yasbd-lib vs PySBD: Two Approaches to Sentence Boundary Detection
Two Python libraries, PySBD and yasbd-lib, tackle sentence boundary detection with different architectures. PySBD uses a transformation pipeline that modifies text, while yasbd-lib treats text as immutable and uses pointer-based filtering. yasbd-lib supports 39 languages, 17 more than PySBD, and natively tracks character offsets.
