Intent Labeling & Entity Extraction.

A leading organization required high-quality, expertly-annotated data to train its Natural Language Understanding (NLU) model. CapeStart provided three levels of data labeling that covered text classification, identifying intent, and extracting key entities, to help train the NLU model. This allowed the client to automate, and ultimately improve, its service.

Text Classification.

CapeStart provides ongoing data labeling and text classification to train different NLP models for a global research and advisory firm that works within several industries.

Point cloud - Object Detection and 3D Bounding Box.

CapeStart performed object detection and 3D bounding box annotation with object attributes for a leading LiDAR solutions company to train their autonomous driving model. The project involved annotation of point cloud imaging of highway traffic scenes including vehicles, traffic signals, billboards, and pedestrians.

Image - Bounding box.

CapeStart worked with a leading IT consulting company to provide pixel sharp bounding box and polygon annotations. This training data was used for facial recognition and image/logo identification.
