A Semantic Categorization of Hydrological Domain Based on Formal Concept Analysis

doi:10.13485/j.cnki.11-2089.2014.0130

Abstract

Abstract:

The reasonableness of the geographic information categorization system has a direct impact on the interaction and sharing of geographic information. A method is proposed to explore the hierarchical semantic categorization of the fundamental geographic information from GB/T 13923-2006 in China. First，we selected a set of meta-properties to extract the semantic of geographical entity, and then construct the formal concept context and Hasse Diagram based on Formal Concept Analysis, finally, we implemented Lattice-tree transforming method of generating the hierarchical semantic classification of hydrological domain, which possessed the direct semantic inclusion. The method eliminates the overlapping concept and crossing semantic among the original classification system, which is a useful complement to the existing classification methods. As well as merits and limitations are discussed.

Key words: Formal Concept Analysis, Lattice-tree transforming method, Geographic information, Hydrological Category, Categorization
