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…
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…
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…
