SWEET Ontologies

SWEET ontologies are written in the OWL ontology language. OWL is an XML language being adopted as a standard by the W3C. SWEET ontologies can be viewed using Internet Explorer 5 (or later) or Netscape 7. More specialized OWL-specific tools are available such as SWOOP or Protege.

SWEET 1.1 ontologies available

 

SWEET 2.0 Beta expanded ontologies available

 

Semantic Web for Earth and Environmental Terminology (SWEET)

Home    Ontologies    Products    Links

This project provides a common semantic framework for various Earth science initiatives. The semantic web is a transformation of the existing web that will enable software programs, applications, and agents to find meaning and understanding on web pages.  SWEET developed these capabilities in the context of finding and using Earth science data and information.

Planetary Ontologies

A web site for sharing ontologies in the Earth and Space Sciences

Purpose and Scope

• To facilitate the use, re-use, development, evolution, alignment and merging of ontologies by a community of best-practices in the broad fields of Earth and Space Sciences.
• To enable collaborative use and discussion of ontologies by practitioners.

4. SWEET ontologies
The SWEET ontologies include several thousand
terms, spanning a broad extent ofEarth system science
and related concepts (such as data characteristics). To
support such a large collection and adhere to the guiding
principles, the concepts are divided, where possible, into

orthogonal dimensions or facets in support ofreductionism.
The primary ontologies are shown in Fig. 1 and
described in Section 4.1. Each box represents a separate
ontology, and a connecting line indicates where major
properties are used to define concepts across ontology
spaces. The unifying ontologies (such as phenomena) are
generally holistic, in derivation. For example, a hurricane
is associated with particular coastal areas, and is
characterized by high winds, rainfall, flood impacts, etc.
