识别器的主要思想主要是对输入字符串的分析，把以空格为分隔符的字符串识别成单个单词。再进行单词词义匹配，就是把单词和预先定义好的基础单词表进行对比，如果能找到相匹配的词义，即对应的单词数字，则按序将这些以阿拉伯数字输出，如果匹配失败，则将原单词字符原样输出，非法字符忽略输出。-Identifier of the main ideas is the analysis of the input string to a space delimited string for identification into a single word. Another word meaning matching, is to pre-defined words and word forms a good basis for comparison, if we can find a matching word, that word corresponding figures, while those with Arabic numerals in sequence output, if the match fails, it will word characters as the original output, illegal characters ignore output.
