functionwords 0.5

Extract curated Chinese and English function words from texts.

functionwords

The functionwords package aims at providing curated Chinese and English function words.

For now, it supports four function word lists: modern Chinese ([chinese_simplified_modern][1]), classical Chinese ([chinese_classical_naive][2] and [chinese_classical_comprehensive][3]), and modern English (english). Chinese function words are only available in simplified form.

The FunctionWords class does the heavy lifting. Initiate it with the desired function word list name. The instance has two methods transform() and get_feature_names()) and three attributes (name, function_words, and description).

Name	# of function words	Description
chinese_simplified_modern	819	compiled from the [dictionary][1]
chinese_classical_naive	32	harvested from the [platforms][2]
chinese_classical_comprehensive	466	compiled from the [dictionary][3]
english	512	found in software

For more details, see FunctionWords instance's attribute description.

Installation
