AUTOMATIC SUPPLEMENTATION OF WORD CORRECTION DICTIONARIES

Methods and systems for providing a supplemental word correction dictionary are provided. The method is performed at one or more electronic devices each having one or more processors and memory storing one or more programs for execution by the one or more processors. The method includes receiving an at least partial word input by a user. In some implementations, the at least partial word is input into a text field, such as an email body. The method includes determining that a use condition of the at least partial word is satisfied, such as whether the word appears in a trigger word list. The method further includes, in response to determining that the use condition is satisfied, obtaining a supplemental word correction dictionary that includes words associated with a same subject matter as the at least partial word, wherein the supplemental word correction dictionary supplements an existing word correction dictionary.
