A library of three functions. ipa2asjp
takes an IPA-encoded sequence and converts it into an ASJP-encoded sequence. asjp2ipa
tries to do the opposite. tokenise
takes an ASJP-encoded string and returns a list of tokens.
>>> from asjp import ipa2asjp, asjp2ipa, tokenise >>> ipa2asjp('zɛmʲa') 'zEmy~a' >>> ipa2asjp(['z', 'ɛ', 'mʲ', 'a']) ['z', 'E', 'my~', 'a'] >>> asjp2ipa('zEmy~a') 'zɛmʲa' >>> tokenise('zEmy~a') ['z', 'E', 'my~', 'a'] >>> ipa2asjp(asjp2ipa(tokenise('zEmy~a'))) == tokenise('zEmy~a') True >>> ipa2asjp(['z', 'ɛ', 'mʲ', 'a']) == tokenise(ipa2asjp('zɛmʲa')) True
ASJPcode, more commonly referred to as the ASJP alphabet or simply as ASJP, is a simplified transcription alphabet introduced in Brown et al. (2008) and then slightly modified in Brown et al. (2013); the latter is considered the alphabet's spec for the purposes of this package.
The ASJP alphabet is used for transcribing the ASJP Database, an actively developed database aiming to provide the translations of a set of 40 basic concepts into all the world's languages. Both alphabet and database are employed in the field of computational historical linguistics, e.g. in Jäger (2013) or Wichmann et al. (2011).
ipa2asjp(ipa_seq)
takes an IPA string or sequence of string tokens and converts it into an ASJP string or sequence of string tokens. Raises a ValueError
if the input does not constitute a valid IPA sequence.
asjp2ipa(asjp_seq)
takes an ASJP string or sequence of string tokens and converts it into an IPA string or sequence of string tokens. As ASJP encodes much less information than IPA, something like asjp2ipa(ipa2asjp(ipa_seq)) == ipa_seq
would rarely hold true. Raises a ValueError
if the input does not constitute a valid ASJP sequence.
tokenise(asjp_string)
takes an ASJP string and converts it into a list of ASJP tokens. Raises a ValueError
if the input cannot be unambiguously tokenised.
tokenize(asjp_string)
is an alias for tokenise(asjp_string)
.
This is a standard Python 3 package with a single dependency, ipatok. It is offered at the Cheese Shop, so you can install it with pip:
pip install asjp
or, alternatively, you can clone this repo (safe to delete afterwards) and do:
python setup.py test
python setup.py install
Of course, all of this could, and probably should, be happening within a virtual environment.
- lingpy is an extensive library for computational historical linguistics that includes functions for converting IPA to ASJP.
- ipatok is a library for tokenising IPA strings used by the
ipa2asjp
function for handling string input.
