Get Started

What is Invoice Data Annotation Process

Data annotation is the process of labeling and tagging data with relevant information to create a labeled dataset for training machine learning models. It involves annotating data points with specific labels, such as identifying objects in images or categorizing text, to provide supervised learning signals for AI algorithms.

Invoices can be complex and diverse, containing a wide range of data such as vendor details, invoice numbers, dates, line items, and more. Our team of highly skilled data annotators is well-versed in the intricacies of invoice data, meticulously labeling and annotating each element to create reliable training datasets.

Our dedicated team of expert annotators is equipped with the knowledge and expertise to meticulously label and annotate invoice data. We understand the nuances and complexities of invoice structures, ensuring that each element is accurately identified and labeled, no matter how intricate the layout.

Pixl Text Annotation Services

We employ a comprehensive and meticulous text annotation process to ensure the highest quality labeled datasets. Our skilled annotators meticulously analyze and label text data, enabling machine learning models to understand and interpret textual information accurately. We follow industry-standard guidelines and leverage our deep domain expertise to annotate various text elements, such as named entities, sentiment analysis, parts of speech, and more. By combining human intelligence with advanced annotation tools, we guarantee precise and consistent annotations, empowering your AI models to extract valuable insights and make informed decisions.

Our Text Annotation Techniques:


Named Entity Recognition (NER)

We utilize NER to identify and classify named entities within the text, such as names of people, organizations, locations, dates, and more. This technique enables AI models to extract and understand specific entities in unstructured text data.


Text Categorization

Our text categorization technique involves annotating text documents with predefined categories or classes. This enables AI models to classify and organize text data based on specific topics or themes, facilitating efficient information retrieval and analysis.


Entity Linking

Entity linking is used to connect named entities in text to their corresponding entities in a knowledge base or database. By linking entities to relevant resources, AI models can access additional information and enhance their understanding of the text.


Coreference Resolution

We employ coreference resolution to identify and resolve pronouns or noun phrases that refer to the same entity in a text. This technique improves the coherence and clarity of annotated data, aiding AI models in accurate comprehension and interpretation.


One-Stop solution for All your Document Annotation Needs

Streamline your workflow with Pixl and enjoy efficient, error-free invoice text annotation


Table-Based Annotation Process

The invoice table includes line-item descriptions, quantities, and amounts on each line. By default, Pixl will aim to extract all the lines from the invoice. If you don’t need all the lines, you can train it to extract only one line from a specific invoice layout.

Key Value-Based Annotation Process

In the realm of data annotation, the technique of value-based annotation serves as a powerful tool to precisely capture crucial elements like invoice numbers, dates, subtotals, taxes, and total amounts.
