Sentiment Analysis

The USCIS Service Center Operations Directorate (SCOPS) provides services for persons seeking immigration benefits while ensuring the integrity and security of our immigration system. As part of that mission, we issued a two-part survey asking users both quantitative and qualitative questions. USCIS performed a statistical analysis of the quantitative results and then used Natural Language Processing modeling software to assign "sentiments" to categories ranging from strongly positive to strongly negative. This model was eventually enhanced using a machine learning model to have better reusability and performance. This capability has been deployed to production for more than one year.
