Abstract

Systems and methods are provided for expressing a body of knowledge in standard or normalized terms. A topic hierarchy comprises topics related to the body of knowledge, with one or more topics comprising subtopics, and with subtopics themselves possibly comprising further subtopics. Principles are found within documents that are related to the body of knowledge, and standard terminology is selected to express those principles. Documents may be associated with the standard expressions corresponding to the respective principles found in the documents, and one or more of the standard expressions may be associated with at least one topic, subtopic, or both.

Claims

1. A method of providing a synopsis of a body of knowledge, comprising:

storing within at least one electronic database a representation of a topic hierarchy that comprises a plurality of topics related to the body of knowledge, at least one topic comprising one or more subtopics, and at least one subtopic further comprising one or more subtopics;

for each of a plurality of documents, at least one of which is a citing document that includes at least one citation to at least one of the plurality of documents, finding at least one statement within the document that expresses a principle related to the body of knowledge;

for each of the principles identified in any one or more of the documents, creating a standard expression of the principle and storing the created expression within the at least one electronic database in relation to at least one of the subtopics and in relation to each of the documents in which the identified principle was expressed.

2. The method of claim 1, wherein each of the standard expressions expresses a rule of law.

3. The method of claim 1, comprising:

finding within a citing document a citation to one other document of the plurality of documents and a statement, associated with the citation, that is substantially equivalent to one of the standard expressions; and

storing the citing document in relation to the other document and in relation to the subtopic that is related to the standard expression.

4. The method of claim 3, comprising providing an indication that the citing document includes the citation to the one other document and an identification of the standard expression.

5. A method of providing a citation index, comprising:

finding within a first document a first expression of a principle;

storing within the at least one database a first association between the first document and a standard expression of the principle;

finding within a second document a second expression of the principle and a citation to the first document, the citation being associated with the second expression of the principle;

storing within the at least one database a second association between the second document and the standard expression of the principle and a third association between the second document and the first document; and

providing an indication that the second document includes the citation to the first document and an identification of the standard expression of the principle.

6. The method of claim 5, comprising:

storing within the at least one database, in association with the standard expression of the principle, information indicating a treatment within the second document of the first expression of the principle; and

providing an indication of the treatment and an identification of the first document.

7. The method of claim 5, comprising storing within the at least one database a fourth association between the standard expression of the principle and a subtopic within a topic hierarchy that comprises a plurality of topics related to a body of knowledge, at least one topic comprising one or more subtopics, and at least one subtopic further comprising one or more subtopics.

8. The method of claim 7, wherein the principle is a rule of law.

9. The method of claim 5, wherein the principle is a rule of law.

10. The method of claim 9, wherein the second document is a judicial opinion.

11. A system for providing a synopsis of a body of knowledge, comprising:

a programmable processor, an input device that provides input to the system, a database, and a memory;

the memory storing instructions that, when executed by the processor, cause the system to carry out a method that comprises

storing within the at least one database a representation of a topic hierarchy that comprises a plurality of topics related to the body of knowledge, at least one topic comprising one or more subtopics, and at least one subtopic further comprising one or more subtopics;

for each of a plurality of documents, receiving first input through the input device designating at least one statement within the document that expresses a principle related to the body of knowledge; and

for each of the principles designated in any one or more of the documents, receiving second input, through the input device, that indicates a standard expression of the principle and, in response to the second input, storing that expression within the at least one database in relation to at least one of the subtopics and in relation to each of the documents in which the principle was expressed.

12. The system of claim 11, wherein each of the standard expressions expresses a rule of law.

13. The system of claim 11, wherein the method comprises:

receiving third input through the input device, designating within a citing document a citation to one of the documents, a statement that is substantially equivalent to one of the stored standard expressions, and an association between the citation and the statement; and

storing the citing document in the at least one database in relation to the cited document and in relation to the subtopic that is related to the standard expression.

14. The system of claim 13, wherein the method comprises providing an indication that the second document includes the citation to the first document and an identification of the standard expression.

15. A system for providing a citation index, comprising:

a programmable processor, an input device that provides input to the system, a database, and a memory;

the memory storing instructions that, when executed by the processor, cause the system to carry out a method that comprises

accepting first input through the input device designating within a first document a first expression of a principle;

storing within the at least one database a standard expression of the principle;

storing within the at least one database a first association between the first document and the standard expression of the principle;

accepting input through the input device designating within a second document a second expression of the principle and a citation to the first document, the citation being associated with the second expression of the principle;

storing within the at least one database a second association between the second document and the standard expression of the principle and a third association between the second document and the first document; and

providing an indication that the second document includes the citation to the first document and an identification of the standard expression of the principle.

16. The system of claim 15,wherein the method comprises:

storing within the at least one database, in association with the standard expression of the principle, information indicating a treatment within the second document of the first expression of the principle; and

providing an indication of the treatment and an identification of the first document.

17. The system of claim 16, wherein the method comprises storing within the at least one database a fourth association between the standard expression of the principle and a subtopic within a topic hierarchy that comprises a plurality of topics related to a body of knowledge, at least one topic comprising one or more subtopics, and at least one subtopic further comprising one or more subtopics.

18. The system of claim 17, wherein the principle is a rule of law.

19. The system of claim 15, wherein the principle is a rule of law.
