Named Entity RecognitionAdmin Scope
Zia Named Entity Recognition is a part of Text Analytics that processes textual content to extract key words and group them into various categorizes. For example, it can determine a word in a text to be the name of an organization, the name of a person, or a date, and add it to the appropriate category accordingly. Refer here for a list of all categories recognized by NER.
You can pass a block of text as the input of up to 1500 characters in a single request. The text is passed to getNERPrediction().
The zia reference used in the code snippets below is the component instance created to perform these operations. The promise returned here is resolved to a JSON object.
const result = await zia.getNERPrediction([
