Supplementary Material of "Improving Traceability Link Recovery Using Fine-grained Requirements-to-Code Relations"

This is the supplementary material of the paper "Improving Traceability Link Recovery Using Fine-grained Requirements-to-Code Relations". In this paper, we explore the performance of word embedding-based fine-grained requirements-to-code relations in automated traceability link recovery. The repository includes the code as well as the datasets used. To fully enable the potential of a word embedding based approach, we translated the identifier in two datasets (SMOS and eTour) to match the prevalent language. Attribution (of datasets used): The original SMOS and eAnci datasets can be attributed to Gethers et al., On integrating orthogonal information retrieval methods to improve traceability recovery.
