Labeling Experience

Linguistic Annotator

TextRLHF

Managed a high-volume Technical-Linguistic Hybrid project for the Ghana Engineering Council, auditing over 1000+ datasets composed of both complex engineering terminology and extensive natural language content. The primary scope involved performing semantic disambiguation and linguistic validation to ensure that natural language explanations remained technically accurate while maintaining professional fluency. By adhering to strict Ground Truth verification against national engineering codes, I achieved a 94%+ accuracy rate in detecting "semantic shifts" and technical hallucinations within outsourced data. This role required balancing high-level subject matter expertise with nuanced linguistic auditing, ensuring that the final documentation was both scientifically sound and accessible to human stakeholders.
