Universal lossless compression of graphical data [PDF]

open access: yes2017 IEEE International Symposium on Information Theory (ISIT), 2017
Graphical data is comprised of a graph with marks on its edges and vertices. The mark indicates the value of some attribute associated to the respective edge or vertex. Examples of such data arise in social networks, molecular and systems biology, and web graphs, as well as in several other application areas.
