Description:
AnnoTerra is a Semantic Web Application that presents enhanced Earth
science newsfeeds by making focused semantic searches on NASA knowledge
catalogs using concepts and relationships of the Earth science realm.
At present, AnnoTerra processes newsfeeds from the NASA Earth Observatory
by extracting meaningful keywords. These keywords are then used to
perform ontology based semantic searches in the Global Change Master
Directory (GCMD) for relevant resources. The results retrieved are
subsequently mapped to an ontology of the Earth Observing System (EOS)
ClearingHOuse (ECHO) and a new search is performed for corresponding
datasets in the ECHO catalog. By creating an ontology for the GCMD and
ECHO, and a equivalence between the two, we've created a semantic
unification of Earth science resources registered in GCMD and data
collections registered in ECHO.
The project name, AnnoTerra, is derived from Annotated Terrestrial
Information, with the idea of enhancing existing data sources with extra
information.
