Translation Tables for Probablistic Structured Queries

This repository contains the raw translation tables for tha package fast_psq. Please refer to the GitHub for more information. The following is a brief example for using the tables.

Get started

fast_psq is available on PyPI.

pip install fast_psq ir_datasets ir_measures

The following is an example indexing command.

python -m fast_psq.index \
--doc_file irds:neuclir/1/zh/trec-2022 \
--lang zh \
--psq_file hltcoe/psq_translation_tables:zh.table.dict.gz \
--min_translation_prob 0.00010 \
--max_translation_alternatives 64 \
--max_translation_cdf 0.99 \
--docid doc_id \
--title title \
--body text \
--min_translation_prob 1e-4 \
--max_translation_alternatives 64 \
--output_dir ./indexes/neuclir-zh.f32/ \
--compression \
--nworkers 64

The following command is an example for searching.

python -m fast_psq.search \
--query_source irds:neuclir/1/zh/trec-2022 \
