As a Research Associate and Subject Matter Expert at Samasource, I have been performing data validation, data cleaning, data categorization and quality audit during data trends analysis, consistency detection, report generation to improve data integrity and model performance. Also, I wrote and improved annotation policies, processed complicated or unclear cases of data, assessed AI-output on quality and bias, and gave domain-specific advice and assistance in mentorship of annotators. The datasets that the project dealt with were in the thousands to millions of data points as well as daily outputs of about 500-2,000 tasks based on complexity.
