Relation between the stay place and conduct classification of the user, is extracted from position information past record. Conduct feature extraction device 300 conduct similar type memory section includes with 202 and conduct feature extraction section 302. Conduct similar type memory section 202 remembers the stay point information 212 which includes the information which shows the order which stays in the particular stay point the stay point of the 1st conduct base classification which corresponds to 1st conduct classification and the plural stay points which include with the stay point of the 2nd conduct base classification which corresponds to 2nd conduct classification concerning respectively. Conduct feature extraction section 302, stay point information 212 on the basis of, the stay point of 1st conduct base classification and either among the stay points of 2nd conduct base classification starting point, extracts the chain of the stay point which designates each of them as terminus, on the basis of the conduct base classification of starting point and terminus, it calculates concerning the respective stay point which is included in the chain of the stay point which is extracted stay point degree of association related extent of the stay point and conduct classification is shown, outputs.
