Setup the env

conda create -n kilt37 -y python=3.7 && conda activate kilt37
pip install -e .

KILT knowledge source

The KILT knowledge source can be downloaded here: kilt_knowledgesource.json (34.76GiB).<br> It is based on the 2019/08/01 Wikipedia dump.<br> We use mongoDB to index the knowledge base (but you can use any json-based db).<br> To import the knowledge source in mongoDB run:

wget http://dl.fbaipublicfiles.com/KILT/kilt_knowledgesource.json
mongoimport --db kilt --collection knowledgesource --file kilt_knowledgesource.json

Structure of each record

{
 'wikipedia_title': 'Email marketing',
 'wikipedia_id': 1101759, 
 'text': ['p1', 'p2',...., 'pn'], # list of paragraph text
 'anchors': [{"text":,"href":,"paragraph_id":,"start":,"end":} ]  , 
 'categories': 'comma separated list of categories'
 'history': # some info from wikipedia, including original url
 'wikidata_info': # wikidata info
 }

Query the knowledge source

from kilt.knowledge_source import KnowledgeSource

# get the knowledge souce
ks = KnowledgeSource()

# count entries - 5903530
ks.get_num_pages()

# get page by id
page = ks.get_page_by_id(27097632)

# get pages by title
page = ks.get_page_by_title("Michael Jordan")

KILT data

Examples:

download the data

mkdir data
python scripts/download_all_kilt_data.py
python scripts/get_triviaqa_input.py

You can also download and use the KILT data through the HuggingFace's nlp library.

Note that we release only the input for the test sets, without answers. Test answers are used for the KILT challenge on EvalAI where participants can upload their models’ predictions and be listed on the public leaderboard (there are strict submission limits to discourage overfitting on test data).

KILT data format

{'id': # original data point id if available otherwise unique id
 'input': # question / claim / sentence / etc
 'output': [ # each element might contain an answer, a provenance or both
    {
    'answer': # answer in textual form
    'provenance': [
        # evidence set for the answer from the KILT ks
        {
            'wikipedia_id':  # *mandatory* 
            'title': 
            'section': 
            'start_paragraph_id': 
            'start_character': 
            'end_paragraph_id':
            'end_character': 
            'bleu_score': # wrt original evidence
            'meta': # dataset/task specific
        }
        ] 
      }
    ]
 'meta': # dataset/task specific
 }

KILT data catalogue

^* run python scripts/get_triviaqa_input.py to get the question associated with each id

Additional data

For Entity Linking, in addition to the AIDA CoNLL-YAGO train set, the whole knowledge source can be used as training data by exploiting hyperlinks. To facilitate experimentation, we release such data in KILT format following the splits of BLINK:

• blink-train-kilt.jsonl (9M lines)
• blink-dev-kilt.jsonl (10,000 lines)

We also provide a script to map the TAC-KBP 2010 dataset to the knowledge source and format of KILT.

Run the retrieval evaluation

Please follow this README.

Mapping scripts

Mapping scripts are located in kilt/datasets/. See scripts/map_datasets.py for an example.

Troubleshooting

If the module cannot be found, preface the python command with PYTHONPATH=.

If the experiments fail on GPU memory allocation, try reducing batch size.
