RuBLiMP

Dataset Description

RuBLiMP, or Russian Benchmark of Linguistic Minimal Pairs, is the first diverse and large-scale benchmark of minimal pairs in Russian.

RuBLiMP includes 45k minimal pairs of sentences that differ in grammaticality and isolate morphological, syntactic, or semantic phenomena. In contrast to existing benchmarks of linguistic minimal pairs, RuBLiMP is created by applying linguistic perturbations to automatically annotated sentences from open text corpora and decontaminating test data, making the minimal pairs more diverse and natural.

Dataset Creation

Example: Vpervye kosmonavt spal v nevesomosti "For the first time an astronaut slept in zero gravity".

The RuBLiMP's creation approach comprises four stages:

• (a) Extract sentences from publicly available corpora of Wikipedia texts, news articles, and books.
• (b) Annotate each extracted sentence in the Universal Dependencies scheme with a multidomain morphosyntactic parser for Russian.
• (c) Search the dependency trees for specific lexical units and linguistic structures and apply expert-written perturbation rules to create a pool of minimal pairs for a target paradigm.
• (d) Compute Min-K% Prob for each grammatical sentence in the pool using a set of LMs. Select t (the threshold for the maximum Min-K% Prob value), which allows to find an intersection of 1k minimal pairs between the LMs. The minimal pairs in the intersection contain grammatical sentences that are not detected as the LMs' pretraining examples.

Dataset Structure

Data Instances

Each instance in the dataset is pair of sentences, where a certain linguistic phenomenon is isolated:

{
    'id': 240907, 
    'source_sentence': 'Это еще вчера все поняли.', 
    'target_sentence': 'Это еще завтра все поняли.', 
    'source_word': 'вчера', 
    'target_word': 'завтра', 
    'level': 'Semantics', 
    'phenomenon': 'Tense', 
    'PID': 'tense_marker',
    'subtype': 'tense_marker_simple',
    'domain': 'librusec',
    'tree_length': 2
}

An example in English for illustration purposes:

{
    'id': 240907, 
    'source_sentence': 'Everyone understood this yesterday already.', 
    'target_sentence': 'Everyone understood this tomorrow already.', 
    'source_word': 'yesterday', 
    'target_word': 'tomorrow', 
    'level': 'Semantics', 
    'phenomenon': 'Tense', 
    'PID': 'tense_marker',
    'subtype': 'tense_marker_simple',
    'domain': 'librusec',
    'tree_length': 2
}
