Abstract

Retrieving information from information sources using links. A set of information sources is preprocessed to extract content from text and existing links in the information sources according to some predetermined criteria. A set of search results is generated from amongst the preprocessed information sources in response to a received search query.

Claims

1. A method comprising:

preprocessing a set of information sources to extract content from text and existing links in said set of information sources according to some predetermined criteria; and

receiving a search query and generating a set of search results from amongst the preprocessed information sources in response thereto.

2. The method of claim 1 further comprising:

storing the extracted content in a database.

3. The method of claim 1 further comprising:

tagging said content extracted from the links in said information sources.

4. The method of claim 1 further comprising:

displaying said set of search results.

5. The method of claim 1, wherein said extracting further comprising:

limiting the depth of information extracted from the set of information sources in response to an input;

limiting maximum amount of information extracted from the set of information sources;

limiting maximum amount of information extracted from a page of the set of information sources; and

ranking the set of information sources automatically or in response to an input.

6. The method of claim 1, wherein said extracting further comprising:

clustering one or more first information sources if said one or more information sources are related to each other.

7. The method of claim 1 wherein the set of information sources comprises electronic mail, instant messenger, workspace, calendar, web pages and combinations thereof.

8. The method of claim 1, wherein said link comprises a hypertext link, a hyper media link and an embedded object.

9. A system comprising:

a preprocessing module for preprocessing a set of information sources to extract content from text and existing links in said set of information sources according to some predetermined criteria; and

a search module for receiving a search query and generating a set of search results from amongst the preprocessed information sources in response thereto.

10. The system of claim 9 further comprising a tagging module for tagging said content extracted from the links in said set of information sources.

11. The system of claim 9 further comprising:

a database for storing the extracted content.

a ranking module for ranking the set of information sources automatically or in response to an input; and

a display module for displaying a set of search results.

12. The system of claim 9, wherein said extraction module further comprising:

a clustering module for clustering one or more first information sources if said sources are related to each other.

13. The system of claim 9, further comprising means for limiting the depth of extraction from the set of information sources in response to an input.

14. The system of claim 9, wherein the set of information sources comprises electronic mail, instant messenger, workspace, calendar, web pages and combinations thereof.

15. The system of claim 9, wherein said link comprises a hypertext link, a hyper media link and an embedded object.

16. A computer program stored on a machine-readable medium product, comprising instructions operable to cause a programmable processor to:

preprocess a set of information sources to extract content from text and existing links in said set of information sources according to some predetermined criteria; and

receive a search query and generate a set of search results from amongst the preprocessed information sources in response thereto.

17. The product of claim 16 further comprising instructions to:

tag said content extracted from said links in the information sources;

display a set of results; and

limit the depth of extraction from the set of information sources in response to an input.
