Abstract

The invention relates to an identical entity attribute matching method in land utilization spatial data processing, in particular to an attribute matching method based on geographic ontology in land utilization spatial data processing. The problems that in an existing identical entity attribute matching method, matching is wrong easily, and the application range is limited are solved. The attribute matching method based on the geographic ontology in land utilization spatial data processing comprises the following steps that 1, the geographic ontology is constructed, wherein the geographic ontology comprises an ontology class library, an ontology relational base and a knowledge base, and the specific construction steps comprise 1.1 construction of the ontology class library, wherein the ontology class library comprises land classification, administrative division, space coordinate systems and element types; 1.2 construction of the ontology relational base, wherein the ontology relational base comprises an object relational base and a value relation base; 1.3 construction of the knowledge base; 2, entity attribute matching is carried out. The method is suitable for land utilization spatial data processing.

Description

technical field [0001] The invention relates to an attribute matching method of entities with the same name in land use spatial data processing, in particular to an attribute matching method based on geographic ontology in land use spatial data processing. Background technique [0002] In land use spatial data processing, attribute matching of entities with the same name is a very important link. Under the existing technical conditions, the attribute matching method of entities with the same name generally adopts the string matching method. The string matching method refers to finding one or all occurrences of a given string from the text, and then querying documents containing some key strings through simple superposition. Practice has shown that the string matching method has the following problems due to its own principle limitations: First, the string matching method cannot understand and deduce the semantics of the query, thus easily causing matching errors. Second, t...
