Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to semantic information for specifying content that meets the interests of end users from content distributed on a network, or for specifying the optimal consumer to which a content provider should distribute content. The present invention relates to a mailing list management method and management system using a network.

[0002]

2. Description of the Related Art FIG. 26 shows the structure of a mailing list service realized by a conventional mailing list management method. The mailing list is a mechanism for delivering the same mail to a plurality of specific persons by using an electronic mail delivered via a communication network such as the Internet. By using this mailing list service, it is possible to exchange mail between multiple users participating in the mailing list, decide on a specific theme, and get interested in it and exchange information and opinions Create a place where you can do it.

[0003] Also, the term mailing list includes:
There are two meanings: a case where a mechanism for exchanging e-mails between a plurality of users is shown, and a case where the list itself in which participating users are registered is shown.

In this conventional mailing list operation system, terminals 101 to 101 of mailing list users 1 to 4 are used.
104, Intermediary server 200 is Internet 500
And so on via a communication network such as.

[0005] This conventional mailing list management method will be described with reference to FIG. The numbers in parentheses in FIG.
The information to be transmitted is given in the order of occurrence.

(1) First, the users 1 to 4 wishing to participate in the mailing list connect via the Internet 500 to the intermediary server 200 that manages the mailing list, and register for participation in the mailing list.

[0007] The intermediary receives the participation registration of the users 1 to 4 who desire to use the mailing list service, and creates a mailing list in which the users who have accepted the participation registration are registered. The intermediary accepts participation and withdrawal from the mailing list at any time.

(2) When the user 1 whose mailing list has been registered wishes to send an e-mail to a user registered in the mailing list, the user 1
A desired mail is transmitted to the server 200 via “01”.

(3) The intermediary application managed by the intermediary receives the mail from the user 1 and transfers the mail to all the users registered in the mailing list. At this time, the intermediary may transfer the mail after providing an advertisement to the mail.

As a method of sending the same mail to a plurality of people at once, a method using a broadcast mail function of an electronic mail can be considered. With this broadcast mail function, each user prepares a broadcast list in which the mail addresses of other users who want to send mail are registered, and sends mail using this broadcast list. This is a function that can send e-mail to multiple users at once.

[0011] The broadcast mail function can also be used to exchange mail between a plurality of users. However, when this broadcast mail function is used, all users always have the same broadcast contents. You need to have a list ready. Therefore, when a user is added or changed, each user must change the content of the broadcast list. If the number of people is small, it can be handled sufficiently, but if the number of people is tens, the replacement is often frequent, and rewriting the broadcast list every time will be a great effort. For this reason, troubles such as a failure to send an e-mail to a certain person are likely to occur, and in the case of an important circulation e-mail, it may be a cause of inconsistency in communication later.

[0012] Therefore, in the case of exchanging e-mails between groups in which any person freely participates and withdraws, this broadcast e-mail function cannot cope.

[0013]

The above-mentioned conventional mailing list management system has the following problems since it is necessary for an intermediary to exchange mail between a plurality of users. . (1) When the scale of mailing list users increases, the intermediary must frequently update the mailing list due to the participation or withdrawal of the mailing list from a large number of users. It is difficult to respond to changes in the mailing list in real time. (2) An intermediary fee is generated, or an advertisement is attached to an e-mail by an intermediary. (3) With the increase in the number of mailing list users, the load on the server operated by the mediator is concentrated, the real-timeness of mail distribution is further reduced, and an expensive large-scale server is required. (4) Mailing list users know the existence of an intermediary,
It is necessary to connect to a download server or FTP server operated by an intermediary and register for participation. However, the number of contents distributed on the network is increasing with the spread of the Internet, and the mailing list service that is optimal for me Is difficult and time-consuming to find. (5) The confidential information relating to the privacy of the mailing list user is centrally managed by the mediator, and the risk is not distributed when the server used by the mediator is intruded. In addition, when the reliability of the confidential information management of the mediator is low, there is concern about disclosing the privacy information to the mediator itself.

(6) Users of the mailing list must follow the mailing list service management policy (policy) specified by the intermediary.

The present invention has been made in view of the above-mentioned problems of the conventional technology, and has been made by making it possible to operate a mailing list service using a network without going through an intermediary. A mailing list that solves problems, in particular, improves the real-timeness of mail distribution and participation in and withdrawal from mailing lists, enables users to operate according to their own policies, and improves the security of users' confidential information The purpose of the present invention is to realize an operation method and an operation system.

[0016]

In order to achieve the above object, a mailing list management method according to the present invention comprises a transmitting terminal for transmitting data as an event, and a terminal for selectively receiving the data transmitted as an event. , A mailing list operation using a semantic information network that sends and receives e-mails between multiple users using a semantic information network composed of a receiving terminal in which a filter consisting of an event type and an acquisition condition is set The method, wherein the transmitting terminal transmits an e-mail to be transmitted to another user to the semantic information network as the event together with information indicating a mailing list to be transmitted, and the information indicating the mailing list is set as a filter. The receiving terminal that is The a step of receiving from the semantic information network.

[0017] The transmitting terminal may be set so that a mail can be transmitted only to a mailing list in which the transmitting terminal is set by setting a filter.

According to the present invention, the mailing list service can be operated using a network without an intermediary, so that the real-time property of mail distribution, participation in the mailing list, and withdrawal from the mailing list is improved. It is possible to operate by policy, and it is possible to improve the security of confidential information of users.

[0019] Also, the chat service operation method of the present invention provides a transmitting terminal for transmitting data as an event, and a filter comprising an event type and an acquisition condition for selectively receiving the data transmitted as an event. A method of operating a chat service using a semantic information network, wherein sent / received text data is transmitted and received between a plurality of users by using a semantic information network configured with a receiving terminal that is set. Transmitting the sentence data to be transmitted to other users to the semantic information network as the event together with information indicating the chat service desired to participate, and a receiving terminal in which the information indicating the chat service is set as a filter. Transmits the sentence data transmitted as an event to the semantic information network. And a step of displaying received from the work.

According to the present invention, it is possible to operate a chat service using a network without an intermediary, thereby realizing the real-time transmission / reception of text data between users and the participation and withdrawal of a chat service. It will be improved and it will be possible to operate according to the user's own policy,
Security of the user's confidential information can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Before describing the present invention, a distributed network system which is a prerequisite of the present invention and has enhanced message characteristics of information to be transmitted will be described.

As a distributed type network system, a system using Napster is known, and as a network system with enhanced dispersibility, Gnut is used.
One using lla is known.

First, a network system using Napster will be described. The Napster user sends a search request to the Napster server that stores the information of the file published by each Napster user, and the Napster server sends information such as the IP address of the Napster user who owns the searched file. Reply. The actual exchange of files is performed by the user who has obtained the IP address directly accessing the Napster user who owns the target file without going through a Napster server.

In the case of a network system using Gnutella, the terminal of the Gnutella user is:
The state of the connected partner terminal is periodically checked, and messages and file search requests are relayed. The search results are returned to the person who made the search request, and the subsequent file transfer is performed directly between the users, similar to Napster. As a result, a network is constructed without using a server.

In each of these network systems,
The system using Napster does not achieve the object of the present invention because it requires a server corresponding to an intermediary which is a problem of the present invention.

In a network system using Gnutella, a message or file search request is made without using a server, but the information to be transmitted is simply a file search request, and a user who confirms this response transfers the file. Is performed between users, and is not suitable for a form that requires one-to-many exchange such as an auction or a reverse auction.

There is a semantic information network system described below as a distributed network system in which the message of transmitted information is enhanced, and the present invention is based on the use of such a semantic information network system.

First, a semantic information network (Semantic I
An outline of an nformation-Oriented Network (hereinafter, referred to as a SION) will be described. The SION is a network that can deliver an event to a destination based on semantic information. FIG. 1 shows a conceptual model of the SION. In FIG. 1, each terminal 2 has semantic information (Semantic
Information: SI) is registered for ION1.
On the other hand, the terminal 2 that transmits the event sends an event composed of semantic information (Semantic information) and data (Data) shown in FIG. Here,
The semantic information describes characteristics of data included in the event, and is positioned as meta information of the data. For example, the semantic information is as follows:-Deliver the data to "Tokyo residents". -Deliver the data to "People interested in classics". -Deliver the data to "people who have a communication environment of 1 Mbps or more".・ Deliver the data to "people who are traveling on Mejiro Street". Deliver the data to "content providers with content that matches the keyword (eg, travel)". Is used.

The SION dynamically determines an object (terminal, person, software, etc.) to which data is to be delivered based on the semantic information as described above, and delivers the data to the specified target person. It is an autonomous decentralized meta-network that can make notifications. By using this SION, it is possible to directly propose own information only to users who are appropriate for the information provider to provide without using a broker. In this case, a business model that enables peer-to-peer information proposals with a broker-independent type (non-broker model) is called a patronage model (or a patronage-type information proposal model or non-broker model). Call. Similarly, a real-time information search that allows a user to directly search for desired information without using a search service (broker) is also possible. In addition, it is possible to apply to the following services and the like as a request-by-order information proposal service. (1) Manufacturing company: I want to send product information mainly to customers who are likely to be interested in their products. (2) Advertiser: I want to send a personalized advertisement for each customer. (3) Barter: I want to buy and sell or exchange products based on agreement between users.

Note that what information is set in the data part of the event depends on the service. For example, various usage forms such as an entity of information, a reference to information (URL, distributed object identifier, etc.), a proxy (Jini proxy, etc.), and a mobile agent are possible.

Next, the details of the SION will be described.

<SION Architecture> First, SIO
N network architecture will be described. FIG. 3 shows a network model of the SION. Here, for convenience of explanation, the terminal 2 is replaced with the transmitting terminal 21 of the event sender.
And the receiving terminal 22 of the event receiver. The event receiver uses the reception terminal 22 to receive the semantic information (the type of the received event and the acquisition condition) of the event desired to be received by the SIO as metadata.
Register with N1. This is called a filter. On the other hand, the event sender uses the transmission terminal 21 to
By sending an event to 1, the SION is incentived. This event is composed of semantic information and data describing characteristics of the event, as shown in FIG. FIG. 4 shows the definition of the semantic information. The semantic information is event metadata and is an instance of a semantic information type (event type).

The SION 1 is an autonomous distributed collation network for collating (filtering) an event sent by an event sender with a filter registered by an event recipient. As a result of matching, the filter that passed the event (reacted to the event)
n) Then, the receiving terminal 22 of the corresponding event receiver autonomously starts. With this mechanism, it becomes possible to search and find the target terminal 2 in a scalable and real-time manner from an unspecified number of terminals 2.

Next, the event type will be described.
FIG. 5 shows an example of defining an event type that is a template of an event. As shown in FIG. 5, the event type includes an event type name (Event type name) and a condition name (in FIG. 5, “Service” and “CPU power” correspond to each other), and a data type for each condition name ( St
A conditional expression (corresponding to == or> =) is defined. The event type name is a name for uniquely identifying the event type.

The parent type of the event type can be inherited.

As shown in FIG. 6, an event is created according to the data structure of the event type. An event is composed of an event type name, a combination of condition name and condition value, and
It consists of a data section. If the condition name, condition expression, and condition value defined in the event do not match the event type, an error will occur. However, the condition names used in the event may be a subset of the event type.

FIG. 7 shows a definition example of the filter. The filter accepts the event type name (Event type nam
e), attribute name (in FIG. 7, "CPU power" or "Ag
e ") and an attribute value (equivalent to 200 and 25 in FIG. 7). Only events belonging to the event type defined by the event type name to be accepted are subjected to filtering. Can have multiple event type names defined,
By specifying a wild card (*. *), It is possible to target all events. If the attribute name defined by the filter does not exist in the condition name of the event type defined by the event type name to be accepted, an error occurs. However, a subset of the event type may be used.

Next, the configuration of the SION 1 will be described. FIG.
FIG. 3 is a diagram showing a configuration of a SION1. As shown in FIG. 8, SION1 is a semantic information switch (Semantic Informa).
Option-Switch, shown as SI-SW in the drawing, Semantic Information -Router, shown as SI-R in the drawing, Semantic Information Gateway (Semant
ic Information-Gateway, which is shown as SI-GW in the drawing).

The semantic information switch (SI-SW) collates the semantic information registered as a filter with the semantic information given to the event, and as a result, activates a switching mechanism for activating the terminal 2 of the event receiver that fired. provide. The semantic information switch (SI-SW) and each terminal 2 are connected in a star configuration.

The semantic information router (SI-R) selects an event path between the semantic information switches,
And transfers the event sent from the to the semantic information switch to another semantic information switch. This is achieved by dynamic event routing based on semantic information.

The semantic information gateway (SI-GW)
Transfer events between event places. Here, the event place is a minimum unit (ontology domain) that guarantees a common semantic information space. In the event place, the uniqueness of the ontology system such as the name, concept, vocabulary, meaning, and association of the event type is guaranteed, and the semantic information is described based on the common ontology. Basically, the event sent from the terminal 2 of the event sender is distributed only in the event place, but the semantic information gateway (SI-
Through the GW), it is possible to exchange events between event places having different ontology systems. At this time, the semantic information gateway (SI-G
W) performs the ontology conversion of the event, and then transfers the event to a different event place.

<Operation mechanism and interface specification>
As an example of a method of implementing the SION1, an implementation method using a distributed object technology will be described. Here, SI-SW, S
The IR and the SI-GW are implemented as distributed objects called an event place object (EPO), a shared link object (SLO), and a federation agent (FA), respectively. The operation mechanism and control interface of the ION 1 will be described in detail with reference to FIG. In addition, SION-MT (Managem)
ENT Tool) or the ION interface, the ION1 network interface can be used. Also, using MT, EPO
Withdrawal, increase / decrease, dynamic change of physical link information, PO migration (dynamic change of EPO to which PO is bound),
It is easy to collect the firing rate, collect statistical information on popular coastal information and popular information.

Startup and Initialization of Event Place Factory (FIG. 9 (1)) First, the SION operator starts an event place factory (EPF) on an arbitrary host, and then starts the EPF.
Is initialized. At this time, a host name capable of generating an event place (EP) and a storage location of an executable file of the EP are given to the EPF. These are called EP generation information.

A request to generate an event place (FIG. 9)
(2)) Next, the EP operator requests the EPF to generate an EP. At this time, an EP name and an EP attribute are given.
Here, the EP attribute indicates whether the generated EP is used for a purpose-built model or an inquiry model, and indicates the direction of the flow of the event.

Generation of Event Place (FIG. 9 (3)) Next, the EPF that has received the EP generation request generates an EP. Specifically, at this time, an event place management object (EPMO) for managing the EP is generated. That is, the processing request to the EP is EPMO
This is the same as the processing request to. The EPF returns the identifier of the generated EP (that is, EPMO) to the generation request source. The EPMO is generated for a dynamically determined host from among the hosts capable of generating an EP specified in (1) of FIG. As a method of determining the host to which EPMO is to be started, the destination to be started is determined cyclically.
It is possible to select a method such as deciding according to the traffic or explicitly specifying the boot destination host.

An event place initialization request (FIG. 9)
(4)) Next, the EP operator requests EPMO to initialize the EP. At this time, a single event place object or a multiple event place object is designated. When a multiple event place object is specified, it is necessary to provide physical link information (topology) of the event place object (EPO) together. Here, the physical link information of the EPO expresses which other EPO knows which other EPO exists.

For example, as shown in FIG.
32 is EPO1 • 31, EPO3 • 33, EPO4 •
Knows the existence of EPO3, but EPO33
・ It expresses that only 32 existences are known. As described above, the multiple EPO aims at improving the scalability by distributing the load of the event matching process in the EP.

The EPMO is used to select an EPO from the host list capable of generating an EP specified in (1) of FIG.
Is dynamically determined, and EPO is generated there. At this time, each EPO has one filter factory (FF) and one statistical information collection object (S
O) are always generated accompanying them, and these correspond to SI-SW. Further, a shared link object (SLO) is generated accompanying each EPO according to the number of physical links. For example, three S for EPO2 · 32
LO is generated (SLO2,1, SLO2,3, SLO in the figure)
These correspond to SI-R. E
The method of determining the activation destination of the PO is the same as that of the EPMO, but it is also possible to fix the EPO to be used for each event type. The EPMO generates an event type factory (ETF) in the EP. Within the EP, a unified event type namespace is guaranteed by the ETF.

Request for Session Establishment for Event Transmission to Event Place (FIG. 9 (5)) Next, a request is made to the EP to establish a session. EPMO
Is a proxy object (PO) for each session request
Generate The session identifier, which is the identifier of the PO, is returned to the request source.

It should be noted that the EPMO uses the PO
Is instructed which EPO to use (to bind with which EPO). This instruction is for multiple EPO
However, the method of determining the EPO to be bound is the same as that of the EPMO. When a session establishment request is made to the EP, it is necessary to specify whether the session is a session for event transmission or a session for event reception. In this example, a session for event transmission is specified.

Registration of Event Type (FIG. 9 (6)) Next, the PO is requested to register the event type. At this time, the PO requests the ETF to generate an event type object (ETO). Further, the event type is stored in the generated ETO. On the other hand, an event type registration can be requested from the EP. At this time,
EPMO requests the ETF to generate an ETO, and stores the event type in the generated ETO. Generally, an event sender registers an event type via a PO. On the other hand, the EP operator registers an event type in the EP. Note that registering an event type with the same name will result in an error.

Request for Establishing a Session for Receiving Events for Event Place (FIG. 9 (7)) Next, a request is made to the EP to establish a session for receiving events. At this time, the requester of the session establishment (event receiving object) sets the identifier of the event receiving object, which is the event notification destination, and the event notification method (firing type, look-in type) as parameters. Give as.

Subsequently, the EPMO generates a PO for each session request. The session identifier is returned to the request source. The EPMO instructs the PO to use the EPO when the PO is generated. This instruction is required in multiple EPO, but the method of determining the EPO to be bound is the same as that of EPMO.

Request for generation of filter object (FIG. 9)
(8)) Next, request the PO to generate a filter object (FO). At this time, the PO requests the FF to generate the FO. At this time, the FF attached to the EPO bound to the PO is used. The identifier of the generated FO is returned to the FO generation request source via the PO.

Setting of Filter Value (FIG. 9 (9)) Next, the PO is requested to set a filter value in the FO using the FO identifier as a parameter. Note that the event type name stored in the filter object (that is, the event type name to be filtered)
It is possible to selectively request the ETO to check whether the data structure (filter value) of the FO is correct, using the key as a key. If not, an error occurs. However, when a wild card is specified, this check processing is not performed at all.

Filter Registration (FIG. 9 (10)) Next, after setting a filter value in the FO, the filter registration is requested to the PO using the filter identifier of F as a parameter. At this time, the filter identifier is returned to the registration request source. With this as a trigger, it becomes possible to receive events. Note that a plurality of filters can be registered through one PO. (For this, a plurality of different FOs are registered as filters through one PO, or the same FO is registered as a filter a plurality of times. However, all filters registered for one PO have an “OR relationship”.

Event Transmission (FIG. 9A) Next, the event sender transmits an event to the PO. At this time, the PO can selectively request the ETO to check whether the data structure of the event is correct, using the event type name stored in the event as a key. When this check process is selected, if it is correct, the process proceeds to the next process (FIG. 9B), and if it is not correct, an error occurs.

Event collation request (FIG. 9B) Next, the PO transfers the event to the EPO. At this time,
EPO creates a thread. Note that a thread is generated for each event, and each thread performs multiplex processing of the event.

Collation with Filter (FIG. 9C) Next, the thread (EPO) performs filtering by collating the event with the filter. These include exact, partial, and weighted matches,
Can be specified when setting the filter value.

Starting of a proxy object (FIG. 9)
(D)) Next, as a result of matching with the filter, when the event passes the filter, the corresponding PO is activated and receives this event. At this time, the PO can selectively register the received event type, value, event ID, and the like in the SO. From this information, the SO can measure the firing rate of the event (for each event type and each event) and the highly reputed events that are prevalent in the EP.

Activation of event receiving object (FIG. 9)
(E) Next, the PO activates the event receiving object and passes the event to the event receiving object. This corresponds to the firing type (interrupt type) event notification.

Look-in type event notification (FIG. 9)
(F) On the other hand, instead of the PO activating the event receiving object, the event receiving object itself can also take out the event spooled in the PO corresponding to the event receiving object. This corresponds to a look-in type event notification. There are various triggers for activating the event receiving object depending on the service form. As a typical example, a case in which an end user makes a content proposal request to the event receiving object is considered.

<Filter Management Method> Next, a filter management method in each EPO will be described.

First, a session for receiving an event is established. At this time, one PO is generated for each session request, and this PO is bound to any one EPO. Each EPO is accompanied by one FF. As a result, the EPO used by the PO is uniquely determined, and all subsequent processing is performed via the PO (event receiving session).

Next, an FO is generated, and a filter value (a type of an event to be received and an acquisition condition thereof) is set for the FO. Subsequently, a filter is registered using the FO identifier as a parameter. At this time, the FO identifier is stored in each filter. Each EPO manages the filters registered via the PO based on the following rules.

First, referring to the FO identifier stored in the filter, the “type of event to be received” set in the FO is referred to. Subsequently, the filters are classified for each type of event to be received, and the filters classified for each event type are further classified and managed for each PO.

Referring to FIG. 11 regarding this management rule,
A case where a filter is registered via PO1 will be described. Here, it is assumed that “event type X” is set as the type of the event to be received in the FO specified at the time of filter registration. At this time, EPO
Corresponds to the filter 1 in FIG. 11, and similarly, the filter registered via the PO2 corresponds to the filter 2. In each PO, a plurality of filters can be registered. However, the registered filters have an “OR relationship”.

First, the event of the event type X is EP
When it arrives at O, matching with filter 1 is performed. As a result, when the filter 1 fires, the PO1 is activated.
Next, matching with filter 2 is performed, and as a result, when filter 2 fires, PO2 is activated. At this time, since the filters 2 and 3 have an “OR relationship”, the matching with the filter 3 is not performed. By using such a filter management method, each E for one event
The number of times of the collation processing at the PO can be basically made equal to or less than the number of POs (the number of reception sessions).

<Event Routing Method> Next, an event routing method will be described.

The EPO (SI-SW) accommodates event senders and receivers (entities such as terminals) in a star form via a session. Furthermore, EPO (SI-SW)
Matches the filter registered by the event receiver (event receiving object) with the event sent by the event sender, and as a result, notifies the event only to the event receiver corresponding to the fired filter (matching event reception (Delivery of the event only to the person).

Therefore, when the number of event senders (the number of events) and the number of event receivers (the number of filters) increase, the processing capability of the EPO becomes saturated in proportion thereto. Therefore, the SION architecture provides a multiple EPO as a means for realizing an EP with high scalability. Multiple EPO refers to the number of EPOs
The purpose of the present invention is to achieve a high scalability of EP from the following two viewpoints.

The first point is load distribution and autonomous distribution. This is to distribute the load of event filtering processing by distributing event senders and receivers to a plurality of EPOs, so as to prevent a bottleneck factor accompanying processing concentration. . Further, each EPO achieves distributed coordination by a mechanism that can operate autonomously without being affected by other EPOs.

The second point is reduction of network traffic and optimization of the filtering process. This is EP
This is to minimize the amount of communication by not transferring unnecessary events between Os, and to reduce unnecessary filtering processing.

In FIG. 10, for EPO3 • 33,
It is assumed that a filter of event type X is registered as a type of an event to be received. Here, when an event of event type X is sent to EPO4, it is necessary to transfer this event to EPO3 via EPO2. At this time, the event must not be transferred to EPO1 in which the filter of the event type X is not registered. What controls such event routing between EPOs is a shared link object (SLO), which corresponds to the SI-R described above.

Hereinafter, the SI-R will be described in detail.

First, at the time of initializing an EP, an SLO is generated in association with each EPO based on physical link information (EPO topology). For example, in FIG.
, Three SLOs are generated. These correspond to SLO2,1, SLO2,3, SLO2,4 in the figure. This S
LOi, j establishes a shared link (SLi, j) for transferring events from EPOj to EPOj. That is, as shown in FIGS. 9 and 12, SLOi, j is ELOi, j.
By establishing an event receiving session with POj, and establishing an event transmitting session with EPOi, a shared link SLi, j, which is a logical link for event transfer, is established. , Means the establishment of a session by SLO at the time of initialization of the EP, and does not include the filter registration processing).

After the initialization of the EP, the event receiver
It is possible to establish a session to P and register a filter via the session. At this time, an event path is set according to the established shared link. For example, in FIG. 12, an event receiver (Event
When the receiver 3 registers a filter for performing event type X event reception in the EPO 3 via the PO 3, the PO 3 registers the event type X filter in the EPO 3 and notifies the SLO 3, j ( Here, SLO3,2) is notified, and SLO3,2 is SL3,2.
Is used to register a filter of event type X for EPO2. This is performed via the PO of the receiving session assigned to SLO3,2, as described above. Similarly, this PO indicates to that effect that SLO2,3
Is notified to other SLO2, j except for. SLO2, j
(J ≠ 3) registers the filter in EPO using SL2, j. The process is repeated in the same manner until all EPOs are set to the path for the event X.

A series of paths established for the event type X is called an event path. this is,
The filter registration via PO3 is a trigger, and the event path setting request for each event type sequentially and autonomously propagates to all EPOs. That is,
Each EPO needs to recognize only the adjacent EPO.
For this reason, it is possible to establish the event path with a simple and unified autonomous logic as compared with the event path setting / management method by centralized management and broadcast of the event path.

FIG. 13 shows the registration status of the filter in the EPO 1 at this time. As a result of the event receiver 3 registering the filter via PO3, filter 1 becomes EPO1.
Will be registered. Setting an event path refers to registering a filter for event transfer in a series of EPOs based on shared link information. Also,
In the filter registered by the SLO, only the event type name to be received is set, and the acquisition condition is not set.
Filter only the event type name.

In this situation, the event receiver 2 receives the P
Via O2, filter the event type X to EPO
When the event path is registered in EPO2, the setting of the new event path spreads to all EPOs as described above. As a result, the filter 2 is registered in EPO1, and the filter is registered every time an event path setting request is made. Will be done.

At this time, when an event of the event type X is transmitted to the EPO1, the filter 1 fires and the SLO
2,1 is activated. SLO2,1 reports this event as EPO
SLO3,2 is activated by sending to SLO2. Further, the event is transferred to EPO3 via SLO3,2. To prevent infinite transfer of events between SL2,3 and SL3,2, the event is
As one of the control information, a maximum of two identifiers of the passed EPO are stored in the latest order.

As described above, since filter 1 and filter 2 have an OR relationship, when filter 1 fires, comparison with filter 2 is not performed. Therefore, even though the filter 1 exists, it is possible to prevent the redundant overhead of the filtering process caused by newly registering the filter 2 from occurring at all. This means that when an event path is set, there is no need to rebuild all event paths including the existing event path, and a simple and unified event path autonomous setting becomes possible. .

If there is a session established by the event receiver in EPO1 and a filter registration via the session (corresponding to the filter 3 of POn), after all the filtering processes corresponding to SLO are completed, Is performed. That is, the event transfer processing to another EPO is performed with priority, and then,
The collation processing in own EPO is started.

A further effect of the event routing method described above is that it is not necessary to reconstruct an event path when canceling filter registration. For example, when the event receiver 3 cancels the registration of the registered filter via the PO 3, the cancellation request sequentially and autonomously spreads, similarly to the case of the registration. As a result, in EPO1,
Only the registration of the filter 1 will be cancelled, but the filter 2 survives (hereinafter, the filter 2 forwards the event instead of the filter 1). Event path consistency is guaranteed.

By using such an autonomous distributed routing control method, it is possible to easily realize interconnection and distributed coordination of EPO. Accordingly, a transition from a small network to a large network, a transition from a local network to a global network, and the like can be smoothly performed. Also,
Global networking with a bottom-up approach can be easily achieved with common logic.

FIGS. 14 to 17 are diagrams for explaining the SI-R in the physical link having the ring type coupling.

For example, as shown in FIG. 15, in a physical link having a ring-type connection, EPO2 is EPO1,
It expresses that you know the existence of EPO3. As described above, the multiple EPO aims at improving the scalability by distributing the load of the event matching process in the EP.

The EPMO is selected from the list of hosts capable of generating an EP specified in (1) of FIG.
The host that generates O is dynamically determined, and EPO is generated there. At this time, each EPO is always accompanied by one filter factory (FF) and one statistical information collection object (SO), and these are generated by the SI-S
W. Further, one shared link object (SLO) is generated for each EPO according to the physical link. For example, SLO2 and SLO3 in the figure are generated for EPO2. This corresponds to SI-R. The method of determining the activation destination of EPO is the same as that of EPMO, but it is also possible to fix the EPO used for each event type. Note that the EPMO generates an event type factory (ETF) in the EP. E
Within P, a unified event type namespace is guaranteed by the ETF.

The details of the SI-R will be described below.

First, at the time of EP initialization, an SLO is generated accompanying each EPO based on physical link information (EPO topology). For example, in FIG.
SLO2,3 is generated for O2. This SLOi, j
Establishes a shared link (SLi, j) for transferring events from EPOj to EPOi. That is, FIG.
As shown in FIG. 16 and FIG. 16, SLOi, j establishes an event reception session with EPOj, while
By establishing an event transmission session for i, a shared link SLi, j, which is a logical link for event transfer, is established.
This means that the session is established by the SLO when the EP is initialized, and does not include the filter registration process.) As a result, a unidirectional ring-shaped shared link SLi, j is established.

After the initialization of the EP, the event receiver sets the E
It is possible to establish a session to P and register a filter via the session. At this time, an event path is set according to the established shared link. For example, in FIG. 16, the event receiver (Event
It is assumed that the Receiver 3 registers a filter for receiving an event of the event type X via the PO 3 in the EPO 3. At this time, the PO3 registers the event type X filter in the EPO3 and notifies the SLO to that effect.
Notify 3,1. At this time, SLO3,1 is given as a parameter that the source of the filter registration request is EPO3. SLO3,1 uses SL3,1 to register an event type X filter for EPO1. This is performed via the PO of the receiving session assigned to SLO3,1, as described above. Similarly,
This PO notifies the SLOs 1 and 2 of that fact.
SLO1,2 registers a filter in EPO2 using SL1,2. The process is repeated in the same manner until all EPOs are set to the path for the event X. Note that this processing is performed by a filter registration request source (here, EP
This is repeated until immediately before O3). That is, SLO2,3
Does not register the filter in EPO3.

FIG. 17 shows the registration status of the filter in the EPO 1 at this time. As a result of the event receiver 3 registering the filter via PO3, filter 1 becomes EPO1.
Will be registered. Setting an event path refers to registering a filter for event transfer in a series of EPOs based on shared link information. In addition,
In the filter registered by the SLO, only the event type name to be received is set, and the acquisition condition is not set.
Filter only the event type name.

In this situation, the event receiver 2 has
Via O2, filter the event type X to EPO
When the event path is registered in EPO2, the setting of the new event path spreads to all EPOs as described above. As a result, the filter 2 is registered in EPO1, and the filter is registered every time an event path setting request is made. Will be done.

At this time, when an event of the event type X is sent to the EPO1, the filter 1 fires and the SLO
3,1 is activated. SLO3,1 reports the event as EPO
SLO2,3 is activated by sending to SLO3. Further, the event is transferred to EPO2 via SLO2,3. In order to prevent the event from going infinitely, the event is one of the control information.
The identifier of the EPO in which the event has occurred is held, and when the event circulates and returns to the event-originating EPO (SLO), the event is discarded.

Next, an event routing method different from the above-described event routing method will be described. This routing method uses shared links (logical links).
Are established in the same manner as in the method described above.
This event routing method differs from the method described above in that no event path is established, and SLOi, j
At the same time as establishing the shared link SLi, j. At this time, a wild card is specified as a type of an event to be received in the registered filter. As a result, all events are set as transfer targets, and an event path for each event type is not established.

By specifying a wild card in the semantic information as described above, ring-shaped shared link SL
Since the event circulates in i and j, the event can be delivered to all EPOs.

<Federation Method> Next, the federation method will be described with reference to FIG. The federation agent (FA) is an agent that establishes a federation between event places, and corresponds to the above-described SI-GW. For example, an event place (Event Place) A is an event place (Event Place)
Place) A case where a federation is established for B is considered. First, an FA belonging to event place A registers a filter for event place B. At this time, the event sender belonging to the event place B sends an event, and as a result, when this filter fires, the FA autonomously starts. This can regard the FA as one event recipient belonging to event place B. Next, the FA retransmits the acquired event to the event place A to which the FA belongs. this is,
FA can be considered as one event sender belonging to event place A.

As described above, the Federation between event places can be easily realized by using the FA having both roles. That is, it is possible to realize the federation between the event places with the same control logic as that of the single event place. Using this mechanism,
By interconnecting the event places, which are one basic configuration unit, a global collation network can be constructed by a bottom-up approach, and sharing of events across event places can be realized. Note that event place A and event place B
Have different ontologies, the FA belonging to the event place A converts the event acquired from the event place B into the ontology of the event place A, and then sends the event to the event place A.

[0099] When event transfer is performed across different ontology systems, ontology conversion is required.
As a conventional technique for performing this conversion, when a standard ontology is defined and an event is transferred to another event place, a method of transferring the event after temporarily converting the event to a format conforming to the standard ontology, and a method of transferring the event There are methods such as preparing an ontology conversion table for the number of combinations in advance.

However, the conventional method lacks flexibility to cope with dynamic federation of event places (dynamic start and release of federation). Therefore, in the present invention, as shown in FIG.
Holds only the difference (conversion information) from the ontology information of the adjacent event place in the ontology conversion table. In other words, this is a method in which each FA stores the conversion information in a distributed manner, and assures the consistency of the ontology system as a whole. This makes it possible to easily cope with dynamic federation between event places, but on the other hand, every time an event crosses an event place, an ontology conversion process occurs. It has the feature that processing overhead increases.

<Community and Evolved Network> Next, a community service, which is one of the killer services of ION1, will be described. An entity in a community service is an autonomous decentralized operation entity that can dynamically determine an activity mode by repeating learning, evolution, degeneration, and disappearance based on its own policy. Communities provide an efficient forum for such entities to communicate. In other words, entities in the community dynamically search for and identify entities that should communicate with themselves or that affect their behavior.
It is possible to discover / specify and interact with the specified entity.

This community can handle entities having the following characteristics in particular.

(1) An extremely large number of entities exist in a community with an extremely small granularity (an unspecified number of entities).

(2) The attribute of the entity changes in real time. Typical entity attributes include location information, time, and the like.

(3) The behavior of the entities in the community is not regular, and it is difficult to predict the behavior.

(4) Participation in the community, departure from the community, disappearance, duplication, etc. occur frequently and irregularly.

(5) The entities in the community are:
It is necessary to meet each other in real time based on policies, attributes, scenarios, and the like.

It is not easy in terms of performance to manage entities having such characteristics by a server or a mediator (broker) and to search and discover each other in real time. S
The ION1 EP is positioned as an execution environment of a community having such characteristics. That is, the community is a meta execution environment of the EP, and provides a place of communication with a higher level of abstraction than directly using the EP. By using the EP in the execution environment of the community, all the entities in the community can directly find the entity to communicate with without going through the broker. This is because communication of entities in the community is implemented as sending and receiving events in the EP.

FIG. 19 shows a conceptual model of a community. A user agent (UA) and an information and service providing agent (ISA) correspond to entities in a community. The UA is an agent that behaves autonomously as a user's agent.
It dynamically determines its own behavior according to location information, situation, tendency, etc., and interacts with ISAs and other U
Search for A and interact with them. An ISA is an agent that acts autonomously as an agent of an information provider or a service provider.
Search for UAs and other ISAs to interact with.
That is, a user suitable for providing his / her information is searched for and specified.

On the other hand, the community agent (Com
A) is an agent that manages the community. The EP operator sets the SION-
Controls and operates the SION via MT. Therefore, C
The omA can be considered as an agent of the EP operator. Basically, the operational policy of the community is defined by ComA. For example, UA, ISA
Authorization, such as joining, leaving, extinction, duplication, etc. to the community for such entities, understanding and controlling the information distributed within the community (such as deleting unsuitable events), statistical information within the community (trend information, reputable information Etc.) based on their own management policies.

Further, in order to achieve the guarantee of high scalability and reliability of the community, SION control such as increase / decrease, withdrawal, and migration of EPs and EPOs is executed according to the load condition and the failure condition. That is, by combining ION1 and ComA, ION1 learns from the autonomous decentralized network,
It evolves into an evolutionary network that can grow and evolve.
In this way, the ComA controls the behavior of the entities in the community and plays a role in self-organizing SION1. Further, the collaboration between the communities enables the sharing of information between the communities. For example, among the information distributed in the community A, only the top 10 most popular can be distributed to the community B. The processing flow is shown below.

First, the ComA of the community B instructs the FA of the event place B to "distribute only the top 10 most popular information among the information distributed in the community A to the community B". I do.

Next, the FA inquires of the event place A about the top ten event types. In response to this, the event place A inquires the subordinate statistical information collection object (SO) and sends the result to the FA.
Return to.

Next, the FA creates an ontology conversion table based on the acquired event type, and sets a filter for the event place A. Hereafter, F
A can receive the event from the event place A.

Next, the FA converts the event obtained from the event place A into an ontology based on the ontology conversion table, and sends it to the event place B.

According to the embodiment described above, the following two effects can be obtained.

First, the SIO is placed on the distributed object environment.
N network environments can be easily constructed.

Second, by allowing the service application to participate in the community as an entity,
It is possible to easily send out an event or to pick up a necessary event, so that mutual communication can be achieved.

As described above, the following effects can be obtained with the SION.

An event that has been distributed only in another event place can be taken into its own event place by a federation mechanism between event places via the FA. Conversely, by sending an event to another event place, it is possible to advertise the event distributed in the own event place. in this way,
Events can be shared between different event places, and interoperability between event places taking into account the ontology makes it possible to construct a global autonomous decentralized collation network based on a bottom-up approach.

The multiple EPO mechanism makes it possible to distribute the load of the filtering process to a plurality of EPOs, and the autonomously operating event routing mechanism between EPOs makes it possible to minimize network traffic. Become. This results in E
The total throughput of P can be scalably improved.

It is possible to directly search for and find an entity suitable for itself without going through a broker. For example, an information provider can specify a user who is suitable for the information provided by himself without knowing the existence of the user. Similarly, the user can search for and find an information provider suitable for his / her taste without knowing the existence of the information provider. That is, the user and the information provider are equivalent to each other. As a result, information can be transmitted in real time according to the own policy without relying on a specific broker. Further, when the number of entities to be searched is enormous or when the entities frequently enter and leave the search target domain, the search technique based on the non-broker model is particularly effective.

In the SION, the end point of the semantic information is a network. On the other hand, in a method of performing a peer-to-peer connection between terminals, the terminal of the semantic information is the terminal, so that the contents of the terminal are disclosed to the outside. Therefore, SION can realize higher security and privacy protection than the latter method.

Next, an embodiment of the present invention using a semantic information network system having the above contents will be described.

FIG. 20 is a system diagram for explaining services by the mailing list management method according to one embodiment of the present invention. This service is realized by information exchange between a plurality of mailing list service users. Further, in the present embodiment, the semantic information network 10 in FIG. 20 is realized using the above-described event place, but the method of realizing the semantic information network 10 is not limited to this.

In the mailing list operation system of this embodiment, the terminals 31 to 3 of the mailing list users 1 to 4 are used.
4 are connected via the semantic information network 10.

Mailing list user terminals 31 to 34
Function as transmitting terminals for transmitting e-mails to the semantic information network 10 as events, respectively.
In order to selectively receive an email sent as an event, it also functions as a receiving terminal in which a filter including an event type and an acquisition condition is set.

Each of the mailing list users 1-4 installs CORBA-compliant middleware such as an ORB and the above-described event place factory generating mechanism in terminals 31 to 34 such as PCs to be used, and stores the event place on its own terminal. Create or access an event place on another network node to establish a session,
It is assumed that it is connected to. It is also assumed that an event type as shown in FIG. 21 is registered in the semantic information network 10.

For the registered event types, “mailing list service” is defined as the event type name, and “name” is defined as the event property name. In this event property, “string type” is defined as an event property value.

Next, the mailing list management method of this embodiment will be described in detail with reference to the drawings. The numbers in parentheses in FIG. 20 are assigned to the information to be transmitted in the order of occurrence, and the operation of the present embodiment will be described in the order of the numbers.

(1) The users 1 to 4 who want to use the mailing list enter a mailing list name that functions as an identifier for uniquely specifying the mailing list by using a user application or the like. FIG. 22 shows an example of a user application screen displayed on the terminals 31 to 34 when this input is performed. Here, a case where “business model patent study meeting” is input as the name of the mailing list is shown as an example.

Then, when the user application sets the mailing list name as a filter in the semantic information network 10, participation in the mailing list is started. FIG. 23 shows an example of a filter condition set in the semantic information network 10. In FIG. 20, the filters to be set are conceptually indicated by black circles.

At this time, there is a case where the event place operator or the representative of the mailing list needs permission of participation.

(2) If the user who has registered in the mailing list wishes to send an e-mail to another user registered in the mailing list, the user (here, user 1 in FIG. 20 is used as an example) The user inputs a mailing list name, which is the name of a participating mailing list, and a text of a mail to be transmitted using a user application or the like. FIG. 24 shows an example of a user application screen on the terminal 31 displayed when the mailing list user 1 tries to send a mail. At this time, the user application transmits the input mailing list name and mail to the semantic information network 10 as an event. FIG. 25 shows an example of an event generated by the user application program.

At this time, the user application is set to the mailing list name entered here and the user application has already been set in the semantic information network 10 by the method shown in (1) above. By comparing with the property value corresponding to the property name "name" of the filter having the event type of "mailing list service" and adding a mechanism to permit the transmission of the above event only when both match, an outsider Can be prevented from sending mail to the mailing list.

(3) Mailing list users 2 to 4
Receives the event transmitted by the user 1 from the semantic information network 10 by the firing type or the look-in type via the user application or the like because the filter set in the semantic information network 10 matches the event. I do. As a result, mail distribution from the user 1 to the users 1 to 4 is performed, and the mailing list service is realized without an intermediary. In this case, since the user 1 has also set the filter, the user 1 receives the mail sent by himself.

According to the mailing list management method of the present embodiment, the user can participate in the mailing list by setting the name of the mailing list he / she wants to join as an event property in the filter.
Also, by canceling the setting of the filter, it is possible to withdraw from the mailing list to which the user has joined. In this case, the user joins the mailing list at the same time as setting the filter, and withdraws from the mailing list at the same time as canceling the filter setting. Can be handled.

Further, since it is possible to participate in the mailing list without notifying the mediator of his / her own information, the privacy of the user and the security of the confidential information are improved.

Further, since the operation of the mailing list can be performed according to the agreement between the users, it is easy to reflect the policy of the user in the operation of the mailing list.

Also, in this embodiment, an outsider who does not set a filter for receiving mail from the mailing list at his own terminal transmits mail to users participating in the mailing list. You can do it. However, there are cases in which an email from an outsider who does not participate in the mailing list is not desired to be delivered to each user. In such a case, by setting a filter, the user application may be set so that the mail can be transmitted only to the participating mailing list. Alternatively, it is also possible to eliminate outsiders by adopting techniques such as adding an electronic signature to the mail and encrypting the mail.

According to the mailing list management method and management system of the present embodiment, mail can be delivered in real time, so that text data is exchanged instead of mail, which is conventionally performed. Not only a mailing list service but also a chat (chat) service for performing a short conversation between a plurality of participants can be realized by a similar method and configuration.

In order to realize this chat service, text data to be transmitted to another user is transmitted from a terminal of a user who wants to participate in the chat service, together with information indicating the chat service which wants to participate. Sent to the semantic information network as an event. Then, the terminal in which the information indicating the chat service is set as a filter receives and displays the sentence data transmitted as the event, thereby realizing the chat service.

According to such a configuration, a chat service in which user participation and withdrawal are performed more complicatedly than a mailing list can be realized without requiring an intermediary. Real-time performance of sending and receiving text data between users, joining and leaving chat services,
The operation according to the user's own policy becomes possible, and the security of the user's confidential information can be improved.

[0144]

As described above, the present invention has the following effects. (1) The mailing list service can be used without an intermediary. (2) It is possible to respond in real time to frequent occurrences of participation and withdrawal from the mailing list. (3) A mailing list can be managed based on the user's policy. (4) The security of the privacy and confidential information of the user is improved. (5) The load is distributed due to the absence of an intermediary. (6) No brokerage fee is charged.
