PDF Studio

Overview

The PDF Annotation Studio allows annotators to interact with PDF documents and perform text classification or labeling by highlighting specific text segments and associating them with predefined labels.

Key Features

• Annotators can highlight specific portions of text directly within the PDF interface.
• Once highlighted, these text segments can be assigned labels from a predefined set, such as "Name," "Date," "Location," or any custom label relevant to the project.
• Intuitive text selection tools make it easy to highlight text, whether it's a single word, a phrase, or an entire paragraph.
• Additional tools for undo/redo, zoom, and navigation ensure a smooth annotation experience, even with large documents.

Main Sections of the PDF Studio:

• Section 1: Label Picker and Annotation Tools
• Section 2: PDF Studio Canvas (Center part)
• Section 3: Annotation Lists, Attributes, and Item Details (right-side panel)
• Section 4: Item Info & Controls (top-side panel)

Section 1: Label Picker and Annotation Tools

This section allows you to use labels and annotation tools to perform the annotation process. The available labels and tools are determined in the Recipe.

Label Picker

A Label Picker is a feature within the PDF annotation studio that allows you to select labels to highlight texts in the PDF.

You can perform the following activities on the Label Picker section:

• Scroll and click a label to activate it.
• Use the search bar to easily find labels.
• Resize the label list to better fit your number of labels by clicking and dragging the separator line at the bottom.

Annotation Tools

Below the Label Picker on the left-side panel, the Annotation Tools section provides various tools for creating and editing annotations. These tools include:

Text Tool

The Text Highlighting Tool in the Dataloop platform is a core feature designed to enable annotators to interact directly with text-based content, such as documents, PDFs, or other textual datasets.

It facilitates the extraction, classification, and organization of textual information by allowing users to highlight and label specific text segments.

Section 2: PDF Studio Canvas

The PDF Studio Canvas allows you to label the texts or sentences by using the text tool.
