Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a conceptual diagram of a content information distribution network according to an embodiment of the present invention. FIG. 2 is an explanatory diagram of the positioning of the content information distribution network, and FIG. 3 is a diagram showing a business model of a request-call society led by a content provider.

By using the content information distribution network 23 shown in FIG. 2, the content provider 10 can directly propose the optimum content to the consumer 11 without relying on a third party service provider. Can be. That is, a multicast-type matching mode can be realized in comparison with the conventional broadcast-type matching. This is an imaginary network for the purpose of collating content information in order to build a listening society on the network 21, and is positioned as an upper layer of the content distribution network 22.

<Concept of Autonomous Distributed Matching Environment> An autonomous distributed matching environment, which is an architecture for realizing a content information distribution network, will be described with reference to FIG. Further, as an example of using the autonomous distributed matching environment, an application (UA, CA) operating on the autonomous distributed matching environment will be described.

(1) User Agent (UA) The user agent UA is an agent of the end user, and registers user preference information based on the end user's preference in the event place. This is called a filter.

(2) Content Agent (CA) The content provider 10
The content keyword (content information) and the content identifier are registered with the content agent CA, which is the agent 0. The content identifier is an identifier for uniquely identifying content in a distributed processing environment. For example, in the case of a Web server,
If L is a distributed object (CORBA object), Object Reference + file name is used as the content identifier. The content agent CA sends these as events to the event place 30 and gives the event place 30 a stimulus (Incentive). here,
The content agent CA is mainly divided into two usage patterns. One is a content agent used from the perspective of a service provider (content information provider), and the other is as a content provider. The latter is used as a means for the content provider 10 itself to easily become a content information provider.

(3) Event Place The event place 30 provides a place for collating (filtering) an event sent by the content agent CA with a filter registered by the user agent UA. As a result of the matching, the filter through which the event has passed is ignited, thereby providing an autonomous distributed matching environment in which the corresponding user agent UA is started autonomously. As a result, it is possible to realize the order-based collation led by the content agent CA. Each of the activated user agents UA can independently access desired content by using the content identifier acquired as an event.

The content agent CA registers the content keyword as a filter, while the user agent UA sends user preference information as an event. It can be easily realized using a distributed matching environment. FIG. 4 shows a business model of the autonomous distributed matching environment. The autonomous distributed matching environment is basically operated by a content information provider or a content provider.

<Processing mechanism and interface specification>
FIG. 5 is a configuration diagram of the autonomous distributed matching environment (ADCE). 6 and 7 are flowcharts showing the processing mechanism of the autonomous distributed matching environment. The processing mechanism and control interface of the autonomous distributed matching environment will be described with reference to these drawings.

First, in the flowchart of FIG. 6, (1) Activation and initialization of event place factory (step S1) Operator of autonomous distributed collation environment (hereinafter, ADCE operator)
Starts the event place factory on any machine as a server. The ADCE operator mainly corresponds to a content provider or a service provider (a content information provider such as Yahoo). At the time of initialization of the event place factory, a host name capable of generating an event place and a storage location of an execution file of the event place are given to the event place factory. These are called event place generation information.

(2) Event Place Generation Request (Step S2) A person who creates an event place (hereinafter, an event place operator) requests an event place factory to generate an event place. At this time, the event place name and the event place attribute are given as parameters at the time of the event place generation request. Here, the event place attribute indicates whether the generated event place is used for a listening or inquiry type. That is, it indicates the direction of the event.

(3) Generation of Event Place (Step S3) Upon receiving the event place generation request, the event place factory generates an event place. Specifically, at this time, an event place management object that manages the event place is generated. That is, the processing request to the event place is synonymous with the processing request to the event place management object. The event place factory returns the identifier of the generated event place (that is, the event place management object) to the generation request source.

(4) Event Place Initialization Request (Step S4) An event place initialization request is made. At this time, a single event place object or a multiple event place object is specified as a parameter. Further, a host capable of generating an event place object and the like and a storage destination of an execution file such as the event place object are provided. This is called event place object generation information.
If this is omitted, event place generation information is used.

The event place management object creates an event place object, an event type factory, and a filter factory. The multiple event place object is used for the purpose of improving the scalability by distributing the load of the event matching processing in the event place. In addition,
Within the event place, a centralized namespace is guaranteed by the event place management object.

(5) Session establishment request for event transmission to event place (step S5) The event place is requested to establish a session. The event place management object creates a proxy object for each session request. The session ID (that is, the ID of the proxy object) is returned to the request source. The event place management object indicates to the proxy object which event place object and event type factory to use when generating the proxy object. When a session establishment request for an event place is made, it is necessary to specify, as a parameter, whether the session is for transmitting an event or receiving an event. In this example, a session for event transmission is specified.

(6) Registration of Event Type (Step S)
6) Register the event type in the proxy object. At this time, the proxy object requests the event type factory to generate an event type object. Further, the event type is stored in the generated event type object.

On the other hand, it is possible to request the event place to register an event type. At this time, the event place management object requests the event type factory to generate an event type object, and stores the event type in the generated event type object. Note that registering an event type with the same name will result in an error.

(7) Request for Establishing a Session for Receiving an Event to Event Place (Step S7) The event place is requested to establish a session for receiving an event. At this time, the requester of the session establishment gives, as parameters, the identifier of the event reception object which is the notification destination of the event, the event reception, and the event notification method (firing type, look-in type). The event place management object creates a proxy object for each session request. The session ID (that is, the ID of the proxy object) is returned to the request source. The event place management object is a proxy
When creating an object, tell the proxy object which event place object and filter factory to use.

(8) Filter generation request (step S
8) Ask the proxy object to generate a filter. At this time, the proxy object requests the filter factory to generate a filter object.
The generated filter identifier (ID) is returned to the event reception / object. The proxy object manages the correspondence between the filter object and the filter identifier.

(9) Setting of Filter Value (Step S9) The filter (proxy object) is requested to set a filter value using the filter ID as a parameter. At this time, the event type object is requested to check whether the data structure of the filter is correct, using the event type name stored in the filter (that is, the event type name to be filtered) as a key. If not, an error occurs. However,
If a wildcard is specified, this check is not performed.

(10) Filter Registration (Step S10) Using the filter ID as a parameter, a request is made to the proxy object to register the filter. On this occasion,
Event reception becomes possible.

Next, in the flowchart of FIG. 7, (11) Event transmission (step S11) An event is transmitted to the proxy object. At this time, the proxy object requests the event type object to check whether the data structure of the event is correct, using the event type name stored in the event as a key. If it is correct, the process proceeds to step S12; otherwise, an error occurs.

(12) Event collation request (step S
12) The proxy object forwards the event to the event place object. At this time, the event place object generates a thread. Note that a thread is generated for each event, and each thread performs multiplex processing of the event.

(13) Collation with Filter (Step S1)
3) The thread performs a filtering process by matching the event with the filter object. This includes perfect match, partial match, weighted match, etc., which can be specified when setting the filter value.

(14) Activation of Proxy Object (Step S14) As a result, when an event passes the filter, the corresponding proxy object is activated and receives the event.

(15) Activation of Event Reception Object (Step S15) The proxy object further activates the event reception object and passes the event to the event reception object. This corresponds to the firing type (interrupt type) event notification. Note that, instead of the proxy object activating the event receiving object, the event receiving object itself can also take out the event spooled in the proxy object corresponding to the event receiving object. This corresponds to a look-in type event notification. There are various triggers for the event reception / object depending on the service form, but as a typical example,
It is conceivable that the end user makes a content proposal request to the event reception / object.

<Federation Between Event Places> A federation agent (FA) is an agent that establishes federation between event places (see FIG. 8). For example, consider the case where event place A establishes federation with event place B. First, the federation agent FA belonging to the event place A registers a filter for the event place B. At this time, the content agent C belonging to the event place B
When A sends an event and, as a result, the filter fires, the federation agent FA starts autonomously. That is, the federation agent FA can be regarded as one user agent UA belonging to the event place B. Next, the federation agent FA resends the acquired event to the event place A to which it belongs. That is, the federation agent FA
Can be regarded as one content agent CA belonging to event place A. As described above, the federation between the event places can be easily realized by using the federation agent FA having both roles of the user agent UA and the content agent CA. That is, federation between event places can be realized with the same control logic as that for a single event place.

<Example of Event and Filter Value> An example of use of a filter and an event set in the autonomous distributed matching environment will be described. (1) User preference attribute and content condition Content information is represented by content condition, and user preference information is represented by user preference attribute. The content condition is a user agent U suitable for providing the content.
The condition of A is defined, and can be described as an example in FIG. On the other hand, the user preference attribute defines the characteristics of the end user (user agent UA), and can be described as an example in FIG. Conventionally, it has been common to use content attributes as content information and user preference conditions (search conditions) as user preference information. However, in the case of the order-taking type in which the content provider only provides the content to the user agent UA that is truly suitable, the condition of the user agent UA worthy of the provision is described in the content information, and the user agent is described in the user preference information. The above expression is newly defined because the form in which the attribute of the UA is described has a higher affinity with the order-based collation than the conventional form.

(2) Definition of Event and Filter The content agent CA sends out a content condition as an event. The procedure for creating this event is shown below. First, as shown in FIG. 11, an event type, which is an event template, is defined. Here, the event type name is a name for uniquely identifying the event type. In addition, a condition name, a data type and a conditional expression for the condition name are defined. Register the event type in the event place. An event is created according to the data structure of the event type (see FIG. 12). The event is
It consists of a combination of event type name, condition name and condition value. In the data part, a content identifier is set. Send an event to the event place. If the condition name or condition expression defined in the event does not match the event type, a transmission error occurs. However, the condition names used in the event may be a subset of the event type.

On the other hand, the user agent UA registers the user preference attribute as a filter in the event place. The procedure for creating this filter is described below. As shown in FIG. 13, a filter is defined. The filter consists of a pair of an event type name and an attribute name and an attribute value to be accepted. Only events belonging to the event type defined by the event type name to be accepted are subject to filtering. Here, a plurality of event type names can be defined, and by specifying a wild card (*. *), It is possible to target all events. Register a filter in the event place. If the attribute name defined by the filter does not exist in the condition name of the event type defined by the accepted event type name, a registration error occurs. However, a subset of the event type may be used.

The above-described embodiment has the following effects. First, an autonomous distributed matching environment proposed by the present invention can be easily constructed on a CORBA distributed environment. Second, by using the agent group in consideration of the user preference attribute and the content condition, the service application can
You can easily send out events or pick up necessary events. In this embodiment, a global content information distribution network can be easily constructed by using the event place provided by the autonomous distributed matching environment. Further, the present invention can be commonly applied to exchange of other information such as service information and communication information.
The present invention is also configured such that a storage medium storing a software program for realizing the functions of the above-described embodiments is supplied to a system, and a computer of the system reads and executes the program stored in the storage medium. It is possible. As the storage medium in this case, for example, a CD-ROM, a CD-R, a floppy (registered trademark) disk, or the like can be used.

[0060]

As described in detail above, according to the present invention,
The following effects are obtained. (1) It is possible for a content provider to easily realize a soliciting society in which content is provided to consumers who are suitable for the content. Conventionally, a form in which a consumer specifies content suitable for itself by inquiring type collation of a service provider led by a consumer has been common. As described above, the conventional inquiry-type collation can be easily realized using the autonomous distributed collation environment.

(2) The content provider can specify a consumer suitable for its own content without knowing the existence of the consumer. That is, the content agent means to the user agent means are transparent. Even when the inquiry-type matching is realized in the autonomous distributed matching environment, the user agent means does not know the existence of the content agent means (content information provider and content provider), and does not know the existence of the content agent means. Can be specified.

(3) The content provider itself can be the sender of the content information without relying on a specific content information provider. As a result, not only the content but also the content information can be transmitted by the content provider according to its own policy. This is effective not only for patron type collation but also for inquiry type collation. this is,
In the inquiry type matching, the inquiry request from the user agent means is sent to the event place as an event, and this event is achieved by being reflected to all the content agent means including the content provider.

(4) By federation between event places via the federation means, content information (events) distributed only in other event places can be taken into its own event place. That is, a content provider belonging to another event place can be used. Conversely, it is also possible to acquire a consumer belonging to another event place by sending an event to another event place. Thus, content information, consumers, and the like can be shared between different event places.

(5) Whether or not to allow the event place federation is basically an operational matter left to the event place operator, and is technically a global content information distribution using a federation mechanism. Can build a net. This is very similar to how the Internet was built by connecting LANs to each other (the Internet today would not have existed at the time the connection for a particular LAN was refused. , Federation agent means FA
Interconnection of event places via, as an operational issue, should basically be allowed). It is considered that a mechanism for guaranteeing the rights of the content provider and the event place operator is required. However, it is considered that this can be achieved in combination with the filter setting content and the click guarantee technology. On the other hand, protecting the privacy of end users is also an important issue. In the case of order matching, it is content information that circulates between event places as events, and the user preference information is concealed within the event place, so that the privacy of the end user can be protected relatively safely.

(6) User for Event Place
The load distribution of the agent means can be achieved, and a collation environment with high scalability can be constructed. (7) A content information distribution network can be constructed from the bottom up, and a global content information distribution network can be constructed.
