You are using ner_crf to extract custom entity username. It won’t be able to capture all of the new names. Based on the story sometimes it will but if you have similar stories, it won’t perform well.
Try using Spacy’s pre-trained PERSON entity, you will be able to capture more names this way. However, It is very difficult to extract person names as there can be millions.
Sorry thanks, for a while I worked on smth else. I read documentation about entity extraction. In my config.yml file. Can I add new_spacy into pipieline ? Can I have both ner_spacy and ner_crt in my pipeline at the same time ?
