Automating statistical diagrammatic representations with data characterization

2017

The search for an efficient method to enhance data cognition is especially important when managing data from multidimensional databases. Open data policies have dramatically increased not only the volume of data available to the public, but also the need to automate the translation of data into efficient graphical representations. Graphic automation involves producing an algorithm that necessarily contains inputs derived from the type of data. A set of rules are then applied to combine the input variables and produce a graphical representation. Automated systems, however, fail to provide an efficient graphical representation because they only consider either a one-dimensional characterizat…

Mappe della contemporaneità. Visualizzare la complessità per vivere, comprendere, partecipare.

2020

Si propone una riflessione sulle modalità di visualizzazioni della complessità di contesti territoriali, rese possibili dalle tecnologie dell’informazione connesse agli open data; uno scenario che evidenzia la rilevanza oggi di strumenti e competenze del design della comunicazione e dell’informazione, proponendo una nuova centralità della “mappa”, strumento e modello contemporaneamente di conoscenza, rappresentazione e trasformazione del mondo. Il contributo indaga come le diverse declinazioni di visual mapping, che connettono un contesto reale fisico-geografico ai molteplici livelli di informazione disponibili, possono alimentare nei cittadini consapevolezza e partecipazione a supporto di …

Universal Patterns in Color-Emotion Associations Are Further Shaped by Linguistic and Geographic Proximity

2020

Many of us “see red,” “feel blue,” or “turn green with envy.” Are such color-emotion associations fundamental to our shared cognitive architecture, or are they cultural creations learned through our languages and traditions? To answer these questions, we tested emotional associations of colors in 4,598 participants from 30 nations speaking 22 native languages. Participants associated 20 emotion concepts with 12 color terms. Pattern-similarity analyses revealed universal color-emotion associations (average similarity coefficient r = .88). However, local differences were also apparent. A machine-learning algorithm revealed that nation predicted color-emotion associations above and beyond tho…

A VIRTUAL HUB BROKERING APPROACH FOR INTEGRATION OF HISTORICAL AND MODERN MAPS

2016

Geospatial data are today more and more widespread. Many different institutions, such as Geographical Institutes, Public Administrations, collaborative communities (e.g., OSM) and web companies, make available nowadays a large number of maps. Besides this cartography, projects of digitizing, georeferencing and web publication of historical maps have increasingly spread in the recent years. In spite of these variety and availability of data, information overload makes difficult their discovery and management: without knowing the specific repository where the data are stored, it is difficult to find the information required and problems of interconnection between different data sources and th…

Open sourcing digital heritage : digital surrogates, museums and knowledge management in the age of open networks

2012

I study the emergence of traditional online activities of the museums and their fears in the vivid and multifaceted Internet and how the open Internet is setting out to compete with museums. The second main topic of this work is the role of technology in the openness of digital heritage. Technology is always present when dealing with digital heritage, and understanding the technical framework is essential when evaluating, for example, long-term preservation issues or accessibility. I used three different kinds of sources in my study: literary, case studies and application development. First, I have read studies that are related to digital heritage: museology literature, museum informatics l…

Considerazioni su amministrazione aperta e protezione dei dati personali

2015

Il diritto alla trasparenza totale ed alla conoscibilità delle decisioni amministrative nell'ordinamento italiano invera appieno il principio di pubblicità nelle istituzioni, con riferimento all'esercizio della funzione amministrativa e costituisce diretta applicazione dei principi di legalità, buon andamento, responsabilità e imparzialità della P.A. sanciti dall'art. 97 Cost. e del diritto alla buona amministrazione (art. 41 CDFUE).La trasparenza va quindi intesa come mezzo attraverso il quale le istituzioni pubbliche rendono conto delle proprie decisioni alla collettività garantendo la pubblicità di atti, documenti, informazioni e dati di pertinenza delle pubblica amministrazione ed il pr…

Open Resources as the Educational Basis for a Bachelor-level Project-Based Course

2015

This article presents an innovation-based course concept for project-based learning. In this course, student groups are asked to ideate and implement a software product based on Open Data and Open API releases. By emphasizing students’ own product ideation, the course requires and enhances self-directed learning skills and prompts the students to see the unlimited possibilities in becoming and being a practitioner of the computing discipline. Relatedly, the course provides a tool to improve student self-efficacy, as the students, coached through challenges, come to know that they are able to produce software using various open interfaces.

Biased graph walks for RDF graph embeddings

2017

Knowledge Graphs have been recognized as a valuable source for background information in many data mining, information retrieval, natural language processing, and knowledge extraction tasks. However, obtaining a suitable feature vector representation from RDF graphs is a challenging task. In this paper, we extend the RDF2Vec approach, which leverages language modeling techniques for unsupervised feature extraction from sequences of entities. We generate sequences by exploiting local information from graph substructures, harvested by graph walks, and learn latent numerical representations of entities in RDF graphs. We extend the way we compute feature vector representations by comparing twel…

Visualising maritime vessel open data for better situational awareness in ice conditions

2018

Situational awareness of maritime vessels in ice conditions is important for the operation of supply chains. In the artic sea areas, the ice conditions pose a major challenge for maritime vessels getting stuck in the ice and being significantly delayed in arrival to harbor. Data science and open data provide new opportunities to overcome these challenges. This paper introduces available open data sources and data visualizations that can be used to develop applications, for example, for detecting maritime vessel collision, predicting estimated time of arrival to harbor, as well as maritime vessel route optimization in ice conditions. The paper begins by introducing available open data source…
