IRS Non Profit Financial Data and Political Partisanship

We classified the political ideology of all non-profits in the public IRS 990 Form dataset by using a Bayesian classification of their self-reported mission statements, using a classifier trained on the political speeches of members of Congress.

本研究采用贝叶斯分类方法，对公共美国国内收入署（IRS）990表格数据集中所有非营利组织的政治理念进行了分类，该分类方法基于对国会成员政治演说的分类器进行训练，以分析其自报的使命声明。
