| Περίληψη: | The trend of opening government data, in order to
be used for scientific, commercial and political purposes, has
resulted in the development of numerous e-infrastructures
providing public sector information (PSI). The big investments
that have been made in this direction necessitate a deeper
understanding and assessment of the value they produce. This
paper presents a methodology for evaluating PSI einfrastructures,
which is based on the estimation of multiple
value models corresponding to their main stakeholder groups:
data users and data providers. Each value model consists of
several value dimensions and their corresponding value
measures, organized in three levels (associated with efficiency,
effectiveness and future behaviour), and also the relations
among them. The proposed methodology allows a
comprehensive assessment of the various types of value
generated by a PSI e-infrastructure for each stakeholder
group, and also the interconnections among them. This enables
a better understanding of the whole value generation
mechanism and a rational definition of improvements
priorities. |
