Abstract

A storage medium recording an information reacquisition procedure generation program causing a computer to execute a process of generating a reacquisition procedure for reacquiring information, the information reacquisition procedure generation program causing the computer to execute a method comprising: reading a message history from a storage unit storing the message history recording a series of messages exchanged to and from a device providing information until the information is provided; generating a message transitional relationship with respect to the information by extracting a parent-child relationship between the respective messages contained in the series of messages based on the series of messages until the information contained in the read message history is acquired as well as by combining the same or similar messages of the series of messages into one; and outputting the reacquisition procedure with respect to the information based on the generated transitional relationship.

Claims

1. A storage medium recording an information reacquisition procedure generation program causing a computer to execute a process of generating a reacquisition procedure for reacquiring information, the information reacquisition procedure generation program causing the computer to execute a method comprising:

reading a message history from a storage unit storing the message history recording a series of messages exchanged to and from a device providing information until the information is provided;

generating a message transitional relationship with respect to the information by extracting a parent-child relationship between the respective messages contained in the series of messages based on the series of messages until the information contained in the read message history is acquired as well as by combining the same or similar messages of the series of messages into one; and

outputting the reacquisition procedure with respect to the information based on the generated transitional relationship.

2. The storage medium recording an information reacquisition procedure generation program according to claim 1, wherein the transitional relationship is generated by analyzing a syntax of the message recorded in the message history, combining the messages having same or similar specific data contained therein into one and extracting the messages as a node as well as by extracting a parent-child relationship between the nodes as an edge, and a tree structure using the node and the edge is treated as a message transitional relationship with respect to the information.

3. The storage medium recording an information reacquisition procedure generation program according to claim 2, wherein the transitional relationship is generated such that the node extracted is sequentially set to a target node, the messages issued before a target message contained in the target node are sequentially analyzed, an issuer candidate determined as an issuer issuing the target message is retrieved, and a process of setting a node containing the retrieved issuer candidate to a parent node of the target node is repeated to set the parent node to all the extracted nodes.

4. The storage medium recording an information reacquisition procedure generation program according to claim 3, wherein the transitional relationship is generated such that information common to other messages such as a URL, a request method, a response status code, and a response media type contained in the message is extracted as the specific data.

5. The storage medium recording an information reacquisition procedure generation program according to claim 2, wherein the transitional relationship is generated such that, among a plurality of the messages classified in the same node, a message is selected as a representative message;

and

as the reacquisition procedure, a procedure for reacquiring the representative message is outputted.

6. The storage medium recording an information reacquisition procedure generation program according to claim 2, wherein the information reacquisition procedure generation program causes the computer to further execute a method comprising:

generating a relation diagram representing the transitional relationship as a tree structure using the node and the edge and presenting the user as well as modifying the transitional relationship and the relation diagram based on a modification instruction when the user enters the modification instruction.

7. The storage medium recording an information reacquisition procedure generation program according to claim 6, wherein the transitional relationship and the relation diagram are modified such that when the node is selected and an instruction for modifying the transitional relationship between the nodes represented by the edge is entered, the parent-child relationship between the nodes including a descendant node with respect to the node selected is modified.

8. The storage medium recording an information reacquisition procedure generation program according to claim 2, wherein the reacquisition procedure is outputted as a reacquisition program causing the computer to execute a series of processes of sequentially following the tree structure starting at a root node thereof until reaching the node containing the message for acquiring target information, generate a request message based on a representative message of the node, and sequentially send the generated request message.

9. The storage medium recording an information reacquisition procedure generation program according to claim 8, wherein the reacquisition procedure is outputted as a reacquisition program causing the computer to execute a series of processes of extracting a response message corresponding to the request message from the message history, extracting specific data from the response message, defining an error process of determining whether or not the specific data is contained in a response from the request message defined by the reacquisition procedure, and executing the error process.

10. An information reacquisition procedure generation apparatus generating a procedure for reacquiring information, comprising:

a storage unit storing a message history recording a series of messages exchanged to and from a device providing specific information until the information is provided;

a reading unit reading the message history from the storage unit;

a transitional relationship generation unit generating a transitional relationship of a message with respect to the information by extracting a parent-child relationship between the respective messages contained in the series of messages based on the series of messages until the information contained in the read message history is acquired as well as by combining the same or similar messages of the series of messages into one; and

a reacquisition procedure output unit outputting a reacquisition procedure with respect to the information based on the generated transitional relationship.
