European language processing machine with a spelling correction function

Claim 2

Claim 6

The apparatus as claimed in claim 3, wherein said dictionary means includes a user's dictionary so that when a new character is added to the character string to form a new character string, and the new character string is not in the main dictionary, said control apparatus can judge and output the new character string by additionally using the user's dictionary.

Claim 7

A word processing apparatus equipped with a spelling correction portion, comprising: input means for inputting character information; memory means, operatively connected to said input means for storing the character information inputted by said input means; a control apparatus operatively connected to said memory means; and dictionary means, operatively connected to said memory means, for storing a main dictionary and a probability table indicative of a relationship between two arbitrary characters and a frequency of appearance thereof as neighboring characters; said control apparatus including, character string discrimination means for judging whether a character string stored in said memory means is contained in said main dictionary, output means for outputting the character string, when the character string discrimination means judges that character string is contained in the main dictionary, and character addition and discrimination means responsive to the character string discrimination means for selecting a correct word for outputting by adding one character at a time into a character string containing an error, the added character being selected based on a highest frequency of appearance order established in said probability table until a character string with the added character is identified as being contained in said main dictionary, and upon being identified as being contained in said main dictionary, said character string with added character is then outputted by said output means, wherein said probability table includes the letters of the alphabet, A to Z, listed in sequence in a vertical row and a horizontal row so that the frequency of appearance is the intersection of specific letters from each row.
