What is Linguistic Annotation?

Linguistic annotation, also known as corpus annotation, is the tagging of language data in text or spoken form. Linguistic annotation seeks to identify and flag grammatical, phonetic, and semantic linguistic elements within a body of text or audio recording. Utilizing our curated staff fluent in over 300 languages and dialects, Lionbridge can handle projects focusing on both major and niche languages at scale. We leverage our large crowd to find qualified annotators native in the language of your corpus or the target language of your NLP model.

Let Lionbridge annotate your data and provide your machine learning models with a solid ground truth.
