PUMAS: Un Framework que Adapta la Información en Ambientes Ubicuos

Mobile Devices (MD) are characterized by intrinsic reduced capacities (e.g., size of screen, memory, data storage). PUMAS (Peer Ubiquitous Multi-Agent System) is a framework based on agents whose main objective is to provide nomadic users with information adapted to different criteria (their preferences, their location, etc.) when they access Web-based Information Systems (WIS) using such MD. P...

La Extracción de Objetos de Aprendizaje con Metadatos de Diseño Pedagógico

—The generation of digital objects is a costly task and also there are very few tools that support the extraction of learning objects from existing digital materials. In this paper we present the general architecture of a system to extract learning objects from digital material, such as for example HTML pages or Word documents. One of the main features of the proposal is that objects are annota...

Que PASA? The posterior-anterior shift in aging.

A consistent finding from functional neuroimaging studies of cognitive aging is an age-related reduction in occipital activity coupled with increased frontal activity. This posterior-anterior shift in aging (PASA) has been typically attributed to functional compensation. The present functional magnetic resonance imaging sought to 1) confirm that PASA reflects the effects of aging rather than di...

Evaluación de un sistema de traducción automática basado en reglas o por qué BLEU sólo sirve para lo que sirve

Matxin is a rule-based machine translation system which translates to Basque. For its evaluation we have used the HTER metric which calculates the post-editing cost, concluding that 4 of each 10 words would have to be modified to correct the output generated by the system. We have compared the quality of Matxin translations with that of a corpus based system, and the results show that Matxin pe...
