Abstract

The method and system of the present invention provides for a knowledge management and archival system on a network. A document to be archived is prepared as a machine readable and loaded to a database. The document can be text, image, video or audio, all of which are indexed during and/or after uploading, and stored to the database. This knowledge management system for comprises a server for uploading a record, a user terminal for creating a plurality of indices for each uploaded record; and, a search engine for locating records in response to an index sensitive inquiry. The knowledge management system can also include indexes, such as a field index, a native index and a content index. The knowledge management system also comprises an application program comprising a system administration utility, a data loading component and database management utilities.

Claims

1. A computer-implementable document management method, comprising:

uploading a plurality of documents to a database, wherein the uploaded documents are machine-readable and comprise one or more of text data, image data, video data, and audio data;

assigning the uploaded documents to a hierarchical organizational structure within the database;

indexing the uploaded documents to create a plurality of index fields for each of the uploaded documents;

relating the index fields of the uploaded documents across the hierarchical organizational structure;

receiving a search query having at least one search criterion for at least one of the index fields;

searching the hierarchical organizational structure based on the search query;

retrieving one or more of the uploaded documents across the hierarchical organizational structure of the database based on the search; and

making one or more retrieved documents available to a user.

2. The method of claim 1, wherein the act of indexing the uploaded documents comprises creating at least one user-defined index field.

3. The method of claim 1, wherein the act of indexing the uploaded documents comprises creating at least one content index field having data contained in the uploaded document.

4. The method of claim 3, wherein the act of creating the at least one content index field having data contained in the uploaded document comprises capturing the data from the uploaded document to populate the at least one content index field when uploading the document.

5. The method of claim 4, wherein the act of capturing the data comprises receiving screen capture or document area highlighting from a user using a browser.

6. The method of claim 1, wherein the hierarchical organizational structure comprises a first level having a plurality of projects, a second level having a plurality of parent objects associated with the projects of the first level, and a third level having a plurality of child records associated with the parent objects of the second level.

7. The method of claim 6, wherein the parent objects represent an organizational level of the hierarchical organizational structure, and wherein the parent objects include subject information for linking to the uploaded documents and other information in the database associated with the parent object.

8. The method of claim 6, wherein the act of assigning the uploaded documents to the hierarchical organizational structure within the database comprises assigning one or more of the uploaded documents as one or more of the child records in the hierarchical organizational structure.

9. The method of claim 6, wherein the act of searching the database based on the search query further comprises:

associating the search query with one of the parent objects;

generating a search report based on the search query, and

storing the search report as one of the child records for the parent object associated with the search query.

10. The method of claim 1, further comprising:

defining access restrictions for one or more users; and

restricting access by one of the users to the hierarchical organizational structure of the database based on the access restriction for the user.

11. The method of claim 10, wherein the act of restricting access includes restricting access by the user to information selected from the group consisting of an uploaded document, portion of an uploaded document, an index field, and a portion of an index field.

12. The method of claim 10, wherein the act of retrieving the one or more uploaded documents comprises redacting information from one of the uploaded documents retrieved for a user based on the access restriction defined for the user.

13. The method of claim 1, further comprising:

automatically issuing a notification for a user when a predefined action occurs with respect to an uploaded document.

14. The method of claim 13, wherein the predefined action for the notification is selected from the group consisting of an upload of a predefined document, a completion of indexing of a document, an availability of a document, and a current use of a document.

15. The method of claim 1, further comprising assigning tasks to be performed on document data as documents are uploaded to the database.

16. The method of claim 1, wherein the act of searching the hierarchical organizational structure based on the search query comprises searching the at least one index and one or more other indices related to the at least one index for the at least one search criterion.

17. The method of claim 1, further comprising receiving user selection of a data field within the uploaded documents, and determining a trend analysis for the selected data field.

18. A programmable storage device comprising machine-readable instructions stored thereon for causing a programmable control device to perform a method according to any one of claims 1 through 17.

19. A document management system, comprising:

a database configured with a hierarchical organizational structure,

a server communicatively connected to the database and configured to;

upload a plurality of documents to a database, wherein the documents are machine-readable and comprise one or more of text data, image data, video data, and audio data,

assign the uploaded documents to a hierarchical organizational structure within the database;

index the uploaded documents to create a plurality of index fields for each of the uploaded documents;

relate the index fields of the uploaded documents across the hierarchical organizational structure;

receive a search query having at least one search criterion for at least one of the index fields;

search the hierarchical organizational structure based on the search query;

retrieve one or more of the uploaded documents across the hierarchical organizational structure of the database based on the search; and

make the retrieved documents available to a user.
