Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram illustrating an apparatus for providing contents according to a preference according to an exemplary embodiment of the present invention. An apparatus for providing contents according to a preference (hereinafter, referred to as a content providing apparatus) 200 is a transceiver 210. , A storage 220, a controller 230, a pattern analyzer 240, a list extractor 250, and a similarity calculator 260.

The storage unit 220 stores a content list registered by a user who wants to register a content list (hereinafter, referred to as a registered user). The contents included in the contents list include multimedia contents, still image contents, and moving image contents as multimedia contents.

Here, the registered user may register a series of contents lists which the user prefers. Hereinafter, the series of contents list is called an album. That is, the registered user may register a specific set of the content list to be registered as one album, and may register another album by the same process.

Therefore, one album may include a list of one or a plurality of contents.

One album may include a list of various types of content. Here, the type may be based on the classification of the multimedia, it may be based on the classification according to the nature of the content itself.

For example, an album containing various kinds of contents according to the classification of multimedia may include audio content, still image contents, and video contents, and an album containing various kinds of contents by classification according to the nature of the content itself may be included in the album. Audio content of various rhythms, still images of various moods, or videos of various genres may be included.

In particular, in the case of audio content, a separate classification method may be used as a kind as well as a rhythm. For example, audio content according to genre, age group, time, feeling, weather, or situation may be included in one album.

Hereinafter, the present invention will be described based on audio contents, but this is only one example, and still image contents and video contents are included in the scope of the present invention.

The number of types may vary depending on whether the content providing apparatus 200 is implemented or may be set by a registered user.

In addition, the storage unit 220 may store the content included in the content list. Accordingly, a user searching for an album (hereinafter referred to as a search user) may access the corresponding content through the content list.

The search user may separately input a favorite content list through a predetermined terminal to compare the pattern (hereinafter referred to as the second pattern) with the pattern of the registered registered user (hereinafter referred to as the first pattern). It is also possible to compare the pattern for the content list that is previously input as the registered user with the first pattern stored by the other registered user.

Therefore, the storage unit 220 may store both the content list corresponding to the first pattern and the second pattern.

The storage unit 220 may include a hard disk, a flash memory, a compact flash card (CF), a secure digital card (SD), a smart card (SM), a multimedia card, a memory stick, a memory stick, or the like. As a module capable of inputting / outputting information, the module may be provided inside the apparatus or may be provided in a separate apparatus.

The pattern analyzer 240 analyzes the first pattern of the ratio of the quantity of each content list included in the album created by the registered user and the second pattern of the ratio of the quantity of each content list input by the search user. It plays a role.

Here, the pattern analyzer 240 may analyze the first pattern when the content list is registered by the registered user, and analyze the second pattern when the content list is input by the search user, and the content by the search user. When the list is input, the first pattern and the second pattern may be analyzed.

When the first pattern is analyzed when the content list is registered by the registered user, the result thereof may be stored in the storage unit 220 corresponding to the album including the corresponding content list.

Here, the registered user may store a plurality of albums in the storage unit 220 in correspondence with the first pattern, and store each album in correspondence with the first pattern, and store the entire album in the first pattern. You can also match them. Accordingly, the search user may search for the specific album of the registered user, or search the entire album of the registered user.

The pattern analyzer 240 may analyze the first pattern and the second pattern using at least one of the increase / decrease pattern with respect to the ratio, the slope of the increase / decrease pattern, and the increase / decrease pattern of the gradient.

A detailed description of the pattern analysis of the pattern analyzer 240 will be described later with reference to FIGS. 3 to 5.

The list extractor 250 extracts a content list having a similar first pattern with respect to the second pattern according to the analysis result of the pattern analyzer 240. In this case, the list extracting unit 250 may extract a content list included in a specific album having a similar first pattern with respect to the second pattern, and the entire album of registered users having a similar first pattern with respect to the second pattern. It is also possible to extract a list of contents included in the.

The similarity calculator 260 calculates a similarity between the first pattern and the second pattern with respect to the content list extracted by the list extractor 250. Here, the similarity may be expressed as a percentage.

A detailed description of the similarity calculation of the similarity calculator 260 will be described later with reference to FIG. 6.

The transceiver 210 serves to transmit the similarity calculated by the similarity calculator 260. In addition, the transceiver 210 receives a list of contents requested to be registered from a registered user and receives a list of contents requested to be searched from a search user.

In addition, the transceiver 210 may transmit a similarity included in a predetermined threshold range according to a control command of the controller 230.

As a communication method between the transceiver 210 and a terminal of a registered user or a terminal of a search user, a wired communication method such as Ethernet, USB, IEEE 1394, serial communication, and parallel communication may be used. Wireless communication schemes such as infrared communication, Bluetooth, home RF and wireless LAN may also be used.

The controller 230 performs overall control of the transceiver 210, the storage 220, the pattern analyzer 240, the list extractor 250, the similarity calculator 260, and the content providing device 200. do.

3 is a diagram illustrating a pattern of increase and decrease of a content list according to an embodiment of the present invention.

In determining the similarity between the first pattern and the second pattern, the number of patterns may vary depending on the quantity of each type of content list constituting the pattern and the ratio thereof.

In the present invention, since each type of the content list is expressed as a percentage of 0 to 100%, the ratio range is 101. In addition, the quantity of each type of the content list may be determined by the user. The number pat _n of the pattern using the coverage 101 and the quantity n of each kind may be calculated by the following equation.

According to the above equation, if the quantity by type of the content list is 2, the number of patterns is 101, when the quantity by type of the content list is 3, the number of patterns is 5,151, and when the quantity by type of the content list is 4, The number is 176,851.

That is, the number of patterns increases as the quantity of each type of the content list increases. Thus, determining the similarity between the first pattern and the second pattern in consideration of all possible patterns increases the amount of computation of the pattern analyzer 240. You can.

Therefore, the pattern analyzer 240 of the present invention does not use all the above-described patterns, but determines the similarity between the first pattern and the second pattern by using the increase / decrease pattern 300.

3 is a case where a diagram illustrating the increase and decrease patterns 300 of the content list that can occur when each type number of the content list is a 4, a type number of the content list n number of increase or decrease pattern 300 vpat _n is Equation Can be calculated by

That is, the number of increase / decrease patterns 300 is determined only by the quantity of each type of the content list regardless of the range of the ratio. For example, when the quantity of each type of the content list is 2, the number of increase / decrease patterns is 2, and the content list If the quantity by type is 3, the number of increase and decrease patterns is 4, and when the quantity by type of the content list is 4, the number of increase and decrease patterns is 8.

Therefore, since the pattern analyzer 240 analyzes the first pattern and the second pattern by the number of times corresponding to the number of the increase / decrease patterns 300, the pattern analysis unit 240 analyzes the first pattern and the second pattern with fewer calculations and calculates the similarity. Can be determined.

As described above, the storage unit 220 may store the first pattern for the ratio of the quantity of each type of the content list included in the predetermined album, and the quantity of each kind may be set by the registered user.

3 shows that the quantity for each type of content list is four. For example, the genre, age group, time, feeling, weather, or situation are divided into four stages, and the quantity of the audio contents list of the divided stages is proportionally represented.

The first pattern stored by the registered user is compared with the second pattern input by the search user. Accordingly, the types of the content list constituting the first pattern and the second pattern are preferably the same in order. For example, if audio content is divided by its genre, and each point of the first pattern consists of blues, jazz, classes, and songs in order, each point of the second pattern must also be entered in blues, jazz, class, and song orders. will be.

4 is a view showing the slope of the increase and decrease pattern according to an embodiment of the present invention. Determining the similarity by analyzing the first pattern and the second pattern using the increase and decrease pattern may reduce the load of the calculation amount of the pattern analysis unit 240 due to the small amount of calculation, but according to the number of stored albums It is also possible to cause the first pattern similar to to be excessively extracted.

Therefore, the pattern analyzer 240 determines the similarity between the first pattern and the second pattern in consideration of the gradient 400 of the increase / decrease pattern.

That is, the pattern analyzer 240 calculates a slope of the extracted first pattern after extracting a first pattern similar to the second pattern, and compares it with the slope of the second pattern.

The gradient 400 of the increase / decrease pattern may be calculated by obtaining an average of the slopes of the entire straight lines in the graph of the ratio of the quantity of each type of the content list constituting the increase / decrease pattern.

Meanwhile, although the patterns are different, there may be a plurality of increase / decrease patterns 460 and 470 having the same slope 450 of the increase / decrease pattern.

Therefore, the pattern analyzer 240 may calculate the slope 400 of the increase / decrease pattern for a part of the graph instead of the whole point. For example, when there are four types of content list, the slope of the ratio of points 1, 2, and 3 is calculated or the slope of the ratio of points 2, 3, and 4 is calculated.

Accordingly, the pattern analyzer 240 may analyze the first pattern and the second pattern by using the slope according to the pattern.

5 is a view illustrating a pattern of increase and decrease of a slope according to an embodiment of the present invention.

The pattern analyzer 240 may analyze the first pattern and the second pattern by using the increase / decrease pattern 500 with respect to the slopes 510, 520, and 530 between straight lines connecting the ratio of the quantity of each type of the content list to each point. have.

Here, the inclination may be set according to a predetermined interval and the inclinations included in the interval may be regarded as the same. For example, when the interval of the slope is 36 degrees, if the difference between the slope between the first straight line and the second straight line of the first pattern is 30 degrees, and the difference between the slope between the first and second straight lines of the second pattern is 25 degrees Both are considered to be the same because they both fall within the 36 degree range.

6 is an exemplary diagram showing the calculated similarity according to an embodiment of the present invention, which shows a case where the quantity of each content list is 4.

Meanwhile, when the quantity for each type of the content list is n , the similarity sim between the first pattern and the second pattern may be calculated by the following equation.

Here, x and y represent the ratio by type of a 1st pattern, and the ratio by type of a 2nd pattern, respectively.

The similarity calculator 260 may calculate a similarity between the first pattern and the second pattern by using Equation 3, and may transmit the similarity included in the threshold range set by the user to the controller 230.

In addition, the controller 230 may transmit the similarity received through the transceiver 210 to the terminal of the search user, and the controller 230 transmits all similarities included in a predetermined threshold range to the transceiver 210. Can be sent to the terminal of the search user.

Accordingly, the terminal of the search user may display the received similarity. The ratio of the content list constituting the second pattern and the ratio of the content list constituting the first pattern may be displayed in the form of a table as shown in 610. It may be displayed in the form of an icon as shown in 620.

The transceiver 210 receives a content list according to the taste of the search user from the search user (S720). Here, the content list of the search user may be a content list registered by the search user as a registered user.

According to the content list of the search user and the content list of the registered user, the pattern analyzer 240 inputs the first pattern to the ratio of the quantity of each type of content list included in the album generated by the registered user and the search user. In operation S730, a second pattern of a ratio of quantities of each kind of content list is analyzed.

The pattern analyzer 240 may analyze the first pattern when the content list is registered by the registered user, and analyze the second pattern when the content list is input by the search user. When input, the first pattern and the second pattern may be analyzed.

Here, the pattern analyzer 240 may analyze the first pattern and the second pattern by using at least one of the increase / decrease pattern with respect to the ratio, the gradient of the increase / decrease pattern, and the increase / decrease pattern of the gradient.

Detailed descriptions of the increase / decrease pattern, the gradient of the increase / decrease pattern, and the increase / decrease pattern of the slope are described above with reference to FIGS. 3 to 5, and thus will be omitted.

According to the analysis result of the pattern analyzer 240, the list extractor 250 extracts a content list having a similar first pattern with respect to the second pattern (S740).

The extracted content list is transmitted to the similarity calculator 260, and the similarity calculator 260 calculates the similarity between the first pattern and the second pattern with respect to the received content list (S750). Here, the similarity may be expressed as a percentage.

A detailed description of the similarity calculation of the similarity calculator 260 will be omitted since it has been described above with reference to FIG. 6.

The calculated similarity is transmitted to the transceiver 210, and the transceiver 210 transmits the similarity received to the terminal of the search user (S760). At this time, the transceiver 210 may transmit the similarity included in the predetermined threshold range to the terminal of the search user according to the control command of the controller 230.

Accordingly, the search user may be provided with a content list of registered users whose tastes are similar to their own, and may access the corresponding content through the provided content list.

For example, a search user may be provided with a list of contents of a registered user through a web browser, and may access content linked by a hyperlink.
