This repository contains a fork of the original UniIR codebase, modified for easy Pyserini integration and repackaged as a PyPI package.

current_version = "0.1.2"

Installation

Install the package directly from PyPI:

pip install uniir-for-pyserini

Or, install from source:

git clone https://github.com/castorini/UniIR-for-Pyserini.git
cd UniIR-for-Pyserini
pip install .

Then, install the CLIP model:

pip install git+https://github.com/openai/CLIP.git

Quick Start

The following code snippet shows how UniIR models can be used with Pyserini's encoding and indexing pipeline. In this example, clip-sf-large model is used to encode the cirr_task7 corpus into dense vector representations. Similar steps can be done for on-the-fly query encoding using the QueryEncoder.

For full compatible use and features, please use/refer to these wrapper classes in Pyserini.

# Encoding and Indexing Steps
from pyserini.encode import JsonlCollectionIterator
from pyserini.encode.optional import FaissRepresentationWriter
from uniir_for_pyserini.uniir_corpus_encoder import CorpusEncoder

MBEIR_FIELDS = ['img_path', 'txt', 'modality', 'did']

mbeir_corpus_encoder = CorpusEncoder("clip_sf_large")

collection_iterator = JsonlCollectionIterator(  
    'collections/M-BEIR/mbeir_cirr_task7_cand_pool.jsonl',  
    fields=MBEIR_FIELDS,
    docid_field='did'
)

embedding_writer = FaissRepresentationWriter(
    'indexes/cirr.clip-sf-large'
)

with embedding_writer:
    for batch_info in collection_iterator(32):
        kwargs = {'fp16': True}
        for field_name in MBEIR_FIELDS:
            kwargs[f'{field_name}s'] = batch_info[field_name] 
        
        embeddings = mbeir_corpus_encoder.encode(**kwargs)
        batch_info['vector'] = embeddings
        embedding_writer.write(batch_info, MBEIR_FIELDS) 

# Searching Step
from pyserini.search.faiss import FaissSearcher
from pyserini.query_iterator import MBEIRQueryIterator
from uniir_for_pyserini.uniir_query_encoder import QueryEncoder

mbeir_query_encoder = QueryEncoder("clip_sf_large")

searcher = FaissSearcher(  
        'indexes/cirr.clip-sf-large',
        mbeir_query_encoder  
    )

query_iterator = MBEIRQueryIterator.from_topics('mbeir_cirr_task7_test.jsonl')

results = {}    
for qid, query_data in query_iterator:  
    # query_data now contains the structured M-BEIR format:  
    # {'qid', 'query_txt', 'query_img_path', 'query_modality', 'pos_cand_list'}  
      
    hits = searcher.search(query_data, k=1000) 
    results[qid] = [(hit.docid, hit.score) for hit in hits]

Available Models

Note: L2 Norm isn't applied during encoding because it is applied in the UniIR wrapper classes in Pyserini

This package supports the following UniIR models from the TIGER-Lab UniIR Hugging Face Hub:

• clip_sf_large
• blip_ff_large
