The detailed description of optimum implementation
Operating in the application program on the various computing machine in the network intercoms and and then cooperation mutually mutually by the message product such as the MQSeries message queueing software of IBM Corporation.Relevant information queuing and the message queueing product that can buy are at " Messaging and QueuingUsing The MQJ " B.Blakeley, H.Harris ﹠amp; R.Lewis, McGraus-Hill, 1994, reach the following publication that obtains from IBM Corporation: " An Introduetion toMessaging and Queuing " (IBM document number GC33-0805-00) and " MQSeries-Message Queue Interface Technical Reference " (IBM document number SC33-0850-01) description is arranged all.Computing machine use the mutual communication of message queueing the network of process can be an internet, an internal lan or any computer network.IBM and MQSeries are the trade marks of IBM Corporation.
The MQSeries information software product of IBM Corporation provides the message support of issued transaction formula, it is according to a kind of messaging protocol message in logical unit of work synchronously, this agreement even also can guarantee to send once and one-shot message transmission under the situation that system and communication are broken down.The MQSeries product provides the transmission of the message that can guarantee in order to following method: before message confirms to be received the security of system storage as yet, can finally not delete the message of storing in transmitting system; And the Restoration Mechanism of using complexity.Submit to confirming successfully to store before message transmits, deletion message and in receiving system, insert message and be in " suspection " state always from the storage of transmitting system, and can when fault takes place, withdraw from automatically.This message transmission protocol and relevant issued transaction notion and Restoration Mechanism thereof all have description in International Patent Application WO 95/10805 and United States Patent (USP) 5465328.Quote them as a reference at this.
The communication support makes each application program message can be given the input queue of other any destination application between the message queueing program that is provided by the MQSeries product, and each intended application can both be taken out these message from its input queue asynchronously and handled.So just can be for the message of guaranteeing transmission be provided between each application program that distributes in dissimilar computer networks, but there is very big complicacy in the mapping of possible connection between the application program.
This complicacy can be simplified greatly by comprise a Communication Hub in network structure, and wherein, all other systems all are connected to this hub to replace the direct connection between all systems.On Communication Hub, can give information agent functionality to obtain the integrated of smart message route and application program.The Message Agent function typically comprises following ability: according to the knowledge of the information requirements of business rules and different application, use is included in the ability that the message route is determined on message " theme " information intelligent ground in the message header, and uses knowledge that the message format of destination application or system the requires ability with the transforming message form.The MQSeries integrator software product of IBM Corporation provides above-mentioned agent capability, and it uses the MQSeries message product of IBM that the service that exchanges messages between each application program is provided.
If we adopt a kind of hierarchy chart of being made up of various parts, then near user's top layer, Message Agent is in application program and message and transmits next level between the software application program then.
According to the present invention, Message Agent software product and software part are suitable for publication/booking mechanism that support information transmits, and this mechanism is extended to comprises the more complicated processing of message content.
Fig. 1 illustrates according to the Message Processing flow process of passing through Message Agent 30 between publication application program 10 of the present invention and the subscriber's application program 20 and basic overview.The Message Agent 30 of optimum implementation is realized as a software part according to the present invention, it is with operating in message manager 90 coordinated manipulations on the computer system 100, wherein, all publication application programs all are connected in this system by a communication network.But this agent functionality may be distributed in a plurality of Message Agent parts that network connects, as next section to discuss.Therefore, connection message agency (no matter being single parts or distributed) is used to receive all publication message.Each application program and message manager 90 are connected, in order to the complicacy by network communication between the handling procedure, and each Message Agent also be installed in local computer system on message manager 90 be connected.
As mentioned above, replace the single agency on the communication multiplex adapter, hub can be formed a set of the distributed agent 30 of communication each other.These agencies 30 can sharing users tabulate, and the extendible distributed agent structure of a redundancy is provided.Use of the present invention to the sign of message content characteristic and with reference to each processor function and the characteristic information, select one in a plurality of processors to make the Message Processing optimization in distributional environment, the Message Agent service that above-mentioned distributed agent mechanism is provided is enhanced.For example, the part of functions of Message Agent is in the system of a direct connection database, and SQL query efficient just can obtain optimization by all giving this system with all SQL query.If the second portion function of Message Agent is in the system with specific image processing function, then all message that contain image just can all be sent to this system.
For the ease of understanding, following narration only relates to a single Message Agent that is installed on the individual data disposal system, and wherein all publication message are all delivered to this system.When Message Agent was received a message, the message analysis parts 60 in Message Agent at first checked 120 to find a theme or a subject identification to message header.Message publisher application program may indicate a message subject or theme, for example " stock/computing machine/IBM " or " stock/motor/GM " character string is input in the domain of dependence of message header to indicate the stock price that this message subject is respectively worker BM company and Societe D' applicantions Generales D' electricite ET DE Mecanique SAGEM.The user also may be in the same way to specify them to wish the message subject of receiving, for example specify " stock/computing machine/* " obtaining the stock price of all Computer Companies, or " */IBM " is to obtain all relevant message of IBM Corporation.
Message Agent comprises a regulation engine 40, and it will require tabulation to compare from any subject identification and the user profile that message header retrieves, and wish to receive this message to discern which user.In addition, this subject identification is also compared with the subject identification tabulation 130 that a known hint has some non-alphanumeric message content.In this example realized, message was published application program and is provided information to Message Agent, comprises subject identification the encoding list (as the part of enrollment process), used the subject identification coding when publishing the message that contains the non-alphanumeric content in publisher.
Perhaps, enrollment process may comprise that publisher's appointment will only comprise the message subject of text based content, there is no need this message is further analyzed to determine whether to contain any non-content of text in order to indicate.
The second, unless attempt retrieval and explain that how the message subject sign can determine finally that the analysis component 60 of Message Agent scans 140 message contents and removes to seek the byte sequence of representing the special content type outside the processing messages.Analysis component 60 compares 150 with the dictionary of the byte sequence of message content and the byte sequence of the special construction of representing special content one type.GIF for example, TIFF and jpeg picture, each all has the attribute byte sequence.The content scanning step can sound recognition and image, and resolves pixel format.Message also may comprise program code, and for example HTML (HTML) or XML (Extensible Markup Language extension flag language) encode, and they have been described and have been internet Web-browser data presented form.The message content scanning step is easy to reference to they corresponding sign dictionaries with identification XML or HTML.
After finishing this inspection, the any message that is masked as the non-alphanumeric message content is all sent the input buffer of a multi-media module of suitably selecting in 170 to one groups of multi-media modules 70, wherein the selection 160 of this module is to be image or sound according to the non-alphanumeric content, or other data type is carried out.
The example of the XML message content that utilization provides above, inspection XML content just can be pointed out the existence of specific content of multimedia, disclose and how to determine the relevant content characteristic of processing messages, and under some environment, the XML form can also be provided for suitably handling the required one or more coding modules of content that identify.
Message Processing set 70 that comprises the multimedia processor module is preserved as the object in the library of object 80, and response agent requires the message of 70 pairs of receptions of a certain concrete processor module to handle the decision of operation and instantiation.Whether the selected module of Message Agent 30 usefulness inspection is moved and (be that is to say, when receiving previous message, the instantiation of this module) with the selection 160 of response message processor module 70, if move, then queuing is handled by this processor module in the input-buffer district.If desired processor module is off-duty still, it is by instantiation so, and message is sent to the input-buffer district of this processor module and is processed.
In a simple embodiment of the present invention, all message that contain image content are all passed to a single presentation manager module; Similarly, all message that contain voice data are all passed to a single Sound Processor Unit module; And but the message that contains other recognition data type is all passed to the corresponding processor module that can handle the type message.If contained several dissimilar contents in the message, following situation will take place: transmit this single message through each different message handling device module, go to finish series of processing steps.The message that contains executable code was delivered to the processor module that can finish authentication function (as the digital signature checking, or virus checking) before allowing to publish, in order to avoid the user is subjected to the infringement of undesirable program code.This measure meaning person who each message content is had a single message handling device module: input message is carried out relative simple analysis, just can select a suitable message handling device module.
In one embodiment of the invention, the message handling device module of a selection will be finished a series of general processing operations,, all message that are sent to this processor module all be finished identical operations that is.But this is not best embodiment for many message handling device modules.
In an optimum implementation of the present invention, the processing procedure that selected message handling device module is finished is by the special characteristic decision of the message of specified particular requirement of each subscriber's application program and reception.Therefore, after having selected a message handling device module, special subject and the type in the message received in response, Message Agent determines that 180 which user application have indicated requirement and received a message, all in order to produce a task description, it is imported into selected message handling device module with message to each subscriber request then.
Then, selected message handling device module is carried out 190 sequence of operations according to relevant task description, and with the message return messages agency of the derivation that produced, to be distributed to relevant subscriber.
In further embodiment of the present invention, the actual selection of message handling device module oneself depends on the appointment requirement of subscriber's application program, this means: with reference to subscriber request is to be finished as a part of selecting step by the agency, rather than the step of back.
Now, function of the present invention will be described with reference to several Message Processing according to the present invention and agency's example.
Please consider such computer system, it is set to publish the message that contains the earth surface image that is photographed by orbiter.The tissue that obtains this message can be to receiving that being included in interested other tissue of special data of taking in the image provides subscription service, shares retrieval and handle the expense of these data.Publish application program for one in this first system and produce the message that contains original shooting image termly, and give Message Agent these message.This Message Agent analysis message that 120-150 received, and identify and in this message, exist image (as mentioned above, any discernible message subject sign is compared with known theme, and discern in conjunction with scanning message content).
Response identifies an image, and Message Agent determines that 160 should transmit the message to the message handling device module that can handle image.The agency uses subject identification checking 180 customer requirements records-will receive and the requirement for information about of this subject identification to determine which user has registered then, and determines what specific data demand these users have specified.For example, first user has registered such requirement to Message Agent, when Message Agent is received the message of the subject identification that contains a certain specific publisher organization name, to this subscriber a message is set.This subscriber also may specify: all message of receiving from this publication tissue all should be handled these image contents, to produce an image that can show the derivation of the crops classification that can discern from original shooting image.In addition, the subscriber also may specify an output type, and it requires message is handled, and message conversion is become the desired type of subscriber.For example, if subscriber's program is connected to an audio output device, it just may require all message all to convert a waveform output file to, and another subscriber's application program may be an e-mail program, and it then requires message to transmit as email record.
Produce a task description, it has been described on request mode the image content that receives in the message has been handled the sequence of operations that will finish, and this task description and the message that received transmit 170 together and gives and selectedly can handle visual message handling device modules then.This message handling device module will be carried out 190 above-mentioned a series of processing operations, return a new information that contains the new pictorial data of handling to Message Agent then.
This Message Agent is transmitted new information 200 then to having specified the subscriber of these information requirements.Requiring (under the control of regulation engine 40) according to subscriber information is very similar with the process that the message of final conversion is sent to the subscriber to the process that prior art is finished.Therefore, the present invention just can carry out the specific processing of content type to message content, message is finished suitable processing do not rely on single specific Message Processing structure joined and only use business logic to discern traditional publication/reservation system of relevant subscriber.
In the optimum implementation of the present invention, message content types is used for selecting the message handling device module, and does not rely on the subject identification in message header.Analysis component 60 scanning message contents in the Message Agent (this can do in all cases, also can carry out when having only the query messages head to be not enough to determine to select which message handling device module).When this scanning step identifies an image in message content, this image can carry out a watermark retrieval process, the subsequent analysis watermark is enough to discern the information that select which message handling device module and should finish what operation to image to determine whether to have comprised.Like this can be so that before the specific customer requirements of investigation, just can realize the processor module of the present invention choice phase, the processing stage of may also having message content.
Similarly, also can extract and analyze to determine required processing operation the voice data in the message with watermark.
Message Agent according to optimum implementation of the present invention also can use the input message whether response agent receives of determining that depends on the logic that text based data in text based information and the message content in the message header are analyzed to have a special subscriber should receive message.In other words, except multimedia processing of the present invention aspect, the text-processing of finishing according to Message Agent of the present invention can also comprise the requirement of processing subscriber information, has for example indicated the stock price of only just notifying a certain company (Business Name) when stock price has surpassed a certain threshold value.The subscriber may specify " stock/computing machine/Business Name " as the subject identification that identifies from message header, and specify " price＞$150 " to receive the needed filtrator in a certain stock price territory in the message content as scanning, want to give this subscriber to determine message.Whether genuine mode is to carry out content analysis also can or to be similar to certain condition of test (for example " Business Name stock price＞$150 ") with the inquiry of utilization structure query language sign.
In the further example of realizing Message Agent operation of the present invention, content search can comprise that the content of multimedia analysis is to replace simple business logic known in the system of prior art.For example, the subscriber may register the interesting arbitrary figure that contains a red circle in the visual upper left corner of receiving, as a kind of mode of the possible trademark infringement of investigation, perhaps registration is interesting receives and an enough similar arbitrary figure of model image, or represents the set of diagrams of certain class image type to resemble.
It is known (for example, the image content of the IBM Corporation of describing in United States Patent (USP) 5579471 inquiry (QBIC) technology) that the user of the image characteristics that maybe will mate according to the model image describes the technology of carrying out the image contrast.Input imagery can be used as the inquiry to the QBIC catalogue that contains the classification representative, and the classification representative is the result of one group of range observation.Fuzzy matching algorithm can be set up the image in the message and the degree of closeness of a model image or desired characteristic.Can relatively strengthen subscriber's enrollment mechanism in traditional publication/reservation agents by multimedia feature definition and multimedia feature, just be sent to predetermined subscriber thereby only allow to have the message that satisfies subscriber's standard (in) by the given range of tolerable variance of specifying threshold to define.
Above-mentioned QBIC example shows, the message content Feature Recognition can comprise the several steps of separation, be exist (the using accurate coupling usually) of identification message content type to given byte sequence, and then (for example discern those image content characteristics outside above-mentioned identification byte sequence, whether content mates defined parameters, or not in certain tolerance with the model Image Matching).
After these steps, to make a decision, what for example will be finished handle, and how to do.In category of the present invention, relate to and how to carry out this step and have very big dirigibility.This decision can be used the method relatively not too flexibly of a storage or depend on a kind of dynamic approach method from publisher and user's input.The subscriber can specify the specific processing operation of required some that finish of message of deriving message to being used to produce when registering as a subscriber.Object lesson is described in front to some extent.
As mentioned above, the function of identification message content characteristic is passed to the logic of which message handling device module and the processing capacity that preferably also has one or more message handling device modules with determining with message, can in a software part that can substitute, realize, it is cooperated mutually with Message Agent, and controls its operation.By some functional separation being become the feasible energy of alternative parts (such as Java Bean or ActiveX parts) according to the performance of the special software parts that use with the agency with the modification Message Agent.This also allows to add at any time new function, and for example, but when some new message function times spent, the message characteristics dictionary that this is the new library of object of packing into makes Message Agent can discern this new message content types like this.
