New semCER metric improves OCR and VLM evaluation by weighting error severity

Researchers have developed a new metric called semCER to evaluate optical character recognition (OCR) and vision-language models (VLMs). Unlike the standard Character Error Rate (CER), semCER assigns varying penalties to different types of errors based on their severity, as judged by an LLM. This approach aims to better reflect how human readers perceive the damage caused by transcription errors across various languages, including English, Vietnamese, Standard Chinese, and Telugu. AI

IMPACT Introduces a more nuanced evaluation metric for OCR and vision-language models, potentially leading to better model development.
