BordIRLines Dataset

This is the dataset associated with the paper "BordIRlines: A Dataset for Evaluating Cross-lingual Retrieval-Augmented Generation" (link).

Dataset Summary

The BordIRLines Dataset is an information retrieval (IR) dataset constructed from various language corpora. It contains queries and corresponding ranked docs along with their relevance scores. The dataset includes multiple languages, including English, Arabic, Spanish, and others, and is split across different sources like LLM-based outputs. Each doc is a passage from a Wikipedia article.

Languages

The dataset includes docs and queries in the following languages:

• en: English
• zht: Traditional Chinese
• ar: Arabic
• zhs: Simplified Chinese
• es: Spanish
• fr: French
• ru: Russian
• hi: Hindi
• ms: Malay
• sw: Swahili
• az: Azerbaijani
• ko: Korean
• pt: Portuguese
• hy: Armenian
• th: Thai
• uk: Ukrainian
• ur: Urdu
• sr: Serbian
• iw: Hebrew
• ja: Japanese
• hr: Croatian
• tl: Tagalog
• ky: Kyrgyz
• vi: Vietnamese
• fa: Persian
• tg: Tajik
• mg: Malagasy
• nl: Dutch
• ne: Nepali
• uz: Uzbek
• my: Burmese
• da: Danish
• dz: Dzongkha
• id: Indonesian
• is: Icelandic
• tr: Turkish
• lo: Lao
• sl: Slovenian
• so: Somali
• mn: Mongolian
• bn: Bengali
• bs: Bosnian
• ht: Haitian Creole
• el: Greek
• it: Italian
• to: Tonga
• ka: Georgian
• sn: Shona
• sq: Albanian
• control: see below

The control language is English, and contains the queries for all 251 territories. In contrast, en is only the 38 territories which have an English-speaking claimant.

Systems

We have processed retrieval results for these IR systems:

• openai: OpenAI's model text-embedding-3-large, cosine similarity
• m3: M3-embedding (link) (Chen et al., 2024)

Modes

Considering a user query in language l on a territory t, there are 4 modes for the IR.

• qlang: consider passages in {l}. This is monolingual IR (the default).
• qlang_en: consider passages in either {l, en}.
• en: consider passages in {en}.
• rel_langs: consider passages in all relevant languages to t + en, so {l1, l2, ..., en}. This is a set, so en will not be duplicated if it already is relevant.

Dataset Structure

Data Fields

The dataset consists of the following fields:

• query_id (string): The id of the query.
• query (string): The query text as provided by the queries.tsv file.
• territory (string): The territory of the query hit.
• rank (int32): The rank of the document for the corresponding query.
• score (float32): The relevance score of the document as provided by the search engine or model.
• doc_id (string): The unique identifier of the article.
• doc_text (string): The full text of the corresponding article or document.

Download Structure

The dataset is structured as follows:

data/
  {lang}/
    {system}/
      {mode}/
        {lang}_query_hits.tsv
...
  all_docs.json
  queries.tsv

• queries.tsv: Contains the list of query IDs and their associated query texts.
• all_docs.json: JSON dict containing all docs. It is organized as a nested dict, with keys lang, and values another dict with keys doc_id, and values doc_text.
• {lang}\_query_hits.tsv: A TSV file with relevance scores and hit ranks for queries.

Currently, there are 50 langs * 1 system * 4 modes = 200 query hit TSV files.

Example Usage

from datasets import load_dataset

# load DatasetDict with all 4 modes, for control language, 10 hits
dsd_control = load_dataset("borderlines/bordirlines", "control")

# load Dataset for English, with rel_langs mode, 50 hits
ds_oa_en = load_dataset("borderlines/bordirlines", "en", split="openai.rel_langs", n_hits=50)
# load Dataset for Simplified Chinese, en mode
ds_oa_zhs1 = load_dataset("borderlines/bordirlines", "zhs", split="openai.en")
# load Dataset for Simplified Chinese, qlang mode
ds_oa_zhs2 = load_dataset("borderlines/bordirlines", "zhs", split="openai.qlang")


# load Dataset for Simplified Chinese, en mode, m3 embedding
ds_m3_zhs1 = load_dataset("borderlines/bordirlines", "zhs", split="m3.en")
# load Dataset for Simplified Chinese, qlang mode, m3 embedding
ds_m3_zhs2 = load_dataset("borderlines/bordirlines", "zhs", split="m3.qlang")
