Abstract

In previous geographic information inquiry, query condition is either fixed in program or providing an SQL inquiry mode for users. The former condition is unalterable while the latter demands users to be equipped with certain SQL query language knowledge. The article introduces how to use a rule engine to make inquiries through simple combination between natural semantic modules with the support of rule base. First, users formulate query plans through simple combination between natural language modules according to their own demands. Then, users deliver the query scheme to the rule engine for reasoning & matching, find the correct matching rule, and execute this rule. Finally, execution results are returned to users.
