Introduction

Delving into the pages of "Hadji in Syria: or, Three years in Jerusalem" by Sarah Barclay Johnson, this project sets out to digitally map the toponyms embedded in Johnson's 19th-century exploration of Jerusalem with the wish to connect the past and the present. By visualizing Johnson's recorded toponyms, this project aims to offer a dynamic tool for scholars and enthusiasts, contributing to the ongoing dialogue on the city's historical evolution.

This spatialization, in its attempt, pays homage to Johnson's literary contribution, serving as a digital window into the cultural crossroads: Jerusalem. The project invites users to engage with the city's history, fostering a deeper understanding of its rich heritage and the interconnected narratives that have shaped the city. In this fusion of literature, history, and technology, we hope to embark on a digital odyssey, weaving a narrative tapestry that transcends time and enriches our collective understanding of Jerusalem's intricate past.

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Difficulties when working with historical content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

Preliminary Analysis for Model Selection - Assessment Focusing on Chapter 3
