Abstract

The present invention improves the comprehensibility of a document being read on a computer system. Rather than requiring a reader to stop and look up the meaning of a word, either on-line or with a printed copy, the present invention will automatically translate unknown words into words known to the reader. By checking each word in a document against a known word list maintained on the computer, the present invention improves the readers comprehension of a document as well as simplifies the reading thereof.

Claims

1. A computer implemented method of teaching a specific individual reader and automatically improving comprehensibility of a document on a computer system for that reader, comprising the steps of:

storing a business thesaurus file in a storage device accessible by the computer system;

storing a list of reader identified known words in said storage device;

associating reader defined parameters with said known words in order to ensure said known words are currently known to the reader;

automatically comparing all words in the document to said list of known words to identify unknown words;

automatically accessing said business thesaurus file to obtain a synonym for each of said unknown words, said synonym also being on said list of known words;

automatically updating said list of known words to remove words that have become not currently known and to add words that have become currently known in accordance with said reader defined parameters; and

automatically displaying the document to the reader with said synonym displayed adjacent each of said unknown words corresponding thereto, wherein the reader learns a meaning of said unknown words and the document is automatically more comprehensible to the reader.

2. The computer implemented method of claim 1, wherein said step of associating comprises the steps of:

assigning a first numerical value to said known words to reflect how many occurrences of a word are required for said word to become a known word; and

assigning a second numerical value to said known words to reflect a period of time of no occurrences after which a known word becomes an unknown word.

3. A computer system for teaching a specific individual reader and automatically improving comprehensibility of a document on the computer system for that reader, comprising:

means for storing a business thesaurus file in a storage device accessible by the computer system;

means for storing list of reader identified known words in said storage device;

means for associating reader defined parameters with said known words in order to ensure said known words are currently known to the reader;

means for automatically comparing all words in the document to said list of known words to identify unknown words;

means for automatically accessing said business thesaurus file to obtain a synonym for each of said unknown words, said synonym also being on said list of known words;

means for automatically updating said list of known words to remove words that have become not currently known and to add words that have become currently known in accordance with said reader defined parameters; and

means for automatically displaying the document to the reader with said synonym displayed adjacent to each of said unknown words corresponding thereto, wherein the reader learns a meaning of said unknown words and the document is automatically more comprehensible to the reader.

4. The computer system of claim 3, wherein said means for associating comprises:

means for assigning a first numerical value to reflect how many occurrences of a word are required for said word to become a known word; and

means for assigning a second numerical value to reflect a period of time of no occurrences after which a known word becomes an unknown word.
