Requirements

• Python 2.7
• Tensorflow 1.1.0

Instructions to run:

Preprocessing:

• Change working directory to code/main/
• Create a new directory named 'tmp'
• Run: python mt_main.py preprocessing

Pointer model:

• First run pre-processing
• Change working directory to code/main/
• python mt_main.py train 10 pointer_model For inference:
• Change working directory to code/main/
• python mt_main.py inference tmp/pointer_model7.ckpt greedy

Normal seq2seq model:

• Look at seq2seq branch of the repo

Post-Processing:

There are two post-processing actions which one may be interested in performing:

1. Visualizing attention matrices
2. Replacing UNKS in hypothesis with their highest-aligned (attention) input tokens. For both of these actions, refer to the running instructions in code/main/post_process.py (comments commencing the file). The file can be run in two modes, to perform 1 (write) and 2 (postProcess) respectively*. *Not elaborated on here to preserve conciseness and clarity. Note that the path to test file is hard-coded in the post_process.py file, so to try with a new file,one will have to make corresponding changes.

Baseline (Dictionary):

• Change working directory to code/baselines/
• Run: python dictionary_baseline.py ../../data/shakespeare.dict ../../data/test.modern.nltktok ../../data/test.dictBaseline
• The test.dictBaseline file contains the output (Shakespearean) of the dictionary baseline.
• To evaluate BLEU:
  • Change working directory to code/main/
  • Run: perl multi-bleu.perl -lc ../../data/test.original.nltktok < ../../data/test.dictBaseline

Baseline (statistical MT)

• Please follow instructions in "Wei Xu, Alan Ritter, William B Dolan, Ralph Grish- man, and Colin Cherry. 2012. Paraphrasing for style. In 24th International Conference on Computational Linguistics, COLING 2012."
