Abstract

A multi-user system for text mining a large population of research documents in an efficient and cost-effective fashion includes a content repository, a text mining processor, and a derived data repository that are linked via a user-accessible, central project manager. The content repository includes a data storage device for storing the research documents and a content selection facility for receiving a user-defined query that is able to support cost-related search parameters. The query is utilized by the content selection facility to select an initial collection of documents from the data storage device. Content spread metrics are then displayed through user-intuitive reports to allow for subsequent modification of the search query to yield an optimized document collection. The optimized document collection is then parsed, tagged and clustered by the text mining processor to produce search results that are stored as a data set in the derived data repository.

Claims

1. A system for facilitating the text mining of a plurality of research documents by a user, the plurality of research documents carrying a non-uniform cost for access by the user, the system comprising:

(a) a content repository adapted to store the plurality of research documents, the content repository being adapted to receive a query from the user to select a primary collection of the plurality of research documents for text mining, the content repository providing content spread metrics relating to the research documents in the primary collection that enables the user to optionally modify the query to yield a final collection of the plurality of research documents that is optimized for the user; and

(b) a text mining processor for text mining the final collection of research documents to produce a derived text mining data set.

2. The system as claimed in claim 1 further comprising a project manager for managing text mining of the plurality of research documents, the project manager electronically linking the content repository and the text mining processor.

3. The system as claimed in claim 2 wherein the project manager provides a computer interface for direct access to the system by the user.

4. The system as claimed in claim 3 wherein the content repository executes the query using in compliance with one or more rules relating to the content spread metrics of the research documents to be collected.

5. The system as claimed in claim 4 wherein the content repository generates a report relating to the content spread metrics of the research documents in the primary collection.

6. The system as claimed in claim 5 wherein the report includes at least one display from the group consisting of a list, a pie chart, a line graph and a single value.

7. The system as claimed in claim 4 wherein the content repository comprises:

(a) a data storage device for storing bibliographic metadata and full text for each of the plurality of research documents; and

(b) a content selection facility for receiving and executing the query, the content selection facility being in electronic communication with the data storage device.

8. The system as claimed in claim 7 wherein the data storage device includes a database of user access rights that enables the content repository to determine an access cost for each of the plurality of research documents to the user.

9. The system as claimed in claim 8 wherein the content selection facility is capable of supporting document access cost parameters into the query.

10. The system as claimed in claim 9 wherein the content selection facility utilizes the user access cost for each of the plurality of research documents in the cost parameters for the query.

11. The system as claimed in claim 10 wherein the content selection facility is capable of supporting document access cost parameters into the query that are defined by the user and that are modifiable.

12. The system as claimed in claim 11 wherein the content selection facility is capable of supporting a maximum user access cost into the query.

13. The system as claimed in claim 5 wherein the content repository provides cost-related content spread metrics in the report for the research documents in the primary collection of the research documents.

14. The system as claimed in claim 1 wherein the content selection facility cross-references and stores the final collection of research documents retrieved in response to the query to facility future text mining operations.

15. The system as claimed in claim 1 wherein the text mining processor performs text mining of the final collection of research documents using parallel clusters of similar data structures.

16. The system as claimed in claim 15 wherein the text mining processor includes application programming interfaces for developing both standard and custom text mining processing modules.

17. The system as claimed in claim 1 further comprising a derived data repository in communication with the text mining processor, the derived data repository storing the derived text mining data set.
