Utilizing Lexical Similarity between Related, Low-resource Languages for Pivot-based SMT
Table 2: Comparison of pipelining (pip) and triangulation (tri) approaches for OS and BPE (BLEU). † means difference between pip and tri is statistically significant (p<0.05)

Subword-level models outperform other units for the pipelining approach to pivoting too. Triangulation and pipelining approaches are comparable for BPE and OS models Hence, we report results for only the triangulation approach in subsequent experiments.
