  2. Non-Ambiguous Placenames in GNS[Volz, et al, 2007]

  3. Non-Ambiguous Placenames in CHGIS Gazetteer

  4. Percentages of Non-Ambiguous Placenames - Comparison

  5. before dissolve instance 1: St. Petersburg (Russia) Begin=1703 End=1913 instance 2: Petrograd (Russia) Begin=1914 End=1923 instance 3: Leningrad (Russia) Begin=1924 End=1990 instance 4: St.Petersburg (Russia)Begin=1991 instance 5: St. Petersburg (Florida, USA) Begin=1892 after dissolve instance 1,4: St. Petersburg (Russia) instance 5: St. Petersburg (Florida, USA) Dissolving multiple historical instances of same spelling

  6. Non-Ambiguous Placenames - Dissolving Temporal Instances

  7. Comparison with Perseus Toponym Disambiguation

  8. Feature Type Thesauri

  9. No Standard Method Feature Type Crosswalks - Building a Concept Lattice

  10. Semantic Mapping Issues

  11. Semantic fragmentation = no feasible constraints on concepts Feature Type Crosswalk Based on Controlled Vocabulary

  12. Crosswalk of named periods and chronologies is needed
