New Approaches to OCR for Early Printed Books
2020
Books printed before 1800 present major problems for OCR. One of the main obstacles is the lack of diversity of historical fonts in training data. The OCR-D project, consisting of book historians and computer scientists, aims to address this deficiency by focussing on three major issues. Our first target was to create a tool that identifies font groups automatically in images of historical documents. We concentrated on Gothic font groups that were commonly used in German texts printed in the 15th and 16th century: the well-known Fraktur and the lesser known Bastarda, Rotunda, Textura und Schwabacher. The tool was trained with 35,000 images and reaches an accuracy level of 98%. It can not on…
History teaching: real problems and interessed polemics
2006
En diversos países se ha tratado de poner límites a las innovaciones educativas, de diverso calado, que se estaban produciendo en la enseñanza de la historia, con la intención de retornar a un modelo de enseñanza más próximo a sus características tradicionales, a pesar de las muy razonadas críticas que este modelo tradicional había recibido. Las razones aducidas para tal reversión han variado de un país a otro, pero el objetivo compartido ha sido el de establecer unos programas más dirigistas y cerrados, de tipo marcadamente enciclopédico, en los que las posibilidades de actuación innovadora del profesorado, por una parte, y las de un aprendizaje más razonado del alumnado, por la otra, qued…
Edizioni, traduzioni e censure: Cicognara, i fratelli Giachetti e l’editoria artistica di inizio Ottocento
2018
This article focuses on Leopoldo Cicognara's role as an advisor of the Italian publisher Giachetti (Prato). After a brief analysis of three key publications (Cicognara's history of sculpture; Séroux d'Agincourt's history of medieval and early-modern Art; Winckelmann's history of ancient art), the authors discuss the role of censorship and its consequences for nineteenth-century art books. The documentary appendix includes a complete transcription of all reports by the Florentine censor p. Mauro Bernardini.
Tall Tales for a Mass Audience: Dutch Penny Prints and Spanish Aleluyas in Comparative Perspective
2021
Abstract In this article we compare Dutch penny prints with Spanish Aleluyas, focusing on three specific functions of this premodern mass medium: popularising and adapting theatre plays; standardising (folk/fairy) tales; adapting and popularising literary classics. Via these functions we address the discrepancies between the two countries considering the materiality of the penny prints, the growth of the production, but also the transition from a predominantly religious, towards a more profane content. Striking was the lack of educative and edifying initiatives in Spain in contrast to the Dutch ideological strategies. We observed some interesting similarities as well. Although in both count…
El manuscrito del 'Cancionero de Baena' (PN1) : Descripción codicológica y evolución histórica
2018
The present article attempts to establish as accurately as possible the chronological trajectory of the unique codex of the Cancionero de Baena (PN1 in the Dutton nomenclature). It begins with a detailed examination of the codicological aspects of the manuscript, which serve to date its origin to around 1465. This origin, combined with the historical data, supports a conjecture that the manuscript probably belonged to Gonzalo de Beteta, an official of both Enrique IV and the Catholic Kings. It would have passed from him to his grandson, Jorge de Beteta y Cardenas, who gave it to the Real Biblioteca de El Escorial in 1576. The article then follows the vicissitudes of the manuscript from its …
Las publicaciones divulgativas como vehículo de difusión del patrimonio arqueológico: bibliografía de guías arqueológicas en España 1975-2005
2008
Se realiza una aproximación a las publicaciones de carácter divulgativo como medio para difundir y dar a conocer el patrimonio arqueológico. Para ello, se identifica y caracteriza un determinado género de publicaciones divulgativas: las guías arqueológicas. Se presenta una bibliografía de la literatura de este género publicada a lo largo de las tres últimas décadas en España, analizando la evolución diacrónica del número de publicaciones, la cobertura geográfica, las entidades editoras, la estructura y los contenidos recogidos en este tipo de obras. We analyse Popular Science Archaeological Books as a way of spreading the popularization of archaeological heritage. In that sense, we identifi…
INTERPRETARE ORAZIO CON ORAZIO? A PROPOSITO DI CARMINA, LIBRO IV
2011
In the work “Mutat terra vices. Identità, cambiamento e memoria culturale nell’ultimo Orazio” (Palermo 2010), I focused my attention on interpretative and methodological questions concerning the last Horatian book of carmina. In this paper the aim is to demonstrate how the topic of change and discontinuity points out, on the surface of these poems, the presence of conspicuous interferences between the execution of a role by authorial "persona", and the expression, at the same time, of role distance. I mean here especially to describe how gift, reciprocity and exchange in patronage frames contributed to the definition of Horace’s self and of his official duties as interpreter of common memor…
Multi-agent-based Order Book Model of financial markets
2006
We introduce a simple model for simulating financial markets, based on an order book, in which several agents trade one asset at a virtual exchange continuously. For a stationary market the structure of the model, the order flow rates of the different kinds of order types and the used price time priority matching algorithm produce only a diffusive price behavior. We show that a market trend, i.e. an asymmetric order flow of any type, leads to a non-trivial Hurst exponent for the price development, but not to "fat-tailed" return distributions. When one additionally couples the order entry depth to the prevailing trend, also the stylized empirical fact of "fat tails" can be reproduced by our …
Statistical analysis of financial returns for a multiagent order book model of asset trading
2007
We recently introduced a realistic order book model [T. Preis, Europhys. Lett. 75, 510 (2006)] which is able to generate the stylized facts of financial markets. We analyze this model in detail, explain the consequences of the use of different groups of traders, and focus on the foundation of a nontrivial Hurst exponent based on the introduction of a market trend. Our order book model supports the theoretical argument that a nontrivial Hurst exponent implies not necessarily long-term correlations. A coupling of the order placement depth to the market trend can produce fat tails, which can be described by a truncated Lévy distribution.
