Abstract: A method includes: first identifying, from among one or more items included in a source code of a program, a first item used for storing data input to the program or data output by the program; associating, for each of predetermined ranges configuring the source code, an index value, based on a number of the first items referenced in the relevant predetermined range and the number of times the first item is referenced in the relevant predetermined range, with the relevant predetermined range; and outputting an association result of the index value for each of the predetermined ranges.

Abstract: A computer-readable recording medium storing therein a test data generating program to be executed by a computer, the program causing the computer to: generate, for each of a plurality of path conditions obtained by repeatedly performing symbolic execution, a simplified path condition by substituting a fixed value for a first symbolic variable included in the path condition; calculate, for each the simplified path condition, a value of the symbolic variable that satisfies the simplified path condition; generate test data including the values of the symbolic variable, the fixed values, and path conditions not subjected to simplification; and remove duplicative data from the test data that corresponds to a same path condition.

Abstract: The right for correlating a region or an existence with a virtual region in a virtual world structured in for example the Internet is sold, bought, lent, or rented. For example, when a buyer bought a virtual region from a seller, the virtual region of the seller is correlated with a virtual region of the buyer in a link method, a paste method, or a projection method.

Abstract: A server apparatus 10 for applying a point by which a service can be received in response to an amount of said point to be used in a Web site, comprises files 23/24 for storing a banner advertisement, and a point producing unit 14 for determining a point number which is displayed on the banner advertisement. This server apparatus 10 is further arranged by a Web control unit 11 for displaying the banner advertisement attached with the point number on a Web page, and also a user data managing unit 12 for managing a point number gained by a user. The server apparatus 10 determines a point number to be displayed on a banner advertisement with reference to personal information of a user, or a point number gained by the user.

Abstract: This invention is to present specific information necessary for maintenance of programs in an information system. This program analysis method includes: storing an entity that is an information unit as an object of a processing in a program into a relation table in association with an event affecting a processing for the entity; calculating importance degrees of the events by using data stored in the relation table; and identifying an event affecting a processing for a specific entity by using the data stored in the relation table, and calculating an influence degree of the specific entity by using the importance degree of the identified event. Because the user can grasp the influence degree of the entity, it becomes easy to grasp how much the update of the entity affects other portion in the information system.

Abstract: In a computer for executing a process in accordance with a workflow diagram generation program, a path extractor extracts processing paths from program information indicating the procedure of a business program, and generates path information indicating read and update processes performed in the individual processing paths and operation screens displayed in the processing paths. A path associator associates each transition relation, which is the relation between two data sets successively updated, with a processing path of which the data set to be read agrees with the data set of the transition source and of which the data set to be updated agrees with the data set of the transition destination. A flow diagram generator generates a workflow diagram which indicates the data sets as nodes and the transition relations as links and in which information indicating the operation screens displayed in the processing paths are annexed to the corresponding links.

Abstract: Situated information (SI) is created by adding situation information, which expresses by 5W1H a situation where an information resource becomes effective, to the information resource, and the SI is registered to an SI memory unit. Then, information resource which has situation information fitting the current situation is selected and presented to a user.

Abstract: A device presents selling information about a virtual region of a selling object in a virtual world. An accepting device accepts a message that represents that a buyer will buy the virtual region of the selling object and information about the buyer. An executing device transfers the right for correlating a processing object with the virtual region of the selling object to the buyer, using at least one of a virtual existence and a virtual region in the virtual world, a virtual existence and a virtual region in another virtual world, and a real existence and a real region in a real world as the processing object. The correlating device correlates identification information of the processing object with identification information of the virtual region of the selling object.

Abstract: A service database stores a set of area information and a service program for each individual service. When position information of a mobile station and service selection information are received, the service database is searched to retrieve a service program specified by the service selection information and corresponding area information. When the mobile station is present in the area represented by the area information, the service program is executed to provide a service to the mobile station.
