Authors's name are currently processed to removed strings that are not actual name, that list is empirical and based on https://github.com/Impactstory/depsy/blob/59a62d6c5fda09f5d390be2b81bc886e79ba63f1/models/byline.py#L21
We saw some others common patterns, thoses should be added the the filtering list
See #376
