Abstract

Systems, devices, and methods for contextual management extract context information and content information from a collection of stored digital content items; generate an index of the extracted context information and content information; store the indexed context information and content information; receive a query from a computing device, wherein the query is associated with a user; determine a context of the user; determine a context of a user activity; determine contents of the query; generate a recommendation in response to the query based on the context of the user, the context of the user activity, and the contents of the query; and return the recommendation to the computing device.

Claims

1. A method for contextual management, the method comprising:

performing a first process repeatedly, wherein the first process includes;

(i) extracting content information corresponding to a new or modified content item from a collection of digital content items to be distributed in a plurality of locations on a network,

(ii) normalizing the new or modified content item corresponding to the extracted content information,

(iii) sending the normalized content item to a data warehouse, which is a local storage for managing a normalized content item, and

(iv) registering keywords extracted from the new or modified content item to the data warehouse;

performing a second process repeatedly, wherein the second process includes;

(i) examining a new content item of the data warehouse,

(ii) generating an index from content information of the new content item, and

(iii) updating an index database using the generated index,

receiving a query from a computing device, wherein the query is automatically generated by a client program of the computing device in response to a user'"'"'s operations for an application;

determining a context of the user associated with the received query;

generating an enhanced query by using a registered keyword corresponding to the contents of the query according to the reception of the query;

performing a search based on the context of the user and contents of the enhanced query generated by using the registered keyword;

generating a recommendation according to a result of the search and an index in the index database; and

returning the generated recommendation to the client program of the computing device.

2. The method of claim 1, wherein the recommendation is a storage location.

3. The method of claim 1, wherein the recommendation is a file.

4. The method of claim 1, wherein the query is based on context information or content information that was extracted from at least one of user information included in an email, title information included in the email, information in a body of the email, and an attachment of the email.

5. The method of claim 4, wherein the generated recommendation indicates, as storage candidates of the attachment of the email, storage locations corresponding to the context of the user and the contents of the query.

6. The method of claim 4, wherein the generated recommendation indicates, as candidates for an attachment to the email, files corresponding to the context of the user and the contents of the query.

7. The method of claim 1, wherein the collection of digital content items is stored on a plurality of computing devices in an enterprise.

8. The method of claim 1, wherein the context of the user includes a context of a user'"'"'s activity.

9. The method of claim 1, further comprising:

filtering the generated recommendation based on access permissions of the received query.

10. A system for contextual management, the system comprising:

one or more computer-readable media;

one or more input/output interfaces; and

one or more processors that are configured to cause the system to

perform a first process repeatedly, wherein the first process includes;

(i) extracting content information corresponding to a new or modified content item from a collection of digital content items,

(ii) normalizing the new or modified content item corresponding to the extracted content information,

(iii) sending the normalized content item to a data warehouse, which is a local storage for managing a normalized content item, and

(iv) registering keywords extracted from the new or modified content item to the data warehouse;

perform a second process repeatedly, wherein the second process includes;

(i) examining a new content item of the data warehouse,

(ii) generating an index from content information of the new content item, and

(iii) updating an index database using the generated index;

receive a query from a computing device, wherein the query is automatically generated by a client program of the computing device in response to a user'"'"'s operations for an application;

determine a context of the user associated with the received query;

generate an enhanced query by using a registered keyword corresponding to the contents of the query according to the reception of the query;

perform a search based on the context of the user and contents of the enhanced query generated by using the registered keyword;

generate a recommendation according to a result of the search and an index in the index database; and

return the generated recommendation to the client program of the computing device.

11. The system of claim 10, wherein the one or more processors are further configured to cause the system to

crawl a local file system on the computing device, wherein crawling includes identifying recently-accessed documents and directories;

retrieve context information from recently-accessed document and directories;

store retrieved context information in a cache; and

generate the recommendation further according to the context information in the cache.

12. The system of claim 10, wherein the one or more processors are further configured to cause the system to

crawl an enterprise storage location to identify newly-added content items, recently-accessed content items, or recently-revised content items;

and

generate the recommendation further according to the newly-added content items, the recently-accessed content items, or the recently-revised content items.

13. The system of claim 10, wherein the query is based on context information or content information that was extracted from at least one of user information included in an email, title information included in the email, information in a body of the email, and an attachment of the email.

14. The system of claim 10, wherein the generated recommendation indicates candidate storage locations corresponding to the context of the user and the contents of the enhanced query.

15. The system of claim 14, wherein the generated recommendation indicates candidate files corresponding to the context of the user and the contents of the enhanced query.

16. One or more computer-readable storage media storing instructions that, when executed by one or more computing devices, cause the one or more computing devices to perform operations comprising:

performing a first process repeatedly, wherein the first process includes;

(i)extracting content information corresponding to a new or modified content item from a collection of digital content items to be distributed in a plurality of locations on a network,

(ii) normalizing the new or modified content item corresponding to the extracted content information,

(iii) sending the normalized content item to a data warehouse, which is a local storage for managing a normalized content item, and

(iv) registering keywords extracted from the new or modified content item to the data warehouse;

performing a second process repeatedly, wherein the second process includes;

(i) examining a new content item of the data warehouse,

(ii) generating an index from content information of the new content item, and

(iii) updating an index database using the generated index,

receiving a query from computing device, wherein the query is automatically generated by a client program of the computing device in response to a user'"'"'s operation of an application;

determining a context of the user associated with the received query;

generating an enhanced query by using a registered keyword corresponding to the contents of the query according to the reception of the query;

performing a search based on the context of the user and contents of the enhanced query generated by using the registered keyword;

returning the generated recommendation to the client program of the computing device.

17. The one or more computer-readable storage media of claim 16, wherein the recommendation is a file, and

wherein the operations further include determining if a recipient of an email can access the file, and

adding a link to the file instead of adding the file to the email if the recipient can access the file or adding the file to the email if the recipient cannot access the file.
