Best Data Labeling Software

    Data labeling software—also known as training data, data annotation, data tagging, or data classification software—provides a tool set for businesses to turn unlabeled data into labeled data and build corresponding artificial intelligence algorithms. Within these tools, the user inputs a given dataset and the software provides a label through machine learning-assisted labeling, a human taskforce, or the user themselves. Some platforms allow for the combination of the three, giving the user (or the system itself) the ability to choose who or what is doing the labeling, based on factors such as price, quality, and speed.

    Data labeling tools differ as it relates to the types of data (e.g., image, video, audio, and text), as well as the subsets of those types (e.g., satellite imagery, LIDAR, etc.), they support. The types of annotation also vary and include image segmentation and object detection for image data; named entity recognition (NER) and sentiment detection for text data; and transcription and emotion recognition for speech annotation. To assess the quality of the labels, most tools use metrics like consensus, ground truth, and more.

    For supervised learning, a type of machine learning, to get off the ground and make accurate predictions based on inputted data, there must be labeled data in place. Therefore, data labeling software is a crucial component in many artificial intelligence projects. This software can often integrate with data science and machine learning platforms, whereby the labeled data from the data labeling software helps to train an algorithm.

    To qualify for inclusion in the Data Labeling category, a product must:

    Integrate a managed workforce and/or data labeling service
    Ensure labels are accurate and consistent
    Give the user the ability to view analytics that monitor the accuracy and/or speed of labeling
    Allow the annotated data to be integrated into data science and machine learning platforms to build machine learning models
