Dataset Types

iMerit Dataset Types

iMerit handles image and video datasets for computer vision tasks like object detection, image segmentation, and image classification, essential for autonomous vehicles and facial recognition systems. They also manage text and document datasets, offering services such as NLP, sentiment analysis, and entity recognition. Additionally, iMerit works with audio datasets for speech recognition and transcription tasks.

Kili Technology Dataset Types

Kili Technology supports annotating various unstructured data formats, including images, videos, text documents, PDFs, satellite imagery, and conversational data. It provides dedicated interfaces for efficient labeling and supports LLM evaluation, supervised fine-tuning, and RLHF workflows. Data can be imported (CSV, JSON, image files) and exported (CSV, JSON, TensorFlow Record). Limitations include video annotation (bounding boxes only) and OCR integration.

Data Annotation Tools

iMerit Annotation Tools

For most annotations, iMerit experts use their proprietary tool, Ango Hub, for image, video, and text annotation. While they can work with clients' specific tools, they prefer using Ango Hub in all cases. Additionally, iMerit technology is available by subscription for individual annotation needs.

Kili Technology Annotation Tools

Kili Technology’s platform facilitates high-quality data labeling with AI-assisted automation, allowing adjustments to pre-labeled data. Users can employ their own custom models or utilize built-in AI models like ChatGPT and SAM for automatic pre-labeling, saving time on large datasets.

The platform supports various data types with tools for text, image, video, OCR, and geospatial annotation. However, some automated features are still developing, and complex tasks may require human annotators. Additionally, Kili's focus on its own tools might pose integration challenges with existing systems.

Kili’s data labeling platform
