VAT is automatically created by a novel variance-aware filtering method that filters the indiscriminative test instances of the current MT benchmark without any human labor. Experimental results show that VAT outperforms the original WMT benchmark in terms of the correlation with human judgment across mainstream language pairs and test sets. Further analysis on the properties of VAT reveals the challenging linguistic features (e.g., translation of low-frequency words and proper nouns) for the competitive MT systems, providing guidance for constructing future MT test sets. **Disclaimer**: *The VAT test sets are hosted through Github by the [Natural Language Processing & Portuguese-Chinese Machine Translation Laboratory (NLP2CT Lab)](http://nlp2ct.cis.um.edu.mo/) of the University of Macau. They were introduced by the paper [Variance-Aware Machine Translation Test Sets](https://openreview.net/forum?id=hhKA5k0oVy5) by [Runzhe Zhan](https://runzhe.me/), [Xuebo Liu](https://sunbowliu.github.io/), [Derek F. Wong](https://www.fst.um.edu.mo/personal/derek-wong/), [Lidia S. Chao](https://aclanthology.org/people/l/lidia-s-chao/) and follow the original licensing for WMT test sets. ### Supported Tasks and Leaderboards #### Machine Translation Refer to the [original paper](https://openreview.net/forum?id=hhKA5k0oVy5) for additional details on model evaluation on VAT. ### Languages The following table taken from the original paper lists the languages supported by the VAT test sets, for a total of 70 language pairs: | ↔️ | wmt16 | wmt17 | wmt18 | wmt19 | wmt20 | |----------:|:--------|:--------|:--------|--------:|--------:| | xx_en | cs,de,fi,

E.g. to load the English-Russian test set from wmt16, use load_dataset('gsarti/wmt_vat', 'wmt16_en_ru'). ## Dataset Structure ### Data Instances A sample from the test split (the only available split) for the WMT16 English-Russian language (wmt16_en_ru config) is provided below. All configurations have the same structure. python { 'orig_id': 0, 'source': 'The social card of residents of Ivanovo region is to be recognised as an electronic payment instrument.', 'reference': 'Социальная карта жителя Ивановской области признается электронным средством платежа.' }  The text is provided as-in the original dataset, without further preprocessing or tokenization. ### Data Fields - orig_id: Id corresponding to the row id in the original dataset, before variance-aware filtering. - source: The source sentence. - reference: The reference sentence in the target language. ### Data Splits Taken from the original repository: | Configuration | # Sentences | # Words | # Vocabulary | | :-----------: | :--------: | :-----: | :--------------: | | wmt20_km_en | 928 | 17170 | 3645 | | wmt20_cs_en | 266 | 12568 | 3502 | | wmt20_en_de | 567 | 21336 | 5945 | | wmt20_ja_en | 397 | 10526 | 3063 | | wmt20_ps_en | 1088 | 20296 | 4303 | | wmt20_en_zh | 567 | 18224 | 5019 | | wmt20_en_ta | 400 | 7809 | 4028 | | wmt20_de_en | 314 | 16083 | 4046 | | wmt20_zh_en | 800 | 35132 | 6457 | | wmt20_en_ja | 400 | 12718 | 2969 | | wmt20_en_cs | 567 | 16579 | 6391 | | wmt20_en_pl | 400 | 8423 | 3834 | | wmt20_en_ru | 801 | 17446 | 6877 | | wmt20_pl_en | 400 | 7394 | 2399 | | wmt20_iu_en | 1188 | 23494 | 3876 | | wmt20_ru_en | 396 | 6966 | 2330 | | wmt20_ta_en | 399 | 7427 | 2148 | | wmt19_zh_en | 800 | 36739 | 6168 | | wmt19_en_cs | 799 | 15433 | 6111 | | wmt19_de_en | 800 | 15219 | 4222 | | wmt19_en_gu | 399 | 8494 | 3548 | | wmt19_fr_de | 680 | 12616 | 3698 | | wmt19_en_zh | 799 | 20230 | 5547 | | wmt19_fi_en | 798 | 13759 | 3555 | | wmt19_en_fi | 799 | 13303 | 6149 | | wmt19_kk_en | 400 | 9283 | 2584 | | wmt19_de_cs | 799 | 15080 | 6166 | | wmt19_lt_en | 400 | 10474 | 2874 | | wmt19_en_lt | 399 | 7251 | 3364 | | wmt19_ru_en | 800 | 14693 | 3817 | | wmt19_en_kk | 399 | 6411 | 3252 | | wmt19_en_ru | 799 | 16393 | 6125 | | wmt19_gu_en | 406 | 8061 | 2434 | | wmt19_de_fr | 680 | 16181 | 3517 | | wmt19_en_de | 799 | 18946 | 5340 | | wmt18_en_cs | 1193 | 19552 | 7926 | | wmt18_cs_en | 1193 | 23439 | 5453 | | wmt18_en_fi | 1200 | 16239 | 7696 | | wmt18_en_tr | 1200 | 19621 | 8613 | | wmt18_en_et | 800 | 13034 | 6001 | | wmt18_ru_en | 1200 | 26747 | 6045 | | wmt18_et_en | 800 | 20045 | 5045 | | wmt18_tr_en | 1200 | 25689 | 5955 | | wmt18_fi_en | 1200 | 24912 | 5834 | | wmt18_zh_en | 1592 | 42983 | 7985 | | wmt18_en_zh | 1592 | 34796 | 8579 | | wmt18_en_ru | 1200 | 22830 | 8679 | | wmt18_de_en | 1199 | 28275 | 6487 | | wmt18_en_de | 1199 | 25473 | 7130 | | wmt17_en_lv | 800 | 14453 | 6161 | | wmt17_zh_en | 800 | 20590 | 5149 | | wmt17_en_tr | 1203 | 17612 | 7714 | | wmt17_lv_en | 800 | 18653 | 4747 | | wmt17_en_de | 1202 | 22055 | 6463 | | wmt17_ru_en | 1200 | 24807 | 5790 | | wmt17_en_fi | 1201 | 17284 | 7763 | | wmt17_tr_en | 1203 | 23037 | 5387 | | wmt17_en_zh | 800 | 18001 | 5629 | | wmt17_en_ru | 1200 | 22251 | 8761 | | wmt17_fi_en | 1201 | 23791 | 5300 | | wmt17_en_cs | 1202 | 21278 | 8256 | | wmt17_de_en | 1202 | 23838 | 5487 | | wmt17_cs_en | 1202 | 22707 | 5310 | | wmt16_tr_en | 1200 | 19225 | 4823 | | wmt16_ru_en | 1199 | 23010 | 5442 | | wmt16_ro_en | 800 | 16200 | 3968 | | wmt16_de_en | 1200 | 22612 | 5511 | | wmt16_en_ru | 1199 | 20233 | 7872 | | wmt16_fi_en | 1200 | 20744 | 5176 | | wmt16_cs_en | 1200 | 23235 | 5324 | ### Dataset Creation The dataset was created by retaining a subset of the top 40% instances from various WMT test sets for which the variance between automatic scores (BLEU, BLEURT, COMET, BERTScore) was the highest.
