clean_email_mapper

Cleans email addresses from text samples using a regular expression.

This operator removes or replaces email addresses in the text based on a regular expression pattern. By default, it uses a standard pattern to match email addresses, but a custom pattern can be provided. The matched email addresses are replaced with a specified replacement string, which defaults to an empty string. The operation is applied to each text sample in the batch. If no email address is found in a sample, it remains unchanged.

使用正则表达式从文本样本中清理电子邮件地址。

此算子基于正则表达式模式删除或替换文本中的电子邮件地址。默认情况下，它使用标准模式匹配电子邮件地址，但可以提供自定义模式。匹配到的电子邮件地址将被替换为指定的替换字符串，默认为空字符串。该操作应用于批次中的每个文本样本。如果样本中没有找到电子邮件地址，则保持不变。

✨ explanation 解释

This example demonstrates the default behavior of the CleanEmailMapper, which removes email addresses from the text. The operator uses a regular expression to identify and remove any email addresses found in the 'text' field. In the provided samples, emails like 'euqdh@cjqi.com' and 'rdash@hqbchd.ckdhnfes.cds' are removed, leaving only the non-email parts of the text. The sample with no valid email address ('请问你是谁dasoidhao@1264fg.45om') remains unchanged. 这个例子展示了CleanEmailMapper的默认行为，即从文本中移除电子邮件地址。算子使用正则表达式来识别并移除'text'字段中的任何电子邮件地址。在提供的样本中，像'euqdh@cjqi.com'和'rdash@hqbchd.ckdhnfes.cds'这样的电子邮件被移除，只留下文本中的非电子邮件部分。没有有效电子邮件地址的样本（'请问你是谁dasoidhao@1264fg.45om'）保持不变。

✨ explanation 解释

In this case, the CleanEmailMapper is configured to replace email addresses with a specific string '' instead of removing them. The operator identifies email addresses using a regular expression and replaces each found email with the specified replacement string. This way, the original structure of the sentences is maintained, but all email addresses are replaced with ''. For instance, 'euqdh@cjqi.com' is replaced by '', and 'rdash@hqbchd.ckdhnfes.cds' is also replaced by the same string. The sample that does not contain a valid email address remains as it is. 在这种情况下，CleanEmailMapper被配置为用特定字符串''替换电子邮件地址而不是移除它们。算子使用正则表达式识别电子邮件地址，并将每个找到的电子邮件替换为指定的替换字符串。这样，句子的原始结构得以保留，但所有电子邮件地址都被替换成了''。例如，'euqdh@cjqi.com'被替换为''，而'rdash@hqbchd.ckdhnfes.cds'也被替换为相同的字符串。不含有效电子邮件地址的样本保持不变。
