Quica (Quick Inter Coder Agreement in Python) is a tool to run inter coder agreement pipelines in an easy and effective way. Multiple measures are run and results are collected in a single table than can be easily exported in Latex. quica supports binary or multiple coders.

If you already have a python dataframe you can run Quica with few liens of code! Let's assume you have two coders; we will create a pandas dataframe just to show how to use the library. As for now, we support only integer values and we still have not included weighting.
from quica.quica import Quica
import pandas as pd
coder_1 = [0, 1, 0, 1, 0, 1]
coder_3 = [0, 1, 0, 1, 0, 0]
dataframe = pd.DataFrame({"coder1" : coder_1,
"coder3" : coder_3})
quica = Quica(dataframe=dataframe)
print(quica.get_results())This is the expected output:
Out[1]:
score
names
krippendorff 0.685714
fleiss 0.666667
scotts 0.657143
raw 0.833333
mace 0.426531
cohen 0.666667It was pretty easy to get all the scores, right? What if we do not have a pandas dataframe? what if we want to directly get the latex table to put into the paper? worry not, my friend: it's easier done than said!

disagreeing_dataset = IRRDataset(disagreeing_coders)
quica = Quica(disagreeing_dataset)
print(quica.get_results())
print(quica.get_latex())you should get this in output, note that the latex table requires the booktabs package:
