Abstract

A method of recommending a query word using a domain property includes receiving a search keyword from a terminal of a user, the search keyword being input by the user; generating at least one recommendation query word concerned with the search keyword by using a property of an object of a domain when the search keyword belongs to the object of the domain; and providing the recommendation query word to the terminal of the user as an autocomplete query word for the search keyword.

First claim

What is claimed is:

1 . A method of recommending a query word, the method being implemented by a computer and comprising:
receiving a search keyword from a terminal of a user, the search keyword being input by the user; generating at least one recommendation query word concerned with the search keyword by using a property of an object of a domain when the search keyword belongs to the object of the domain; and providing the recommendation query word to the terminal of the user as an autocomplete query word for the search keyword.

2 . The method of claim 1 , wherein the recommendation query word is generated by combining the object and the property of the domain to which the search keyword belongs.

3 . The method of claim 1 , further comprising determining whether a query log for the search keyword exists,
wherein the recommendation query word is generated by using property information in the query log when the query log for the search keyword does not exists.

4 . The method of claim 3 , further comprising, when the query log for the search keyword exists, extracting at least one other recommendation query word concerned with the search keyword from the query log.

5 . The method of claim 1 , further comprising recording a query log of the recommendation query word when a search request using the recommendation query word occurs.

6 . A method of recommending a query word, the method being implemented by a computer and comprising:
receiving a search keyword from a terminal of a user, the search keyword being input by the user; extracting at least one first recommendation query word concerned with the search keyword from a query log for the search keyword; and generating at least one second recommendation query word concerned with the search keyword by using a property of an object of a domain to which the search keyword belongs; and providing at least one of the first and second recommendation query words to the terminal of the user as an autocomplete query word for the search keyword.

7 . A method of recommending a query word, the method being implemented by a computer and comprising:
transmitting a search key word when the search keyword input by a user is received from a terminal of the user; and receiving at least one recommendation query word concerned with the search keyword to display the recommendation query word on the terminal of the user as an autocomplete query word for the search keyword, wherein the recommendation query word comprises a query word generated by combining an object and a property of a domain to which the search keyword belongs.

8 . The method of claim 7 , wherein the recommendation query word comprises a first keyword part which is a part of the recommendation query word identical to the search keyword and a second keyword part which is a remaining part of the recommendation query word except for the first keyword part, and the first and second keyword parts are displayed to be distinguished from each other.

9 . The method of claim 7 , wherein the recommendation query word comprises a first keyword part which is a part of the recommendation query word identical to the search keyword and a second keyword part which is a remaining part of the recommendation query word except for the first keyword part,
the first and second keyword parts are displayed to be distinguished from each other, and the second keyword part is emphasized more than the first keyword part.

10 . The method of claim 7 , wherein the recommendation query word comprises another query word extracted from a query log for the search keyword,
the another query word comprises a first keyword part which is a part of the another query word identical to the search keyword and a second keyword part which is a remaining part of the another query word except for the first keyword part, and the first keyword part is displayed to be emphasized more than the second keyword part.

11 . A computer-readable recording medium recorded with instructions, the instructions, which are executed by a computer system, causing the computer system to provide an autocomplete query word by using a method comprising:
receiving a search keyword from a terminal of a user, the search keyword being input by the user; generating at least one recommendation query word concerned with the search keyword by using a property of an object of a domain when the search keyword belongs to the object of the domain; and providing the recommendation query word to the terminal of the user as an autocomplete query word for the search keyword.

12 . A system of recommending a query word, the system comprising:
a memory in which at least one program is loaded; and at least one processor, wherein the at least one program, when executed by the at least one processor, causes the at least one processor to perform: receiving a search keyword from a terminal of a user, the search keyword being input by the user; generating at least one recommendation query word concerned with the search keyword by using a property of an object of a domain when the search keyword belongs to the object of the domain; and providing the recommendation query word to the terminal of the user as an autocomplete query word for the search keyword.

13 . The system of claim 12 , wherein the recommendation query word is generated by combining the object and the property of the domain to which the search keyword belongs.

14 . The system of claim 12 , wherein the recommendation query word is generated by using property information in the query log when the query log for the search keyword does not exists.

15 . The system of claim 14 , wherein, in accordance with the program, the processor further performs extracting at least one other recommendation query word concerned with the search keyword from the query log when the query log of the search keyword exists.

16 . The system of claim 12 , wherein, in accordance with the program, the processor further performs recording a query log of the recommendation query word when a search request using the recommendation query word occurs.

17 . The system of claim 12 , wherein the recommendation query word comprises a first keyword part which is a part of the recommendation query word identical to the search keyword and a second keyword part which is a remaining part of the recommendation query word except for the first keyword part, and the first and second keyword parts are displayed on the terminal of the user to be distinguished from each other.

18 . The system of claim 17 , wherein the first and second keyword parts are displayed such that the second keyword part is emphasized more than the first keyword part.
