class data_juicer.ops.mapper.clean_copyright_mapper.CleanCopyrightMapper(*args, **kwargs)

基类：Mapper

Cleans copyright comments at the beginning of text samples.

This operator removes copyright comments from the start of text samples. It identifies and strips multiline comments that contain the word "copyright" using a regular expression. It also greedily removes lines starting with comment markers like //, #, or -- at the beginning of the text, as these are often part of copyright headers. The operator processes each sample individually but can handle batches for efficiency.
