Wiki Leopardi
No full textWiki Leopardi è una piattaforma digitale di studio che si basa sul software open source MediaWiki e che ospita l’edizione digitale della tradizione a stampa dei "Canti" di Giacomo Leopardi. Wiki Leopardi costituisce un utile strumento per la filologia leopardiana. Sebbene infatti la piattaforma si basi sull’edizione critica cartacea curata da Gavazzeni nel 2009 ("Canti" e "Poesie disperse", edizione critica diretta da F. Gavazzeni, Accademia della Crusca, Firenze, 2009) tuttavia ne rappresenta un’implementazione: grazie all’ambiente digitale vengono rappresentate più chiaramente le fasi testuali e le diverse forme delle edizioni licenziate da Leopardi. La libertà dalle costrizioni della pagina cartacea permette una più facile organizzazione del vasto materiale testuale e si possono quindi ricostruire edizioni che non hanno mai ricevuto una pubblicazione critica autonoma (come quella dei "Versi" del 1826). Grazie alla rappresentazione fotografica dei testimoni, inoltre, è possibile studiare gli aspetti grafici e paratestuali a cui Leopardi poneva massima attenzione (egli si diceva «sofistichissimo» nella stampa). Inoltre, risulta evidente come l’apparato critico e l’evoluzione delle varianti siano più semplici da comprendere rispetto alle precedenti edizioni critiche cartacee
Multikernel Activation Functions: Formulation and a Case Study
No full textThe design of activation functions is a growing research area in the field of neural networks. In particular, instead of using fixed point-wise functions (e.g., the rectified linear unit), several authors have proposed ways of learning these functions directly from the data in a non-parametric fashion. In this paper we focus on the kernel activation function (KAF), a recently proposed framework wherein each function is modeled as a one-dimensional kernel model, whose weights are adapted through standard backpropagation-based optimization. One drawback of KAFs is the need to select a single kernel function and its eventual hyper-parameters. To partially overcome this problem, we motivate an extension of the KAF model, in which multiple kernels are linearly combined at every neuron, inspired by the literature on multiple kernel learning. We provide an application of the resulting multi-KAF on a realistic use case, specifically handwritten Latin OCR, on a large dataset collected in the context of the ‘In Codice Ratio’ project. Results show that multi-KAFs can improve the accuracy of the convolutional networks previously developed for the task, with faster convergence, even with a smaller number of overall parameters
From print to digital: A web edition of Giacomo Leopardi’s Idilli
No full textAlthough most would agree that the future of the scholarly edition lies in the digital
medium, it is the print scholarly edition that is still more often cited and read. The
production of digital scholarly editions (DSEs) is still seen as an experimental field whose
methodology has not yet settled to the extent that a digital editing project can be
approached with the same confidence as the making of a print edition. This article
describes an experimental conversion of a print scholarly edition—Giacomo
Leopardi’s Idilli by Paola Italia (2008)—into a DSE. This posed a challenge due to the
the complexity of its internal evidence, but was also relatively short and suitable for an
experimental edition. Our objective was to assimilate into a web-based DSE all the information contained in the text and apparatus of the print edition. We also sought to
discover whether the making of a DSE today that could fully utilize the affordances of the
web, would necessarily place a significant technical load on editors who are more accustomed to solving textual problems. We review briefly a number of generic tools for
making DSEs and describe two attempts at making our own DSE of Leopardi’s Idilli: a
wiki edition whose primary purpose was pedagogical and a DSE based on the software
used to make the Charles Harpur Critical Archive (Eggert, 2019, Charles Harpur Critical
Archive. http://charles-harpur.org). We compare these experiences and draw conclusions about the prospects of making DSEs today
In codice ratio: OCR of handwritten Latin documents using deep convolutional networks
No full textAutomatic transcription of historical handwritten documents is a challenging research problem, requiring in general expensive transcriptions from expert paleographers. In Codice Ratio is designed to be an end-to-end architecture requiring instead limited labeling effort, whose aim is the automatic transcription of a portion of the Vatican Secret Archives (one of the largest historical libraries in the world). In this paper, we describe in particular the design of our OCR component for Latin characters. To this end, we first annotated a large corpus of Latin characters with a custom crowdsourcing platform. Leveraging over recent progresses in deep learning, we designed and trained a deep convolutional network achieving an overall accuracy of 96% over the entire dataset, which is one of the highest results reported in the literature so far. Our training data are publicly available
Soggettività normativa. Saggi su identità, alterità e comunicazione
No full textThe ethical and political debate of our time still appears marked by the so called "clash of civilizations". The thesis, expressed by S.P. Huntington in his 1996 discussed volume, and the acute polemics that are followed from it have contributed to reopen the controversial problem around a correct relationship between the individual liberty and the normative dimension of human conduct projecting it on the sceneries opened by the globalization phenomena. In this frame, the necessity to consider inseparable in moral reflection both the terms identity-otherness finds a renewed confirmation. With it, also the opportunity to assemble on the dynamics of personality the fire of the philosophical attention reveals itself to be conclusive. From here the attempt by the Author 'to test' some possible theoretical proposals expressed by authoritative philosophical voices of XXth century through the radically contingent and historical approach of Kierkegaard to the problem of personality

Il mare come limite di paura in Salvatore Niffoi
No full textSpeak of the limits of an island and one immediately thinks of the sea, first and only border. Several writers have wanted to analyze the relationship of Sardinia with its borders, that form not only a geographical boundary, but also cultural and historical. It also represents a necessary step towards a new future (as in Il quinto passo è l'addio of Sergio Atzeni), a necessary elsewhere (as in Oltremare of Mariangela Sedda), a source of livelihood (in Il mare intorno of Giulio Angioni) or a kind of temple to fear and respect (as in the contribution of Michela Murgia in the collection Carta de logu). This and more is the sea for the Sardinian writers, until the denial of this (as in the text by Marcello Fois In Sardegna non c'è il mare).
Salvatore Niffoi gives an overview of the border closely related to the nature of his characters, which are all (or almost) from the inland areas of Sardinia, Barbagia, a sort of island within the island, where the crossing of familiar territories already represents a break with their own personal tradition.
Considering the ten novels published by the author to date, we will analyze the view of the sea horizon as frightening, but also as a divide, not only physical but also social: those who cross the sea, come back (if they return) completely changed, and, most of the time, without the principles considered positive by the residents of the communities
<p>From <i>Bruges-la-Morte</i> to <i>Le Mirage</i>. The loss of a character?</p>
No full textThe title of Bruges-la-Morte by Georges Rodenbach's novel written in 1892, could be considered without much effort an eponymous title, considering the city of Bruges as the main character of the story. That is a statement by the same author in fact, the city is not only the place where the story develops, but the character that affects and causes actions themselves of the protagonist of the novel, the widower Hugues Viane. If the intent of the author is certainly realized in the novel, what about the city's role in the posthumous play adapted from Bruges-la-Morte, entitled Le Mirage? Shall we perhaps resign to the loss of a character, transformed irreversibly to a pure scenario? Or maybe is it possible through dialogue and staging made to recreate the atmosphere of anguish and sense of death that emanates from the Rodenbach’s canals, bells and belfries ? The objective of this proposed study is therefore to investigate the differences between the novel and the play works to highlight the different textual aspects which focuses differently in the two Rodenbach’s works
Filipe Carreira da Silva, Mead and Modernity. Science, Selfhood and Democratic Politics
No full textGeorge H. Mead: A Therapy for the Malaise of Modernity? In his recent volume on Mead, Filipe Carreira da Silva proposes an interpretation of the pragmatist’s thought that develops through three fundamental points of reference. According to the author, science, selfhood and democratic politics constitute “the pillars” of a new approach to the problem of modernity; an approach in which the mutual interchange between these moments projects on the theoretical level a reflection of the relational ..
