PROBLEM TO BE SOLVED: To improve the accuracy of estimating the position of the name of a place.SOLUTION: A POI data storage section 12 stores multiple pieces of POI data formed by associating the name of a POI with position information of the POI. A POI related-document extraction section 13 extracts document data including the name of the POI from the document data. A document analysis section 14 extracts the name of a place related to the POI data from the extracted document data, and calculates the number of times that the name of the place appears in the document data. A place-name position estimation section 15 calculates the position of the name of the place, by use of weight of the POI data and the position information of the POI. The frequency of appearance of the name of the place is the weight of the POI data with respect to the name of the place.
