A sociolinguistics package for NLP research.

Project description

pySCIL

New deployment of the SCIL toolset using NLP tools from Python

The Socio-cultural Content in Language (SCIL) toolset intents to explore and develop novel designs, algorithms, methods, techniques and technologies to extend the discovery of the social goals of members of a group by correlating these goals with the language they use. (description via IARPA)

Installation

The following are instructions on how to install pySCIL from PyPI.

Type the following in your terminal. Make sure you are using Python 3.6+

pip install pySCIL

Usage

Include the above imports at the top of your program file

import json
from scil import scil

To begin analyzing a dialogue type the following code

with open("pathtojson.json") as f:
  obj = scil.SCIL(f)
obj.preprocessStanford()

Make sure that your json file is formatted properly. An example can be seen in the jsontemplate.json file

You can also use the NLTK Part of Speech tagger. It has noticeably less accuracy but is also a lot faster. To use it you can use obj.preprocessNLTK()

From here, you can now start to call functions to do analysis on the data. See below functions section for more details. As an example.

print(obj.TopicControlFunctions([1,0.5,0.5,0.5]))

Functions

Each service has a main function that gathers data from all sub-functions and creates a combined metric. These sub-functions can also be called individually. Below are all the callable functions outlined along with what sort of data they require to be present in the provided json file.
