Doc2query T5 Base Msmarco

🚀 Doc2Query Model Based on T5-base

A Doc2Query model trained on MS MARCO for retrieval, document expansion, and translation tasks.

🚀 Quick Start

This is a Doc2Query model based on t5-base and trained on MS MARCO. It's a converted version (to pytorch format) of the checkpoint released by the original authors, and it's ready for use in pyterrier_doc2query.

💻 Usage Examples

Basic Usage

import pyterrier as pt
pt.init()
from pyterrier_doc2query import Doc2Query
doc2query = Doc2Query('macavaney/doc2query-t5-base-msmarco')

Advanced Usage

Transforming documents

import pandas as pd
doc2query(pd.DataFrame([
  {'docno': '0', 'text': 'Hello Terrier!'},
  {'docno': '1', 'text': 'Doc2Query expands queries with potentially relevant queries.'},
]))
# docno                                               text                                           querygen
#    0                                     Hello Terrier!  hello terrier what kind of dog is a terrier wh...

Indexing transformed documents

doc2query.append = True # append querygen to text
indexer = pt.IterDictIndexer('./my_index', fields=['text'])
pipeline = doc2query >> indexer
pipeline.index([
  {'docno': '0', 'text': 'Hello Terrier!'},
  {'docno': '1', 'text': 'Doc2Query expands queries with potentially relevant queries.'},
])

Expanding and indexing a dataset

dataset = pt.get_dataset('irds:vaswani')
pipeline.index(dataset.get_corpus_iter())

Widget Examples

• msmarco-passage: "The presence of communication amid scientific minds was equally important to the success of the Manhattan Project as scientific intellect was. The only cloud hanging over the impressive achievement of the atomic researchers and engineers is what their success truly meant; hundreds of thousands of innocent lives obliterated."
• msmarco-passage-v2: "0-60 Times - 0-60 | 0 to 60 Times & 1/4 Mile Times | Zero to 60 Car Reviews."
• antique: "A small group of politicians believed strongly that the fact that Saddam Hussien remained in power after the first Gulf War was a signal of weakness to the rest of the world, one that invited attacks and terrorism. Shortly after taking power with George Bush in 2000 and after the attack on 9/11, they were able to use the terrorist attacks to justify war with Iraq on this basis and exaggerated threats of the development of weapons of mass destruction. The military strength of the U.S. and the brutality of Saddam's regime led them to imagine that the military and political victory would be relatively easy."
