Real-world entities often interconnect with each other through explicit or implicit relationships to form a complex network. Examples of complex networks are found in many fields of science such as biological systems, engineering systems, economic systems as well as social systems. In line with SITIS tradition of promoting interdisciplinary research, the international workshop on Complex Networks and their Applications aims at bringing together researchers and practitioners from different science communities working on areas related to complex networks. The workshop targets two types of contributions from prospective authors: contributions dealing of theoretical tools and methods to solve practical problems as well as applications solved by tools from network sciences. Both contributions should stimulate interaction between theoreticians and practitioners.
