Recommender Systems for Large-Scale Social Networks: A review of challenges and solutions
TL;DR: This work reviews the various facets of large-scale social recommender systems, summarizing the challenges and interesting problems and discussing some of the solutions.
Journal ArticleDOI
Efficient task replication and management for adaptive fault tolerance in mobile Grid environments
TL;DR: An efficient scheme based on task replication, which utilizes the Weibull reliability function for the grid resources so as to estimate the number of replicas that are going to be scheduled in order to guarantee a specific fault tolerance level for the Grid environment is presented.
Proceedings ArticleDOI
Content vs. context for sentiment analysis: a comparative analysis over microblogs
TL;DR: This work introduces a method that relies on two orthogonal, but complementary sources of evidence: content-based features captured by n-gram graphs and context-based ones captured by polarity ratio, guaranteeing high effectiveness and robustness in the settings the authors are considering.

COVID-19 detection from chest X-Ray images using Deep Learning and Convolutional Neural Networks
TL;DR: Several state-of-the-art pre-trained convolutional neural networks were evaluated as of their ability to detect infected patients from chest X-Ray images and demonstrate that the classification performance can reach an accuracy of 95% for the best two models.
