| # mrtydi-v1.1-thai | |
| Faiss flat index for Mr.TyDi v1.1 (Thai), using mDPR fine-tuned on NQ. | |
| This index was generated on 2022/02/07 at commit [5df364](https://github.com/castorini/pyserini/commit/5df3649b128ece125ce8a9171ed4001ce3a6ef23) on `narval` with the following command: | |
| ```bash | |
| lang=thai | |
| tarfn=mrtydi-v1.1-$lang.tar.gz | |
| encoder=models/mdpr-context-encoder | |
| corpus=mrtydi-v1.1-$lang/collection/docs.jsonl | |
| index_dir=mrtydi-mdpr-dindex/$lang | |
| wget https://git.uwaterloo.ca/jimmylin/mr.tydi/-/raw/master/data/$tarfn | |
| tar –xvf $tarfn | |
| gzip -cvf $corpus.gz > $corpus | |
| mkdir -p $index_dir | |
| python -m pyserini.encode input --corpus $corpus \ | |
| --fields title text \ | |
| --delimiter "\n\n" \ | |
| output --embeddings $index_dir \ | |
| --to-faiss \ | |
| encoder --encoder $encoder \ | |
| --fields title text \ | |
| --batch 128 \ | |
| --fp16 | |
| ``` | |
| Note that the delimiter was manually changed from "`\n`" into "`\n\n`" in `pyserini.encode`. | |
| This was later generalized into a command-line option in [Pyserini #1000](https://github.com/castorini/pyserini/pull/1000/commits/5021e12d1d2e1bc3d4015955bcf77076c5798ce6#diff-45356c3f5e9cd223bb23d7efea3f7ed834abbcd32f604eb7fdd138e364273241L104). | |
| Here's a sample retrieval command (on the test set): | |
| ```bash | |
| set_name=test | |
| python -m pyserini.dsearch \ | |
| --encoder castorini/mdpr-question-nq \ | |
| --topics mrtydi-v1.1-${lang}-${set_name} \ | |
| --index ${index_dir} \ | |
| --output runs/run.mrtydi-v1.1-$lang.${set_name}.txt | |
| --batch-size 36 \ | |
| --threads 12 | |
| ``` |
