Mining customer requirements from online reviews: A product improvement perspective

2016

We propose a filtering model to predict helpfulness of reviews for product design.We provide a way to use the KANO model based on online reviews.We explore how to obtain insights from Big Data through knowledge-based view. Big data commerce has become an e-commerce trend. Learning how to extract valuable and real time insights from big data to drive smarter and more profitable business decisions is a main task of big data commerce. Using online reviews as an example, manufacturers have come to value how to select helpful online reviews and what can be learned from online reviews for new product development. In this research, we first proposed an automatic filtering model to predict the help…

Un diritto per l'Europa industriale. Cultura giuridica ed economia dalla Rivoluzione francese al Secondo Dopoguerra.

2016

Nel 1807 la Francia di Napoleone raccoglieva nel primo Codice di commercio della storia i motivi salienti della cultura giuridica del tempo, e più specificamente quegli aspetti che, emersi nel decennio rivoluzionario, erano usciti indenni dalla “restaurazione” d’inizio secolo: eguaglianza giuridica formale, unicità del soggetto di diritto, prospettiva individualistica, egemonia del diritto di proprietà. Nel corso del XIX secolo la cultura giuridica avrebbe cercato di rielaborare gli schemi ordinanti della codificazione napoleonica, ricalcandone però nel complesso le linee ideologiche e l’impianto concettuale. Diritto ed economia viaggiavano a doppia velocità: sullo sfondo di un’Europa avvia…

Spectral density of the correlation matrix of factor models: a random matrix theory approach.

2005

We studied the eigenvalue spectral density of the correlation matrix of factor models of multivariate time series. By making use of the random matrix theory, we analytically quantified the effect of statistical uncertainty on the spectral density due to the finiteness of the sample. We considered a broad range of models, ranging from one-factor models to hierarchical multifactor models.

La corruption et le droit du commerce international

2020

Corruption is a practice that hinders development and can affect various activities, including international economic activities. It undermines the proper functioning of international trade requiring the need to fight against itThis study aims to highlight the existence of an anti-corruption legal framework implemented by international trade law which resists to corruption fight. This anti-corruption legal framework is materialized by the existence of tools that can be classified into two categories: tools belonging to the corpus of international trade rules and complementary tools provided by other legal rules very widely connected to international trade law, such as international arbitrat…

Hierarchically nested factor model from multivariate data

2005

We show how to achieve a statistical description of the hierarchical structure of a multivariate data set. Specifically we show that the similarity matrix resulting from a hierarchical clustering procedure is the correlation matrix of a factor model, the hierarchically nested factor model. In this model, factors are mutually independent and hierarchically organized. Finally, we use a bootstrap based procedure to reduce the number of factors in the model with the aim of retaining only those factors significantly robust with respect to the statistical uncertainty due to the finite length of data records.
