METHOD FOR THE SAME

[Technical Field]

The present invention relates to a context cognizance enhancing message transform system, and method for the same. In the message conversion system and method, the context of text message is effectively recognized so that logic errors can be avoided in conversion of text message.

[Background Art]

Additional services related to message contents, which have been developed, are not commonly used because of a high recognition failure rate resulting from difficulties in recognition, mistaken recognition occurring from the simple word recognition, and the generation of wrong results.

That is, when automatically-set contents having an opposite meaning to what a user message intends to say are transmitted, this can be fatal to a paid service. Even in the actually commonly-used message service, the use of implemented recognition function has been stopped after persons in charge of the message service found such an error. In the case of Chinese messages in which a letter can serve as a word, such a problem becomes more severe because the same letter can represent a variety of meanings.

[Best Mode]

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. When it is judged that the specific description of related known function or constitution can cloud the point of the invention, the description will be omitted. Terms to be described below are defined in consideration of the functions of the invention and can differ in accordance with the intension of a user and operator or the practice. Accordingly, the meanings of the terms should be interpreted on the basis of the contents of the specification.

Figs. 1 to 2 show an embodiment according to the related art. According to a conventional message conversion system, when such a word as 'love' or 'angry' is present in a text message, the text message can be converted by using contents prepared for the word such that the emotion of a transmitter is recognized so as to bring about an interest, as shown in Fig. 1. However, the conversion to be performed by such simple word recognition includes a problem of logic error, as shown in Fig. 2. That is, the text message of a user has a meaning opposite to the automatically-set contents such that contents different from what the text message intends to say are delivered. Such a result can be fatal to a paid service. Even in the actual message service, the use of implemented recognition function has been stopped after persons in charge of the message service discovered such an error. In the case of Chinese messages in which a letter can serve as a word, such a problem becomes more severe because the same letter can represent a variety of meanings.

Fig. 3 is a diagram illustrating a communication network to which the invention is applied. As shown in Fig. 3, the communication network includes a service server, a receiver, a sender, an SMS G/W (gate way), an SMSC (short messaging service center), an MMSC (multimedia messaging system center), an MMS phone receiver, and MMS servers of other mobile-communication service provider. Specifically, when a message coming from the receiver is sent to the service server through the SMSC or MMSC, the service server combines components corresponding to the message so as to transmit to the sender. However, each service provider employs its own MMSC. That is, a multimedia message created by A mobile-communication service provider cannot be sent to B mobile-communication service provider. Therefore, the MMSC is connected to MMS servers of other mobile-communication service providers as well as the MMS phone receiver.

Fig. 4 is a diagram illustrating the configuration of a message conversion system according the invention. As shown in Fig. 4, the message conversion system 13 of the invention includes a message receiving section 20 which receives a message of a subscriber from the SMS center or MMS center 12; an subscriber authentication section 21 which checks through a subscriber DB whether the subscriber has joined the message conversion service or not, verifies setting items related to the message conversion service which are designated by the subscriber, and confirms the terminal information of a destination mobile-communication terminal receiving the message; a message discriminating section 22 having a filtering section 27 and an individualization unit 27 using a statistical method, the filtering section 27 analyzing whether the message passes through a filtering unit or not. Further, the message conversion system 13 includes a component extracting section 23 which extracts components, indicated by the verified setting item related to the message conversion service or the analyzed result, from a component/filtering DB 14 and a component combining section 24 which combines the extracted components with a subscriber message. The message combined with the components is delivered to the SMS or MMS center 12 through the message transmitting section 25. Further, the message conversion system 13 includes an Internet matching section 26 which receives the subscription of the message conversion service from a mobile communication subscriber through a mobile-communication terminal and/or the computer 16 and the Internet and provides a subscriber of the message conversion service with a function of wiring a short message through a web page, a function of setting various items related to the message conversion, and a setting/inquiring function corresponding thereto. The SMS center or MMS center 12 transmits a message of a mobile-communication terminal to the message receiving section 20 of the message conversion server 13, requests the message conversion server to convert a subscriber message into an SMS or MMS message, and transmits the converted SMS message or MMS message to a destination mobile-communication terminal.

The component/filtering DB 14 stores MMS data such as photos, sounds, and movies, SMS data composed of various letters, and a variety of data referred to by filtering units of the message discriminating section.

The subscriber DB 15 stores the telephone numbers of mobile-communication terminals, the names of mobile-communication service subscribers, SMS or MMS automatic insertion options, and the terminal information of the mobile-communication terminals (the terminal information of mobile-communication terminals transmitting and receiving a short message) (for example, whether or not to support the MMS service, information on terminal display specification and the like).

Through the personal information (for example, the telephone number of a mobile-communication terminal, whether a subscriber has joined the message conversion service, and a subscriber ID and password) of a mobile-communication subscriber stored in the subscriber DB 15, the subscriber authentication section 21 checks whether the mobile-communication subscriber has joined the message conversion service or not. Further, the subscriber authentication section 21 verifies setting items related to the message conversion service, which are stored in the subscriber DB 15, and the terminal information of a destination mobile-communication terminal receiving an SMS or MMS message. Then, the subscriber authentication section 21 provides the corresponding sections with information required for the message conversion.

When the SMS center or MMS center 12 receives a message from a mobile-communication terminal, and if a corresponding mobile-communication subscriber has joined the message conversion service, the SMS center or MMS center 12 requests the message conversion system 13 to convert the message into an SMS or MMS message. Meanwhile, if the mobile-communication subscriber has not joined the message conversion service, the message is transmitted to a mobile-communication terminal through a conventional manner.

The message discriminating section 22 serves to perform pre-processing of message conversion as follows. The pre-processing of the message discriminating section 22 includes verifying the terminal information of a destination communication terminal receiving a message and the setting item related to the message conversion service when the message is received from a subscriber terminal; and grasping the meaning structure of context through first to third filtering units. The first filtering unit uses a plurality of sentences for one subject, each sentence being composed of one or more letters. The second filtering unit uses a sentence composed of one or more words including replaceable word. The third filtering unit accumulates transmitted message contents through the grasped context so as to extract repeatedly used phrases or sentences and expressions, the third filtering unit being an individualization unit using a statistical method.

The individualization unit 28 using a statistical method analyzes a message for each user, extracts a repeatedly used phrase for the frequency, produces or assigns contents on the repeatedly-used phrase, and applies the service.

The component extracting section 23 extracts MMS data or SMS data corresponding to the subscriber message from the component/filtering DB when the subscriber message passes through the filtering section via the message discriminating unit. Depending on the display specification of the destination mobile-communication terminal, the component combining section 24 combines the subscriber message with the MMS data or SMS data or substitutes the received message with the MMS data or SMS data, thereby creating an MMS or SMS message.

The Internet matching section 26 is connected to a mobile-communication terminal and/or the computer 16 through the Internet and provides a message conversion service subscription web page, a web page for writing a message, a web page for various environment settings related to the message conversion, and an SMS or MMS setting/inquiring web page.

Meanwhile, it will be easily understood by a person with an ordinary skill in the art that the message, written on the web page of the Internet matching section 26 by a mobile communication subscriber, is processed in the same manner by the respective sections, as described above. Additionally, in accordance with the request of a subscriber, the mobile communication terminal can be informed that the message conversion is normally performed.

Further, the message conversion service can be charged by a monthly flat rate or can be charged based on the number of transmitted SMS messages or the number of transmitted MMS messages.

Fig. 5 is a diagram of the filtering section of the message conversion system according to the invention. As shown in Fig. 5, the filtering section includes a first filtering unit using a plurality of phrases and clauses, a second filtering unit using the structure of phrase and clause, and a third filtering unit serving as an individualization unit using a statistical method.

Specifically, when a word to be recognized through the simple word recognition is set as one subject, the first filtering unit sets a plurality of phrases and clauses in which the word or the meaning thereof is used. For example, it is assumed that a subject such as 'bus' is set and the simple word recognition is used. In this case, if a message saying 'I am walking because I don't want to get on a bus' is decorated with a picture in which people go by bus, this can be an error. Here, clearer filters composed of one or more words, such as 'going by bus', 'in a bus', and 'I will take a bus', are used. This is because the plurality of filters should be used in one subject in order to increase the frequency of recognition.

The second filtering unit uses filters composed of one or more words, of which portions can be replaced in order to increase the frequency of recognition. For example, when a filter such as 'A, I love you' on a subject such as 'love' is used, A corresponds to 'sweet heart' or a specific name. As another example, when a filter such as 'A and B fought with each other' on a subject such as 'fight' is used, A and B can correspond to names of many and unspecified persons. Filters using phrases and clauses including such replaceable words can be constructed to be more complicated than the above-described examples. Further, although the overall words do not coincide, the recognition can be performed, thereby making up for a low recognition rate of the filters composed of phrases and clauses.

Although the first and second filtering units use one or more words in order to reduce an error, the recognition rate thereof can decrease, compared with the simple word recognition. The third filtering unit can make up for this by using the individualization using a statistical method. The individualization using a statistical method is where transmitted message contents of private users are accumulated so that repeatedly used phrases or sentences and expressions are automatically extracted in order to provide message conversion corresponding thereto. Under the assumption that words and expressions frequently used by users are highly likely to be reused, the individualization has an effect of increasing a recognition and service provision success rate of user message. The individualization using a statistical method is roughly divided into a step of analyzing a message for each user, a step of extracting a repeatedly used phrase for a frequency, a step of producing or assigning contents on the repeatedly used phrase, and a step of applying the service. The steps of analyzing a message for each user and extracting a repeatedly used phrase for a frequency are performed by an automated program, and the steps of producing or assigning contents on the repeatedly used phrase and applying the service are stored in a CMS DB through the operation of a manager.

Fig. 6 is a diagram showing a flow of a statistical processing system according to the invention, and Fig. 12 is a flow chart of a statistical processing method according to the invention, hi the above-described word recognition method, one or more words are used in order to reduce an error. However, a recognition rate can decrease compared with the simple word recognition. In this case, the individualization using a statistical method can make up for such a defect. The individualization using a statistical method is where transmitted message contents of private users are accumulated so that repeatedly used phrases or sentences and expressions are automatically extracted in order to provide message conversion corresponding thereto. Under the assumption that words and expressions frequently used by users are highly likely to be reused, the individualization has an effect of increasing a recognition and service provision success rate of user message. The individualization using a statistical method is roughly divided into a step of analyzing a message for each user, a step of extracting a repeatedly used phrase for a frequency, a step of producing or assigning contents on the repeatedly used phrase, and a step of applying the service. The steps of analyzing a message for each user and extracting a repeatedly used phrase for a frequency are performed by an automated program, and the steps of producing or assigning contents on the repeatedly used phrase and applying the service are performed by the operation of a manager. Figs. 7 to 10 are diagrams illustrating memory mapped I/O according to the invention.

The above-described filtering units perform much more complicated processing than the simple word recognition. Therefore, when the filtering units are implemented in a general manner, a high level of operation ability is needed. Accordingly, the memory mapped I/O for increasing a rate is implemented for efficiency. In order to check the context or words of a user message so as to attach suitable components, a list of contents and a list of words/phrases are necessary, and mapped information between the corresponding lists is necessary. Typically, such data are usually managed by using a DB in which addition/delete/update are easily performed. In the service in which contents suitable for a context are attached, the contents and data of words/phrases should be constantly added and updated through the feedback of users, in order to increase the satisfaction degree of customers. Therefore, the ease of contents management should be considered to be important, in order to implement the service.

When a DB is used, a management function of adding/deleting/updating contents and data of words/phrases can be implemented by a simple SQL sentence. As described above, the contents management module is easily implemented. However, if a module (hereinafter, referred to as 'contents usage module') for attaching contents to a text message by using such data must access the DB whenever selecting the contents, the rate of the contents usage module decreases. Since it generally takes hundreds of msecs to access a DB, such a DB access is not appropriate for the contents usage module which should process more than one hundred text messages per a second. This method is shown in Fig. 7.

In the method shown in Fig. 7, the contents management module directly updates the DB, and the contents usage module directly reads data from the DB so as to guarantee the identity of the contents, the word/phrase data, and the relational data. Although the rate is low, the contents management module and the contents usage module respectively access the DB regardless of the states of the modules. Therefore, the implementation process is simple.

In order to prevent the contents usage module from using a DB while the DB is used, the following method is used. When the contents usage module is driven, the contents usage module is connected to the DB so as to load all data into a memory. Then, whenever the contents are selected, the data of the memory is used. Even in this method, however, whenever the contents or word/phrase data are updated, the contents usage module should be connected to the DB so as to update the data loaded in the memory. Therefore, performance degradation inevitably occurs whenever the data is updated. This method is shown in Fig. 8.

The present invention proposes a method in which while the contents management module uses a DB such that the ease of managing contents and data of words/phrases is maintained, the contents usage module uses the latest contents and word/phrase data so as to maintain the maximum performance without using the DB. In the invention, the memory mapped I/O technique is used for the method. The memory mapped I/O technique is where the entire portion or portions of a file is or are mapped in a memory so as to be used. When a mapped memory region is read, data identical to the data file can be read. That is, when the contents management module updates the data file, the mapped memory region of the contents usage module is simultaneously updated. Therefore, in this method, the contents usage module can instantly recognize the update of data required for the service, such as the contents and words/phrases, without a separate operation. The method using this technique is shown in Fig. 9.

In the memory mapped I/O, a memory is not directly accessed, but a file is accessed at an enhanced rate. The data read/write rate through the memory mapped I/O is three times higher than when a file is read/written, which means the rate through the memory mapped I/O is lower than when a memory is directly accessed. Therefore, the technique shown in Fig. 9 is lower in a service performance rate than the technique shown in Fig. 10. In Fig. 8, when the contents usage module is initialized, all contents and data of words/phrases should be loaded in the memory, in order to maintain a high rate. Therefore, when the amount of contents and word/phrase data is larger than the capacity of the memory, the technique shown in Fig. 8 cannot be used. However, the memory mapped I/O can be utilized even in this case, because only data which are actually used can be mapped in the memory. hi the invention, the technique of Fig. 9 is implemented in a system including a memory which cannot store all contents and data of words/phrases, and the technique of Fig. 10 is implemented in a system including a memory which can store all contents and data of words/phrases.

A method shown in Fig. 10 is obtained by combining the technique of Fig. 8 and the technique of Fig. 9. In the method, the contents usage module loads all contents and data of words/phrases into a memory at the time of initialization, and simultaneously, mapping is performed by using the memory mapped I/O. Then, when data is used during the service, the data is read only from the memory. Therefore, the contents usage module can show the best performance. In this case, the contents usage module periodically checks a field of whether contents are updated or not in the mapped region. Since the field requires only one byte, accessing one time per second does not have an effect on the performance.

When the contents and data of words/phrases are updated, the contents management module reflects the updated contents and data into the DB and the data file and sets the field of whether contents are updated or not. At this time, the contents usage module detects the update of the contents and data of words/phrases and copies the data of the mapped region into the memory.

Fig. 11 is a flow chart of the message conversion method according to the invention. As shown in Fig. 11, a message is received (SI l), and subscriber information and terminal information of a destination terminal are checked (S 120). Then, it is judged whether the subscriber has joined the message conversion service or not (S 13). If the subscriber has joined the message conversion service, it is checked whether the message passes through the filtering section or not (S 14). If the message passes through the filtering section, components suitable for the subscriber message are extracted (S 15) so as to be combined with the subscriber message (S 16). The message combined with the components is transmitted through the message transmitting section.

Figs. 13 and 14 are diagrams showing examples of messages to which the invention is applied. Fig. 13 shows an example of a message which is combined with picture components, and Fig. 14 shows an example of a message which is combined with moving image and picture components.
