1. A method for operating a user interface of a machine comprising at least one processor, the method comprising: identifying, by the at least one processor, a plurality of tokens in a targeted text listing; filtering, by the at least one processor, a first token of the plurality of tokens according to a first set of exclusion rules, whereby the first token is excluded as an instance of a similar spelling error if it satisfies any rule of the first set of exclusion rules; when the first token has not been excluded as an instance of a similar spelling error according to the first set of exclusion rules, determining, by the at least one processor, whether a second token of the plurality of tokens is similar to the first token based on a predetermined number of different characters between the first token and the second token; when the first token and the second token are similar, filtering, by the at least one processor, the first token and the second token according to a second set of exclusion rules, whereby the first token is excluded as an instance of a similar spelling error if it satisfies any rule of the second set of exclusion rules; when the first token has not been excluded as an instance of a similar spelling error according to the second set of exclusion rules, identifying, by the at least one processor, the first token as an instance of a similar spelling error based on the second token; and providing, by the at least one processor to the user interface, the similar spelling error instance including the first token and the second token.
