Project Timeline

Timeframe	Task	Completion
Week 4	Finalize and present project proposals. Toponym extraction project selected.	✓
Week 5	Survey SOTA toponym extraction tools.	✓
Week 6	Port MapKurator into Windows-based Python Select two (later four) maps to	✓
Week 7	Create ground truth labels for first map with VIA's online interface.	✓
Week 8	Create ground truth labels for second map. Implement 1:1-matched precision and recall via IoU (geometry) and normalized Levenshtein (text)	✓
Week 9	Implement multi-layer pyramid approach to toponym extraction	✓
Week 10	Create ground truth labels for third map. Implement toponym rectification and amalgamation algorithms.	✓
Week 11	Calculate accuracy statistics for pyramid approach Deliver Midterm presentation.	✓
Week 12	Launch Wiki. Group words into toponyms via polygon size and location. Apply NLP tools to correct toponyms.
Week 13	Create ground truth labels for fourth map. Calculate final accuracy statistics. Hierarchize final toponyms and develop Voronoi map.
