cd paragraph

th preprocess.lua -config config-preprocess

First replace <path to embedding txt file> in preprocess_embedding.sh with real path, then run:

./preprocess_embedding.sh

mkdir data/embs

cd data 

th convert.lua

    cd ..

th train.lua -config config-train

You can adjust the rnn size for paragraph encoder and sentence encoder by changing para_rnn_size and sent_rnn_size respectively.

th translate.lua -model model/<model file name> -config config-trans

cd sentence

th preprocess.lua -config config-preprocess

python preprocess_embedding.py 
--embedding  <path to embedding txt file>
--dict ./data/qg.{src,tgt}.dict 
--output ./data/qg.{src,tgt}.840B.300d.npy

th ./data/convert.lua

th train.lua -config config-train

th translate.lua -model model/<model file name> -config config-trans

cd qgevalcap
./eval.py --out_file <path to output file>

Sentence: however , the rainforest still managed to thrive during these glacial periods , allowing for the survival and evolution of a broad diversity of species .

Human: did the rainforest managed to thrive during the glacial periods ?

H&S system: what allowed for the survival and evolution of a broad diversity of species?

Ours (sentence): why do the birds still grow during glacial periods ?

Ours (paragraph): why did the indigenous specis begin to grow during the glacial period ?

Sentence: as an example , income inequality did fall in the united states during its high school movement from 1910 to 1940 and thereafter .

Human: during what time period did income inequality decrease in the united states ?

H&S system: where did income inequality do fall during its high school movement from 1910 to 1940 and thereafter as an example ?

Ours (sentence): when did income inequality fall in the us ?

Ours (paragraph): when did high school movement begin ?

Sentence: about 61.1 % of victorians describe themselves as christian .

Human: what percentage of victorians are christian ?

H&S system: who do about 61. 1 % of victorians describe themselves as?

Ours (sentence): what percent of victorians describe themselves as christian ?

Ours (paragraph): what percent of victorians identify themselves as christian ?
