Market research: visualizing the shadow economy

In light of our recent post on credit card ownership, we used once again Tableau to explore data related this time to analyse and visualize the shadow economy. The shadow economy is the part of the economy that runs “off the records”.

Hospitality: why it’s important to answer online customer reviews

Social media is an unmissable way to connect customers and firms. It has also become a privileged channel to raise complaints and engage in positive and negative word-of-mouth. In today’s article we propose to analyse one aspect of electronic word-of-mouth (eWOM) which has been recently dealt with in a marketing research published in the Journal of Interactive Marketing by Jie Sheng (University of Bristol).

Marketing research: the 4 dimensions of online customer experience

Seeing a paper on online customer experiences published in the Journal of Marketing was therefore an exciting event for me. It’s entitled “Creating Effective Online Customer Experiences” and is authored by 3 scholars : Alexander Bleier, Colleen M....

Recommendation systems: a scientific investigation of user inaction

One of the most interesting researches at RecSys 2018 was for me the paper on user inaction by Qian Zhao, Martijn Willemsen, Gediminas Adomavicius, F. Maxwell Harper and Joe Konstan (full title: “Interpreting User Inaction in Recommender Systems“). We are so focused on interpreting signals that we often forget to take the absence of signal into account. Yet, as this paper shows, lack of information is already a piece of...

What can you discover about filter bubbles when you analyse datasets with billions of tweets over a 8-year period ? Some very interesting results for sure.  In particular that you don’t need algorithms to stay within an echo chamber and that bridging echo chambers comes at a price. This contributes to the ongoing discussion on the very existence of algorithmic filter bubbles. Introduction Garimella et al. (2018) studied...
