Evaluating knowledge-based approaches to the multilingual extension of a temporal expression normalizer

The extension to new languages is a well known bottleneck for rule-based systems. Considerable human effort, which typically consists in re-writing from scratch huge amounts of rules, is in fact required to transfer the knowledge available to the system from one language to a new one. Provided sufficient annotated data, machine learning algorithms allow to minimize the costs of such knowledge transfer but, up to date, proved to be ineffective for some specific tasks. Among these, the recognition and normalization of temporal expressions still remains out of their reach. Focusing on this task, and still adhering to the rule-based framework, this paper presents a bunch of experiments on the automatic porting to Italian of a system originally developed for Spanish. Different automatic rule translation strategies are evaluated and discussed, providing a comprehensive overview of the challenge.

Teaching-learning process of historical heritage: a Journey as a beginning, path and end

The implantation of new university degrees within the European Higher Education Area implies the need of innovative methodologies in teaching and learning to improve the skills and competencies of students and to answer the growing needs that society continuously demands to heritage management experts. The present work shows an application of the teaching methodology proposed during the international workshop entitled “I International Planning Preservation Workshop. Learning from Al Andalus”, which included the participation of the University of Alicante and Granada, Università Politecnico di Milano and Hunter College City University of New York; where we tried to dissolve traditional boundaries derived of interuniversity cooperation programs. The main objective of the workshop was to discuss and debate the role of urban Historical Centers within the Global Heritage by the integrated work through multidisciplinary teams and the creation of a permanent international working group between these universities to both teach and research. The methodology of this workshop was very participatory and considered the idea of a new learning process generated by "a journey experience." A trip from global to local (from the big city to the small village) but also a trip from the local (historical) part of a big city to the global dimension of contemporary historical villages identified by the students through a system of exhibition panels in affinity groups, specific projects proposed by lecturers and teachers or the generation of publications in various areas (texts, photographs, videos, etc.). So, the participation of the students in this multidisciplinary meeting has enhanced their capacity for self-criticism in several disciplines and has promoted their ability to perform learning and research strategies in an autonomous way. As a result, it has been established a permanent international work structure for the development of projects of the Historical City. This relationship has generated the publication of several books whose contents have reflected the conclusions developed in the workshop and several teaching proposals shared between those institutions. All these aspects have generated a new way of understanding the teaching process through a journey, in order to study the representative role of university in the historical heritage and to make students (from planning, heritage management, architecture, geography, sociology, history or engineering areas) be compromised on searching strategies for sustainable development in the Contemporary City.

Propuesta para un viraje en el estudio de los medios en Las Márgenes

Este artículo explora diferentes tipos de apropiación de tecnologías mediáticas en las márgenes y propone un cambio en el acercamiento investigativo en diferentes niveles: 1) en lugar de centrarse en tecnologías individuales, la investigación sobre medios en las márgenes debe examinar cómo los/as comunicadores locales se desenvuelven en ecologías mediáticas que ofrecen recursos y retos específicos en cada situación histórica; 2) en lugar de tratar de determinar si las tecnologías mediáticas usadas en las márgenes son nuevas u obsoletas, digitales o no, es urgente comprender cómo los/as comunicadores asentados en lo local detectan necesidades de información y comunicación específicas y usan las tecnologías disponibles para abordar tales necesidades; 3) la investigación sobre medios en las márgenes debe esclarecer cómo las/los protagonistas de este tipo de comunicación ciudadana y comunitaria reinventan, hibridan, reciclan y tienden lazos entre plataformas tecnológicas. En resumen, para entender las tecnologías mediáticas en las márgenes la investigación debe asumir altos niveles de complejidad, debe mantener la noción de ecologías mediáticas y entender cómo, a nivel local, comunicadores comunitarios profundamente inmersos en lo cotidiano e histórico, ajustan las tecnologías mediáticas a las necesidades de sus comunidades.
