ABSTRACT
It is common for software practitioners to look for experts on online chat platforms, such as Discord. However, finding them is a complex activity that requires a deep knowledge of the open source community. As a consequence, newcomers and casual participants may not be able to adequately find experts willing to discuss a particular topic.
Our paper describes a bot that provides a ranked list of Discord users that are experts in a particular set of topics. Our bot uses simple heuristics to model expertise, such as a word occurrence table and word embeddings. Our bot shows that at least half of the retrieved users are indeed experts.

Robustness measure of hybrid intra-particle entanglement, discord, and classical correlation with initial Werner state
Quantum information processing is largely dependent on the robustness of non-classical correlations, such as entanglement and quantum discord. However, all the realistic quantum systems are thermodynamically open and lose their coherence with time ...
Super-quantum discord in ferromagnetic and antiferromagnetic materials
AbstractSuper-quantum discord is an extension of the quantum discord concept where weak measurements are made instead of projective measurements. We study the temperature behavior of the super-quantum discord for two real magnetic materials. We extract ...
Quantum discord in spin systems with dipole---dipole interaction
The behavior of total quantum correlations (discord) in dimers consisting of dipolar-coupled spins 1/2 are studied. We found that the discord $$Q=0$$Q=0 at absolute zero temperature. As the temperature $$T$$T increases, the quantum correlations in the ...
