Experience
Information Extraction
Our team designed, implemented, and deployed to production an information extraction and post-processing solution to automate insurance claims processing.
我们的应用程序接收到一个图像, 通过OCR组件发送它, 根据保险公司的业务逻辑处理原始OCR输出, 并使用所有类似字段的价格预填充索赔表单, service item, provider, and more.
The team consisted of a machine learning engineer—for deployment and integration—and myself as a data scientist— performing BI research, problem scoping, 以及解决方案的设计和实现.
The solution achieved a 30% reduction in average handling time for human review of the claims.
