 ## Features
 
+* [OCR-D compliant](https://ocr-d.de/en/spec/ocrd_eval#character-error-rate-cer) normalized similarity for edit-distance based metrics based on characters, letters and words
+* choose from textual metrics based on characters or words plus common Information Retrieval
+* choose from different UTF-8 Python norms
 * match groundtruth (i.e. reference data) and candidates by filename start
 * use geometric information to evaluate only specific frame (i.e. specific column or region from large page) of
   candidates (requires ALTO or PAGE format)
 * aggregate evaluation outcomes on domain range (with multiple subdomains) according to folder layout
-* choose from textual metrics based on characters or words plus common Information Retrieval
-* choose from different UTF-8 Python norms
 * formats: ALTO, PAGE or plain text for both groundtruth and candidates
 * speedup with parallel execution
 * additional OCR util:
