An NLP and data-for-ai company

Projects include Text annotation services from users for eCommerce purposes, hate speech severity, and tagging relevant information on mobile phone companies.

What makes us different?

We are developers of Natural Language Solutions. We used to be a language services company. We found that marrying both skills, our Data Department could offer text data annotation services for our government-funded research projects and to help other organizations improve their AI and specific Machine Learning projects.

Pangeanic has added our expertise in human-in-the-loop (HITL) quality control. Our PECAT tool allows for human review of machine-generated annotations to ensure the highest quality.



“We understand each client is different, each project is different and many projects are very specific. Our customized solutions make all the difference: PECAT is so flexible that it can be tailored to meet your specific labeling needs and requirements.”

Why Choose Pangeanic’s Text Annotation Solutions?:

Data annotation is pivotal in refining Machine Learning (ML) models. Through meticulous labeling and feature identification within datasets, AI systems are empowered to discern patterns more effectively. This translates to:

  • Recognizing customer intent in messages.

  • Unveiling insights from user search behaviors.

  • Elevating your content strategy with keyword extraction.


In addition to these direct benefits, text data annotation can also help to improve the overall quality of information extraction systems. By providing models with high-quality training data, annotators can help them to learn to identify and extract information more accurately. This can lead to improved performance on a wide range of information extraction tasks. For example, text data annotation can be used to improve the accuracy of named entity recognition (NER), which is the task of identifying and classifying named entities in text. NER is a critical component of many information extraction systems, and improving its accuracy can lead to improved performance on tasks such as information retrieval, question answering, and machine translation.

Other example of how text data annotation can be used in information extraction:

  • Customer relationship management (CRM) systems: CRM systems use text data annotation to extract information from customer interactions, such as emails, phone calls, and social media posts. This information can then be used to create a more complete picture of each customer.

  • Fraud detection systems: Fraud detection systems use text data annotation to identify fraudulent transactions. For example, a fraud detection system might use text data annotation to identify transactions that are associated with known fraudulent email addresses or phone numbers.

  • Medical research: Medical researchers use text data annotation to extract information from medical records. For example, a medical researcher might use text data annotation to extract information about a patient's symptoms, diagnoses, and treatments.

Text data annotation is a valuable tool for improving the performance of information extraction systems. By providing models with high-quality training data, annotators can help them to learn to identify and extract information more accurately.
