The Logic of Collective Rating

The introduction of participatory rating mechanisms on online sales platforms has had substantial impact on firms' sales and profits. In this note, we develop a dynamic model of consumer influences on ratings and of rating influences on consumers, focussing on standard five-star mechanisms as implemented by many platforms. The key components of our social influence model are the consumer trust in the “wisdom of crowds” during the purchase phase and indirect reciprocity during the rating decision. Our model provides an overarching explanation for well-corroborated empirical regularities. We quantify the performance of the voluntary rating mechanism in terms of realized consumer surplus with the no-mechanism and full-information benchmarks, and identify how it could be improved

Mapping film programming across Post-War Europe (1952): Arts and media

This data paper and the data collection from which it emerges aim to present a fully harmonized data set originating in several research projects on post-war cinema programming. The paper will reflect on the collection and structure of this aggregated data set, that consists of titles of feature films screened for public viewing in cinemas in the cities Bari (Italy), Antwerp and Ghent (Belgium), Gothenburg (Sweden), Leicester (United Kingdom) and Rotterdam (Netherlands) for the year 1952. As comparisons of movie-going patterns between European countries are still rare, this paper offers a model for constructing a data set which can be replicated, scaled up and used to compare, contextualize, and eventually theorize practices of cinema-going across countries at a global level

Quantitative approaches for evaluating the influence of films using the IMDb database

[EN] Why do films certain remain influential throughout film history? The purpose of this paper is to attempt to answer this question. To do so, we adopt some quantitative approaches that facilitate an objective interpretation of the data. The data source we have chosen for this study is the Internet Online Movie Database (IMDb), and in particular, one of its sections called "Connections", which lists references made to a film in subsequent movies and references made in the film itself to previous ones. The extraction and analysis of these networks of citations allows us to draw some conclusions about the most influential movies in film history, identifying their distinguishing features, and considering how their popularity has evolved over time.This work is part of the Project "Active Audiences and Journalism.

Identification of key films and personalities in the history of cinema from a Western perspective

Abstract The success of a film is usually measured through its box-office revenue or through the opinion of professional critics; such measures, however, may be influenced by external factors, such as advertisement or trends, and are not able to capture the impact of a film over time. Thanks to the recent availability of data on references among movies, some researchers have started to use citations patterns as an alternative method for ranking movies. In this paper, we propose a novel ranking method for films based on the network of references among movies, calculated by combining four well known centrality indexes: in-degree, closeness, harmonic and PageRank. Our objective is to measure the success of a movie by accounting how much it has influenced other movies produced after its release, from both the artistic and the economic point of view. We apply our method on a subset of the IMDb (Internet Movie Database) citation network consisting of around 47,000 international movies, and we derive a list of films that can be considered milestones in the history of cinema. For each movie we also collect data on its year of release, genres and countries of production, to analyze trends and patterns in the film industry according to such features. We also collect data on 20,000 directors and almost 400,000 performers (actors and actresses), and we use the network of references and our score of movies for evaluating their career, and for ranking them. Since the IMDb dataset we employ is highly biased toward European and North American movies and personalities, our findings can be considered relevant principally for Western culture

Global cinema distribution: a large-scale data-driven study of film screenings

This interdisciplinary study combined the fields of digital humanities, new cinema history, and cultural economics. It used innovative visualisation and computational techniques to engage with big data from the global film industry. The study established a method for investigating and analysing the temporal and spatial nature of contemporary cinema distribution
