nicknames 0.1.1

Hand-curated dataset of English given names and nicknames

Nicknames

A hand-curated CSV file containing English given names (first name) and their associated nicknames or diminutive names.

There are Java, Perl, Python, and R parsers provided for convenience.

This is a relatively large list with roughly 1600 names. Any help from people to clean this list up and add to it is greatly appreciated.

This lookup file was initially created by mining this genealogy page. Because the lookup originates from a dataset used for genealogy purposes there are old names that aren't commonly used these days, but there are recent ones as well. Examples are "gregory", "greg", or "geoffrey", "geoff". There was also a significant effort to make it machine readable, i.e. separate it with commas, remove human conventions like "rickie(y)" would need to be made into two different names "rickie", and "ricky".

This project was created by Old Dominion University - Web Science and Digital Libraries Research Group. More information about the creation of this lookup can be found on this blog post about the creation of this library

Python API

The Python parser is available on PyPI from

pip install nicknames

and then you can do:

from nicknames import NickNamer

nn = NickNamer()

# Get the nicknames for a given name as a set of strings
nicks = nn.nicknames_of("Alexander")
assert isinstance(nicks, set)
assert "al" in nicks
assert "alex" in nicks

# Note that the relationship isn't symmetric: al is a nickname for alexander,
# but alexander is not a nickname for al.
assert "alexander" not in nn.nicknames_of("al")

# Capitalization is ignored and leading and trailing whitespace is ignored
assert nn.nicknames_of("alexander") == nn.nicknames_of(" ALEXANDER ")

# Queries that aren't found return an empty set
assert nn.nicknames_of("not a name") == set()

# The other useful thing is to go the other way, nickname to canonical:
# It acts very similarly to nicknames_of.
can = nn.canonicals_of("al")
assert isinstance(can, set)
assert "alexander" in can
assert "alex" in can

assert "al" not in nn.canonicals_of("alexander")

# You can combine these to see if two names are interchangeable:
union = nn.nicknames_of("al") | nn.canonicals_of("al")
are_interchangeable = "alexander" in union
