System for converting medical information into representative abbreviated codes with correction capability
First Claim
1. A method of coding data representing diagnoses and/or operations which is carried out by a computer in which representative codes are assigned to said data comprising the steps of:
- i) inputting said data to said computer,ii) dividing said data into sub-parts, each said sub-part being of a particular sub-part type,iii) preliminarily grouping said sub-parts into sub-groups by introducing divisions between some sub-parts in said data, each sub-part in a particular sub-group sharing an association with all other sub-parts in said particular sub-group,iv) examining each said sub-group for completeness in regard to each sub-group containing a predetermined distribution of sub-part types,v) if the examination of step (iv) reveals that the sub-group is not complete, completing said sub-groups by amending the constituent sub-parts so that each sub-group contains said predetermined distribution of sub-part types, andvi) outputting said completed sub-groups as coded data for later interrogation or analysis.

Abstract
The present invention relates to a system for coding data. An example implementation is disclosed whereby the coding system is a computer program especially suited to analysing text input to the computer by for example a keyboard, optical character recognition or voice recognition. The data to be coded may, for example, comprise information relating to an event, item or operation. In the preferred form of the invention, the input data is text describing a medical diagnosis and operation which would be dictated or recorded by a surgeon subsequent to an operation being performed on a patient. The coding system of the present invention analyses each word or term of the medical information in conjunction with specialised and generalised dictionaries of words and terms, along with the relationships between individual words or terms. In this way, in addition to producing a compressed symbolic representation of the original information which may later be interrogated or used for statistical analysis, the present invention is also capable of correcting or supplementing the original information.

12. A computer programmed to analyze input data describing an event, item or operation and produce coded output to represent said input data and also attempts to correct deficiencies in said data, said program comprising:
-
i) means for inputting said data to said computer, ii) means for dividing said input data into sub-parts, each said sub-part being of a particular sub-part type, iii) means for preliminarily grouping said sub-parts into sub-groups by introducing divisions between some sub-parts in said data, each sub-part in a particular sub-group sharing an association with all other sub-parts in said particular sub-group, iv) means for checking each said sub-group for completeness in regard to each sub-group containing a predetermined distribution of sub-part types, v) means for determining if the means for checking reveals that the sub-group is not complete, and if not complete, for attempting to complete said sub-groups so that each sub-group contains said predetermined distribution of sub-part types by analyzing said sub-groups in relation to each other and carrying out completion operations on said sub-parts and sub-groups, and vi) means for outputting said completed sub-groups as coded data for later interrogation or analysis. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
