The volume contains the proceedings of the KOMEEO (Knowledge
Organization and Management in the domain of Environment and Earth
Observation) international conference, organized in the field of the
European ERA-PLANET (The European Network for observing our changing
Planet) H2020 program. Papers present research projects and experiences
related to different aspects of organizing knowledge in the
environmental domain, which nowadays is receiving great attention from
the European Union. In particular, they address topics related to
Knowledge Organization Systems (KOSs), to their application in specific
contexts, to the extraction of metadata, to the achievement of semantic
interoperability.
