    • Automatically detecting a misspelled word and replacing the misspelled word with a correctly spelled word. Words are automatically spell checked as delimited. If a word is detected as a misspelled word then a correctly spelled alternate word is generated. The misspelled word and the correctly spelled alternate word are compared according to a set of difference criteria. The difference criteria correspond to common types of misspellings. If the misspelled word and the correctly spelled alternate word differ according to a difference criterion then the correctly spelled alternate word is identified as a replacement candidate word. The results of the difference criteria comparisons are reviewed using a set of selection criteria. If the results of the difference criteria comparisons satisfy the selection criteria then one of the replacement candidate words is correctly spelled as a replacement word and the misspelled word is replaced by the replacement word.
    • 自动检测拼写错误的单词并用拼写错误的单词替换拼写错误的单词。 词被自动拼写检查为分隔符。 如果一个单词被检测为拼写错误的单词,则会生成一个正确拼写的备用单词。 根据一组差异标准比较拼写错误的单词和正确拼写的替代单词。 差异标准对应于常见类型的拼写错误。 如果拼写错误的单词和正确拼写的替代单词根据差异标准而不同,则将正确拼写的替代单词识别为替换候选词。 使用一组选择标准审查差异标准比较的结果。 如果差分标准比较的结果满足选择标准,则替换候选词中的一个被正确拼写为替换字,并且拼写错误的单词被替换词替代。
