This application claims priority from Korean Patent Application No. 10-2010-0014731, filed on Feb. 18, 2010 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.
1. Field
Methods and apparatuses consistent with exemplary embodiments relate to managing a tag of multimedia contents, and more particularly, to managing a tag of multimedia contents, wherein a tag providing server provides a recommendation tag list to a mobile device based on additional information regarding multimedia contents, received from the mobile device, and the recommendation tag list is renewed based on a tag that is selected or input by using the mobile device.
2. Description of the Related Art
A tag is input to multimedia contents using, for example, a mobile tagging method. In the mobile tagging method, a user obtains information about an object by searching a resource such as an encyclopedia or the Internet while referring to a photographed image or by using global positioning system (GPS) information of a device. The user inputs the information relevant to the object as a tag by using an input unit such as a keypad to manage images and tags.
Alternatively, in a geotagging method, GPS coordinate information that is obtained using a GPS device attached to a camera is used as a tag. For example, GPS information may be combined with an image as an exchangeable image file format (EXIF) property.
Alternatively, in a contents parsing method, information that is obtained by parsing contents is used as a tag.
One or more exemplary embodiments provide a method and apparatus for managing a tag of multimedia contents, wherein a tag providing server provides a recommendation tag list to a mobile device based on additional information regarding the multimedia contents, received from the mobile device, and the recommendation tag list is renewed based on a tag that is selected or input by using the mobile device.
One or more exemplary embodiments also provide a computer readable recording medium for executing the method.
According to an aspect of an exemplary embodiment, there is provided a method of managing a tag, in a mobile device, the method including: photographing multimedia content that is identified by a content identifier (ID); obtaining additional information regarding the multimedia content; transmitting a tag request message including a device ID, the content ID, and the additional information to a tag providing server; and receiving a tag response message including a recommendation tag list from the tag providing server.
The additional information may include at least one of photographing time, position information, angle of view, focal distance, direction, altitude, acceleration, inclination, and point of interest (POI) map information.
The method may further include automatically selecting at least one tag from the recommendation tag list based on an external input or a predetermined preference or receiving a tag based on an external input.
The method may further include transmitting a tag renewal message including the selected tag or the input tag, the device ID, the content ID, and the additional information, to the tag providing server.
The method may further include transmitting the selected tag or the input tag, the device ID, the content ID, and the multimedia contents, to a contents database (DB) server.
The method may further include storing the content ID and the additional information.
According to an aspect of another exemplary embodiment, there is provided a method of managing a tag, in a tag providing server, the method including: receiving a tag request message including a device ID, a content ID of multimedia content, and additional information regarding the multimedia content, from a mobile device; generating a recommendation tag list based on the received additional information; and transmitting a tag response message including the recommendation tag list to the mobile device.
In the generating of the recommendation tag list, the recommendation tag list may be generated based on a similarity between stored additional information and the received additional information.
The method may further include storing the content ID, the additional information, and the recommendation tag list.
The method may further include receiving a tag renewal message including the device ID, the content ID, the additional information, and the tag selected or input by using the mobile device, from the mobile device.
The method may further include renewing the stored recommendation tag list by using the tag selected or input by using the mobile device.
According to an aspect of another exemplary embodiment, there is provided a computer readable recording medium having embodied thereon a program for executing the above-described method.
According to an aspect of another exemplary embodiment, there is provided a mobile device including: a photographing unit which photographs multimedia content that is identified by a content ID; an additional information obtaining unit which obtains additional information regarding the multimedia content; a tag request message transmitting unit which transmits a tag request message including a device ID, the content ID, and the additional information, to a tag providing server; and a tag response message receiving unit which receives a tag response message including a recommendation tag list from the tag providing server.
According to an aspect of another exemplary embodiment, there is provided a tag providing server including: a tag request message receiving unit which receives a tag request message including a device ID, a content ID of multimedia content, and additional information regarding the multimedia content from a mobile device; a recommendation tag list generating unit which generates a recommendation tag list based on the received additional information; and a tag response message transmitting unit which transmits a tag response message including the recommendation tag list to the mobile device.
According to an aspect of another exemplary embodiment, there is provided a method of managing a tag for multimedia content, the method including: capturing multimedia content; obtaining additional information regarding the multimedia content; transmitting, to a tag providing server, a tag request message comprising the additional information; and receiving, from the tag providing server, a tag response message comprising a recommendation tag list for the multimedia content.

Exemplary embodiments will now be described more fully with reference to the accompanying drawings, in which like reference numerals in the drawings denote like elements. In the drawings, the thicknesses of layers and regions may be exaggerated for clarity. Furthermore, expressions such as “at least one of,” when preceding a list of elements, modify the entire list of elements and do not modify the individual elements of the list.
However, when the position information providing unit is included in the mobile device 310 or 600, the position information providing unit provides a position of the mobile device 310 or the mobile device 600 instead of a position of the Eiffel Tower which is the subject being photographed. Thus, if other additional information is not used, accuracy of information regarding a captured image may be decreased for the use of the tag.
The mobile device 310 or 600 may obtain additional information such as photographing time, angle of view, and a focal distance from the photographing unit 610.
Also, the mobile device 310 or 600 may obtain at least one of position information such as GPS information and POI map information of a subject from the position information providing unit (not shown), a direction of a subject from the direction information providing unit (not shown), and an altitude of a subject from the altitude information providing unit (not shown). For example, the direction information providing unit (not shown) may operate as a compass, and the altitude information providing unit (not shown) may operate as an altimeter.
Also, the mobile device 310 or 600 may obtain additional information including acceleration and inclination of a subject from the acceleration sensor unit (not shown).
