myExperiment workflow set only illustrates a subset of the usage of
the bioinformatics services, our experiment does reveal the necessity
of increasing the reusability and collaboration among bioinformatics
services.
8.4 SUMMARY
In this chapter, we have discussed the issue of the network analysis and
reuse of scientific workflows in a why-what-how sequence.
Why
. We have first reviewed the advances in social network
technology and especially its impact on science. Through a survey
on social network services for scientists, we find that a social
network has not only changed the way through which people do
personal networking and information sharing but also promoted
collaboration in a scientific community to the next level.
What
. We have then applied social network analysis methods to
mine and analyze the myExperiment workflow repository, focusing
on service usage patterns. The results indicate that services are
currently reused in an
ad hoc
style instead of a federated manner.
This observation suggests a need to help domain scientists dynami-
cally locate related services and workflows and reuse successful
processes to attain their research purposes.
How
. Based on a network-based model, we have presented a
ServiceMap framework, equipped with association rule mining
and matrix-based search algorithms, to provide a GPS-like support
for two types of service search queries: (1) Given a service I plan to
use, what other services are usually used together? and (2) Given
several services I want to use together, can I find an operation chain
to connect them, based on others' past usage?
