Identity Criterion for Country type

Features for establishing identity relationships

  • name_match : There is a name_match if the names of the countries listed on both the sources match. Sometimes names may match approximately due to abbreviations or empirical names. For ex. USA vs United States of America or Holland vs Netherlands.

  • capital_name_match: There is a capital_name_match if the country capital listed in Freebase property /location/us_state/capital (Capital) matches with the capital on the other source.

  • date_founded_match: There is a date_founded_match, if the country founded date (year is enough) listed in Freebase property /location/dated_location/date_founded (Date founded) is same as the date on the other source.

  • date_dissolved_match: There is a date_dissolved_match if the country dissolved date (year is enough) listed in Freebase property /location/date_location/date_dissolved (Date dissolved) is same as the date on the other source.

  • calling_code_match: There is a calling_code_match if the country calling code listed in Freebase property /location/country/calling_code (Calling code) matches with the calling code on the other source.

  • ISO_short_name_match: There is an ISO_short_name_match, if the country ISO shortname listed in Freebase property /location/country/iso3166_1_shortname (ISO Short Name) matches with the ISO shortname on the other source.

  • FIPS_code_match: There is a FIPS_code_match, if the country FIPS code listed in Freebase property /location/country/fips10_4 (FIPS Code) is same as the FIPS code on the other source.

  • ISO_numeric_match: There is an ISO_numeric_match if the country ISO Numeric code listed in Freebase property /location/country/iso_numeric (ISO Numeric) matches with the ISO numeric code on the other source.

  • ISO_alpha2_match: There is an ISO_alpha2_match if the country ISO Alpha 2 code listed in Freebase property /location/country/iso3166_1_alpha2 (ISO Alpha 2) matches with the ISO alpha 2 code on the other source.

  • ISO_alpha3_match: There is an ISO_alpha3_match if the country ISO Alpha 3 code listed in Freebase property /location/country/iso_alpha_3 (ISO Alpha 3) matches with the ISO alpha 3 code on the other source.

General guidelines for establishing identity between two Countries

Here are some typical patterns for determining identity of two countries:

  1. name_match and capital_name_match. (Example 1)
  2. name_match and date_founded_match. (Example 2)
  3. name_match and date_dissolved_match. (Example 3)
  4. name_match and calling_code_match. (Example 4)
  5. name_match and FIPS_code_match. (Example 5)
  6. name_match and ISO_short_name_match. (Example 6)
  7. name_match and ISO_alpha3_match. (Example 7)
  8. name_match and ISO_alpha2_match. (Example 8)
  9. name_match and ISO_numeric_match. (Example 9)

Additional Patterns and Features

Identity features, patterns and examples for /location/location/ type are also applicable for establishing identity relationships in type /location/country.

Examples





Pattern 1 Example 1: Permalink Here the names of the countries and their capitals match on both the sources. Hence it is a match.





Pattern 2 Example 2: Permalink Here the names of the countries and their founded date match on both the sources. Hence the countries are identical.





Pattern 3 Example 3: Permalink Here the names of the countries and their dissolved dates match on both the sources. Hence the countries are identical.





Pattern 4 Example 4: Permalink Here the names of the countries and their calling codes match on both the sources. Hence it is a match.





Pattern 5 Example 5: Permalink Here the names of the countries and their FIPS code match on both the sources. Hence it is a match.





Pattern 6 Example 6: Permalink Here the names of the countries and their ISO Short Names match on both the sources. Hence the countries are identical.





Pattern 7 Example 7: Permalink Here the names of the countries and their ISO Alpha 3 codes match on both the sources. Hence the countries are identical.





Pattern 8 Example 8: Permalink Here the names of the countries and their ISO Alpha 2 codes match on both the sources. Hence the countries are identical.





Pattern 9 Example 9: Permalink Here the names of the countries and their ISO Numeric codes match on both the sources. Hence the countries are identical.
