Re-Implementation of SPARTA: Efficient Open-Domain Question Answering via Sparse Transformer Matching Retrieval. It is the re-implementation we used for BEIR: A Heterogenous Benchmark for Zero-shot Evaluation of Information Retrieval Models.
Also have a look at our BEIR repository: https://github.com/UKPLab/beir
Note: Sorry, this is just research code, it is not in the best shape. It is sadly also not well documented.
pip install sentence-transformers==1.2.1See train_sparta_msmarco.py how to train it on the MSMARCO Passage Ranking dataset. Note, you find the needed training files there. Download them and put them in a data/ folder.
See eval_msmarco.py how to evaluate a SPARTA model on the MSMARCO Passage Ranking dataset.
We provide a pre-trained model here: https://huggingface.co/BeIR/sparta-msmarco-distilbert-base-v1
See BEIR: A Heterogenous Benchmark for Zero-shot Evaluation of Information Retrieval Models how well our SPARTA implementation performs across several retrieval tasks.
