Annotated CRF annotations

Annotated CRF annotations


To quickly get the information you need about an article, book, or author, many people use a method such as annotation. It is a process that allows you to get a preliminary idea of unknown material.

What is it? 

Annotated CRF annotations process designed to summarize documents, books, or articles. In other words, this procedure is used to produce a summary of the content of a publication.


Text annotation consists of two parts: bibliographic description and text. This method is used to get information about the source but not to reveal the entire content of the article. Instead, annotations provide an objective, preliminary view of a previously unknown text. With their help, you can quickly find, systematize and remember the information you require in a short time.

Why is it important?

Recent advances in natural language processing have revealed a growing demand for textual data in insurance, health care, finance, and telecommunications. Because the target reader, in this case, a machine learning (ML) model, will evaluate the information presented and draw conclusions, annotations are needed.

Are abstracting and annotating the same thing?

An abstract is a written summary of a scientific publication on a given topic. In addition to the disclosure of the content, there is a personal assessment and the conclusions of the abstractor. In other words, such work makes the reader understand the essential aspects outlined in the article or book. Thereby relieving the need to study the primary source thoroughly.


This is why annotation and abstracting differ from each other. In the first case, an answer is given to what is written in the primary source. And in the second one, you can find out what is being said. So annotation is just answering questions about what is written and where. And abstracting lets, you know what the text contains.


What functions do abstracts perform?

They serve the following functions:


  • Searching. This kind of annotation is an information retrieval tool for specific data in a text.
  • Signaling. It acts as a kind of notification of the primary source. Looking at such an abstract, one can form the first impression of an article or book and decide whether to read it or not.

Requirements for annotations

To perform quality annotated CRF annotations, you must adhere to some requirements. For example, it is necessary to:


  • Consider the purpose, i.e., choose analytical or general, advisory or reference annotation type. This will determine the next point.
  • Decide on the length of the abstract. For example, a reference annotation is 500-800 characters. Other types of work can take from one to two pages of printed text.
  • Observe the chronological structure (all events in the abstract should have the same order as in the primary source).
  • Adhere to linguistic peculiarities.

To conclude


Annotating a text continues to be a desirable goal in most complex annotation projects. With the diversity of types and emerging new uses, text annotation provides models with the ability to read, comprehend, and respond to information in a human-like manner.
