3. OCR Annotation for Document Layout Preservation and Object Detection
One of the standout features of UBIAI is its Optical Character Recognition (OCR) annotation capability. This feature allows users to annotate native PDF documents, scanned images, pictures, invoices, or contracts while preserving the layout of the documents. This is particularly useful for industries where PDFs are extensively used, such as finance, legal, and healthcare, as it eliminates the need for tedious manual editing and ensures accurate annotations,also with the object detection feature it allows you to create bounding boxes around elements in an image and label them. This is particularly beneficial for enhancing your OCR annotations by identifying non-textual entities like signatures, figures, and images.
4. Auto labeling
Using UBIAI’s auto-labeling feature can be helpful in the following ways:
UBIAI enables the automatic labeling and annotation of words by linking one or more dictionaries to the system. The tool is designed to automatically apply annotations to the text found in both the dictionary and the corpus document, streamlining the annotation process.
UBIAI allows auto-labeling of the uploaded document(s) using a fine-tuned ML model on your annotation. For each entity, the F score, precision, and recall score will be displayed.After model training, you have the option to export the ready-to-use model for your application.
Rule-based matching allows auto-labeling of documents by combining multiple rules,It will enable instant auto-labeling of documents by using multiple pre-defined rules such as regular expressions, Part of Speech (POS), and patterns (email, number, phone number, etc….).

5. Advanced Annotation Export and Integration
UBIAI provides users with the flexibility to export annotations in multiple formats, including spacy, IOB, Amazon Comprehend, and more. This compatibility allows seamless integration with popular NLP frameworks and models. Additionally, UBIAI supports different data formats, enabling easy data exchange and integration with other tools or platforms.
6. Zero-shot and Few-shot Labeling
You now have the ability to supply a minimal number of labeled examples, or even none at all, and allow GPT to instantaneously auto-label your data, accommodating various formats including PDFs. This innovative feature facilitates a more efficient and streamlined data annotation process, empowering your team to achieve its maximum potential.
7. Team Management and Performance Tracking
To enhance collaboration and ensure consistency in annotation projects, UBIAI offers robust team management features.
