It enables businesses to train custom named entity recognition (NER) models to identify specific entities relevant to their operations, such as location, names, and dates. **Value Proposition** Leveraging Amazon Comprehend allows companies to streamline the training of accurate custom entity recognition models, reducing manual effort and enhancing data insights. **Practical Solutions** A pre-labeling tool has been developed using AWS Step Functions to simplify the preparation of training data. This tool automates the pre-annotation of documents using existing tabular entity data, significantly reducing manual work required for training custom entity recognition models in Amazon Comprehend. **Architecture** The pre-labeling tool comprises multiple AWS Lambda functions orchestrated by a Step Functions state machine. It utilizes fuzzy matching and a pre-trained Amazon Comprehend entity recognizer model to generate pre-annotations. **Deployment** Managers can easily deploy the pre-labeling tool by cloning the repository to their local machine and leveraging the AWS Serverless Application Model (AWS SAM) for infrastructure setup. **Practical Implementation** Before using the pre-labeling tool, managers can prepare their data by creating a pre-manifest file that maps PDF documents with the entities to be extracted. This file contains the expected text to extract and the corresponding entity type. **Running the Tool** Once the pre-manifest file is prepared, managers can execute the pre-labeling tool, providing necessary inputs such as the pre-manifest, prefix, entity types, and other optional parameters. The tool automates the annotation process and generates outputs for further use. **Conclusion** The pre-labeling tool offers a powerful way for companies to leverage existing tabular data, accelerating the process of training custom entity recognition models in Amazon Comprehend. It enables quick unlocking of the value of historical entity data, making custom entity recognition with Amazon Comprehend more accessible than ever. **About the Authors** Oskar Schnaack and Romain Besombes are experts in the field of AI and machine learning, passionate about making these technologies accessible and impactful for customers. **AI Solutions for Middle Managers** Discover how AI can redefine your way of work, identify automation opportunities, define KPIs, select AI solutions, and implement gradually to drive business impact. **Connect with us** For AI KPI management advice and continuous insights into leveraging AI, reach out at hello@itinai.com or stay tuned on our Telegram or Twitter. **Spotlight on a Practical AI Solution** Consider the AI Sales Bot designed to automate customer engagement 24/7 and manage interactions across all customer journey stages.
