This is the rewriter model described in ParaBank (Hu et al. 2019).

Required packages are listed in requirement.txt. Please download params.best from the project website and place it under this directory.

Usage: echo -e "This is a test.\tis|test\twas|exam" | ./paraphrase.sh, where "is" and "test" are negative constraints, and "was" and "exam" are positive constraints.
