• Get BEIR and MSMARCO from BEIR Repo
• It is necessary to download BioASK from the original cite.
  • We prepare a script, prepare_bioask.py.

• Get Domain Corpus
  • PubMed
  • S2ORC
• Process the corpus. We prepare following scripts
  • proc_pubmed.py
  • proc_s2orc.py

$ cd adalm_scripts/run
$ bash add_new_vocab_all.sh
$ bash init_add_vocab_model_all.sh
$ bash run_mlm.sh <model_path> <path_to_outdir> <path_to_corpus_file>

• Please rewrite path in bash files.

$ cd /path/to/this/repo
$ cd training/run
$ bash train_splade_distil.sh <model_path> <output_dir>

• Please rewrite path in bash files.
• We prepare other bash files for training dense retrieval and GPL in the dir. If you experiment with them please check them.

$ cd /path/to/this/repo
$ cd search/run
$ bash search_splade.sh <beir_data_dir> <result_out_dir> <model_path>

• If you'd like to remove idf weight, change mode val from idf to org in the bash file.
• If you'd like to run splade-doc, please set d-idf or d-org in the bash file
• We prepare other bash files for search with dense retrieval and BM25. If you experiment with them please check them.
