No full textÈ intelligenza artificiale o sono solo intelligenti artifici? Automobili guidate da altre macchine, sistemi esperti che diagnosticano patologie con lo stesso grado di affidabilità di un medico specialista, certo. Ma quando le macchine saranno in grado di pensare? Quando l'espressione "intelligenza artificiale" perderà lo statuto di slogan visionario
MultiSemCor: an English/Italian aligned corpus word-annotated with a shared inventory of senses
No full textMultiSemCor is an English/Italian parallel corpus, aligned at the word level and annotated with PoS, lemma and word sense. The parallel corpus has been created by exploiting the SemCor corpus, in which content words are lemmatized and sensetagged with reference to the WordNet lexical database.
The main hypothesis underlying this methodology is that, given a text and its translation into another language, the semantic information is mostly preserved during the translation process. Therefore, if the texts in one language have been semantically annotated and their translations have not, annotations can be transferred from the source language to the target using word alignment as a bridge
Analisi geometrica dei circoli megalitici di Li Muri 8 e La Macciunitta 2. Possibili interpretazioni metriche e numeriche
No full textQualified best fit methods (Monaco et alii 2013) have allowed reliable estimates of the circles diameters and the identification of the length units of two megalithic type-B stone circles of the Arzachena culture. Regular hexagons result inscribable between outer and inner circumferences, although for La Macciunitta 2 with less precision. No particular orientation has been found for the entrances of the two stone circles
«Prendiamoci cura del Pianeta» Un decennio di educazione ambientale
No full textGià 2500 anni fa, il filosofo cinese Confucio affermava: 'Dimmi e lo dimenticherò, mostrami e potrò ricordarlo, coinvolgimi e lo capirò', anticipando così di molti anni l’idea che sta alla base del concetto di democrazia partecipativa: essa lavora a creare le condizioni per cui tutti i membri di una società possano portare contributi significativi ai processi decisionali, concedendo a un numero sempre maggiore di soggetti l’opportunità di accedere direttamente alle decisioni politiche
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
The orientation of the Mithraea in Ostia Antica
Full text linkWe conducted an investigation on the orientations and geometrical content of the Mithraea of Ostia Antica.
A geometrical CAD study based on the most reliable plans from the Archives of the Sovrintendenza Speciale
per il Colosseo, il MNR e l’Area Archeologica di Roma – Ostia Antica, aside with the identification of geometrical
and numerical schemes and associated length units, allowed us to identify the axes of the Mithraea. Then the
orientations of the axes were measured on field by means of a professional compass with ± 0.5° uncertainty.
The distribution of these measured azimuths follows the topography of the city. On the contrary, the Decumanus,
the main street of the town, presents an indubitable orientation toward the Winter Solstice Sunset.
This was ascertained by measuring the coordinates of four significant points along the street with the help of
a palmar Trimble GPS which averages 100 measures per point.
The exceptional density of Mithraea in Ostia led us to suppose that a symbolic cosmic-solar value is to be
searched in the orientation as a whole of the town itself, founded half a millennium before the first presence
of Mithraism in Rome. The Decumanus could be considered the very holder of this symbolic value with its
orientation toward the Winter Solstice Sunset, possibly making of Ostia a very special place for Mithraicism
