Robyn Speer b22a4b0f02 Strip apostrophes from edges of tokens The issue here is that if you had French text with an apostrophe, such as "d'un", it would split it into "d'" and "un", but if "d'" were re-tokenized it would come out as "d". Stripping apostrophes makes the process more idempotent. Former-commit-id: `5a1fc00aaa`		2015-08-25 12:41:48 -04:00

Tools for working with word frequencies from various corpora.

Author: Robyn Speer

Installation

wordfreq requires Python 3 and depends on a few other Python modules (msgpack-python, langcodes, and ftfy). You can install it and its dependencies in the usual way, either by getting it from pip:

pip3 install wordfreq

or by getting the repository and running its setup.py:

python3 setup.py install

To handle word frequency lookups in Japanese, you need to additionally install mecab-python3, which itself depends on libmecab-dev. These commands will install them on Ubuntu:

sudo apt-get install mecab-ipadic-utf8 libmecab-dev
pip3 install mecab-python3

Unicode data

The tokenizers that split non-Japanese phrases utilize regexes built using the unicodedata module from Python 3.4, which supports Unicode version 6.3.0. To update these regexes, run scripts/gen_regex.py.
