  The experience data reading unit 44 sequentially reads the experience data stored in the experience data storage unit 40 and passes the read experience data to the relevance calculation unit 46. The relevancy calculation unit 46 calculates the relevance between the POI data and the experience data based on the similarity between the explanatory text of the POI near the current position and the experience content of the experience data read from the experience data storage unit 40. To do. As a method for obtaining the similarity between the sentence describing the experience contents and the POI explanation sentence, for example, the similarity can be obtained based on the frequency with which a certain keyword appears in a document to be compared. As a specific algorithm, there is a TF / IDF method. In the TF / IDF method, when a characteristic keyword in a document is extracted and two documents to be compared are characterized by the same keyword, it can be recognized that there is similarity between the documents.

  The related experience data search unit 42 obtains, as related experience data, experience data whose similarity calculated by the relevancy calculation unit 46 is greater than a predetermined threshold. In this specification, the similarity between POI and experience data is greater than a predetermined threshold is called “POI and experience data are related”, and experience data related to POI is called “related experience data”. The POI associated with the experience data is referred to as “related POI”.

  FIG. 6 is a diagram illustrating an operation of the map display system 1 according to the first embodiment. The terminal device 10 detects the current position by the terminal position detector 18 (S10), and transmits data of the detected current position to the center device 30 (S12). When the center device 30 receives the current position data transmitted from the terminal device 10 (S14), the center device 30 searches the POI data storage unit 34 to determine whether the POI exists within a predetermined range including the current position of the terminal device 10.
