornos de aplicaciones que requieran el montaje e implementación de servicios basados en vídeostreaming, como es el caso de los procesos de educación virtuales.</p>
