Genni + Ethnea for the Author-ity 2009 dataset



Prepared by Vetle Torvik 2018-04-15

The dataset comes as a single tab-delimited ASCII encoded file, and should be about 717MB uncompressed.

• How was the dataset created?
First and last names of authors in the Author-ity 2009 dataset was processed through several tools to predict ethnicities and gender, including

Ethnea+Genni as described in:

First names, for some Author-ity records lacking them, were harvested from outside bibliographic databases.

&bull; What is the format of the dataset?
The dataset contains 9,300,182 rows and 10 columns
1. auid: unique ID for Authors in Author-ity 2009 (PMID_authorposition)
2. name: full name used as input to EthnicSeer)
3. EthnicSeer: predicted ethnicity; ARA, CHI, ENG, FRN, GER, IND, ITA, JAP, KOR, RUS, SPA, VIE, XXX
4. prop: decimal between 0 and 1 reflecting the confidence of the EthnicSeer prediction
5. lastname: used as input for Ethnea+Genni
6. firstname: used as input for Ethnea+Genni
7. Ethnea: predicted ethnicity; either one of 26 (AFRICAN, ARAB, BALTIC, CARIBBEAN, CHINESE, DUTCH, ENGLISH, FRENCH, GERMAN, GREEK, HISPANIC, HUNGARIAN, INDIAN, INDONESIAN, ISRAELI, ITALIAN, JAPANESE, KOREAN, MONGOLIAN, NORDIC, POLYNESIAN, ROMANIAN, SLAV, THAI, TURKISH, VIETNAMESE) or two ethnicities (e.g., SLAV-ENGLISH), or UNKNOWN (if no one or two dominant predictons), or TOOSHORT (if both first and last name are too short)
8. Genni: predicted gender; 'F', 'M', or '-'
9. SexMac: predicted gender based on third-party Python program (default settings except case_sensitive=False); female, mostly_female, andy, mostly_male, male)
10. SSNgender: predicted gender based on US SSN data; 'F', 'M', or '-'
