What is Text Annotation?

Text annotation is the process of labeling and tagging textual content with metadata to teach machine learning models how to interpret language in context. This includes identifying and tagging:

● Entities (names, locations, dates)
● Parts of speech
● Sentiments and emotions
● Intent and topic classification
● Relationships between terms
● Syntax and grammatical structure
● Custom taxonomies based on your use case

These annotations are critical for NLP systems like chatbots, voice assistants, recommendation engines, document summarizers, and intelligent search engines to function accurately.
