The semantic parsing for GML based on SIDB

摘要：

GML data is widely used for model building,data exchanging,etc.The GML data parsing is the base of handling other operation of GML.The parsing technology of XML can be used for GML parsing.But the XML parsing technology is deficient in parsing semantic information on geography information.This paper tries to build a semantic information database (SIDB) of GML and design GML core schema-based parsing engine which based on SIDB.Ultimately actualize GML data parsing.The results of the study are verified by GML test data in the paper.And more,this study provides a new way to parsing semantic information in other fields.
