Korpusannotaatiota, or corpus annotation, is the process of adding linguistic information to a collection of texts, known as a corpus. This information can take many forms, such as part-of-speech tags, word sense disambiguation, named entity recognition, syntactic parsing, or semantic roles. The goal of annotation is to make the corpus more useful for linguistic research and the development of natural language processing (NLP) applications.

The annotation process typically involves human annotators who follow specific guidelines to label the text. For instance, in part-of-speech tagging, annotators assign grammatical categories like noun, verb, or adjective to each word. In named entity recognition, they identify and classify named entities such as persons, organizations, and locations. The quality of the annotation is crucial, and inter-annotator agreement, which measures the consistency between different annotators, is often used as a metric for reliability.

Annotated corpora serve as valuable resources for various tasks. Linguists can use them to study language patterns, test hypotheses, and gain insights into language variation and change. NLP researchers and developers employ annotated corpora to train and evaluate machine learning models for tasks like text classification, machine translation, and information extraction. The development of sophisticated annotation tools and platforms has facilitated the creation of larger and more complex annotated datasets, driving advancements in the field of computational linguistics.
