How to improve accuracy of Named entity recognition (NER) tagger on local data? I am using NER from spacy. Its giving incorrect results for few words. Its trained on general dataset. How can I customize on my local data. 

For example,

Person -  {'Mike Miller', 'Miller', 'Infantino', 'Gianni Infantino'}
Location -  {'England', 'UK', 'Europe', 'Telegraph'}


Here, "Telegraph" is incorrectly is assigned to location.
@Ravikm, excellent question. In Spacy, you can assign a word manually. For example, "Tesla" to ORG. Source: screenshot from Jose Portilla's NLP course on Udemy.
