In scientific research, reproducibility and replicability are requirements to ensure the advancement of our
body of knowledge.
T
his holds true also for VGI
-
related research and studies. However, the
characteristics
of VGI suggest particular difficulties in
ensuring
reproducibility and replicability
. In this
paper,
we aim to examine the current situation in VGI
-
related research
,
and identify strategies to ensure
realization of its full potential. To do so, we first
investigate
the different aspects of reprod
ucibility and
replicability
and their impact on
VGI
-
related research
. These impacts are different depending on the
objectives
of the study. Therefore
, we examine the
study
focus of VGI
-
related research to assess the
current body of research
and structure o
ur assessment
. Th
is work is
based
on a rigorous review of the
elements of reproducibility and a systematic mapping and analysis
of
58
papers on the use of VGI in the
crisis management field. Results of our investigation show that reproducibility issues related to data are
a
serious
concern
, while reproducibility issues related to analysis methods and processes face fewer
challenges. Howe
ver, since most studies still focus on
analyzing
the source data, reproducibility and
replicability are
still an unsolved problem
in VGI
-
related research. Therefore, we
show initiative
s
tackling
the problem, and
finally formulate strategies to improve the
situatio
