A spelling similarity measure for cognate identification.
spsim is a Python 3 module that implements a spelling similarity measure for identifying cognates across languages, taking into account spelling differences that are characteristic of each language pair, as described in [Gomes2011].
Note: in the examples below,
$ denotes the Bash prompt and a Linux, MacOs or similar *nix environment is assumed.
Install as usual:
$ pip3 install spsim
Example command line usage:
$ # first let's get some pairs of words that may be cognates: $ wget http://research.variancia.com/spsim/maybe_enpt.txt $ cat maybe_enpt.txt pharmacy farmácia arithmetic aritmética $ # If we don't give any example cognates, SpSim will be equivalent to $ # 1 - edit_distance / max_len_of_strings $ # Note that by default spsim matches accentuated characters, i.e. a == á $ echo "" > empty.txt $ spsim empty.txt maybe_enpt.txt pharmacy farmácia 0.5 arithmetic aritmética 0.8 $ now let's get some example cognates: $ wget http://research.variancia.com/spsim/examples_enpt.txt $ cat examples_enpt.txt alcohol álcool alpha alfa anomaly anomalia mathematics matemática methodology metodologia metric métrica morphine morfina photos fotos $ # by giving these examples to spsim, it will learn to ignore certain differences: $ spsim examples_enpt.txt maybe_enpt.txt pharmacy farmácia 1.0 arithmetic aritmética 1.0
