Claims
- 1. A method of ranking results from a free-text query of a document repository, comprising:
generating a set of relevance ranking parameters characterizing document areas in text documents of a document repository; producing results from a free-text query of said document repository; and ranking said results in accordance with said relevance ranking parameters.
- 2. The method of claim 1 wherein generating includes defining a scoring region.
- 3. The method of claim 2 wherein generating includes defining a scoring region in a semi-structured text document.
- 4. The method of claim 3 wherein generating includes defining a scoring region as a tag delimited region of an XML document.
- 5. The method of claim 1 wherein generating includes generating a proximity score relevance ranking parameter that characterizes word distance between matching search terms.
- 6. The method of claim 5 wherein generating includes generating a harmonic mean proximity score relevance ranking parameter.
- 7. The method of claim 1 wherein generating includes generating a matching term frequency score relevance ranking parameter characterizing the number of times a specified search term appears in a document.
- 8. The method of claim 7 wherein generating includes generating an absolute frequency matching term frequency score.
- 9. The method of claim 7 wherein generating includes generating a relative frequency matching term frequency score.
- 10. The method of claim 7 wherein generating includes generating a normalized frequency matching frequency score.
- 11. The method of claim 1 wherein generating includes generating relevance ranking parameters in accordance with adjusted weight criteria.
- 12. The method of claim 1 wherein producing includes performing a free-text query against a word index specifying word locations in documents of said document repository.
- 13. A computer readable medium, comprising:
executable instructions to:
generate a set of relevance ranking parameters characterizing document areas in
text documents of a document repository; produce results from a free-text query of said document repository; and rank said results in accordance with said relevance ranking parameters.
- 14. The computer readable medium of claim 13 wherein said executable instructions to generate a set of relevance ranking parameters include executable instructions to define a scoring region.
- 15. The computer readable medium of claim 14 wherein said executable instructions to generate a set of relevance ranking parameters include executable instructions to define a scoring region in a semi-structured text document.
- 16. The computer readable medium of claim 15 wherein said executable instructions to generate a set of relevance ranking parameters include executable instructions to define a scoring region as a tag delimited region of an XML document.
- 17. The computer readable medium of claim 13 wherein said executable instructions to generate a set of relevance ranking parameters include executable instructions to generate a proximity score relevance ranking parameter that characterizes word distance between matching search terms.
- 18. The computer readable medium of claim 17 wherein said executable instructions to generate a set of relevance ranking parameters include executable instructions to generate a harmonic mean proximity score relevance ranking parameter.
- 19. The computer readable medium of claim 13 wherein said executable instructions to generate a set of relevance ranking parameters include executable instructions to generate a matching term frequency score relevance ranking parameter characterizing the number of times a specified search term appears in a document.
- 20. The computer readable medium of claim 19 wherein said executable instructions to generate a set of relevance ranking parameters include executable instructions to generate an absolute frequency matching term frequency score.
- 21. The computer readable medium of claim 13 wherein said executable instructions to generate a set of relevance ranking parameters include executable instructions to generate a relative frequency matching term frequency score.
- 22. The computer readable medium of claim 13 wherein said executable instructions to generate a set of relevance ranking parameters include executable instructions to generate a normalized frequency matching frequency score.
- 23. The computer readable medium of claim 13 wherein said executable instructions to generate a set of relevance ranking parameters include executable instructions to generate relevance ranking parameters in accordance with adjusted weight criteria.
- 24. The computer readable medium of claim 13 wherein said executable instructions to rank said results include executable instructions to perform a free-text query against a word index specifying word locations in documents of said document repository.
