Project Plan

Date	Task	Completion
Week 4	Finalize and present project proposals.	✓
Week 5	Survey SOTA toponym extraction tools. Implement MapKurator	✓
Week 6	Grasshopper implementation of Islamic 2D star pattern	✓
Week 7	Find the steps traditionally followed by craftsmen to construct muqarnas.	✓
Week 8	Create ground truth labels for first map. Implement 1:1-matched precision and recall via IoU (geometry) and normalized Levenshtein (text)	✓
Week 9	Create ground truth labels for second map. Implement multi-layer pyramid approach to toponym extraction	✓
Week 10	Implement toponym rectification and amalgamation algorithms. Create ground truth labels for third map.	✓
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.	✓
Week 14	Prototype toponym-disagreement visualizer. Finalize Wiki and deliver presentation.	✓
