Here, the association information may be acquired based on at least one of the attribute information and the context information for the corresponding content described above.

Such association information may include at least one of associated keyword information, associated image information, associated audio information, and associated moving image information. For example, a typical example of related keyword information is an associated search word that is mainly used in a portal site or the like.

In addition, the association information may include emotion information related to the attribute information and / or the keyword, image, and the like extracted as the context information. For example, if the image color of the content is a "red" system, keywords such as "warm" and "passionate" may be acquired as emotion information associated with the content. Further, when the title of the content or the result of image analysis of the content is related to a "mountain", keywords such as "refreshing", "calmness", etc. may be acquired as emotion information associated with the content .

When the content feature information for the selected content is extracted through the step S420, the controller 180 compares the extracted content feature information with the information about the inclination of friends of the mobile terminal user registered at the SN site (S430 (Refer to FIG. 7A and FIG. 7A). As a result of the comparison, at least one friend matching the predetermined reference value or more is determined (S440). Or if there are no friends matched with a preset reference value or more, the user may determine a certain number of friends in the order of matching the highest percentage.

Here, the SN site may be an SN site registered in the mobile terminal 100. And the friend may be a person registered by the user as a friend on the account-registered SN site. At this time, the comparison range of the content feature information and the inclination information of the friends can be determined (selected) by the user, for example. For example, the user may enter an instruction to perform the comparison only on friends registered at a particular SN site. Alternatively, the user may enter the command to perform the comparison on all friends in all SN sites registered in his / her mobile terminal. The input of the command may be performed through the input unit 130 of the mobile terminal.

The propensity information may include at least one of statistical propensity information about the person, interest information of the person, and social activity information of the person.

Here, the statistical propensity information may be acquired based on the member information registered in the corresponding SN site of the person (i.e., friend). That is, the statistical tendency information can be acquired based on the member basic information such as the age, sex, education, occupation, address, salary, etc. of the person.

For example, depending on the age, gender, occupation, etc. of the person, the kind and content of the content that the person is likely to be interested in or preferring can be empirically or statistically determined. As a more specific example, it can be predicted that friends in the mid-to-early-30s are statistically interested in information related to employment, so that they can find content such as job articles or web articles in which recruiting information is disclosed That is, it can be matched.

Here, the interest information of the corresponding person means, for example, information related to the interest field, hobby, etc. directly registered in the membership process of the corresponding SN site. For example, a friend who registers literature as an area of interest may be matched with content such as a specific human-edited book or a web article about a novel book. As another example, a friend who registers music appreciation as a hobby may be matched with content such as a classical music file.

Here, the social activity information refers to information that can be acquired based on the social networking activity of the person. Such social activity information may include, for example, authoring activity, review activity, subscription / browsing activity, comment, favorite registration, and content upload / download activity of the person on the Internet. In addition, information such as membership activities, group affiliation activities, personal relationships, etc., on the Internet (ie, online) of the person or offline can be a valuable data that can identify the tendency of the person.

Such social activity information is often collected, stored, and classified in the SN site itself in recent years. This is because the operator of the SN site wants to provide more suitable information to a specific person based on the inclination information of people who are registered and active in his SN site.

The propensity information as described above can be acquired by the controller 180 receiving the information from the corresponding SN site or directly acquiring information by connecting to the corresponding SN site.

At this time, the inclination information of the friends can be received / collected in real time only when the user of the mobile terminal wants to transmit the specific contents to the SN site. However, By periodically accessing the site, the propensity information of friends in the SN site can be obtained in advance and stored / updated in the memory unit 160. According to the latter, the comparison and determination process (steps S430 and S440) may proceed more quickly.

If the friends matching the corresponding content are determined through the comparison and determination process, the determined friends are displayed in a list on the display screen 151a of the mobile terminal 100 (S450). An example thereof is shown in FIG. 7 (b).

Referring to the display screen 151a of Fig. 7 (b), the friends 91 to 96 matching the corresponding contents (refer to reference numeral 60 in Fig. 5 and Fig. 6) Are displayed.

Thereafter, the user can select friends to actually transmit the contents among the friends listed above (S460). For example, in the case of FIG. 8 (a), friends corresponding to the reference numbers 91, 93, and 96 are selected. When the friends to transmit the content are selected, the controller 180 accesses the SN site through the wireless communication unit 110 and transmits the content to the selected friends (S470).

As described above, according to the content transmission method and the mobile terminal implementing the same, the feature information of the content is compared with the inclination information of the friends registered in the SN site (Social Network site), and according to the comparison result, There is an advantage that content can be easily transmitted to friends having the inclination information matching with the content feature information. In addition, the present invention can easily search for a friend of an SN site that is expected to be interested in a specific content, and accordingly, it is possible to transmit content having high utility to the friend.

In the above description, the content itself is transmitted to the friends matching the selected content. However, the information transmitted to the friends need not necessarily be the selected content itself, and related information (e.g., For example, it is obvious that a uniform resource locator (URL) or link information, or a text, image information, or the like that introduces the content may be transmitted.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the following claims And changes may be made without departing from the spirit and scope of the invention.
