Abstract

Methods and apparatuses for providing tag information. According to a method of outputting tag information in a user terminal, tag information and attribute information are obtained by reading at least one tag and then mapped to a key word and stored, and when a message content is input through a message-writing application, tag information corresponding to a key word can be extracted and displayed if the key word is included in the message content.

Claims

1. A user terminal comprising:

at least one hardware processor;

a reader configured to obtain tag information and attribute information by reading at least one tag, the attribute information including a key word;

a storage, after obtaining the tag information from the reader, generating keyword-mapped tag information by mapping the key word on the tag information obtained from the reader, and storing the keyword-mapped tag information;

an input unit configured to receive a message content;

a searching unit configured to search the storage after the keyword-mapped tag information is stored in the storage, and extract the keyword-mapped tag information stored in the storage corresponding to the key word if the key word is included in the message content; and

an output unit configured to output the extracted keyword-mapped tag information,

wherein at least one of the reader and the searching unit are embodied on the at least one hardware processor.

2. The user terminal of claim 1, wherein the output unit comprises a display unit configured to display the extracted keyword-mapped tag information in a form of a visual information.

3. The user terminal of claim 1, wherein the searching unit analyzes the message content in units of morphemes and determines whether the key word is included in the message content.

4. The user terminal of claim 1, further comprising:

a message generating unit configured to generate a message containing the message content; and

a communication unit configured to request the generated message to be sent to another terminal,

wherein the searching unit searches for the key word in the message content when the generated message is requested to be sent.

5. The user terminal of claim 2, further comprising a control unit configured, if multiple key words are included in the message content, to control the key words to be displayed in descending order of a number of tag information corresponding to the key words from the top of the display unit.

6. The user terminal of claim 2, wherein the attribute information further comprises an expiration date of the tag information, and further comprising a control unit configured, if multiple key words are included in the message content, to control the tag information to be displayed from an earliest expiration date of the tag information corresponding to the key words after a current date from the top of the display unit.

7. The user terminal of claim 6, wherein, if N or more tag information is extracted corresponding to the key words, N being a natural number, the control unit is configured to control tag information having the expiration date that is after a current date and before a predetermined date to be displayed through the display unit.

8. The user terminal of claim 6, wherein the control unit is configured to delete tag information having past the expiration date from the storage a.

9. The user terminal of claim 1, wherein the tag information that is obtained is stored in association with identification information of a requestor that requests storage of the tag information.

10. The user terminal of claim 1, wherein the user terminal transmits a registration request to register the tag information obtained by the reader in association with identification information of the user terminal or identification information of a user of the user terminal.

11. The user terminal of claim 1, wherein the searching unit extracts the keyword-mapped tag information corresponding to the keyword by determining if the keyword and the keyword-mapped tag information are mapped and stored in association with identification information of the user terminal or identification information of a user of the user terminal.

12. A method of outputting tag information in a user terminal, the method comprising:

obtaining tag information and attribute information by reading at least one tag, wherein the attribute information includes a key word;

after obtaining the tag information from a reader, generating keyword-mapped tag information by mapping the key word on the tag information obtained from the reader;

storing the keyword-mapped tag information in a storage;

receiving a message content;

searching the storage after the keyword-mapped tag information is stored in the storage, and extracting the keyword-mapped tag information stored in the storage corresponding to the key word if the key word is included in the message content; and

outputting the extracted keyword-mapped tag information.

13. The method of claim 12, wherein the outputting the extracted keyword-mapped tag information comprises displaying the extracted keyword-mapped tag information in a form of a visual information.

14. The method of claim 12, wherein the extracting of the keyword-mapped tag information corresponding to the key word comprises:

extracting words in units of morphemes when the message content is input; and

extracting the keyword-mapped tag information corresponding to the key word if the extracted words and the key word are determined to be matched with one another.

15. The method of claim 13, wherein, in the displaying of the extracted keyword-mapped tag information, the tag information of the key word having more tag information corresponded thereto is displayed first.

16. The method of claim 13, wherein the attribute information further comprises an expiration date of the tag information, and

wherein, in the displaying of the extracted tag information, the tag information of the key word corresponding to the tag information having an earlier expiration date is displayed first.

17. A tag information providing system comprising:

a user terminal, having a processor, configured to request a message including a message content to be sent to a terminating terminal;

a message center configured to send the message to the terminating terminal in response to said request and to request a key word search for the message content; and

a server configured to generate keyword-mapped tag information by mapping the key word on tag information obtained from a reader, and store the keyword-mapped tag information and attribute information per terminal information in a storage, the attribute information including a key word, and to search the storage after keyword-mapped tag information is stored in the storage, and extract the keyword-mapped tag information stored in the storage corresponding to the key word and provide the tag information to the user terminal if the key word is included in the message content.

18. The tag information providing system of claim 17, wherein the user terminal comprises a reader and is configured to obtain the tag information and the attribute information by reading at least one tag through the reader and to register the tag information and attribute information that is obtained along with terminal information.

19. The tag information providing system of claim 17, wherein, if multiple key words are included in the message content, the server is configured to extract and provide the tag information to the user terminal in descending order of a number of tag information corresponding to the key words.

20. The tag information providing system of claim 19, wherein the attribute information further comprises an expiration date, and

wherein the server is configured to provide the tag information to the user terminal by arranging the extracted tag information in chronological order of the expiration date.

21. The tag information providing system of claim 17, wherein the attribute information further comprises an expiration date of the tag information, and

wherein the server is configured to provide the tag information to the user terminal by extracting the tag information having the expiration date that is before a predetermined date.
