k-text-analyzer
v0.2.1
Published
A simple library that parses a blob of text and compares it to a configuration file for level of risk. uses would include looking for threats or suicidal ideations. This is not fool-proof and is a work in progress.

Text Risk Analysis
This module will aid in determining the risk of a post based upon a supplied configuration. Configurations can be customized depending on context. For example, one configuraiton could be used to analyze a risk level for self harm while another configuration could be created to measure if there is a threat to another person.
The text will be passed in and phrases and words will be analyzed to determine a score. The score is not to be compared with other configurations, as the score exists simply to compare to a baseline of 0. In some configurations, a score of 100 would be a definitive warning while in others it would be just a caution. How each application handles the score will depend on the application.
Goal
This module was created for use in a few applications created by KVSS Technologies. After being used in production, the logic was separated and open sourced. It is hoped that the community will improve the algorithms and generate improved configurations to be used.
Installation
The library is written in TypeScript and is distributed in ES5. In a NodeJS project, usage should be as simple as
var analyzer = require("k-text-analyzer");
var a = new analyzer.Analyzer();
var score = a.analyze("YOUR TEXT");
Building
We have attempted to make building and testing be as self-contained as possible. Therefore, the node_modules directory will be heavy as we will make local copies of TypeScript and Mocha available and referenced.
To build, you should clone the repository and then run
npm install
npm run build
This will create a ./build
directory with the generated JS files from the ./src
directory.
Testing
To test the code, run
npm run test
This will build the project and then use Mocha to test the generated Javascript. The tests can be found in ./src/tests
or ./build/tests
Documentation
The code has attempted to be as clear as possible while also having clear comments. We use TypeDoc to generate HTML documentation. At build time, we generate the documentation for you, but you may also generate the documentation by running
npm run doc
This will create a ./documentation
directory you may browse with your favorite browser.
