Lexicalization and Generative Power in CCG
Get PDFThe weak equivalence of Combinatory Categorial Grammar (CCG) and Tree-Adjoining Grammar (TAG) is a central result of the literature on mildly context-sensitive grammar formalisms. However, the categorial formalism for which this equivalence has been established differs significantly from the versions of CCG that are in use today. In particular, it allows restriction of combinatory rules on a per grammar basis, whereas modern CCG assumes a universal set of rules, isolating all cross-linguistic variation in the lexicon. In this article we investigate the formal significance of this difference. Our main result is that lexicalized versions of the classical CCG formalism are strictly less powerful than TAG
San Girolamo dei Croati a Roma: gli Schiavoni e il cantiere sistino
No full textLa chiesa di San Girolamo presso l’Augusteo, oggi nota come San Girolamo dei Croati, fu costruita per volontà di Sisto V Peretti (1585-1590), già in precedenza cardinale titolare della chiesa, come tempio della comunità degli immigrati che parlavano un idioma slavo meridionale ed erano di fede cattolica. La fabbrica fu realizzata in soli due anni (1587-1589) e la decorazione pittorica fu finita già nel 1590. Il papa marchigiano inoltre eresse la chiesa a titolo collegiale e istituì un capitolo nazionale. La vastità e l’efficacia degli interventi sistini nelle architetture e nell’organizzazione degli Illirici in città rispecchia in scala minore l’operato del papa a Roma e nella Curia, sempre con delle conseguenze a lungo termine. Il presente contributo propone di indagare i rapporti del cardinale Peretti, successivamente papa Sisto V, con la comunità illirica a Roma, domandandosi sulla partecipazione del collettivo nazionale nell’episodio del grande rinnovo artistico della sede. Inoltre, la maggior visibilità e rappresentanza data agli Illirici nella Città Eterna, trattandosi di una “nazione” i cui territori d’origine furono divisi tra l’Impero asburgico, l’Impero ottomano, la Repubblica di Venezia e la piccola Repubblica di Ragusa (Dubrovnik), viene osservata attraverso il prisma della politica papale negli anni dopo la conclusione del Concilio di Trento
La solitudine dell’ambasciatore. Condizioni e rischi dell’ufficio nella prima età moderna (secoli xv-xvii)
No full textQuesto saggio analizza le considerazioni relative alla posizione dell’ambasciatore inserito nel modello cortigiano e affronta in particolar modo gli snodi relativi al cortocircuito che si poteva creare a causa della necessità di coniugare i rapporti che l’ambasciatore residente teneva con il proprio principe e con i membri della corte di destinazione. Emerge la significativa presenza all’interno della trattatistica e di alcuni scritti di cancelleria di suggerimenti e consigli volti a individuare dei percorsi di salvaguardia della posizione del legato
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
