In order to cross-fertilize ideas among scientists, the International Workshop on Complex Networks and Their Applications brings together researchers from different scientific communities working on areas related to complex networks. For the fourth edition of this annual event, seventy-six papers have been received from around the world. These contributions have been peer-reviewed from at least three independent reviewers to ensure the high quality of contributed material as well as adherence to conference topics. Among the thirty-one papers selected by the scientific committee for the workshop, nine contributions have been retained for submission to a thematic issue of Applied Network Science. These submissions are technically beyond the scope of the papers appearing in the workshop proceedings and include significantly new material. Following a new and independent review process, the papers have been selected for this thematic issue. These papers reflect the latest problems, advances, and diversity within the complex network community.
