Methodology

Detecting Locations

NER with Spacy

//LIST or visual

So, we can see the problem is mislabeling: in theory we only need to retrieve the toponyms, i.e. “GPE” & “LOC”, but SpaCy labelled some of them as “PERSON” or “ORG”. In other words, if we only select “GPE” and “LOC”, we’ll lose some toponyms; if we also select “ORG” and “PERSON”, we’ll get some non-toponyms.

Difficulties when working with historical content

Too many mis-labels due to historical and biblical references place names changing over time multiple languages

Difficult to understand even by reading sometimes

Importance of understanding how places relate to the meaning in the book
