In order to solve the existent problem of complexity of classification standard and inconstancy of combining geomorphologic factors in geomorphologic classification system, a Geomor-Onto(geomorphology ontology) is built up to describe complicated geomorphy classification problem. With the formal analysis to the semanteme of geomorphic conception, this paper proposes a logic structure of Geomor-Onto...
As ontology has become a convenient vehicle for domain knowledge and metadata, it is used for realizing information sharing at semantic level in geoscience. Building geo-ontology is a systematic engineering and requires collaborative work, while there is a lack of ontology edit tools supporting collaborative work. Since Wikis are cooperative tools for easy writing and sharing of content and semantic...
