Sémiotique de la photographie
No full textPierluigi Basso et Maria Giulia Dondero nous proposent une plongée sans concession dans un univers éminemment problématique : Sémiotique de la photographie peut être lu à la fois comme un livre de référence sur un domaine de pratiques et d’objets culturels propre au XXe siècle, et comme un exemple de problématisation théorique et méthodologique. Les spécialistes de la photographie y trouveront toutes les références nécessaires, et les sémioticiens y verront à l’œuvre une exceptionnelle entreprise de questionnement
Diagrammatic Gestures. Cognition, Mathematics, and Semiotics.
Get PDFhere are words having an extraordinary evocative power. This is precisely the case of “Diagram” and “Gesture”. The frst term covers an interconnected network of concepts like “graph”, “schema”, “form”, “model”, “arrow”, and so on... And the same can be said of the second one: just think, for example, of the ideas of “movement”, “bodily action”, “practical activity” or, more generally, of “doing”. Accounting for them has been, over the last 50 years, the aim of signifcant portions of the work conduction in philosophy (Deleuze, Foucault, Merleau-Ponty), mathematics (Grothendieck, Lawvere, Thom), semiotics (Peirce), and theoretical linguistics (Culioli, Langacker, Pottier). The present issue aims to present the state of the art with regard to the diagrammatic gesture, in particular by taking into account the relations between the disciplines mentioned and the arts and sciences
Semiotic approaches to big data visualization
No full textWith a few exceptions – focusing on journalism (Compagno 2017), on works of art (Chartier, Pulizzotto, Chartrand & Meunier 2019, Dondero 2020), on deep fake videos (Leone 2021, Dondero 2021), and on data epistemology (Bachimont 2018) – semiotics has been late to approach big data. In contrast to information and communication studies, which have been quick to recognize the big data revolution in medical, biological, political, urbanistic, and journalistic practices, and while digital humanities and digital art history continue to offer crucial insight with their analysis of large collections of artworks and heritage objects, semiotics has yet to live up to the big data challenge. In this Punctum issue we have attempted to (1) contribute to the global discussion of possible semiotic approaches to big data theory and methodology; (2) explore specifically an epistemological approach to visualizations of big data, i.e., to their manipulation, design, display, and interpretation; (3) study, from a critical vantage point, the ideologies and epistemic perspectives that underlie the acts of collecting and visualizing big data, prior to their analysis. Our overall objective has been to trace the path that leads from visualization, regarded as a unifying representation of disparate data, to its full elevation to an interpretative device

No full textGoing 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
