Description

  The present invention relates to a requested service proposing apparatus, system, method, and program suitable for use in proposing a service according to a user request by voice.

  Currently, a project is underway to replace the existing telephone network with the next generation network NGN (Next Generation Network). In NGN, the telephone network has been changed to IP (Internet Protocol), which facilitates cooperation between Web services and telecom networks, and is expected to create new services. A Web service is a service component that is handled as a component for performing a service on the Web. The telecom network is a public line network that can connect various communication networks such as a telephone / data communication network.

  A service composition engine has been studied as a Web service cooperation platform (see Patent Document 1). Patent Document 1 discloses a technology for making a service proposal according to a user's preference and situation by discovering and executing a service element that is a component of various components based on a service template describing a service execution scenario. ing.

  In order to describe a service template in the service composition engine, a scenario that links a plurality of Web services is created. Conventionally, a scenario is manually created by a user, so it takes time, and it is difficult to perform detailed customization according to the user.

As described above, since the work process is complicated and takes a long time to create a new service scenario, the efficiency is low when a user-specific service with a low service usage frequency is performed. In the service generation system described in Patent Document 1, the service template is described in an abstract manner, or the service template is generated based on the service usage history by the user, whereby the service template is described. I was trying to save time.

That is, the request analysis device 21 performs analysis processing on each item constituting the request term requested by voice input. For example, the request analysis device 21 analyzes each item constituting the request term corresponding to a predetermined keyword. Is output.

  The request proposal generating device 22 receives the analyzed data, and performs a service proposal for the request item 3 by performing processing according to the data content. For example, if the request analysis device 21 is a media server (multimedia archive server), the request is keywordized by performing voice analysis based on the input voice information. For example, if the request proposal generating device 22 is a service composition system, the service composition system provides a service to the user by processing based on the keyword analyzed by the request analysis device 21 (media server).

  FIG. 3 is a block diagram showing a configuration of the request proposal generating device 22 of FIG. Referring to FIG. 3, the request proposal generation device 22 includes a request component cooperation device 221, a request component cooperation scenario 222, and request components 223, 223,. Based on the data analyzed by the request analysis device 21, the request proposal cooperation device 221 searches for an existing scenario from the request component cooperation scenario 222 for service proposal. The request component cooperation scenario 222 is configured as a set of scenarios in which information in a predetermined format for executing a plurality of request components 223 in cooperation is described, and the request components 223 are called and executed in a certain order. ing. Further, the request proposal cooperation device 221 creates a new scenario or edits a scenario when the requested scenario does not exist in the existing request component cooperation scenario 222. Thereafter, the requested parts 223 described in the selected scenario are sequentially called, and a service is proposed to the request item 3 from the execution result.

  For example, if the request proposal cooperation device 221 is a scenario server, the request component cooperation scenario 222 is a scenario database, and the request component 223 is a Web service component, the request proposal cooperation device 221 (scenario server) requests the requested component based on the input keyword.

Based on the retrieved requested component linkage scenario 222, the scenario execution device 2213 calls the requested component 223 described in the requested component linkage scenario 222, and proposes a service to the request item 3 from the service execution result.

  For example, the keyword processing device 2211 may search from the input keyword as it is, or may search from the category information to which the requested component included in the requested component cooperation scenario 222 belongs.

  As described above, according to the present embodiment, the request item 3 based on the voice information input by the user is analyzed using a keyword or the like, and a service scenario corresponding to the request component cooperation scenario 222 using the analysis result is found. Since it is searched whether or not it exists, it is possible to reduce the overall processing time for executing the service scenario. Also, since the service is provided by voice input such as a telephone, the degree of freedom is high, and for example, the service can be provided without adding any function to the existing telephone. Therefore, the compatibility with existing systems is high and the threshold for introduction is low. In addition, it is easy to add functions, the user can freely customize the service, and the flexibility is high.

  Next, a more specific configuration example of the above-described embodiment will be described with reference to FIGS. 5 and 6. FIG. 5 is a system diagram showing a configuration example of a request service proposal system using a telecom network. FIG. 6 is a flowchart showing the flow of processing in the configuration shown in FIG.

  In FIG. 5, the NGN 61 is provided with a media server 63 that performs voice recognition and analysis. In the Internet 62, service elements (referred to as SE) 67, 67,. In a region where the NGN 61 and the Internet 62 overlap, a composition engine 64, a scenario database 65, and a web service search database 66 are provided.

  In the configuration shown in FIG. 5, the media server 63 recognizes voice information that is input verbally by the user 68 by operating a voice communication terminal 69 such as a subscriber phone or a mobile phone, and performs morphological analysis, voice analysis, keywordization, etc. The processing result is transmitted to the synthesis engine 64. The media server 63 corresponds to the request analysis device 21 in FIG.

  The scenario database 65 is a database that records and manages a plurality of service templates (referred to as ST) describing service execution scenarios. The scenario database 65 corresponds to the required component cooperation scenario 222 of FIG. The Web service search database 66 is a search system for Web services such as UDDI (Universal Description, Discovery and Integration), and provides a function for a user to search for a Web service that matches a purpose.

  The synthesis engine 64 searches for the ST recorded in the scenario database 65 or creates the ST, and then uses the Web service search database 66 based on the ST corresponding to the user's request. By discovering and executing SE67, 67,..., A service proposal is made according to the user's preference and situation. A combination of the composition engine 64, the scenario database 65, the Web service search database 66, and the SEs 67, 67,... Corresponds to the request proposal generating device 22 in FIG.

  Next, a Web service (WS) cooperation proposing method using telephone voice as an input will be described with reference to FIG. The user 68 can receive information-based services (for example, register in advance) by verbally requesting information using the telephone 69 (for example, by saying “Please mail me a shop that can be used for meetings in Shinjuku”). The e-mail 70 describing the contents of the reply is sent to the e-mail address that has been sent). At that time, the NGN 61 analyzes the voice, selects and creates an ST by the synthesis engine 64 based on the keyword, and executes the service after searching SE67. The processes in this service are enumerated in chronological order as follows.

  When the user transmits a request by voice input, the media server 63 recognizes voice data (step S1). The media server 63 converts the analyzed voice into a keyword (step S2). The composition engine 64 searches for an existing ST in the scenario database 65 based on the keyword (step S3). If the ST does not exist, the composition engine 64 edits / creates the ST (step S4). Next, the composition engine 64 searches each SE for executing ST (step S5). Next, the composition engine 64 executes SE67 based on the selected / created ST (step S6).

  In the above processing, speech analysis can be realized with high accuracy by using off-the-shelf software, which can be converted into natural language text equivalent to daily conversation. In addition, there are abundant tools for keyword extraction, which can be extracted with high accuracy.

  In addition, as a method for searching and selecting STs based on keywords, for example, a method of searching existing STs based on a plurality of keywords and selecting existing STs, or deriving keyword categories and proposing similar STs is proposed. (That is, a method of searching for a similar ST from the category information of the latter keyword).

  According to the present embodiment, the following effects can be considered for an existing system. In an information providing service using an existing telephone, a service is often selected using numbers as input. In this method, the number of services to be provided is limited, so that the service is provided with a low degree of freedom. In addition, since existing weather information and route search services based on voice recognition can only provide a service with a fixed procedure, it is impossible to customize a user to freely link WS and lack flexibility. On the other hand, according to the present embodiment, it is possible to increase the degree of freedom (flexibility, customizability) by making the input voice input, it is easy to add functions, and the user can freely combine services. The effect of being able to be able to be obtained.

  The embodiment of the present invention is not limited to the above-described configuration, and the constituent elements shown divided into blocks may be further divided and distributed via a communication line, or may be integrated. It is possible to appropriately change the number of blocks into a small number of blocks. Each configuration can be configured from a computer and its peripheral devices, and a software program for controlling the computer and peripheral devices. The program in this case can be distributed via a computer-readable recording medium or a communication line.
