We present the Koblenz Network
Collection (KONECT), a project to collect
network datasets in the areas of web science, network science and
related areas, as well as provide tools for their analysis. In the cited
surprisingly large number of very heterogeneous data can be modeled as
networks and consequently, a unified representation of networks can be used
to gain insight into many kinds of problems. Due to the emergence of the
World Wide Web in the last decades many such datasets are now openly available.
The KONECT project thus has the goal of
collecting many diverse network datasets from the Web, and providing a
way for their systematic study.
The main parts of KONECT are (1)~a collection of
over 160 network datasets, consisting of directed, undirected,
unipartite, bipartite, weighted, unweighted, signed and temporal
networks collected from the Web, (2)~a Matlab toolbox for network
analysis and (3)~a website giving a compact overview the various
computed statistics and plots. In this paper, we describe KONECT's
taxonomy of networks datasets, give an overview of the datasets
included, review the supported statistics and plots, and briefly discuss
KONECT's role in the area of web science and network science.
