Optimal Parsing for Dictionary-Based Compression
2013
Dictionary-based compression algorithms include a parsing strategy to transform the input text into a sequence of dictionary phrases. Given a text, such process usually is not unique and, for compression purposes, it makes sense to find one of the possible parsing that minimise the final compression ratio. This is the parsing problem. In more than 30 years of history of dictionary-based text compression only few optimal parsing algorithms were presented. Most of the practical dictionary-based compression solutions need or prefer to factorise the input data into a sequence of dictionary-phrases and symbols. Those two output categories are usually encoded via two different encoders producing …
Question Answering with BERT: designing a 3D virtual avatar for Cultural Heritage exploration
2022
Recent technological developments are changing how people experience physical and virtual environments. Technologies like Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR), today, are impacting daily life and are being used in various domains including Cultural Heritage. Applying intelligence to applications using these technologies, through AI and Deep Learning can provide a more immersive user experience. In this paper, we propose the design of a system that realize an avatar with question-answering capabilities, for the specific purpose of giving help in immersive navigation of cultural heritage sites. It is based on a BERT model tailored to the Italian language and wi…
[Re]Constructing Lost Realities, Possible Worlds and Future Perspectives Through Digital and Public Humanities
2022
The 2022 volume of Magazén is devoted to practical aspects in the Digital and Public Humanities. The first issue is thus entitled [re]constructions, focusing on the wide array of practices that prospered in our wide field for [re]configuring lost realities, [re]creating long gone dimensions, [re]building likely scenarios, [re]considering exhibition settings, and [re]covering disappeared traces of historical and cultural value.

Can you feel it will you tell me. Encouraging sentiment expression on the web
2015
In a recent trend in web communication, news outlets and blog platforms allow readers to express opinions about what they have read by choosing an associated feeling, or sentiment ex- pression. This emerging trend, fitting between liking and full text comments, has not still found the popularity it should. The thesis of this paper is that this is also due to the way the sen- timent choice is presented to the user. In order to test this hy- pothesis we have devised a pilot experiment; results confirm that a simpler way of choice increases sentiment expression and yields result that are more aligned with ground truth.
Quanta in Sound, the Sound of Quanta: A Voice-Informed Quantum Theoretical Perspective on Sound
2022
Humans have a privileged, embodied way to explore the world of sounds, through vocal imitation. The Quantum Vocal Theory of Sounds (QVTS) starts from the assumption that any sound can be expressed and described as the evolution of a superposition of vocal states, i.e., phonation, turbulence, and supraglottal myoelastic vibrations. The postulates of quantum mechanics, with the notions of observable, measurement, and time evolution of state, provide a model that can be used for sound processing, in both directions of analysis and synthesis. QVTS can give a quantum-theoretic explanation to some auditory streaming phenomena, eventually leading to practical solutions of relevant sound-processing…
FiST: a Physics-based Operator for Planar Symmetry Preferences

Un approccio multidisciplinare per lo studio del tesoro degli argenti di Morgantina
2015
Lo studio si inserisce nell’ambito della tutela e della valorizzazione del patrimonio artistico culturale, mettendo a servizio di metodiche tradizionali già consolidate lo sviluppo di nuove Tecniche per l’Informazione e la Comunicazione (TIC) dei Beni Culturali. In questa sede si descrivono alcune delle fasi di indagini di un progetto scientifico di ricerca pluridisciplinare che ha come finalità la tutela, la conservazione e il monitoraggio nel tempo di un prezioso nucleo di reperti in argento del cosiddetto “Tesoro di Eupolemo”. La collezione appartenente al Museo archeologico di Aidone, rappresenta un’inestimabile testimonianza del ricco patrimonio della nostra cultura isolana, di età ell…

Human Visual Perception and Retinal Diseases
2010
Retinal diseases are causing alterations of the visual perception leading sometimes to blindness. For this reason, early detection and diagnosis of retinal pathologies is very important. Using digital image processing techniques, retinal images may be analyzed quickly and computer-assisted diagnosis systems may be developed in order to help the ophthalmologists to make a diagnosis. In this paper we described shortly two computer-assisted systems for the detection of retinal landmarks (optic disc and vasculature) together with a brief introduction to the human visual system and to some alterations of the visual perception caused by retinal diseases.
