Multilingual extension of a temporal expression normalizer using annotated corpora

This paper presents the automatic extension to other languages of TERSEO, a knowledge-based system for the recognition and normalization of temporal expressions originally developed for Spanish. TERSEO was first extended to English through the automatic translation of the temporal expressions. Then, an improved porting process was applied to Italian, where the automatic translation of the temporal expressions from English and from Spanish was combined with the extraction of new expressions from an Italian annotated corpus. Experimental results demonstrate how, while still adhering to the rule-based paradigm, the development of automatic rule translation procedures allowed us to minimize the effort required for porting to new languages. Relying on such procedures, and without any manual effort or previous knowledge of the target language, TERSEO recognizes and normalizes temporal expressions in Italian with good results (72% precision and 83% recall for recognition).

Plantas atípicas de Cymbalaria aequitriloba (Viv.) A.Chev. cultivadas en la comarca del Matarraña (Teruel)

Cymbalaria aequitriloba (Viv.) A.Chev., es una planta endémica del área Tirrénica (Sicilia, Córcega, Cerdeña y algunos puntos de Italia peninsular), que también alcanza las Islas Baleares. Ha sido encontrada en Torre de Arcas (Teruel) como una planta cultivada o accidental, presente en jardineras de floración invernal, constituyendo un elemento muy particular de la jardinería popular del Matarraña aragonés. Que sepamos, es la primera vez que se cita esta especie en España peninsular. Presenta una gran variabilidad morfológica lo que dificulta su identificación, no obstante es fácilmente diferenciable de C. muralis, la especie más cultivada en la zona. En esta región, tienen por costumbre remover la tierra tras la floración pues la planta pierde belleza, luego vuelve a aparecer en la siguiente estación por renuevo vegetativo o algunas plantas de semilla, motivo que no nos ha permitido estudiar plantas en fructificación. Todo Aragón, pero especialmente el Matarraña, tuvieron estrechos lazos comerciales con Italia durante el s. XIV-XV (principalmente exportando la lana), hecho que pudo favorecer el intercambio de materiales vegetales, como ya se ha podido constatar previamente con otras plantas similares.

Il valore del voto: Italia e Spagna nel dibattito sulla rappresentanza politica liberale (1860-1870)

During the 1860's and 1870's, Spain and Italy experienced a convergence of debates on the significance of political representation in the framework of Liberal State. Spain suffered a political and social crisis, ending with the Revolution of 1868 and the adoption of male universal suffrage in 1878. Its coeval Italy began to build its new Kingdom, anxious about state building, as well as the relevance of electoral processes in the Constitutional scheme. Although members of parliament and essayists of both countries well knew their neighbour's political reality, a dialogue on representation didn't occur. Nonetheless, we believe it is useful to analyse the survey drawn by the Italian publicist in the light of current knowledge of the opinions that prevailed in Spain. What sense did they give to the general election? How did they understand the value of the vote? Who were considered eligible voters? These questions comprise the main subjects of the essay.

The Early Miocene “Bisciaro volcaniclastic event” (northern Apennines, Italy): a key study for the geodynamic evolution of the central-western Mediterranean

The Early Miocene Bisciaro Fm., a marly limestone succession cropping out widely in the Umbria–Romagna–Marche Apennines, is characterized by a high amount of volcaniclastic content, characterizing this unit as a peculiar event of the Adria Plate margin. Because of this volcaniclastic event, also recognizable in different sectors of the central-western Mediterranean chains, this formation is proposed as a “marker” for the geodynamic evolution of the area. In the Bisciaro Fm., the volcaniclastic supply starts with the “Raffaello” bed (Earliest Aquitanian) that marks the base of the formation and ends in the lower portion of the Schlier Fm. (Late Burdigalian–Langhian p.p.). Forty-one studied successions allowed the recognition of three main petrofacies: (1) Pyroclastic Deposits (volcanic materials more than 90 %) including the sub-petrofacies 1A, Vitroclastic/crystallo-vitroclastic tuffs; 1B, Bentonitic deposits; and 1C, Ocraceous and blackish layers; (2) Resedimented Syn-Eruptive Volcanogenic Deposits (volcanic material 30–90 %) including the sub-petrofacies 2A, High-density volcanogenic turbidites; 2B, Low-density volcanogenic turbidites; 2C, Crystal-rich volcanogenic deposits; and 2D, Glauconitic-rich volcaniclastites; (3) Mixing of Volcaniclastic Sediments with Marine Deposits (volcanic material 5–30 %, mixed with marine sediments: marls, calcareous marls, and marly limestones). Coeval volcaniclastic deposits recognizable in different tectonic units of the Apennines, Maghrebian, and Betic Chains show petrofacies and chemical–geochemical features related to a similar calc-alkaline magmatism. The characterization of this event led to the hypothesis of a co-genetic relationship between volcanic activity centres (primary volcanic systems) and depositional basins (depositional processes) in the Early Miocene palaeogeographic and palaeotectonic evolution of the central-western Mediterranean region. The results support the proposal of a geodynamic model of this area that considers previously proposed interpretations.
