    El informe anual Horizon investiga, identifica y clasifica las tecnologías emergentes que los expertos que lo elaboran prevén tendrán un impacto en la enseñanza aprendizaje, la investigación y la producción creativa en el contexto educativo de la enseñanza superior. También estudia las tendencias clave que permiten prever el uso que se hará de las mismas y los retos que ellos suponen para las aulas. Cada edición identifica seis tecnologías o prácticas. Dos cuyo uso se prevé emergerá en un futuro inmediato (un año o menos) dos que emergerán a medio plazo (en dos o tres años) y dos previstas a más largo plazo (5 años)

    The digital parrot: Combining context-awareness and semantics to augment memory

    Get PDF
    People of all ages and backgrounds are prone to forgetting information, even about their personal experiences. Existing systems to support people in remembering such information either continuously record a person’s experiences or provide means to store and retrieve clearly defined, isolated pieces of data. We propose a new approach: combining context-awareness with semantic information. We believe this approach to be superior to the existing systems in certain types of situations. This position paper introduces this approach and our own ongoing project, the Digital Parrot

    Context modeling and constraints binding in web service business processes

    Get PDF
    Context awareness is a principle used in pervasive services applications to enhance their exibility and adaptability to changing conditions and dynamic environments. Ontologies provide a suitable framework for context modeling and reasoning. We develop a context model for executable business processes { captured as an ontology for the web services domain. A web service description is attached to a service context profile, which is bound to the context ontology. Context instances can be generated dynamically at services runtime and are bound to context constraint services. Constraint services facilitate both setting up constraint properties and constraint checkers, which determine the dynamic validity of context instances. Data collectors focus on capturing context instances. Runtime integration of both constraint services and data collectors permit the business process to achieve dynamic business goals
