We propose a probabilistic object classifier for outdoor scene analysis as a first step in solving the problem of scene context generation. The method begins with a top-down control, which uses the previously learned models (appearance and absolute location) to obtain an initial pixel-level classification. This information provides us the core of objects, which is used to acquire a more accurate object model. Therefore, their growing by specific active regions allows us to obtain an accurate recognition of known regions. Next, a stage of general segmentation provides the segmentation of unknown regions by a bottom-strategy. Finally, the last stage tries to perform a region fusion of known and unknown segmented objects. The result is both a segmentation of the image and a recognition of each segment as a given object class or as an unknown segmented object. Furthermore, experimental results are shown and evaluated to prove the validity of our proposal

Learning contents adaptation has been a subject of interest in the research area of the adaptive hypermedia systems. Defining which variables and which standards can be considered to model adaptive content delivery processes is one of the main challenges in pedagogical design over e-learning environments. In this paper some specifications, architectures and technologies that can be used in contents adaptation processes considering characteristics of the context are described and a proposal to integrate some of these characteristics in the design of units of learning using adaptation conditions in a structure of IMS-Learning Design (IMS-LD) is presented. The key contribution of this work is the generation of instructional designs considering the context, which can be used in Learning Management Systems (LMSs) and diverse mobile devices

The explosive growth of Internet during the last years has been reflected in the ever-increasing amount of the diversity and heterogeneity of user preferences, types and features of devices and access networks. Usually the heterogeneity in the context of the users which request Web contents is not taken into account by the servers that deliver them implying that these contents will not always suit their needs. In the particular case of e-learning platforms this issue is especially critical due to the fact that it puts at stake the knowledge acquired by their users. In the following paper we present a system that aims to provide the dotLRN e-learning platform with the capability to adapt to its users context. By integrating dotLRN with a multi-agent hypermedia system, online courses being undertaken by students as well as their learning environment are adapted in real time

Emotions are crucial for user's decision making in recommendation processes. We first introduce ambient recommender systems, which arise from the analysis of new trends on the exploitation of the emotional context in the next generation of recommender systems. We then explain some results of these new trends in real-world applications through the smart prediction assistant (SPA) platform in an intelligent learning guide with more than three million users. While most approaches to recommending have focused on algorithm performance. SPA makes recommendations to users on the basis of emotional information acquired in an incremental way. This article provides a cross-disciplinary perspective to achieve this goal in such recommender systems through a SPA platform. The methodology applied in SPA is the result of a bunch of technology transfer projects for large real-world rccommender systems

La entrada de las TIC en el ámbito educativo ha producido un cambio de escenario en la práctica docente y este nuevo escenario social necesita unos ciudadanos con conocimientos y habilidades que les permitan enfrentarse a los desafíos de una sociedad en cambio constante. Todos los CEPs han diseñado seminarios con fase a distancia que intentan potenciar el uso de las TIC en los procesos de aprendizaje. Se describen los cambios conceptuales y metodológicos en la práctica de los docentes así como las opiniones de algunos de ellos tras su primer contacto con un seminario semipresencial.

El fenómeno del desplazamiento interno forzado en el mundo representa una problemática de gran envergadura que impacta a aquellas personas que se ven obligadas a migrar dentro del territorio de su país huyendo de las zonas de conflictos y de las persecuciones de los actores armados, debido al contexto de violencia en el que se encuentran y del cual resultan ser las principales víctimas. Así pues, en el caso de Colombia, el desplazamiento forzado interno representa una de las principales consecuencias que ha dejado el contexto de violencia armada sufrido en el país a lo largo de las últimas décadas, lo cual ha llevado a las instancias constitucionales a pronunciarse sobre el accionar del Estado para darle solución a esta problemática. El trabajo se enfoca específicamente en la Sentencia T-025 de 2004 proferida por la Corte Constitucional donde se establece que el país atraviesa por un Estado de Cosas Inconstitucional. De manera particular, a lo largo del análisis se realiza una evaluación de la implementación, cumplimiento y alcance de la Sentencia en la Ciudad de Bogotá, durante la Administración de Samuel Moreno Rojas.
