Abstract

A method and device index resource content in a computer network. The computer network includes at least a first computer as a search engine and at least a second computer as a resource content site where a resource content of a user is stored. A determination is made as to whether the resource content is linked to a user-defined indexing code. The user-defined indexing code is used to process the resource content to obtain a set of information describing the resource content. The user-defined indexing code is executed in response to determining that the resource content is linked to the user-defined indexing code. The set of information describing the resource content is obtained as an indexing result in response to the executing.

Claims

1. A method for indexing resource content in a computer network, the computer network comprising at least a first computer as a search engine and at least a second computer as a resource content site where a resource content of a user is stored, the method comprising:

determining whether the resource content is linked to a user-defined indexing code, wherein the user is an owner of the resource content, and wherein the user-defined indexing code comprises executable code defined by the user that executes an indexing algorithm also defined by the user, wherein the indexing algorithm instructs the search engine on how to process the resource content to obtain a set of information describing the resource content as defined by the user, wherein user-defined indexing code is included within the resource content;

executing the user-defined indexing code in response to determining that the resource content is linked to the user-defined indexing code; and

obtaining, in response to the executing, the set of information describing the resource content as an indexing result.

2. The method according to claim 1, further comprising:

storing the indexing result obtained upon executing the user-defined indexing code in an index database of the search engine.

3. The method according to claim 1, further comprising:

in response to determining that the resource content fails to be linked to any user-defined indexing code, indexing the resource content by a predetermined indexer.

4. The method according to claim 1, further comprising:

downloading the resource content and related information linked to by the resource content to the search engine prior to determining whether the resource content is linked to the user-defined indexing code, and wherein determining whether the resource content is linked to the user-defined indexing code and executing the user-defined indexing code are performed by the search engine.

5. The method according to claim 1, wherein determining whether the resource content is linked to the user-defined indexing code and executing the user-defined indexing code are performed by the resource content site.

6. The method according to claim 5, further comprising:

determining by the resource content site whether an access to the resource content is from a crawler of the search engine or from a human viewer; and

if the access is from a crawler of the search engine, further determining whether the resource content is linked to the user-defined indexing code.

7. The method according to claim 1, wherein the user-defined indexing code describes a self-defined weight defined by the user for an index term in the resource content.

8. The method according to claim 1, wherein the user-defined indexing code further comprises the user using at least one of content and organization of the resource content as an index term and weighting the index term.

9. The method according to claim 1, wherein the user-defined indexing code is obtained based on a code template, and the code template corresponds to a content template of the resource content.

10. The method according to claim 1, wherein the user-defined indexing code is implemented by a script file.

11. The method according to claim 1, wherein the computer network is a managed network environment.

12. An information processing system for indexing resource content in a computer network, the computer network comprising at least the information processing system and at least another information processing system as a resource content site where a resource content of a user is stored, the information processing system comprising:

memory;

a processor communicatively coupled to the memory;

a search engine communicatively coupled to the memory and the processor;

a determination apparatus communicatively coupled to the memory and the processor, the determination apparatus configured to receive the resource content and a set of related information linked to by the resource content that is downloaded by a crawler of the search engine, and to determine whether the set of related information linked to by the resource content comprises user-defined indexing code, wherein the user is an owner of the resource content, and wherein the user-defined indexing code comprises executable code defined by the user that executes an indexing algorithm also defined by the user, wherein the indexing algorithm instructs the search engine on how to process the resource content so as to obtain information describing the resource content as defined by the user, wherein user-defined indexing code is included within the resource content; and

an interpreter communicatively coupled to the memory and the processor, the interpreter configured to execute the user-defined indexing code and obtaining information describing the resource content as an indexing result.

13. The information processing system according to claim 12, further comprising:

an index database which is configured to store the indexing result from the interpreter.

14. The information processing system according to claim 12, further comprising:

a predetermined indexer, which is configured to index the resource content if the determination apparatus determines that there fails to be user-defined indexing code linked to by the resource content.

15. The information processing system according to claim 12, wherein the user-defined indexing code describes a self-defined weight defined by the user for an index term in the resource content.

16. The information processing system according to claim 12, wherein the user-defined indexing code is implemented by the user using at least one of content and organization of the resource content as an index term and assigning a weight to the index term.

17. The information processing system according to claim 12, wherein the user-defined indexing code is obtained based on a code template and the code template corresponds to a content template of the resource content.

18. The information processing system according to claim 12, wherein the computer network is a managed network environment.

19. A computer program product for indexing resource content in a computer network, the computer network comprising at least a first computer as a search engine and at least a second computer as a resource content site where a resource content of a user is stored, the computer program product comprising

a storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising:

determining whether the resource content is linked to a user-defined indexing code, wherein the user is an owner of the resource content, and wherein the user-defined indexing code comprises executable code defined by the user that executes an indexing algorithm also defined by the user that processes the resource content to obtain a set of information describing the resource content, wherein user-defined indexing code is included within the resource content;

executing the user-defined indexing code in response to determining that the resource content is linked to the user-defined indexing code;

obtaining, in response to the executing, the set of information describing the resource content as an indexing result; and

downloading the resource content and related information linked to by the resource content to the search engine prior to determining whether the resource content is linked to the user-defined indexing code, and wherein determining whether the resource content is linked to the user-defined indexing code and executing the user-defined indexing code are performed by the search engine.

20. The computer program product according to claim 19, wherein the method further comprises:

determining whether an access to the resource content is from one of a crawler of the search engine and from a human viewer; and

determining whether the resource content is linked to the user-defined indexing code in response to the access from the crawler of the search engine.
