Abstract

In computerized processing of natural-language medical/clinical data including phrase parsing and regularizing, parameters are referred to whose value can be specified by the user. Thus, a computerized system can be provided with versatility, for the processing of data originating in diverse domains, for example. Further to a parser and a regularizer, the system includes a preprocessor, output filters, and an encoding mechanism.

Claims

1. A computer method for processing medical/clinical data comprising a natural-language phrase,

the method comprising parsing the natural-language phrase and regularizing the parsed phrase,

wherein said parsing step comprises referring to a domain parameter whose value is indicative of a medical/clinical domain from which the data originated, and wherein said domain parameter corresponds to one or more rules of grammar within a knowledge base related to said medical/clinical domain to be applied for parsing said natural language phrase.

2. The method according to claim 1, further comprising preprocessing the data prior to parsing, with preprocessing comprising referring to the domain parameter.

3. The method according to claim 1, further comprising encoding at least one term of the regularized phrase, with encoding comprising referring to the domain parameter.

4. The method according to claim 1, further comprising filtering the regularized phrase.

5. The method according to claim 1, further comprising referring to an additional parameter which is indicative of the degree to which subphrase parsing is to be carried out.

6. The method according to claim 1, further comprising referring to an additional parameter which is indicative of desired filtering.

7. The method according to claim 1, further comprising referring to an additional parameter which is indicative of a desired type of output.

8. The method according to claim 1, further comprising referring to an additional parameter which is indicative of a desired output format.

9. A computer system for processing medical/clinical data comprising a natural-language phrase,

the system comprising means for parsing the natural-language phrase and means for regularizing the parsed phrase,

wherein the said parsing step means comprises means for referring to a domain parameter whose value is indicative of a medical/clinical domain from which the data originated, and wherein said domain parameter corresponds to one or more rules of grammar within knowledge base related to said medical/clinical domain to be applied for parsing said natural language phase.

10. The system according to claim 9, further comprising means for preprocessing the data prior to parsing, with the preprocessing means comprising means for referring to the domain parameter.

11. The system according to claim 9, further comprising means for encoding at least one term of the regularized phrase, with the encoding means comprising means for referring to the domain parameter.

12. The system according to claim 9, further comprising means for filtering the regularized phrase.

13. The system according to claim 9, further comprising means for referring to an additional parameter which is indicative of the degree to which subphrase parsing is to be carried out.

14. The system according to claim 9, further comprising means for referring to an additional parameter which is indicative of desired filtering.

15. The system according to claim 9, further comprising means for referring to an additional parameter which is indicative of a desired type of output.

16. The system according to claim 9, further comprising means for referring to an additional parameter which is indicative of a desired output format.

17. A combination of the system according to claim 9 with an interface module for enabling the system to receive input from and/or to produce standardized output for the World-Wide Web and/or a local network.

18. The combination according to claim 17, further comprising means for viewing the output using a standardized browser.

19. The combination according to claim 18, wherein the browser is a Web-browser.
