Abstract

An information management, retrieval and display system searches through an informational resource, such as a document (e.g., a treaty), a number of individual documents (e.g., Web pages resident on the Internet), or a stream of information (e.g., DNA code, source code, satellite data transmissions, etc.) and displays the results of the search in an collapsible/expandable format based upon a user-selected display criteria or hierarchy. Such a display hierarchy will allow the end-user to effectively and quickly obtain items of interest from the search results. Generally, the system performs a method for retrieving information from an informational resource that includes the steps of: (a) dividing the informational resource into a plurality of finite elements; (b) assigning a categorical tag to each of the plurality of finite elements, where the categorical tag includes data pertaining to a content of the finite element; (c) generating a searchable database record for each of the plurality of finite elements, where each searchable database record includes at least one string contained within the finite element, where the string can be a word, a phrase, a symbol, a group of symbols, a data segment or the like; (d) supplying a search string; (e) searching the searchable database for searchable database records containing the search string; (f) arranging the results of the searching step in a hierarchal structure according, at least in part, to the data in the categorical tags assigned to the finite elements found in the searching step; and (g) displaying the results of the searching step in the hierarchal structure.

(b) assigning a categorical tag to each of the plurality of finite elements, the categorical tag including data pertaining to a content of the finite element, the assigning step (b) being performed by an expert system according to a second rule set;

(c) generating a searchable database record for each of the plurality of finite elements, each searchable database record including at least one string contained within the finite element;

(d) supplying a search string;

(e) searching the searchable database for searchable database records containing the search string so as to provide search results;

(f) arranging the results of the searching step in a hierarchal structure according to the information in the categorical tags assigned to the finite elements corresponding to the searchable database records found in the searching step;

(g) displaying the results of the searching step in the hierarchal structures;

(h) modifying at least one of the first and second rule sets, responsive to viewing, by an expert having expert knowledge regarding content and structure of the informational resource, unsatisfactory results in the displaying step (g); and

(i) repeating steps (a) through (h) until the expert views satisfactory results in the displaying step (g).

4. The method of claim 1, wherein the informational resource is a plurality of documents and the step of dividing the informational resource into a plurality of finite elements includes the step of identifying the plurality of documents and identifying sections within the plurality of documents, wherein each finite element an identified section.

5. The method of claim 4, wherein the identified section is an entire one of the plurality of documents.

6. The method of claim 1, wherein the informational resource is a data stream and the step of dividing the informational resource into a plurality of finite elements includes the step of identifying segments within the data stream.

7. The method of claim 1, wherein the categorical tag includes data pertaining to an organizational attribute of the finite element with respect to the informational resource.

8. The method of claim 1, wherein the categorical tag includes data pertaining to the location of the finite element.

9. The method of claim 1, wherein the categorical tag includes a categorical phrase pertaining to the content of the finite element.

10. The method of claim 1, wherein the categorical tag includes a categorical number pertaining to the content of the finite element.

11. The method of claim 10, wherein the categorical number is based upon a categorical referencing system analogous to the Dewey decimal system.

12. The method of claim 1, wherein the step of dividing the informational resource into a plurality of finite elements includes the step of identifying and distinguishing between headings and sub-headings within the informational resource.

13. The method of claim 1, wherein each database record further includes an address or link to the corresponding finite element.

14. The method of claim 1, wherein the database record includes non-common strings contained within the finite element.

15. The method of claim 14, wherein:

the informational resource is at least one document;

the database record includes non-common words contained within the finite element; and

the step of supplying a search string involves a step of assigning at least one search word.

16. The method of claim 15 wherein each database record further includes word frequency data pertaining to the frequency of the non-common words contained within the corresponding finite element.

17. The method of claim 16 wherein a hierarchal structure is a collapsible/expandable hierarchy, having at least two levels and the arranging step (f) involves the step of ordering the results of the searching step according to a first one of the levels and then further ordering the results of the searching step according to a next one of the levels.

18. The method of claim 17, wherein at least one of the levels of the hierarchal structure is ordered based upon the data included in the categorical tags assigned to the finite elements that are associated with the database records found in the searching step (e).
