摘要： A database restructuring support system that enables a user to flexibly design the structure of a database after a restructure.A storage cost estimate unit 112 calculates storage cost before and after restructure by using catalog information included in a database 122. In the case of calculating the storage cost of the restructure, tuples of a new schema is calculated and the storage cost is calculated by using the tuples. The access cost estimate unit 113 uses the catalog information and the log DB 121 included in the database 122 to calculate each access cost before and after restructure. In the case of calculating the access cost after restructure, the number of types of values of an attribute in the new schema is calculated to calculate the access cost by using the number of types. The integrated cost estimate unit 111 calculates the integrated cost by integrating the access cost and the storage cost.

摘要： A place name information extraction apparatus in which not only a place name expression appeared in a text is extracted but also the type of the extracted place name expression can be judged, and a place name information extraction method of the apparatus, and a storing medium stored place name information extraction programs of the method, and a map information retrieval apparatus used the place name information extraction apparatus are provided. The place name information extraction apparatus provides a place name expression detecting means that detects a place name expression appeared in a text and its position appeared the place name expression in the text, and a place name type judging means that judges a place name type, which signifies a meaning role of the place name expression appeared in the text, by analyzing before and after the position appeared the place name expression in the text.

摘要： An information delivery server and clients, which can deliver geographic information to a user based on a reaching possibility such as a physical distance or time from a place such as a location of the user or a place where the user had an interest, is provided. A user inputs his/her interested place information and a range condition at a place condition inputting means. A user managing means manages user IDs and identifies a user and attaches the user ID of the user to the inputted information, and stores them in a user interested place database. A map information retrieving means retrieves a map database under the conditions of the interested place information and the range condition storing in the user interested place database, and obtains information such as a list of building names, and place names, and so on within the range from the map database. A document database retrieving means retrieves a document database by making the obtained building names and place names as keywords, and obtains a document to be delivered to the user. And the obtained document is delivered to the user from a document informing means.
