Most of these informations are not a address, especially some fuzzy description words like nearly, around, besides, front of … etc. Therefore, it makes the level of difficulte for people to locate the place exactly. In order to enhance the accuracy on locating fro offset Chinese address descriptioin, it’s important to extract the correct information by means of segment alogorythm, and then reconstruct the words into domain knowledge, transferring the words to coordinate, finally showing on the map. For the fuzzy geographic description processing, we analysis the location description first, extracting key words of geographic spatial information by segmenting and calculating the semantic of words. After segment, we make these key words reconstructor and connect in Ontology for linking the relation the geographic information into domain knowledge. We classify the elements of location description into 3 part first, POI, Direction, Distance. Normally POI will divid into 3 kinds, address, intersection and landmark, in our case, we just concider address, intersection, and Direction are concidering the landmark, go straight, azimuth and opposite. This Research mainly make machine do discrimination the direction of a offset address description and point to the correct position by using SWRL rules in geocoding part.
