Spacy/scispacy annotations

Hello, I have never before used Python and I am writing my thesis. I have an ontology of different ancestry terms in the OWL format and my corpus are abstracts from scientific articles. I have been told to use a library in Python called scispacy to annotate those corpus based on the list of ancestry terms I have. The module of spacy is ┬┤phrasematcher`. How can i do this in Python ?
