The learning information manager 202 determines a learning progress state of the user and updates the learning progress state of the user in the learning information database when the learning of the user is completed. The learning information manager 202 confirms the user by using the user identification information, and checks the learning progress database corresponding to the user by checking the learning information database. At this time, the learning information management unit 202 checks whether there is a skipped course after completing the specific unit learning.

In addition, the learning information management unit 202 manages the learning state that the user progresses online through in conjunction with the course manager, and records the completed unit learning information and the skipped course information in the learning information database when the learning is completed.

The terminal profile determiner 204 determines the user terminal profile by using the terminal identification information and the terminal profile information received from the user terminal 150.

When receiving the terminal profile information from the user terminal 150, the terminal profile determination unit 204 determines the profile of the received terminal and registers the profile as the terminal information of the user in the terminal profile database.

The terminal profile determining unit 204 receives only terminal header information from the user terminal when the profile information of the specific terminal of the user is stored in the terminal profile database, and receives the terminal profile of the user without receiving profile information from the user terminal through the header information. Judge.

The learning information management unit 202 and the terminal profile determination unit provide the learning progress state information and the terminal profile information of the user to the content selection unit 206, and the content selection unit 206 corresponds to the learning progress state and the terminal profile of the user. Select the content.

The content selection unit 206 first selects a content set corresponding to the provided learning progress state. As described above, the content management apparatus stores a plurality of contents having various content profiles for a specific unit learning, and the content selection unit 206 generates a plurality of content sets corresponding to the unit learning to be learned by the user. Choose.

The content selection unit 206 selects a content corresponding to the user terminal profile among a plurality of contents corresponding to the specific unit learning. As described above, a content profile is set for each content, and the content suitable for the user terminal is selected using the terminal profile and the content profile information.

3 is a block diagram illustrating a module configuration of a content selection unit according to an exemplary embodiment of the present invention.

Referring to FIG. 3, the content selection unit according to an embodiment of the present invention may include an analysis unit 300, a content set selection unit 302, an operation unit 304, and a selection unit 308.

The analysis unit 300 determines the unit learning to be learned by the user using the learning progress state information, and checks the attributes and attribute values of the terminal using the terminal profile information.

The content set selector 302 selects a content set corresponding to the learning progress state of the user. The content set selector 302 checks the learning progress state from the analyzer 300 and selects a content set corresponding to the unit learning to be progressed by the user.

The calculator 304 calculates the content suitability using the terminal profile and the content profile of the contents included in the content set selected by the content set selector 302.

According to a preferred embodiment of the present invention, the attributes of the terminal profile can be broadly classified into two types, one of which is a continuous attribute of which attribute values are continuous, and the other of which is a discrete attribute whose attribute values are discrete. In this case, the continuous attribute may have an arbitrary value of 0 or more and 1 or less, and the discrete attribute may have a value of either 0 or 1.

Among the above-mentioned attributes, the size of the learning content (FileSize) and the size of the display (ScreenSize) are examples of continuous attributes, and the type of audio channel (AudioChannel) and whether the terminal supports sound output (SoundOutputCapable) are examples of discrete attributes. to be.

In addition, the continuous attribute and the discrete attribute may each be subdivided into two kinds of sub-attributes. That is, the continuous attribute is subdivided into a one-dimensional continuous attribute with one variable representing the attribute and a two-dimensional continuous attribute with two variables representing the attribute, and the discrete attribute may have a goodness of fit for the learning content with one attribute value. A single discrete attribute, and the learning content may have goodness of fit for two or more attribute values.

Among the above-mentioned attributes, since the size of the learning content (FileSize) is represented by one variable, it corresponds to a one-dimensional continuous attribute, and the size of the display is represented by two variables (horizontal size and vertical size). Corresponds to a continuous attribute. In addition, whether the terminal supports sound output (SoundOutputCapable) can be applied to only one of Yes (Fitness = 1) or Disable (No, Goodness = 0), so that the terminal corresponds to a single discrete property, and the type of the audio channel (AudioChannel) is Depending on the type of learning content, only one channel can be supported (for example, only mono), and some channels can be supported (for example, mono, stereo, 2.1 channel, and 5.1 channel). This corresponds to multiple discrete attributes. The calculator 123 calculates a goodness of fit of the plurality of learning contents with respect to the attribute value of the attribute of the terminal. Here, the plurality of learning contents refers to candidate learning contents that can be provided to the terminal 150, and the suitability indicates how appropriate the learning contents are for each of the plurality of learning contents with respect to the attribute values of the attributes of the terminal 150. Means a measure to indicate. At this time, the goodness of fit has any real value between 0 and 1.

According to an embodiment of the present invention, the calculating unit 302 may calculate a goodness of fit of the attributes and attribute values of the content profile and the attributes and attribute values of the terminal profile.

For example, the information on the goodness of fit of the learning content is expressed as shown in the graph shown in FIGS. 5 to 8, and the calculation unit 302 corresponds to the goodness of fit (attribute value) of the attribute value (horizontal axis value) of the attribute of the terminal 150 in the graph. By finding the vertical axis value, the fitness of the plurality of contents with respect to the attribute value of the attribute of the terminal 150 can be calculated. In this case, the graph shown in FIG. 5 is a goodness-of-fit graph for the size of the learning content (FileSize), the graph shown in FIG. 6 is a goodness-of-fit graph for the size of the display (ScreenSize), and FIG. 7 is a terminal 150. Goodness information information graph for whether or not the sound output support (SoundOutputCapable), Figure 8 is a fitness information graph for the type (AudioChannel) of the audio channel.

The selector 304 selects one content to be provided to the terminal 150 from among the plurality of contents based on the goodness of fit of the plurality of learning contents calculated on the attribute value of the attribute of the terminal 150.

That is, as described above, since the learning content becomes more suitable for the terminal 150 as the fitness value is larger, the selector 304 selects one learning content to be provided to the terminal 150 using the learning content.

According to an embodiment of the present invention, when there are a plurality of attributes and attribute values of the terminal 150, the selecting unit 124 may select a terminal (based on an average value of the goodness of fit of the plurality of learning contents with respect to the attribute values of the plurality of attributes). 150 may select learning content to be provided. This may be expressed as Equation 1 below.

는 적합도의 평균값, x는 학습 컨텐츠, n은 속성의 개수이고,

는 I번째 속성의 속성값에 대한 적합도를 각각 의미한다. here,

Is the mean value of goodness of fit, x is the learning content, n is the number of attributes,

Denotes goodness of fit for the attribute value of the I-th attribute.

In this case, according to an embodiment of the present invention, the selector 304 may select the learning content having the maximum average value of fitness as the learning content to be provided to the terminal 150.

At this time, if there are two or more learning contents having a maximum average value of fitness, the selection unit 304 learns to be provided to the terminal 150 among the two or more learning contents based on the characteristic information of the user of the terminal 150. You can select content.

For example, if there are two learning contents (image content and video content) having an average value of goodness of fit, and the selection unit 304 knows that the user prefers the video content to the image content, the selection unit 304 may The video content may be selected as learning content to be provided to the terminal 150. At this time, the characteristic information of the user becomes the content preference of the user.

In another example, two learning content items with a maximum mean value of goodness of fit (text content 1 with black text written on a white background and text content 2 written with red text on a blue background) indicate that the user has a history of epilepsy. If the selection unit 304 knows, due to the fact that the text content 2 has a high probability of seizure, the selection unit 304 may select the text content 2 as the learning content to be provided to the terminal 150. At this time, the characteristic information of the user becomes the accessibility of the user.

On the other hand, according to another embodiment of the present invention, when there are a plurality of attributes and attribute values of the terminal 150, the selector 304 suitability and a plurality of attributes of the plurality of learning content for the attribute values of the plurality of attributes The content to be provided to the terminal 150 may be selected based on the average value of the product of multiplying the predetermined weights corresponding to. This may be expressed as Equation 2 below.

는 복수의 속성 및 이와 대응되는 가증치를 각각 곱한 값의 평균값을 의미하고,

는

와 대응되는 가중치를 의미한다. 이 경우, 선택부(304)는 복수의 속성 및 이와 대응되는 가중치를 각각 곱한 값의 평균값이 최대인 학습 컨텐츠를 단말기(150)에 제공할 학습 컨텐츠로 선택할 수 있다.here,

Means an average value of a product of a plurality of attributes and their corresponding increments,

Is

Means a weight corresponding to. In this case, the selector 304 may select, as the learning content to be provided to the terminal 150, the learning content having the maximum average value of the product of the plurality of attributes and the weight corresponding thereto.

로 설정하여 해당 학습 컨텐츠를 선택에서 제외시킬 수 있다. 일례로, 학습 컨텐츠가 플래시(flash) 컨텐츠인 경우, 단말기(150)에 플래시 플레이어(flash player)가 존재하지 않는다면, 플래시 컨텐츠 자체가 재생될 수 없으므로, 이러한 경우, 선택부(124)는 단말기(150)의 속성에 대응되는 가중치 값을

로 설정할 수 있다. The weight is for providing optimal learning content to the terminal 150. In general, the weight may be determined experimentally within a range of greater than 0 and greater than 1. At this time, if the attributes of the terminal 150 and the attributes of the learning content do not exactly match, there may be a case in which the reproduction of the learning content is impossible in the terminal 150. In this case, the selection unit 304 may determine a weight value.

Set to to exclude the learning content from the selection. For example, when the learning content is flash content, if a flash player does not exist in the terminal 150, the flash content itself cannot be played. In this case, the selection unit 124 may use the terminal ( Weight value corresponding to the property of 150).

Can be set to

In addition, if there are two or more learning contents whose average value of the product of multiplying the plurality of attributes and their corresponding weights is the maximum, as described above, the selector 304 is based on the characteristic information of the user of the terminal 150. By selecting the learning content to be provided to the terminal 150 from the two or more learning content.

Figure 4 is a flow chart showing the overall flow of the online training method in consideration of the user learning progress state according to an embodiment of the present invention.

Referring to Fig. 4, first, the user terminal accesses the educational system of the present invention (step 400).

When the user terminal is connected, the profile and the user identification information of the connected user terminal are determined (step 402).

If the user terminal is a registered terminal, the terminal profile may be determined only by the header information of the terminal. If the user terminal is not a registered terminal, the terminal profile information is received from the user terminal.

Using the user identification information received from the user terminal, it is determined whether there is a skipped course in the unit learning that the user has already performed (step 404). As described above, the course manager manages course information progressed by the user when the user progresses learning, and if there is a skipped course, it is recorded in the learner information database.

If there is a skipped course through the information in the learner information database, the unit learning content including the skipped course is checked (step 406). In this case, the unit learning content including the skip course may be plural.

If the unit learning content including the skipped course is confirmed, it is determined whether the user terminal can support the content (step 408). It is determined whether there is content that can be supported by the user terminal among a plurality of unit learning contents including a skip course.

If the user terminal can support one of the unit learning contents including the skip course, the corresponding content is transmitted to the user terminal (step 410). In this case, it is preferable to transmit only skipped courses among the unit learning contents to the user terminal.

If the skipped course does not exist or the skipped course is provided to the user terminal, the learning progress state of the user is checked (step 412). Based on the information stored in the learner information database, the unit learning information to be progressed by the user is identified.

로 설정하여 적합도를 연산한다. When the unit learning information to be progressed by the user is identified, the most suitable content for the user terminal is selected among the contents corresponding to the unit learning (step 414). As described above, the fitness is calculated by using the attributes and attribute values of the terminal profile and the attributes and attribute values of the content profile, and discrete and continuous attributes are divided and calculated during the fitness calculation. In addition, for attributes that must be absolutely supported,

Set to to calculate the goodness of fit.

When the content suitable for the user terminal is selected, the content is transmitted to the user (step 416). The course that the user learns when the content is transmitted is managed by the course manager, and if there is a course that is skipped due to the characteristics of the content, the course manager manages the skipped course information.

When the learning of the user is finished, the learning progress state of the user of the learning information database is updated (step 418).

Although the above has been described with reference to embodiments of the present invention, those skilled in the art may variously modify the present invention without departing from the spirit and scope of the present invention as set forth in the claims below. And can be changed.
