Abstract
Abstract A system for proofreading a text document and automatically detecting and replacing text words in the document which exceed a predetermined understandability level for the documents intended audience. Text words and synonyms are stored in a dictionary which includes an understandability code for each word based statistically on textbook grade levels. The operator enters a grade level code into the system for the intended document audience. The system scans the document for words which exceed the desired grade level, highlights those words on the system display and prompts the operator with synonyms which can be used to replace the highlighted word. The operator may select a desired replacement synonym by placing the system cursor underneath the word and depressing and enter key from the system keyboard.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
203 words
A method for detecting and correcting linguistic expressions which exceed a predetermined understandability level in a list of linguistic expressions using a programmable digital computer system comprising the steps of: (a) storing in a first section of the memory of said programmable digital computer system a dictionary of linguistic expressions including an understandability code for each linguistic expression; (b) storing in a second section of the memory of said programmable digital computer system a list of synonymic expressions for said dictionary of linguistic expressions including an understandability code for each synonymic expression; (c) storing a code representing a predetermined desired understandability level; (d) comparing each member of an input set of linguistic expressions to said dictionary of linguistic expressions; (e) comparing the understandability code of the dictionary linguistic expression which compares equal to the input member linguistic expression to the stored desired understandability level code; (f) highlighting the member of the input set of linguistic expressions when the understandability code of the dictionary linguistic expression is greater than the stored desired understandability level code; (g) displaying a set of synonymic expressions for the highlighted linguistic expression; and (h) replacing the highlighted linguistic expression with a member of the displayed set of synonymic expressions.

Claim 7
Independent Claim
195 words
A system for detecting and correcting the understandability level of linguistic expressions in a set of linguistic expressions using an information processor comprising: means for storing a dictionary of linguistic expressions including an understandability code associated with each linguistic expression; means for storing a list of synonymic expressions for said dictionary of linguistic expressions including an understandability code associated with each synonymic expression; means for storing a code representing a predetermined understandability level; first compare means for comparing each member of an input set of linguistic expressions to said dictionary of linguistic expressions; second compare means responsive to said first compare means for comparing the understandability code of the dictionary linguistic expression which compares equal to the member of the input set of linguistic expressions to said code representing a predetermined understandability level; means for highlighting the member of the input set when the understandability code of the dictionary linguistic expression compares greater than the predetermined understandability level; means for displaying the set of synonymic expressions for the highlighted member of the input set of linguistic expressions; and means for replacing the highlighted linguistic expression with a member of the displayed set of synonymic expressions.
Claim 8
Independent Claim
195 words
A system for detecting and correcting the understandability level of linguistic expressions in a set of linguistic expressions using an information processor comprising: means for storing a dictionary of linguistic expressions including an understandability code associated with each linguistic expression; means for storing a list of synonymic expressions for said dictionary of linguistic expressions including an understandability code associated with each synonymic expression; means for storing a code representing a predetermined understandability level; first compare means for comparing each member of an input set of linguistic expressions to said dictionary of linguistic expressions; second compare means responsive to said first compare means for comparing the understandability code of the dictionary linguistic expression which compares equal to the member of the input set of linguistic expressions to said code representing a predetermined understandability level; means for highlighting the member of the input set when the understandability code of the dictionary linguistic expression compares greater than the predetermined understandability level; means for displaying the set of synonymic expressions for the highlighted member of the input set of linguistic expressions; and means for replacing the highlighted linguistic expression with a member of the displayed set of synonymic expressions.
