Core

Input/Output

Reading, writing, creating, and merging LIWC dictionaries. Each reader and writer commits to one file format and one value-type; the caller picks the function whose name matches the data. Two schemas validate each shape: dx_schema for binary dictionaries and dx_weighted_schema for weighted dictionaries (signed values allowed, e.g. for sentiment lexicons like VADER).

create_dx	Create a binary dictionary DataFrame from a category-to-terms mapping.
read_dic	Read a binary LIWC dictionary from a .dic file.
read_dicx	Read a binary .dicx file.
read_dicx_weighted	Read a weighted .dicx file.
write_dic	Write a binary dictionary to a .dic file.
write_dicx	Write a binary dictionary to a .dicx file.
write_dicx_weighted	Write a weighted dictionary to a .dicx file.
merge_dx	Merge multiple dictionaries into a single dictionary.
drop_category	Remove one or more categories from a dictionary.
dx_schema	A lightweight pandas DataFrame validator.
dx_weighted_schema	A lightweight pandas DataFrame validator.
