What Is PDF Tagging

PDF tagging is the process of creating a structured and accessible PDF file. In this case, text tagging means creating an underlying layer to the document similar to the HTML structure. It is necessary to identify such parts of the file as headings, lists, links, columns, chapters, sections, tables, images, etc. Tagging PDF documents allow adding an alternative description to pictures and images as well.

Although some programs export files in the already tagged format (MS Word and PowerPoint), the majority of applications do not do that (Google Docs for instance). But even if automatic text annotation is available, it is usually far from perfect. It still needs to be reviewed manually.

Why is tagging text important? It creates a document that a program can read (AT apps or text-to-voice readers). It also ensures that the document performs seamlessly on various screens and devices and by people with any physical or developmental impairments. And it ensures a structured and organized approach to documents.

Characteristics of a Full Accessible PDF

Professional text labeling ensures that a PDF is fully accessible. It is commonly used for Natural Language Processing (NLP annotation services) to train algorithms. Such documents have the following characteristics:

Proper reading structure and order for every page of the document. So whether it is accessed by a text tagging machine learning tool or a person using an assistive device, it is organized in a logical order;

tech icon

Tags and text data annotation for all logical elements. Those can be chapters, sections, lists, tables, hyperlinks, images, graphs, etc. All of them need to be manually tagged for a fully accessible PDF;

mobile icon

A clear and correct description of images. Automatic tagging is not very useful in this regard. A correct description of any image is best done by professionals as they know what elements are important for the reader’s perception;

scheme icon

Properly structured tables. Tables are complex elements, which require professional text annotation services to be done accurately. Otherwise, the table content might become incomprehensible for readers or text mining semantic analysis tools. It is also essential for web accessibility of the content;

Language confirmation with proper labels for easy translation, comprehension, and tone analysis.
