📄 Papers

The most cited first (OpenAlex and our library).

1. Morfessor 2.0: Toolkit for statistical morphological segmentation (2014 · 168 citations)
   Morfessor 2.0 is a re-implementation of the Morfessor Baseline algorithm, a probabilistic method for unsupervised morphological segmentation.
2. Uncertainty-Aware Natural Language Inference with Stochastic Weight Averaging (2023 · 6 citations)
   Human readers often disagree on whether one sentence follows from another, yet NLI benchmarks usually reduce each example to a single majority label.
