Graph-based exploration and clustering analysis of semantic spaces

2019

Abstract The goal of this study is to demonstrate how network science and graph theory tools and concepts can be effectively used for exploring and comparing semantic spaces of word embeddings and lexical databases. Specifically, we construct semantic networks based on word2vec representation of words, which is “learnt” from large text corpora (Google news, Amazon reviews), and “human built” word networks derived from the well-known lexical databases: WordNet and Moby Thesaurus. We compare “global” (e.g., degrees, distances, clustering coefficients) and “local” (e.g., most central nodes and community-type dense clusters) characteristics of considered networks. Our observations suggest that …

Ultreya, suseya, Santiago!” Viaggio e spazialità ne La ballata dei pellegrini

2020

Per studiare dal punto di vista della geografia culturale alcuni aspetti del pellegrinaggio a Santiago de Compostela, in Spagna, il capitolo prende in considerazione un testo letterario, il romanzo autobiografico "La ballata dei pellegrini" della scrittrice francese Edith De La Héronnière, pubblicato per la prima volta nel 1993 e tradotto in italiano nel 2004. Il romanzo racconta l’esperienza del pellegrinaggio giacobeo effettuato dall’autrice negli anni Novanta assieme a tre compagni di viaggio partendo da un cammino francese. In particolare, attraverso l’analisi di alcune parti del testo, si indagano le modalità attraverso le quali la narrazione costruisce e descrive lo spazio fisico e si…

The contribution critically and from a geographical perspective discusses the connection between propaganda comics and cartoons in the period of twentieth-century totalitarianisms. The way in which space real and symbolic is implicated through the rhetoric and dialectics of power in social economic and identity dynamics is then explored. In order to study some aspects of the pilgrimage to Santiago de Compostela from the point of view of cultural geography in Spain the chapter takes into consideration a literary text the autobiographical novel "The pilgrims' ballad" by the French writer Edith De La Héronnière first published in 1993 and translated into Italian in 2004. The novel recounts the experience of the Jacobean pilgrimage carried out by the author in the nineties together with three traveling companions starting from a French journey. In particular through the analysis of some parts of the text the ways in which the narration constructs and describes the physical and symbolic space of the pilgrimage are investigated. In this way it is possible to explore the way in which peculiar attributions of meaning inscribe the experience of pilgrimage in a symbolic universe that is both personal and collective at the same time.

Ultrametric Algorithms and Automata

2015

We introduce a notion of ultrametric automata and Turing machines using p-adic numbers to describe random branching of the process of computation. These automata have properties similar to the properties of probabilistic automata but complexity of probabilistic automata and complexity of ultrametric automata can differ very much.

Smooth surjections and surjective restrictions

2017

Given a surjective mapping $f : E \to F$ between Banach spaces, we investigate the existence of a subspace $G$ of $E$, with the same density character as $F$, such that the restriction of $f$ to $G$ remains surjective. We obtain a positive answer whenever $f$ is continuous and uniformly open. In the smooth case, we deduce a positive answer when $f$ is a $C^1$-smooth surjection whose set of critical values is countable. Finally we show that, when $f$ takes values in the Euclidean space $\mathbb R^n$, in order to obtain this result it is not sufficient to assume that the set of critical values of $f$ has zero-measure.

National conference on Emerging trends in Architecture and allied fields

Abstract Evidences of trade & merchant communities in Indus Valley civilizations are available from that is 3500 BC. Being important trading destination in world map Indian Bazaars played major role in generating economic means for common man. Spices, grain, cotton, sugar, Indigo these were some of important trading goods exported all over world. Traditional Bazaar, Bazaarpeths/ wards, Market squares are most happening places in historic towns of India. Their accessibility, openness, Flexibility, Meandering surprises, colors, and crowd pertains its own character. These are most flexible & organic setups evolved over the period of time responding to political, economical & cultural setup of …

AGRIGENTO SMART - Integration and sustainability in the regeneration of an urban public space. A case study.

2017

Agrigento, city of the Valley of the Temples, for a few decades it is only known for the "unauthorised development" (or sacco edilizio between the '50s and' 70s of the twentieth century). Today is trying to regain possession of those urban spaces subtracted from a foolish speculation, assigning to them a renewed urban and social connotation, beauty and utility, trying to heal some of the major wounds of the past. With the awareness that it is not a path easy, nor immediate. The issue of public space, and its renewed use today, assumes a crucial role in the process of urban regeneration. Our focus, of multidisciplinary approach, is aimed at the southern edge of the old town called "Square Ra…

Generalized Metric Spaces and Locally Uniformly Rotund Renormings

2009

A class of generalized metric spaces is a class of spaces defined by a property shared by all metric αspaces which is close to metrizability in some sense [Gru84]. The s-spaces are defined by replacing the base by network in the Bing-Nagata-Smirnov metrization theorem; i.e. a topological space is a αspace if it has a αdiscrete network. Here we shall deal with a further re- finement replacing discrete by isolated or slicely isolated. Indeed we will see that the identity map from a subset A of a normed space is A of a normedslicely continuous if, and only if, the weak topology relative to A has a s-slicely isolated network. If A is also a radial set then we have that the identity map Id : (X,…

Urban Resilience: A New Way to Live the Urban Space

2022

Since the dawn of the urban age, the issues and values of the urban settlement have varied considerably through the centuries, as well as the theory of ideal and perfect urban form, but the importance of urban spatial structure has never been erased. Nowadays, the city is still in the middle of our civilisation, but the relationships between nested socio-ecological systems are more complex because the human-environment interactions are not bidirectional. Last month news told us that the new coronavirus has not been the first case of a virus that skips the species, reaching up to man, but unlike other recent viruses it had been–and it still is–the first that after centuries has caused signif…

Lo spazio poetico al limitare del margine urbano

2018

The marginal space of the contemporary city no longer has a recognizable form. It has lost relationship with the natural horizon, renouncing however its own poetic vocation. Architecture has the task of reestablishing this relationship. Through the analysis of some projects by Francesco Venezia it is possible to show that contemporary architecture still has the proper instruments to recover the poetic space on the urban border.
