Abstract

An example information query method including receiving a query parameter including keyword information and one or more pieces of language feature information; generating one or more query request strings corresponding to the one or more pieces of language feature information respectively according to the keyword information; determining corresponding position intervals of the one or more pieces of language feature information in a second index according to a pre-established first index, the first index including a mapping relationship between the language feature information and the position intervals of the second index, the second index including a mapping relationship between keywords and information pages; and acquiring query results corresponding to the one or more query request strings respectively according to the determined corresponding position intervals of the one or more pieces of language feature information in the second index. The techniques of the present disclosure reduce the cost of multi-language query.

First claim

What is claimed is:

1. An information query apparatus comprising:
one or more processors;
a memory coupled to the one or more processors, the memory storing a plurality of executable modules, executable by the one or more processors that when executed by the one or more processors cause the one or more processors to perform acts including:
receiving a query parameter including keyword information and one or more pieces of language feature information, the language feature information being input by a user, the language feature information indicating a target language of a query result to be obtained, the keyword information including one or more keywords in one or more languages;
generating one or more query request strings corresponding to the one or more pieces of language feature information respectively according to the keyword information, wherein generating the one or more query request strings corresponding to the one or more pieces of language feature information respectively according to the keyword information includes:
determining one or more target languages of the query result according to the one or more pieces of language feature information in the query parameter;
translating keywords in the query parameter into one or more target language keywords corresponding to the language feature information respectively; and
generating the one or more query request strings respectively according to the one or more target language keywords;

determining corresponding position intervals of the one or more pieces of language feature information in a second index according to a pre-established first index, the first index including a mapping relationship between the language feature information and the position intervals of the second index, the second index including a mapping relationship between the one or more keywords and information pages; and
acquiring one or more query results corresponding to the one or more query request strings respectively according to the determined corresponding position intervals of the one or more pieces of language feature information in the second index.

2. The information query apparatus of claim 1 , wherein a respective piece language feature information of the one or more pieces of language feature information indicates a respective target language of the one or more query results.

3. The information query apparatus of claim 1 , wherein the query parameter further includes a constraint condition.

4. The information query apparatus of claim 3 , wherein the constraint condition includes a number of target query results returned from the query results.

5. The information query apparatus of claim 3 , wherein the constraint condition includes a display manner of the query results.

6. The information query apparatus of claim 3 , the acts further comprising processing the query results according to the constraint condition to obtain a target query result.

7. An information query method comprising:
receiving a query parameter including keyword information and one or more pieces of language feature information, the language feature information being input by a user;
generating one or more query request strings corresponding to the one or more pieces of language feature information respectively according to the keyword information, the keyword information including one or more keywords in one or more languages, wherein generating the one or more query request strings corresponding to the one or more pieces of language feature information respectively according to the keyword information includes:
determining one or more target languages of the query result according to the one or more pieces of language feature information in the query parameter;
translating keywords in the query parameter into one or more target language keywords corresponding to the language feature information respectively; and
generating the one or more query request strings respectively according to the one or more target language keywords;

determining a first pre-established index that includes a mapping relationship between respective piece of language feature information and position intervals of the respective language feature information in a second index;
determining the second index that includes a mapping relationship between the keywords and information pages;
determining corresponding position intervals of the respective piece of language feature information in the second index; and
acquiring one or more query results of the corresponding position intervals of the respective piece of language feature information in the second index.

8. The information query method of claim 7 , wherein the respective piece of language feature information indicates a target language of the one or more query results.

9. The information query method of claim 7 , wherein mapping relationships between the keywords and the information pages corresponding to the keywords having the same language feature information are placed in adjacent positions of the second index.

10. The information query method of claim 7 , wherein the acquiring the one or more query results of the corresponding position intervals of the respective piece of language feature information in the second index includes:
acquiring the one or more query results corresponding to query request strings of the respective piece of language feature information in the corresponding position intervals of the respective piece of language features information in the second index.

11. The information query method of claim 7 , wherein the query parameter further includes a constraint condition for determining a first query result.

12. The information query method of claim 11 , wherein the constraint condition includes a number of target query results returned from the query results.

13. The information query method of claim 11 , wherein the constraint condition includes a display manner of the query results.

14. The information query method of claim 11 , further comprising performing a first processing on the one or more query results corresponding to the query request strings of the pieces of language feature information according to the constraint condition in the query parameter to obtain a target query result.

15. The information query method of claim 14 , further comprising determining the first processing according to the constraint condition.

16. One or more non-transitory memories stored thereon computer-executable instructions, executable by one or more processors, to cause the one or more processors to perform acts comprising:
receiving a query parameter including keyword information and one or more pieces of language feature information, the language feature information being input by a user, the language feature information indicating a target language of a query result to be obtained, the keyword information including one or more keywords in one or more languages;
generating one or more query request strings corresponding to the one or more pieces of language feature information respectively according to the keyword information, wherein generating the one or more query request strings corresponding to the one or more pieces of language feature information respectively according to the keyword information includes:
determining one or more target languages of the query result according to the one or more pieces of language feature information in the query parameter;
translating keywords in the query parameter into one or more target language keywords corresponding to the language feature information respectively; and
