We expect Soft Computing and Electrical Engineering to be indexed in Web of Science (Clarivate Analytics) and Scopus (Elsevier).
Publisher sends all of its published materials to the indexing services. But please note that DBLP, Scopus, Engineering Village, EI Compendex, CPCI(Web of Science), etc., are all entirely separate entities from Publisher. As such, we cannot guarantee that a certain proceedings volume content will pass their review process – or, even if it does pass the review process, when exactly that volume will be indexed. They all have their own guidelines for acceptance, independent of Publisher's influence.
