# mrtydi-v1.1-arabic (trained on MS MARCO)
Faiss flat index for Mr.TyDi v1.1 (Arabic), using mDPR fine-tuned on MS MARCO.
This index was generated on 2022/03/27 at commit [aa1c0e9](https://github.com/castorini/pyserini/commit/aa1c0e9a5bbfab406f8c73d23c91a009307096c6) on `cedar` with the following command:
```bash
lang=arabic
tarfn=mrtydi-v1.1-$lang.tar.gz
corpus=mrtydi-v1.1-$lang/collection/docs.jsonl
index_dir=mrtydi-mdpr-dindex-msmarco/$lang
wget https://git.uwaterloo.ca/jimmylin/mr.tydi/-/raw/master/data/$tarfn
tar –xvf $tarfn
gzip -cvf $corpus.gz > $corpus
shard_num=1
encoder=mdpr-mrtydi-0shot-msmarco-tied-encoder-converted
for shard_id in $(seq 0 `$shard_num - 1`) ; do
index_dir=mdpr-dindex/$lang-$shard_id
mkdir -p $index_dir
python -m pyserini.encode input --corpus $corpus \
--fields title text \
--delimiter "\n\n" \
--shard-id $shard_id \
--shard-num $shard_num \
output --embeddings $index_dir \
--to-faiss \
encoder --encoder $encoder \
--fields title text \
--batch 128 \
--fp16
done
```
Note that the delimiter are only supported after [Pyserini #1000](https://github.com/castorini/pyserini/pull/1000/commits/5021e12d1d2e1bc3d4015955bcf77076c5798ce6#diff-45356c3f5e9cd223bb23d7efea3f7ed834abbcd32f604eb7fdd138e364273241L104).
The index can be later reproduced on commit [7b099d5](https://github.com/crystina-z/pyserini/commit/7b099d534901d1f0161982605cd40d039ddb701d) using
```
encoder=castorini/mdpr-tied-pft-msmarco
index_dir=mdpr-dindex/$lang-$shard_id
mkdir -p $index_dir
python -m pyserini.encode input --corpus $corpus \
--fields title text \
--delimiter "\n\n" \
--shard-id $shard_id \
--shard-num $shard_num \
output --embeddings $index_dir \
--to-faiss \
encoder --encoder $encoder \
--fields title text \
--batch 128 \
--encoder-class 'auto' \
--fp16
```
Here's a sample retrieval command (on the test set):
```bash
set_name=test
python -m pyserini.dsearch \
--encoder castorini/mdpr-tied-pft-msmarco \
--topics mrtydi-v1.1-${lang}-${set_name} \
--index ${index_dir} \
--output runs/run.mrtydi-v1.1-$lang.${set_name}.txt \
--batch-size 36 \
--threads 12 \
--encoder-class 'auto'
```
