Port clusters as an opportunity for optimizing small-scale LNG distribution chains: an application to the Mediterranean case

Small-scale LNG logistics chains have become more important for delivering LNG via shipping from large supply terminals to customers via satellite terminals. An ideal application of small-scale LNG logistics chains is in the Mediterranean basin, where the maximum distance between two ports is always less than two thousand miles. Focusing on a Tyrrhenian application case, this study develops a modeling tool capable of defining the optimal configuration for a small-scale LNG distribution networ...

Recency, Popularity, and Diversity of Explanations in Knowledge-based Recommendation

Modern knowledge-based recommender systems enable the end-to-end generation of textual explanations. These explanations are created from learnt paths between an already experience product and a recommended product in a knowledge graph, for a given user. However, none of the existing studies has investigated the extent to which properties of a single explanation (e.g., the recency of interaction with the already experience product) and of a group of explanations for a recommended list (e.g., t...

Consumer Fairness in Recommender Systems: Contextualizing Definitions and Mitigations

Enabling non-discrimination for end-users of recommender systems by introducing consumer fairness is a key problem, widely studied in both academia and industry. Current research has led to a variety of notions, metrics, and unfairness mitigation procedures. The evaluation of each procedure has been heterogeneous and limited to a mere comparison with models not accounting for fairness. It is hence hard to contextualize the impact of each mitigation procedure w.r.t. the others. In this paper, ...
