Abstract

A web-based system for visual construction of logical rules includes a server, a network, and client operatively connected to the server via the network. The server includes a database and a search engine. The client includes a web-based visual rule building application including selectable windows for displaying and visually editing terms, logical operators, logical rules for storage in the database. The logical rules are generated by visually selecting at least one of the terms and logical operators from the windows. The server may further include a search engine configured to perform at least one of a direct search or a contextual search for an entered query string in records stored in the database and the client may include a visual interface for displaying results of the searches. The search results generated by the search engine may be stored as terms in the database for subsequent rule generation.

Claims

1. A system for searching one or more electronic records and displaying relevant data based on the search, the system comprising:

a processor; and

one or more non-transitory program storage devices readable by the processor, tangibly embodying a searching unit, a visual interface and a statistical analyzer executable by the processor,

wherein the searching unit is configured to search for text in the one or more electronic records that are within a context of an entered query string, wherein the context is influenced by text that precedes or follows an instance of the entered query string in the one or more electronic records wherein a context type describes a structure in which the instance of the entered query string may be presented in the one or more electronic records, wherein the context type comprises at least a phrasal context, a bullet context, or a list context,

wherein the statistical analyzer is configured to analyze results of the search, provide search statistics, and order the results associated with the entered query string based on the search statistics and the context of the entered query string, and

wherein the visual interface is configured to display the search statistics and the results of the search presented in the structure corresponding to the context type.

2. The system of claim 1, wherein the text is determined to be within the context of the entered query string when it precedes or follows the instance of the entered query string up to a terminal character.

3. The system of claim 1, wherein the system is configured to search for strings in the one or more electronic records that are also within a context of a string related to the entered query string, wherein the related string is one of a synonym, hypernym, hyponym, inflection, or part of the query string.

4. The system of the claim 2, wherein the terminal character comprises one of punctuation, a bullet, or a space.

5. The system of claim 1, wherein the one or more electronic records comprise one of a medical, financial, or legal record.

6. The system of claim 1, wherein the system is further configured to suppress display of personal information of a patient from the results of the search.

7. The system of claim 1, wherein the statistics correspond to a frequency of occurrence for each of the results.

8. The system of claim 1, wherein the context type comprises a list context that returns a list as the results of the search.

9. The system of claim 1, wherein the searching unit is further configured to perform off-line indexing of text reports from multiple patient databases.

10. The system of claim 1, wherein the statistics relate to a type or institution of the electronic record.

11. The system of claim 1, wherein the searching unit is further configured to narrow its search based on one or more constraints relating to a medical record type or a medical institution.

12. The system of claim 1, wherein the system is further configured to filter the results of the search at different levels, wherein the levels include at least a patient level, a visit level, a physician/nurse level, or a patient group level.

13. The system of claim 1, wherein the system is further configured to derive logical rules from the results of the search to perform more refined data mining.

14. The system of claim 1, wherein the system is further configured to combine the results of the search based on co-occurrence statistics.

15. A method for searching one or more electronic records and displaying relevant data based on the search, the method comprising:

searching, by a computer, for text in the one or more electronic records that are within a context of an entered query string, wherein the context is influenced by text that precedes or follows an instance of the entered query string in the one or more electronic records, wherein a context type describes a structure in which the instance of the entered query string may be presented in the one or more electronic records, wherein the context type comprises at least a phrasal context, a bullet context, or a list context;

calculating, by the computer, search statistics based on results of the search and ordering the results associated with the entered query string based on the search statistics and the context of the entered query string; and

displaying, by the computer, the search statistics and the results of the search presented in the structure corresponding to the context type.

16. The system of claim 15, wherein the text is determined to be within the context of the entered query string when it precedes or follows the instance of the entered query string up to a terminal character.

17. The method of claim 16, wherein the terminal character comprises one of punctuation, a bullet, or a space.

18. The method of claim 15, wherein the statistics correspond to a frequency of occurrence for each of the results.

19. The method of claim 15 further comprises suppressing display of personal information of a patient from the results of the search.
