We model economic policy uncertainty (EPU) in the four largest euro area countries by applying machine learning techniques to news articles. The unsupervised machine learning algorithm used makes it possible to retrieve the individual components of overall EPU endogenously for a wide range of...

In this article, as part of the symposium on total factor productivity, Erwin Diewert of the University of British Columbia provides a comprehensive discussion of what is needed to develop reliable measures of total factor productivity in terms of output and the different classes of inputs. He...

It is generally acknowledged that the size-class distribution of enterprises in a country is an important characteristic of its economy. The EU countries are increasingly co-operating and adjusting to each other's needs in order to achieve optimal joint output. However, country differences -at...

In order to study the use of Twitter, it would be useful to be able to easily classify large volumes of messaging being used by Twitter users besides just in the traditional dimensions of positive and negative sentiment. For instance, in the space of social media marketing, it would be useful to...

This paper addresses the steep learning curve in Machine Learning faced by noncomputer scientists, particularly social scientists, stemming from the absence of a primer on its fundamental principles. I adopt a pedagogical strategy inspired by the adage "once you understand OLS, you can work your...

In this paper the use of Artificial Neural Networks (ANNs) in on-line booking for hotel industry is investigated. The paper details the description, the modeling and the resolution technique of on-line booking. The latter problem is modeled using the paradigms of machine learning, in place of...

Knowledge, as intellectual capital, has become the main resource of an organization, and the process of knowledge discovery, acquisition and storage is a very important one. Knowledge discovery can be easily realized through Data Mining, a Machine Learning technique, which allows the discovery...
