Abstract

Document classification systems are valuable tools for searching and retrieving classified documents but can be prohibitively complex and cumbersome for users.

A system for the indexing and retrieval of classified documents inserts keywords, titles or definitions of previously applied classifications into the document record and provides the resulting record to a search engine. Searchers are able to retrieve documents by searching on keywords from the classification system without looking up class coding.

Claims

1. A system for the indexing and retrieval of classified documents, the system comprising, at least one server computer, at least one document collection, said document collection comprising at least one document(s), said document(s) having been classified according to a predefined classification scheme, said predefined classification scheme comprising classification codes, said classification codes comprising title(s) and definition(s);

at least one server web application; and

at least one search engine system;

wherein said server computer is connected to said search engine, and wherein said server web application communicates document(s) from said document collection to said search engine;

wherein at least one word from at least one of classification code title(s) or classification code definition(s) is inserted within said document(s) to create augmented document(s); and

wherein said augmented documents are indexed by said system for subsequent retrieval.

2. The system for the indexing and retrieval of classified documents of claim 1, wherein the document(s) is in a format, said format selected from the group consisting of:

HTML, XML, PDF, and MSWord.

3. The system for the indexing and retrieval of classified documents of claim 1, wherein the document(s) is in a first language, and wherein at least one of the classification code title(s) or the classification code definition(s) is in a second language.

4. The system for the indexing and retrieval of classified documents of claim 1, wherein the system further comprises:

at least one client computer, wherein said client computer is connected to said server computer.

5. The system for the indexing and retrieval of classified documents of claim 1, wherein the system further comprises:

at least one client computer, wherein said client computer is connected to said server computer, and wherein said tagged document is communicated to said client computer.

6. The system for the indexing and retrieval of classified documents of claim 1, wherein at least one of classification code title(s) or classification code definition(s) is inserted within said document(s) to create augmented document(s).

7. A system for the indexing and retrieval of classified documents, the system comprising, at least one server computer, at least one document collection, said document collection comprising at least one document(s), said document(s) having been classified according to a predefined classification scheme, said predefined classification scheme comprising classification codes, said classification codes comprising title(s) and definition(s), said document(s) further comprising at least one retrieval key, wherein said retrieval key corresponds with at least one term of at least one of said classification code title(s) or classification code definition(s);

at least one server web application; and

at least one search engine system, wherein said server computer is connected to said search engine, and wherein said server web application communicates document(s) from said document collection to said search engine; and

a means for dynamically inserting said term into said document(s) to create a tagged document, wherein said insertion is in response to a request from said search engine, and wherein said tagged document is communicated to said search engine.

8. The system for the indexing and retrieval of classified documents of claim 7, wherein the document(s) is in a format, said format selected from the group consisting of:

HTML, XML, PDF, and MSWord.

9. The system for the indexing and retrieval of classified documents of claim 7, wherein the document(s) is in a first language, and wherein the term is in a second language.

10. The system for the indexing and retrieval of classified documents of claim 7, wherein the system further comprises:

at least one client computer, wherein said client computer is connected to said server computer.

11. A computerized method for the indexing and retrieval of classified documents comprising:

retrieving a document(s) from a document collection, said document(s) having been classified according to a predefined classification scheme, said predefined classification scheme comprising classification codes, said classification codes comprising title(s) and definition(s), wherein said retrieving is in response to a request from a search engine, wherein at least one word from at least one of classification code title(s) or classification code definition(s) is inserted within said document(s)to create augmented document(s), and wherein said augmented document(s) are indexed; and

transmitting said document(s) to said search engine.

12. The computerized method for the indexing and retrieval of classified documents of claim 11, wherein the document(s) is in a format, said format selected from the group consisting of:

HTML, XML, PDF, and MSWord.

13. The computerized method for the indexing and retrieval of classified documents of claim 11, wherein the document(s) is in a first language, and wherein at least one of the classification code title(s) or the classification code definition(s) is in a second language.

14. The computerized method for the indexing and retrieval of classified documents of claim 11, wherein the document collection contains at least one patent document.

15. The computerized method for the indexing and retrieval of classified documents of claim 11, wherein the system further comprises:

at least one client computer, wherein said client computer is connected to said server computer.

16. The computerized method for the indexing and retrieval of classified documents of clam 11, wherein at least one of classification code title(s) or classification code definition(s) is inserted within said document(s) to create augmented document(s).

17. A computerized method for the indexing and retrieval of classified documents comprising:

retrieving a document(s) from a document collection, said document(s) having been classified according to a predefined classification scheme, said predefined classification scheme comprising classification codes, said classification codes comprising title(s) and definition(s), said document(s) further comprising at least one retrieval key, wherein said retrieval key corresponds with at least one term of at least one of said classification code title(s) or said classification code definition(s), wherein said retrieving is in response to a request from a search engine, retrieving from a database at least one keyword derived from at least one of said classification code title(s) or classification code definition(s);

inserting said term into said document(s) to create a tagged document; and

transmitting said tagged document to said search engine.

18. The computerized method for the indexing and retrieval of classified documents of claim 17, wherein the document(s) is in a format, said format selected from the group consisting of:

HTML, XML, PDF, and MSWord.

19. The computerized method for the indexing and retrieval of classified documents of claim 17, wherein the document(s) is in a first language, and wherein the term is in a second language.
