To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. The following terms are defined in consideration of the functions in the embodiments of the present invention, which may vary depending on the intention of the user, the intention or the custom of the operator. Therefore, the definition should be based on the contents throughout this specification.

FIG. 1 is a diagram illustrating a configuration of a content service system including an apparatus for providing an artificial intelligence platform according to an embodiment of the present invention. Referring to FIG. The artificial intelligence platform providing apparatus 100 of FIG. 1 is interlocked with a plurality of contents service servers 300 for providing contents to a user terminal 200 and is provided with a non-typical The user's request through the input can be processed. That is, the artificial intelligence platform providing apparatus 100 may transmit the content desired by the user to the user terminal 200 from the content service server 300 in response to the request, and provide the user with the content.

When the user desires to receive information (e.g., the distance from the current location to the Namdaemun and the expected time) from the content service server 300 through the user terminal 200, Instead of the conventional way of touching the screen and providing the desired answer visually, you may want to ask questions through your own voice as if you are talking to someone else, and you might want to be provided with answers in the form of voices. The artificial intelligence platform providing apparatus 100 according to an embodiment of the present invention can perform a function of providing artificial intelligence services to the user.

The user terminal 200 may receive the information input by the user and transmit the received information to the artificial intelligence platform providing apparatus 100 or the content service server 300 or may transmit the information from the artificial intelligence platform providing apparatus 100 or the content service server 300 And to provide the received content to the user. The user terminal 200 may be any terminal that can be used by a general user for personal use. Preferably, the user terminal 200 may include a wireless communication device, such as a smart phone, a PCS (Personal Digital Assistant), a PDA (Personal Digital Assistant), an IMT (International Mobile Telecommunication) -2000, a CDMA (Code Division Multiple Access-2000, W-CDMA (WCode Division Multiple Access), Wibro (Wireless Broadband Internet) terminals, and the like.

The content service server 300 may provide the content requested by the user to the user terminal 200 directly or through the artificial intelligence platform providing apparatus 100. [ The content service server 300 can provide, for example, music, moving picture, navigation service, and the like, but the present invention is not limited thereto. The data server 200 may be implemented by a computer such as a PC (Personal Computer) or a workstation.

2 is a block diagram of an apparatus for providing an artificial intelligence platform according to an embodiment of the present invention. 2 may include an interface unit 110, a control unit 120, a communication unit 130, a content processing unit 140, an authentication unit 150, and a database 160 . However, since the components of the artificial intelligent platform providing apparatus 100 of FIG. 2 and the detailed configurations of the respective components to be described below and the connection relationships between the respective components are merely one embodiment of the present invention, The technical idea of the present invention is not limitedly interpreted.

The interface unit 110 may receive input data of a predetermined format from the user terminal 200. [ Such input data may include a user's content provision request. The format of the input data may be, for example, voice or gesture. When the user desires to listen to music, the user terminal 200 can say "Play YY of XX Singer ". In this case, the format of the input data may be voice data. Alternatively, the user may take a gesture that the user terminal 200 spreads three fingers to select option 3 when presenting the selection options 1 through 5 through the display, in which case the format of the input data Will be the gesture data.

The user terminal 200 may receive input data having a format such as voice or gesture through a microphone or a camera but may not have a function for interpreting such input data. At this time, the user terminal 200 may transmit the received input data to the artificial intelligence platform providing apparatus 100. The interface unit 110 may receive such input data, and accordingly, the interface unit 110 may include a wired or wireless communication module for receiving input data such as audio data containing voice or image data containing a gesture can do.

The control unit 120 can extract the request information included in the input data received by the interface unit 110. For example, the control unit 120 extracts the request information from the audio data containing "Play YY of XX Singer ", which means that the user desires to hear the song YY of XX Singer.

After extracting the request information, the controller 120 selects one or more of the plurality of content service servers 300 interlocked with the artificial intelligence platform providing apparatus 100 based on the extracted request information, and responds to the request information To the content service server 300 that has been selected to provide the content to the user terminal 200.

In the above example, the user may select the content service server 300 providing the sound source service among the linked content service servers 300 by the control unit 120. If two or more contents service servers 300 providing the sound source service are interworked, the controller 120 controls the contents server 300 based on input data from the user terminal 200, Can be selected.

When the user selects reproduction of the song YY of the XX syllable number through the user terminal 200 using a typical input means such as a touch, the control unit 120 transmits the song YY from the user terminal 200 to the content service server 300 It is possible to combine the commands that are expected to be transmitted. Since the format of such an instruction may be different for each content service server 300, the database 160, which will be described later, stores a command synthesis method for each content service server 300 linked to the AI platform providing apparatus 100 .

The communication unit 130 can perform data transmission / reception with the content service server 300 under the control of the control unit 120. [ The command synthesized by the controller 120 may be transmitted to the content service server 300 through the communication unit 130. The content provided by the content service server 300 in response to the command may also be transmitted through the communication unit 130 Lt; / RTI > The communication unit 130 may be implemented through a wired or wireless communication module.

The content processing unit 140 may convert the format of the content received from the content service server 300 through the communication unit 130. [ The format conversion of the content may be performed when the format of the received content corresponds to a conversion required format matching the format of the input data.

The format conversion of the above-described contents will be described below as an example. The content service server 300 receives the command synthesized by the control unit 120 that has entered the voice data 'Tell the height of Baekdu mountain' to the user terminal 200 and extracts the request information from the input voice data. Assume that a content including information of "2,744 meters in height " is transmitted to the communication unit 130. At this time, since the user asks the user through the voice as if he or she is asking the person, the answer should also be heard through the voice so that it feels as if the natural artificial intelligence service is provided.

Accordingly, the content processing unit 140 can convert the content of the text format into audio data having the same format as the input data. That is, in this case, the conversion required format matched with the format of the audio data may be the format of the text data, and if the input data has the format of the audio data, the content having the format of the text data will be converted into the format of the audio data .

Alternatively, in the case of image data, it may be set not to be a conversion required format matched to the input data. At this time, the content processing unit 140 may not perform the format conversion of the content even if the content of the image data is received from the content service server 300 through the communication unit 130. [ However, even if the format is not converted enough, the content processing unit 140 may appropriately process the content for the user of the user terminal 200. [ The content processing unit 140 may be realized by a computing device including a microprocessor together with the control unit 120 and the authentication unit 150 described later.

As described above, when the contents are converted by the contents processing unit 140, the converted contents can be transmitted to the user terminal 200 by the interface unit 110 and provided to the user.

The authentication unit 150 may perform authentication for the user terminal 200 that intends to use the artificial intelligence platform providing apparatus 100. [ In some cases, the content service server 300 may adopt a policy that allows only the authenticated user terminal 200 to use the content through member registration or the like. If the artificial intelligence platform providing apparatus 100 extracts the request information from all the input data from the user terminal 200 and transmits an instruction corresponding to the extracted request information to the contents service server 300, 300). However, the fact that the artificial intelligence platform providing apparatus 100 performs authentication with all of the data necessary for authentication of a large number of contents service servers 300 also has various difficulties such as a problem related to realistic implementation and protection of personal information .

In response to the request from the content service server 300, the authentication unit 150 issues a token for authentication of the specific user terminal 200 to the content service server 300 that has transmitted the request . That is, the authentication unit 150 allows the content service server 300 to perform the actual authentication process, and when the content service server 300 requests the token for the authenticated user terminal 200, the authentication unit 150 transmits the corresponding user terminal 200 You only need to issue a token for.

The content service server 300 that has received the token may deliver the issued token to the user terminal 200. The user terminal 200 may transmit the token together with the input data to the artificial intelligence platform providing apparatus 100 . The authentication unit 150 can check the validity of the received token when the token is received and can control the interface unit 110 so that only the input data transmitted together with the token determined as a legitimate token can be input and processed have.

The above-described validity check of the token can be performed based on the issuance token information stored in the database 160. [ When the user terminal 200 transmits a token, the authentication unit 150 transmits the token to the authentication unit 150. When the user terminal 200 transmits the token to the authentication unit 150, Whether the valid token is valid for the user terminal 200, or the like can be determined using the issued token information.

Through the above-described series of operations performed by the authentication unit 150, the artificial intelligent platform providing apparatus 100 can perform authentication for the user terminal 200 in a simple and effective manner.

The database 160 may store information required by the artificial intelligence platform providing apparatus 100. Examples of such necessary information include types of conversion required formats matched to the format of specific input data, types of commands for each content service server 300, issuance token information about tokens issued by the authentication unit 150, and the like . Of course, the information stored in the database 160 is not limited to the above example, and may be any information required for operation of the artificial intelligence platform providing apparatus 100.

The database 160 may be embodied as a computer readable recording medium. Examples of such computer readable media include magnetic media such as hard disks, floppy disks and magnetic tape, optical media such as CD-ROMs, DVDs, A magneto-optical media such as a floppy disk, a magneto-optical media such as a floppy disk, a magneto-optical media such as a floppy disk, a magneto-optical media such as a floppy disk, a magneto-optical media such as a floppy disk, a flash memory, .

FIG. 3 is a view for explaining a specific embodiment of an artificial intelligence platform providing apparatus according to an embodiment of the present invention. 3 is a diagram for explaining a case where a user of the user terminal 200 requests content using his or her voice on the assumption that the format of the input data is audio data. Is not intended to be limited to audio data. It should be noted that some of the configurations shown in FIG. 2 are omitted in FIG. 3.

The user terminal 200 can transmit the input data to the artificial intelligence platform providing apparatus 100 by inputting the input data of "Tell the height of Baekdu mountain" to the user terminal 200 through the user's own voice. The input data may be transmitted to the control unit 120 through the communication unit 110 (1 in Fig. 3).

The control unit 120 may include an automatic speech recognition (ASR) unit 121 and a natural language processing unit (NLU) 122. The voice recognition unit 121 can convert the voice input data of "Tell the height of Baekdusan" to the text data of the same content (② in FIG. 3). The natural language processing unit 122 can interpret the text data of "tell the height of Baekdu mountain" by morphemes and interpret the text data to mean that the user wants to know the "height" .

That is, by the operation of the speech recognition unit 121 and the natural language processing unit 122, request information including keywords such as " Baekdu Mountain, "" height ", " Can be extracted. The synthesized command may be transmitted to the selected content service server 300 through the communication unit 130. The synthesized command may be transmitted to the selected content service server 300 through the communication unit 130. [ (Fig. 3 ③).

The content processing unit 140 may include a natural language generating unit (NLG) 141 and a text-to-speech unit (TTS) 142. 3), the natural language generating unit 141 converts the received data into a natural sentence from the content service server 300. The natural language generating unit 141 converts the received data into a natural sentence Thus, the text data "the height of Mt. Baekdu is 2,744 meters" can be generated (⑤ in FIG. 3). The voice-to-speech converting unit 142 can convert the text data into voice data, whereby the height of Baekdu Mountain is 2,744 meters. The voice response is provided to the user through the interface unit 110 via the user terminal 200 (Fig. 3 ⑥).

4 is a flowchart illustrating a content service method according to an exemplary embodiment of the present invention. The method may be performed using the artificial intelligence platform providing apparatus 100 described with reference to Figs. However, since the method of FIG. 4 is only an embodiment of the present invention, the concept of the present invention is not limited to FIG. 4, and each step of the method of FIG. Of course.

First, the content service server 300 can perform authentication for the user terminal 200 (S101). This authentication procedure may be a function of the content service server 300, which is independent of the artificial intelligence platform providing apparatus 100 in principle.

Next, the content service server 300 may request the artificial intelligence platform providing apparatus 100 to issue a token for the authenticated user terminal 200 (S102). The artificial intelligence platform providing apparatus 100 may issue a token for the user terminal 200 and transmit the token to the contents service server 300 in operation S103. The contents service server 300 transmits the token to the user terminal 200 ). Such a token may be a means for the artificial intelligence platform providing apparatus 100 to identify and authenticate the user terminal 200. The user terminal 200 can establish a session with the artificial intelligent platform providing apparatus 100 to receive a PUSH response from the artificial intelligence platform providing apparatus 100 using the token ).

When the user terminal 200 transmits the input data to the artificial intelligence platform providing apparatus 100 (S106), the artificial intelligence platform providing apparatus 100 transmits the input data to the user terminal 200 using the token transmitted together with the input data (S107). If the user terminal 200 passes the authentication, the artificial intelligence platform providing apparatus 100 can receive and process the input data (S108).

Specifically, the artificial intelligence platform providing apparatus 100 extracts user's request information from the input data (S109), selects the content service server 300 based on the request information (S110) After combining the commands (S111), the synthesized command may be transmitted to the selected content service server 300 (S112).

The content service server 300 may transmit the content corresponding to the command to the artificial intelligence platform providing apparatus 100 (S113). Then, the artificial intelligence platform providing apparatus 100 can perform processing such as converting the format of the received content (S114) and transmit the processed contents to the user terminal 200 (S115).

Through the above-described process, the user can conveniently receive the artificial intelligence service using the user terminal 200. Such an artificial intelligence service has an advantage that it can be implemented without making major changes to the existing user terminal 200 or the content service server 300.
