Labeling textual datasets for sentiment analysis, entity linking, translation pairs, content classification, and training large language models (LLMs).
• Experienced linguists managing grammar, dialects, slang, and technical context tagging.• Inter-annotator agreement pipelines (Cohen's Kappa metrics) guarantee high quality.• Strict data security sandboxes conform to standard corporate protection frameworks.
Schema Definition: Aligning annotation guidelines, target tags, and project metrics.Pilot Phase: Labeling a tiny test dataset to verify annotator alignment.Annotation Run: Executing text tagging inside secure label interfaces.Quality Check: Reviewing data samples and applying consensus metrics to filter errors.
02
Image & Video Annotation
Drawing bounding boxes, semantic segmentation, polygon outlines, and tracking keypoints on images or video frames for computer vision models.
• High precision bounding box alignments down to the single pixel level.• Video tracking experts optimizing object linkages across consecutive video frames.• Experienced handling specialized scientific, medical (DICOM), and industrial image datasets.
Target Definition: Setting criteria for label thresholds, margins, and naming rules.Labeling Pass: Drawing polygons, labels, boxes, or landmark keypoints.Temporal Alignment: Tracking linked objects across frame steps for video files.Consensus Check: Comparing multiple annotator outputs to guarantee maximum dataset precision.
03
