Abstract

A system (10) for automated retrieval of information from one or more information sources (30) includes user parameters (14) that specify an attribute (114, 116, 118, 120) of a user (102). A library (18) contains filters (20) that each specify one or more search parameters for an associated attribute (114, 116, 118, 120). A translator (16) selects one or more filters (20) from the library (18) in accordance with the user parameters (14). A searcher (28) retrieves information from the information sources (30) using the selected filters (20).

Claims

1. A system for automated retrieval of information from one or more information sources, comprising:

at least one attribute that;

comprises a business role of information describing a particular purpose for which information may be used;

is associated with a work activity corresponding to a particular usage of information; and

indicates selected information for which retrieval is likely to be desirable for the usage;

a library containing a plurality of information filters, each information filter specifying one or more search parameters corresponding to the attribute;

a translator coupled to the library and operable to select one or more information filters from the library in accordance with the attribute; and

a searcher coupled to the translator and the information sources, the searcher operable to generate one or more search requests according to the search parameters specified by the selected information filters, the searcher further operable to retrieve information from the information sources using the generated search requests.

2. The system of claim 1, wherein the attribute is a user attribute associated with a particular user of the system.

3. The system of claim 1, wherein the attribute is a user attribute that comprises an industry associated with a particular user of the system.

4. The system of claim 1, wherein each of the information filters is associated with a particular one of a plurality of attributes, each attribute:

comprising a business role of information describing a particular purpose for which information may be used;

associated with a work activity corresponding to a particular usage of information; and

indicating selected information for which retrieval is likely to be desirable for the usage.

5. The system of claim 1, wherein each of the information filters comprises:

a database/file listing; and

one or more search terms.

6. The system of claim 1, further comprising a modifier operable to automatically modify the search parameters specified by an information filter in response to the information being retrieved.

7. The system of claim 1, further comprising an interactor operable to elicit responses from a user in response to the information being retrieved using one or more feedback prompts.

8. The system of claim 1, further comprising communication parameters associated with each information source, the searcher accessing the communication parameters to retrieve information from the information sources.

9. A method for automated retrieval of information from one or more information sources, comprising:

retrieving a user profile defined by one or more user parameters, the user parameters comprising at least one attribute that;

comprises a business role of information describing a particular purpose for which information may be used;

is associated with a work activity corresponding to a particular usage of information; and

indicates selected information for which retrieval is likely to be desirable for the usage;

associating the user parameters with one or more information filters selected from a plurality of stored information filters, each information filter specifying one or more search parameters corresponding to an associated attribute;

generating one or more search requests according to the search parameters specified by the selected information filters;

issuing the search requests to the information sources; and

retrieving information from the information sources in accordance with the search requests.

10. The method of claim 9, wherein the attribute is a user attribute associated with a particular user of the system.

11. The method of claim 9, wherein the attribute is a user attribute that comprises an industry associated with a particular user of the system.

12. The method of claim 9, wherein each of the information filters is associated with a particular one of a plurality of attributes, each attribute:

comprising a business role of information describing a particular purpose for which information may be used;

associated with a work activity corresponding to a particular usage of information; and

indicating selected information for which retrieval is likely to be desirable for the usage.

13. The method of claim 9, further comprising the step of accessing communication parameters associated with each information source, the searcher accessing the communication parameters to retrieve information from the information sources.

14. The method of claim 9, wherein each information filter comprises:

a database/file listing; and

one or more search terms.

15. A method for automated retrieval of information from one or more information sources, comprising:

retrieving a user profile defined by one or more user parameters, the user parameters comprising at least one attribute that;

comprises a business role of information describing a particular purpose for which information may be used;

is associated with a work activity corresponding to a particular usage of information; and

indicates selected information for which retrieval is likely to be desirable for the usage;

associating the user parameters with one or more information filters selected from a plurality of stored information filters, at least one information filter specifying one or more search parameters corresponding to the attribute;

generating one or more search requests according to the search parameters specified by the selected filters;

issuing the search requests to the information sources;

retrieving information from the information sources in accordance with the search requests;

eliciting responses from the user concerning the retrieved information; and

modifying the selected information filters in accordance with the responses.

16. The method of claim 15, wherein eliciting responses includes requesting the user to assess the relevance of the specified search parameters.

17. The method of claim 15, wherein eliciting responses includes requesting the user to evaluate the volume of information retrieved.

18. The method of claim 15, wherein the attribute is a user attribute associated with a particular user of the system.

19. The method of claim 15, wherein each of the information filters is associated with a particular one of a plurality of attributes, each attribute:

comprising a business role of information describing a particular purpose for which information may be used;

associated with a work activity corresponding to a particular usage of information; and

indicating selected information for which retrieval is likely to be desirable for the usage.

20. The method of claim 15, wherein the responses are elicited using one or more feedback prompts.
