Traffic information query system and traffic information query method
First Claim
1. A map knowledge base generating section, comprising:
- an attribute value extracting unit for extracting attribute values corresponding to attributes of the roads and traffic points from an electronic map;
an attribute value spatial relationship forming unit for forming spatial correspondence relationship among attribute values of the roads and traffic points; and
a combining unit for combining attributes of roads and traffic points and attribute values corresponding to the attributes, spatial correspondence relationship among the attribute values and an axiom based on the spatial correspondence relationship so as to form a map knowledge base.

Abstract
The invention provides a map knowledge base generating device and a method thereof, and a traffic information query system and a method thereof. The traffic information query system, comprises: a map knowledge base generating section for generating knowledge related to attributes of roads and traffic points, attribute values corresponding to the attributes, and spatial information of the attribute values based on an electronic map so as to form a map knowledge base; and a traffic query processing section for receiving and analyzing a query form a user terminal, decomposing the query if it is determined that the query can be decomposed according to the map knowledge base, and searching a traffic information database according to the decomposed the query request.
