Labeling Experience

UI Element Labeling Practice

OtherImageBounding Box
I labeled user interface (UI) components and screen elements within structure-based image datasets. The process included annotating interface elements and developing repeatable labeling systems for consistency. My efforts focused on maintaining accuracy and clarity across multiple UI screens. • Labeled UI elements such as buttons and forms • Developed structured labeling systems for UI • Ensured consistent annotation across screens • Flagged ambiguous or inconsistent UI elements

OtherTextClassification
I annotated and reviewed AI training datasets, labeling text by intent, sentiment, and user context. My work involved applying strict guidelines, identifying edge cases, and maintaining consistency across batches. I flagged unclear data and ensured dataset integrity through careful review. • Classified text samples for intent and tone • Reviewed and corrected annotation outputs • Applied guidelines for uniform labeling • Maintained dataset cleanliness and structure

Content Structuring & Data Cleanup

OtherTextClassification
I organized unstructured content into clean, analyzable datasets by tagging and grouping based on meaning and usage. My process included data cleanup, removing inconsistencies, and structuring spreadsheets for future analysis. This ensured high-quality, labeled data for downstream use. • Tagged and grouped heterogeneous content • Cleaned duplicate or inconsistent entries • Created structured spreadsheets for analysis • Maintained data integrity for reuse
