In this embodiment, an example will be described in which new software is realized by integrating software components realized as XML Web services, and software components are appropriately integrated.

Embodiment 1

 First, the configuration of the integrated service providing system according to the present embodiment will be described. FIG. 1 is a block diagram showing an example of a configuration of an integrated service providing system according to the present embodiment. Here, for simplicity of explanation, an example is shown in which one client and three software component providing servers are provided. As shown in Fig. 1, the integrated service providing system according to the present embodiment is composed of an integrated service providing server 1, three software component providing servers 2A, 2B, 2C, and a client 3. Each is connected via network 4.

 In the present embodiment, the integrated service providing server 1 appropriately selects and combines software components in response to a request from the client 3, and converts the selected software components into software component providing servers 2A, 2B, 2 An example of acquiring from the corresponding software component providing server of C and executing it will be described.

Next, the configuration of the integrated service providing server according to the present embodiment will be described. FIG. 2 is a block diagram showing an example of a configuration of the integrated service providing server according to the present embodiment. As shown in FIG. 2, the integrated service providing server 1 according to the present embodiment includes a client interface unit i 01, a software determination unit 102, , Software search section 103, software registration section 104, capability 能力 operation check section 105, rule engine section 106, priority order determination section 1◦7, and performance management section 108 , A performance acquisition unit 109, a software execution unit 110, a simulation unit 111, and a billing calculation unit 112.

 Hereinafter, the operation of the integrated service providing system according to the present embodiment will be described. In order to integrate software components and provide them to users, it is necessary to register the original software components. Here, the operation of software component registration will be described. The registration of the XML Web service consists of the registration of the XML describing the content of the service and, in the case of the fee-based service, the payment procedure contract procedure.

 First, the operation of service registration in the integrated service providing system according to the present embodiment will be described. Software components that execute the XML Web service

By registering in the software registration unit 104 of the integrated service providing server 1, services can be called from the integrated service providing server 1. Some software components provided by the Web service may be provided with the same free service as free software.

This service registration only.

 Next, the operation of service registration using the directory service will be described. In the XML Web service, there is a telephone directory server on the Internet called a directory service for searching services, and service registration can be performed for this. Then, by reregistering the contents registered in the directory service in the software registration unit 104 of the integrated service providing server 1, these services can be called. Here, when the integrated service providing server 1 performs its own registration, it is possible to take into account, as the case may be, a constraint description that does not fall into the category of a standard directory service on the Internet.

Next, the service registration operation of the fee-based XML Web service will be described. In this case, the payment method contract procedure is performed at the same time. In the integrated service providing system according to the present embodiment, a contract service (not shown) connected to network 4 is provided. The server plays this role. A software component provider wishing to register a software component first accesses the contract server. The contract server has a description about the fee. The terms of the fee shall consist of the base fee, incentive fee, and penalty fee described below. A document that describes the method of measuring this charge and the method of paying the payment is presented, and upon agreement with the software component provider, the contract software settings such as the method of payment and notification, etc. And register software components using the XML Web service. At this time, metadata of the software component to be registered is also registered. This procedure is performed by the software component provider, a third-party registration agent, and software components.

 One of the features of the integrated service providing system according to the present embodiment is that it is recommended to register a plurality of software components corresponding to one input format. This is important for system optimization and stability.

 Next, the operation of user registration in the integrated service providing system according to the present embodiment will be described. A user who wishes to use the integrated service providing system accesses a user registration server (not shown) connected to the network 4 using the client 3 and performs user registration. After the user agrees on the payment method described below, the user inputs the user ID, password, payment method for the usage amount, etc., and the registration is completed. Here, the user does not necessarily represent the end user, but when another service accesses the integrated service providing server 1, it represents the service provider.

 Next, an overview of the operation of integrated service providing server 1 according to the present embodiment will be described. FIG. 3 is a flowchart showing an example of the operation of the integrated service providing server. First, a user who is confirmed to be a valid user by inputting the user ID and the password transmits a request message using the client 3. The request message is a description of the functions and arguments that the user desires.

Next, the client interface unit 101 of the integrated service providing server 1 receives the request message from the client 3. FIG. 4 is a diagram showing an example of a request message in the XML format. The request message example shown in Fig. 4 is for requesting a delivery date search of 800 pieces of aluminum with a thickness of 100 mm. Here, the function is It is a rope, and its arguments are material, thickness, and number.

 Next, the client interface unit 101 analyzes the received request message (S 1). Analysis is performed by recognizing the structure of XML using software called XML parser, and extracting required functions and arguments. At this time, access information such as the time the request was input, the user ID, and the address of the access source is also obtained.

 If the format of the request message is not correct (S2, No), the client interface unit 101 notifies the client 3 of an error message (S8), and ends this flow. On the other hand, if the format of the request message is correct (S2, Yes), the client interface unit 101 outputs the requested function, argument, and access information to the software determination unit 102 as request parameters. The software determination unit 102 outputs the required parameters to the software search unit 103.

 Here, the software registration unit 104 will be described in detail. The software registration unit 104 includes a function flow DB (database) and a component DB. FIG. 5 is a diagram showing an example of a functional flow DB. As shown in FIG. 5, the function flow DB is composed of an integration function, a component function 1, a component function 2, and the like, and is managed by a flow ID. Fig. 5 shows an integrated function composed of two component functions as an example, but there is also an integrated function composed of multiple component functions. The component function is a function of the software component alone. An integrated function is a function obtained by integrating software components. A function flow is a representation of an integrated function by its component parts. At the time of operation, it is more efficient and reliable to know in advance which component function will be used to fulfill the request. Therefore, the administrator of the integrated service providing server 1 must The combination is stored in the function flow DB as a function flow. For example, in FIG. 5, when the integrated function is a delivery date search, the part function 1 is a delivery date search and the part function 2 is a price search.

 FIG. 6 is a diagram showing an example of the component DB. As shown in FIG. 6, the component DB is composed of a component function, a provider, a provider network ID, and the like, and is managed by the component ID.

Next, the software search unit 103 implements the software capable of performing the requested function. The software is searched from the software registration unit 104 (S3). As a result of the search, if the requested function is an integrated function (S4, Yes), after executing the integrated function (S5), the process shifts to processing S6. The execution of the integrated function of the process S5 will be described in detail later with reference to a flowchart of FIG. On the other hand, if the requested function is a component function (S4, No), after execution of the component function (S7), the process proceeds to processing S6. The execution of the component function of the process S7 will be described in detail with reference to a flowchart of FIG. 11 described later.

 After the execution of the integrated function (S5) or the execution of the component function (S7), the software execution unit 110 sends the execution result as a response message to the request as a response message to the client 3 via the client interface unit 101. Is notified (S6), and this flow ends.

 FIG. 7 is a diagram showing an example of an answer message in the XML format. The response message example shown in Fig. 7 'indicates that the delivery date is 4 days as a result of the delivery date search for the request.

 Here, when the result of evaluation regarding the quality of service is obtained from the client 3, the result obtaining unit 109 obtains the evaluation result. In this case, the user who has obtained the execution result transmits the evaluation result regarding the quality of service to the integrated service providing server 1 using the client 3. The result acquisition unit 109 acquires the evaluation results from the three clients via the client interface unit 101 and outputs the result to the result management unit 108.

 Next, the operation of executing the integrated function of the process S5 will be described in detail. FIG. 8 is a flowchart showing an example of the operation of executing the integrated function. First, the software search unit 103 outputs, to the software determination unit 102, a function flow candidate that can execute the integrated function obtained by the search. The software determining unit 102 outputs the request parameter and the function flow candidate to the priority determining unit 107. The priority order determining unit 107 calculates which function flow is optimal using the past results, and determines the execution priority of the function flow candidate (S11).

Here, the results are explained. Performance is the accumulation of evaluation results of function flows executed in the past and evaluation results of software components executed in the past. . The evaluation results include an evaluation result generated by the software execution unit at the time of execution and an evaluation result generated by the client 3 who has been provided with the service. The evaluation result generated by the software execution unit indicates whether the execution was successful or failed, whether the software component providing server could be accessed when execution was desired, and whether the input was optimal for the software component. Errors that occur in software components during execution, performance such as speed, etc.

 The performance management unit 108 calculates the executed function flow and the score of the executed software component based on the evaluation result generated by the software execution unit and the evaluation result generated by the client 3. The performance management unit 108 includes a functional flow performance DB for managing performance on a functional flow basis and a software component performance DB for managing performance on a software component basis. .

 FIG. 9 is a diagram showing an example of a functional flow record DB. As shown in Fig. 9, the functional flow record DB is composed of integrated functions, required parameters, selected parts 1, selected parts 2, execution success / failure, points, execution time, and the like, and is managed by case ID. FIG. 10 is a diagram showing an example of the software component record DB. As shown in FIG. 10, the software component performance DB is composed of component functions, required parameters, selected components, execution success / failure, score, execution time, and the like, and is managed by a case ID. The results in FIGS. 9 and 10 may include execution results.

Next, an example of the operation of determining the priority of execution of the functional flow will be described. First, the performance calculation unit 107 extracts, from the performance management unit 108, the performance results of the function flows having the request parameters similar to the current request parameters. This prevents selection of a function flow that has contributed to a service unrelated to this request. Next, by performing a correlation analysis using the score of the functional flow and the score of each software component that is included in the actual performance of the extracted functional flow, the contribution of each software component to the actual performance of the extracted functional flow Is calculated. The sum of the contributions is calculated as the priority of the functional flow, the priority is assigned according to this priority, and the functional flows up to the specified order are regarded as one candidate for the functional interface. Output to the key decision unit 102. Execution of the function flow is performed in order from the one with the highest priority. Next, the software determination unit 102 passes the request parameter, the function flow candidate, and the priority to the software search unit 103. If there is no unexecuted function flow (S12, No), this flow ends. On the other hand, if there is an unexecuted function flow among the passed function flows (S12, Yes), the processing shifts to processing S13. Here, this is included when there is no corresponding function flow in the processing of S3 and when there is no unexecuted function flow.

 Next, the software search unit 103 decomposes the function flow into component functions (S13), and searches the component DB for a software component capable of executing each component function.

(S14). For example, in the example shown in FIG. 8, the software search unit 103 searches the component DB for the software component for which the delivery date is to be searched and the software component for which the price is to be searched.

 At this time, the software search unit 103 uses the capability / operation check unit 105 to confirm that each searched software component can perform a service. There are two types of confirmation, one is to confirm the capability of each software component based on the metadata provided at the time of registration, and the other is to confirm that the service is actually available now. The software components that have been confirmed to be capable and usable are extracted as software component candidates.

Next, the function flow is executed for each component function (S15). The execution of the component function of the process S15 will be described in detail later with reference to a flowchart of FIG. The software execution unit 110 executes the component function (S15), and when the execution of all component functions constituting the function flow is completed (S16, Yes), the evaluation result of the executed function flow is obtained. Is output to the result management unit 108. The performance management unit 108 records the evaluation result in the functional flow performance DB (S17). Then, when the execution of the function flow is successful (S18, Yes), the execution result of the integrated function is generated based on the execution results of all the component functions constituting the integrated function, and this flow ends. On the other hand, if the execution of the function flow fails (S18, No), the process returns to step S12, and if there is an unexecuted function flow among the function flow candidates, the function flow with the next priority is executed. As described above, the execution of the function flow is performed in order from the highest priority until the execution is successful. Next, the operation of executing the component functions of the processing S7 and the processing S15 will be described in detail. FIG. 11 is a flowchart showing an example of a function execution operation. First, the software search unit 103 outputs, to the software determination unit 102, a search for software-to-air components that can perform the component function obtained by the search. The software deciding unit 102 sends the request parameter and the catch of the software component to the rule engine unit 106.

 Next, the rule engine unit 106 performs pre-processing of the performance calculation. Here, information on software parts that do not work well with a specific input, and rules for applying specific software customers when they prefer to use their own software parts are given as rules. Applying rules to remove software component candidates in advance and replace software components. The rule engine unit 106 outputs to the priority order determining unit 107 the required parameters and the pre-processed software component findings.

 The priority order determining unit 107 calculates which software component is optimal using the past results, and determines the execution priority of the software component candidate (S21). Here, an example of the operation of determining the execution priority of the software component will be described. First, the performance calculation unit 107 extracts the score of the given software component from the performance management unit 108. Based on this score, the priority of the software component is calculated, and priorities are assigned in accordance with the priority. Software components up to the specified order are considered as software component candidates, and the software component candidate and the priority are determined by the software decision unit 1. 0 Output to 2. Execution of software components is performed in order from the highest priority.

 Next, the software deciding unit 102 passes the required parameter, the software component candidate, and the priority to the software execution unit 110. If there is no unexecuted software component (S22, No), this flow ends. On the other hand, if there is an unexecuted software component among the passed software components (S22, Yes), the process shifts to processing S23. Here, this is included when there is no corresponding software component in the process of S3 and when there is no unexecuted function flow.

Next, the software execution unit 110 executes the software including the software component to be executed. The software providing server is accessed to acquire the software component, and the software component is executed (S23). Each of the software providing servers 2A, 2B, and 2C includes a software component storage unit that stores software components. The software execution unit 110 outputs the evaluation result of the executed software component to the performance management unit 108. The performance management unit 108 records the evaluation result in the component performance DB (S224). Then, when the execution of the software component is successful (S25, Yes), the execution result of the software component is generated as the execution result of the component function, and this flow ends. On the other hand, if the execution of the software component fails (S25, No), the process returns to step S22, and if there is an unexecuted software component among the software component candidates, the priority order of the software component is the next. Perform the execution of As described above, the execution of software components is performed in order from the highest priority until execution is successful.

 The integrated service providing server 1 according to the present embodiment prepares a candidate for a functional flow or a candidate for a software component that operates on the same input. If it does not happen, it can work. Then, the software component providing servers 2A, 2B, and 2C can delegate to other software components without forcing the input range to which they are weak.

 As described above, by accumulating the evaluation results of the function flows executed in the past and the evaluation results of the software components executed in the past, and accumulating the results, the optimal performance of the results as the use of integrated services progresses. The dagger goes on. By utilizing this track record, it is possible to select an appropriate function flow or software component according to the request.

Next, the simulation unit 111 will be described. When a new software component is introduced, there is a problem that it is not selected because there is no track record for the software component, and no results are accumulated because it is not selected. In addition, even if the results are not obtained even at the time of initial operation, there is a risk that operation may become unstable. Therefore, the integrated service management server 1 according to the present embodiment includes the simulation unit 111. Simulation unit 1 1 1 is actually an integrated service for users Rather than providing services, .Acquire achievements by performing tests similar to actual services. The simulation unit 111 provides software components that provide the software components at the timing required by the administrator of the integrated service management server 1, when new software components are applied, and during times of low service demand. It automatically accesses the server and executes software components for testing to acquire results. The operation in this case is not subject to billing! / ,.

 As described above, the integrated service management server 1 according to the present embodiment can newly accept new software components even during operation, and can improve the quality and stability of operation. In addition, it is possible to confirm beforehand whether there is any problem in the operation.

 In the present embodiment, the software execution unit 110 executes the functional flow or the execution of the software component in order from the highest priority to the success, but sufficient resources for the same request. Yes, if there are many candidates, the software execution unit 110 may execute multiple function flows or software components at the same time without failure and return a better execution result. Good. In that case, even if it fails, faster operation can be obtained compared to selecting another candidate after failure, and achievement is accumulated for other candidates because multiple operations are performed There are advantages. In particular, when registering a new software component, for example, processing is performed to mix the new software component into the function flow at a specified ratio, and it is possible to accumulate the results of the new software component.

 In addition, when the execution result of each function flow or software component is different, a process for increasing the accuracy may be performed on the obtained execution result or the actual high-level function flow or execution result of the software component. . In this case, the software execution unit 110 can select a highly accurate result and return it to the client 3. In addition, when there are requests from the three clients to return multiple results, it is also possible to rank all the execution results obtained with this accuracy and return them.

Next, the charging operation in the integrated service providing system will be described. The flow of money associated with an integrated service providing system can be broadly divided into two types: the amount paid by the integrated service user and the amount received by the provider of each software component. The difference is the amount that the integrated service provider receives. Here, it is assumed that the cost for the integrated service is paid from the amount received by the provider of the integrated service. The charging calculation as described above is performed by the charging calculation unit 112.

 First, the amount paid by the user of the integrated service will be described. For the user of the integrated service, calculate the sum of the standard charges determined by the combination of software components and the cost of providing the integrated service, and set a higher price. In some cases, this amount is determined by comparing other equivalent services, etc. In such a case, the standard charge for each software component is adjusted based on the service price. Next, the amount received by the provider of each software component will be described. Regarding the amount of money received by each software component provider, the charging method here is a combination of base charging, incentive charging, and penalty charging.

 The base charge is an amount that indicates how much payment is guaranteed each time a software component is used. Base pricing depends on the strategy and takes into account the prevailing prices in the market.

 A penalty charge is an amount calculated based on the loss of a case that was not available when needed. Here, the inability to access at the required timing is mechanically counted, and a penalty is applied to cases where no actual harm was caused due to the fact that it could be supplemented by substitute parts. The penalty amount is based on an amount that the provider of the integrated service can use to make the software component provider aware that the service will be degraded due to the reduced availability. A penalty amount shall be imposed based on this.

The incentive fee is a fee that is determined by the substitutability and performance of the software component. Here, the incentive billing will be described in detail. The degree of contribution for each software component required for incentive billing is calculated by correlation analysis between the performance of the provided service and a set of similar performance. First, the results that have the required parameters similar to the provided service results are extracted. Next, a correlation analysis is performed using the score of each software component included in the extracted performance and the score of the function flow included in the performance of the provided service, and the contribution of each software component is calculated. Put out.

 When multiple functional contacts are processed in parallel, all of the functional contacts that are actually executed are the targets of the contribution calculation. As a result, the replaceable software component is calculated to have a relatively low contribution, because the case where the component is applied by replacing another component is also calculated. The contribution of software components is calculated high. The total amount provided for the incentives distributed according to the contribution of each software component in the provided service is equal to the amount of each software. Payment amount = base charge X number of uses + incentive charge-penalty charge ". Of these, incentive billing can make use of its track record and reflect market principles. Note that the integrated service providing system according to the present embodiment can also provide other feedback such as a point system in addition to charging.

 In the present embodiment, the integrated service providing server 1 is a system that selects and combines software components in response to a request from a user using the client 3 and provides the software component. However, the software component providing server 2A, A knowledge base with knowledge in place of 2B and 2C may be provided, and knowledge may be provided on demand. This knowledge base is provided with information of a certain knowledge provider. The request from the user in this case is knowledge in a particular situation. The user feeds back to the integrated service providing server whether or not the knowledge was suitable for the request, and the integrated service providing server obtains the feedback as an evaluation result and accumulates it as a result, thereby acquiring the knowledge according to the request. Properly select and provide. Furthermore, instead of billing, a provider of knowledge can receive a point based on the evaluation result of knowledge. For example, when an integrated service providing system is used in a company, this point can be used as a reward, etc., thereby promoting incentives and inputting high-quality knowledge. . Embodiment 2

In the present embodiment, the integrated service providing server 1 executes software. First, an example will be described in which the software component providing servers 2A, 2B, and 2C execute the software component. Here, the execution and evaluation operations will be described. Except for the operation described below, the same operation as in the first embodiment is performed.

 In this embodiment, the software component providing server 2A, 2B, and 2C execute software components on the software component providing server. Therefore, in addition to the software component storing unit, the software component providing server includes a calculating unit and an error processing unit. And an evaluation processing unit.

 First, the software execution unit 110 transmits a software component execution instruction and an argument to the corresponding software component providing server in the execution of the software in the process S23. The software component providing server that receives the execution instruction and the argument from the software execution unit 110 executes the software component in the calculation unit. The error processing unit processes an error caused by execution of the software component. The evaluation processing unit evaluates the execution of the software component. The evaluation results generated by the evaluation processing unit include the success or failure of execution success or failure, whether the input is optimal for the software component, the error that occurred in the software component during execution, the performance such as speed, etc. is there. After executing the software component, the software component providing server transmits the execution result and the evaluation result to the integrated service providing server 1.

 On the other hand, the software execution unit 110 also evaluates the execution of the software component providing server. The evaluation result generated by the software execution unit 110 in this case is, for example, whether or not the ability to access the software component providing server at the time of execution instruction is given. The software execution unit 110 that has received the execution result and the evaluation result from the software component providing server outputs the evaluation result from the software component providing server and the evaluation result generated by itself to the result management unit 108. The performance management unit 108 records the evaluation result in the functional performance record DB or the software component performance DB. Embodiment 3.

In the present embodiment, an example is described in which the integrated service providing server 1 and the software component providing servers 2A, 2B, and 2C do not execute software, and pass the function flow or software components to the client 3 as they are. I do. Here, the operation of execution will be described. Except for the operation described below, it is the same as the first embodiment. Perform the same operation.

 In the present embodiment, when a user sends a request message using the client 3, the request message can be changed so that the function flow or the software component is returned as it is. The software execution unit 110 transmits, via the client interface unit 101, the client 3 having the higher priority among the functional flows or software components selected in response to the request. The client 3 executes the software component and transmits the evaluation result on the quality of the software component to the integrated service providing server 1.

 The result acquisition unit 109 acquires the evaluation result from the client 3 via the client interface unit 101 and outputs the result to the result management unit 108. The performance management unit 108 records the evaluation result in the functional performance result DB or the component performance DB.

 In addition, the integrated service providing server 1 may return the plurality of function group candidates and the software components i to the client 3. In such a case, the client 3 can select the function flow or software component.

 Also, the integrated service providing server 1 does not send the software component to the client 3 but sends information such as the selected function component, the provider of the selected software component, the provider network ID, and the component ID. Alternatively, the client 3 may acquire and execute a software component from the software component providing server. Possibility of industrial use

As described above, according to the present invention, it is possible to realize high quality and stability in the operation when software components are integrated by selecting and combining software components using the results. Is possible. Also, by registering a plurality of corresponding software components for one request, it becomes possible to integrate and cooperate with scattered software components. The man-hours required at that time are dramatically reduced by using the actual results, and the stability of operation is ensured. In addition, billing for services is not performed by the individual software component provider, but based on the degree of contribution, so highly practical billing can be realized, and new software It will also facilitate the registration of air components.

 Also, for users, the difficulty and complexity of finding and combining target services is greatly reduced. In addition, providers of software components involved in integration will be able to reduce the barriers to providing services by acting on behalf of combining services with other services to make the services used.
