    Entity Annotation

    Expertly and efficiently label named entities within text data to train NLP applications

What is
Entity Annotation?

Entity annotation is the process of labeling named entities (e.g. people, organizations, products) within a sections or pages of text. Named entity datasets train models to understand the structure and meaning behind a piece of text—a critical pre-processing step for many other natural language processing (NLP) tasks.

TaskUs has over a decade of experience helping the world’s leading companies develop named entity recognition (NER) systems. Our diverse, dynamic, and digital-savvy Teammates can handle entity annotation projects in 65+ languages to ensure that every entity in your text is identified and labeled to improve your model.
