Abstract

A dictionary system has a vendor computer and a plurality of client computers that communicate through the Internet. Each client computer has a word processor program with a spelling checker that utilizes a local main dictionary provided by the vendor and a local customized dictionary containing words added by the user. The vendor computer contains a dictionary of approved words, a database of misspelled words, and a database of requested words. When a user adds a new word to the local customized dictionary, an Internet request is sent to the vendor computer to add the new word to the dictionary of approved words. The user is notified by an Internet message from the vendor computer if the requested word is misspelled. The database of requested words from all users is reviewed periodically and utilized to update the approved dictionary. The updated dictionary is periodically released to the users as an upgrade to the local main dictionary. Users are compensated for the words that they contribute to the approved dictionary.

Claims

1. A dictionary system for spelling checkers and word processing applications, said dictionary system comprising:

a first computer comprising;

a first display mechanism;

a first input mechanism;

a first port mechanism for exchanging information between said first computer and other computers; and

a first memory containing a spelling checking program for checking the spelling in computer text being processed by said first computer, and further containing a first database of words for use with said spelling checking program, such that said spelling checking program causes said first computer to compare a word in computer text with words in said first database, and enables a user to add said word to said first database by means of said first display mechanism and first input mechanism, and further causes said first computer to transmit said word through a communication mechanism to a second computer;

said second computer comprising;

a second port mechanism for exchanging information between said second computer and other computers; and

a second memory-containing a second database of words, and further containing a dictionary program which causes said second computer to receive said word transmitted from said first computer, and to compare said word with words in said second database, and enables said user to request the addition of said word to said second database by means of said first display mechanism and first input mechanism; and

said communication mechanism communicative with said first port mechanism and said second port mechanism, for exchanging information between said first computer and said second computer;

wherein said first database comprises a main dictionary and a supplemental dictionary, such that, following said comparison of said word in computer text with words in said main dictionary and said supplemental dictionary, if said word is not contained in said dictionaries, said spelling checking program causes said first computer to exhibit said word by means of said first display mechanism and enables said user to add said word to said supplemental dictionary by means of said first input mechanism, and to transmit said added word to said second computer.

2. A dictionary system as recited in claim 1, wherein said second database comprises a first dictionary of correctly spelled words and a second dictionary of misspelled words, such that, said dictionary program causes said second computer to compare said transmitted added word with words in said first dictionary and determine if said word is contained in said first dictionary.

3. A dictionary system as recited in claim 2, such that if said word is not contained in said first dictionary, said dictionary program causes said second computer to compare said word with words in said second dictionary, and if said word is contained in said second dictionary, said dictionary program further causes said second computer to send information to said first computer indicating that said word is misspelled.

4. A dictionary system as recited in claim 2, wherein said second database further comprises a third dictionary of words that are requested for addition to said first dictionary, such that, following said second computer receiving said added word, if said word is not contained in said first and second dictionaries, said dictionary program causes said second computer to add said word to said third dictionary.

5. A dictionary system as recited in claim 4, wherein said third dictionary further contains, for each of said requested words, a variable indicating the number of requests for said word, and wherein said dictionary program, upon each addition of a word which is already contained in said third dictionary, changes the value of said variable, and upon each addition of a word which is not already contained in said third dictionary, sets said variable to the value corresponding to one request.

6. A dictionary system as recited in claim 4, wherein said second computer further comprises:

a second display mechanism; and

a second input mechanism;

and wherein said dictionary program further causes said second computer to exhibit each of said words in said third dictionary by means of said second display mechanism and enables a second user of said second computer to transfer any of said words to said first dictionary or second dictionary from said third dictionary by means of said second input mechanism.

7. A dictionary system as recited in claim 6, wherein said third dictionary further contains, for each of said requested words, a variable indicating the number of requests for said word, and wherein said dictionary program further enables a second user of said second computer to retain said word in said third dictionary, and upon such retention sets said variable to the value corresponding to one request.

8. A dictionary system as recited in claim 4, wherein prior to adding said word to said third dictionary, said dictionary program causes said second computer to transmit to said first computer information that said word is not in said first and second dictionaries, and further, wherein said spelling checking program displays said information by means of said first display and enables said user to request the addition to said third dictionary of said word by means of said first input mechanism, and transmits said request to said second computer.

9. A dictionary system as recited in claim 2, such that upon said comparison, if said word is contained in said first dictionary, said dictionary program causes said second computer to transmit to said first computer information regarding said first dictionary.

10. A dictionary system as recited in claim 1, wherein said second computer further comprises:

a second display mechanism; and

a second input mechanism;

and wherein said dictionary program further causes said second computer to exhibit on said second display mechanism each of said words requested by said user for addition to said second database, and enables a second user of said second computer to transfer any of said words to said second database by means of said second input mechanism.

11. A dictionary system as recited in claim 1, wherein said communication mechanism comprises a wide area network communication mechanism.

12. A dictionary system as recited in claim 1, further comprising a plurality of additional computers, each of said additional computers comprising:

an additional memory;

an additional display mechanism;

an additional input mechanism; and

an additional port mechanism for exchanging information between said additional computer and other computers;
