Abstract

A system and a method providing for the distribution and management of a large corpus of value added electronic documents while providing customized services to a plurality of diverse end users.

Claims

1. A system for processing inquiry messages seeking documents comprising:

a. a user interface receiving inquiry messages and corresponding to one or more of a plurality of resource applications running on the system, each resource application associated with a differentiated subscription, the subscription determining a level of value-added content to which the resource application has access;

b. one or more data collections on computer-accessible memory storing documents for delivery to a user in response to an inquiry message;

c. one or more metadata information files on computer-accessible memory holding metadata for documents stored in the one or more data collections;

d. a new document intake component storing content of, and processing, documents that are to be added to the one or more data collections, the intake component using metadata extractors to develop metadata from a new document and to store at least a portion of the metadata in the metadata information files substantially simultaneously with storing the new document as ready for user access in the one or more data collections, the metadata comprising value-added content developed at least in part from the content of the new document as delivered to the new document intake component;

e. a delivery component, responsive to a resource application receiving an inquiry message, delivering, through the corresponding user interface, results documents responsive to the inquiry message wherein the content of the results documents is supplemented with value-added content of the metadata associated with the results documents as determined by the subscription associated with the resource application; and

f. at least one processor for executing the components and accessing the computer-accessible memories.

2. The system of claim 1 wherein the system comprises a table of contents service for maintaining at least one table of contents with a plurality of nodes, one or more of said nodes identifying one or more documents associated with said one or more nodes.

3. The system of claim 2 wherein the table of contents service supports two or more tables of contents, each table of contents being adapted to a particular user type.

4. The system of claim 2 wherein the at least one table of contents references documents that are in two or more data collections.

5. The system of claim 3 wherein one of the two or more tables of contents references a node in another of the two or more tables of contents to define a recursive structure.

6. The system of claim 1 wherein documents in at least one data collection are partitioned into at least one collection subset and the system has an index service that maintains an index of keywords appearing at least once in the collection subset, with an association between the keywords in the index and the location of their appearance in the collection subset.

7. The system of claim 1 wherein documents in at least one data collection are partitioned into at least one collection subset and wherein the new document intake component ensures that each additional document has a unique identifier and is assigned to at least one collection subset.

8. The system of claim 1 wherein the at least one data collection has a least one document set that is an aggregation of the documents in one or more collection subsets.

9. The system of claim 1 wherein the system further comprises a security service component that receives user identification information and inquiry messages and validates the identification information and inquiry messages against user subscription information.

10. The system of claim 1 wherein the metadata extractors process a document to cause association of the document with at least one of the following:

a. additional editorial material prepared by a human agent;

b. additional editorial material prepared by an automated agent;

c. a link providing a pointer to another document in the data collection;

d. citation based metadata to legal or bibliographic documents;

or

e. an entry associated with the document appearing in a metadata file.

11. The system of claim 1 wherein the intake component prioritizes documents and processes out of a normal order based on time of receipt documents bearing a time sensitive indicator.

12. The system of claim 1 wherein the intake component checks the uniqueness of an assigned document identifier before a new document with such document identifier is made available in any data collection.

13. The system of claim 1, wherein the intake component checks a new document for a predetermined intake format before such new document is made available in any data collection.

14. The system of claim 1 wherein the one or more data collections comprise at least 20 terabytes of information.

15. The system of claim 1 wherein the metadata developed from a new document by the intake component includes one or more brand identity attributes.

16. The system of claim 1 wherein the metadata developed from a new document by the intake component includes information for use by the resource application for one or more of overlaying, adding, deleting, and modifying one or more of data, parameters, and display formats for the document.

17. A method for delivering to users that submit inquiry messages inquiry results and documents selected from a large aggregation of electronically stored documents, comprising:

a. providing access to a user interface associated with one or more of a plurality of resource applications running on a computer system for eliciting from a user an inquiry message in electronic form seeking documents stored in electronic form in a data collection on computer-accessible memory, each document having a unique identifier and associated enrichment attributes, the enrichment attributes comprising value-added content developed at least in part from the content of the document, wherein each resource application is associated with a differentiated subscription, the subscription determining a level of value-added content to which the resource application has access;

b. providing for the inquiry message to be delivered to a search component executing on the computer system and shared by the plurality of resource applications for processing the inquiry message to identify documents in the data collection that are responsive and retrieving at least one identifier for documents that are responsive;

c. providing to the user in response to the inquiry message a search result message from the computer system identifying one or more documents;

d. in response to a user message that selects a document from the search result message, delivering the selected document from the computer system through the user interface to the user in a predetermined format, the selected document supplemented with value-added content of the enrichment attributes selected based on at least one of the subscriptions associated with the one or more resource applications associated with the user interface; and

e. associating with the selected document a point-in-time attribute, to permit detection of an updated version of the selected document.

18. A computer program embodied in a computer-readable storage medium for facilitating delivery to users that submit inquiry messages inquiry results and documents selected from a large aggregation of electronically stored documents, comprising:

a code component presenting a user interface associated with a resource application running on a computer system for eliciting from a user an inquiry message in electronic form seeking documents stored in electronic form in a data collection, each document having a unique identifier and associated enrichment attributes, the enrichment attributes comprising value-added content developed at least in part from the content of the document, and the resource application being one of a plurality of resource applications each associated with a differentiated subscription, the subscription determining a level of value-added content to which the resource application has access;

a code component providing the inquiry message to be delivered to a search component shared by the plurality of resource applications for processing the inquiry message to identify documents in the data collection that are responsive and retrieving at least one identifier for documents that are responsive;
