Query: AM2iCo: Evaluating Word Meaning in Context across Low-Resource Languages
  with Adversarial Examples   Capturing word meaning in context and distinguishing between correspondences
and variations across languages is key to building successful multilingual and
cross-lingual text representation models. However, existing multilingual
evaluation datasets that evaluate lexical semantics "in-context" have various
limitations. In particular, 1) their language coverage is restricted to
high-resource languages and skewed in favor of only a few language families and
areas, 2) a design that makes the task solvable via superficial cues, which
results in artificially inflated (and sometimes super-human) performances of
pretrained encoders, on many target languages, which limits their usefulness
for model probing and diagnostics, and 3) little support for cross-lingual
evaluation. In order to address these gaps, we present AM2iCo (Adversarial and
Multilingual Meaning in Context), a wide-coverage cross-lingual and
multilingual evaluation set; it aims to faithfully assess the ability of
state-of-the-art (SotA) representation models to understand the identity of
word meaning in cross-lingual contexts for 14 language pairs. We conduct a
series of experiments in a wide range of setups and demonstrate the challenging
nature of AM2iCo. The results reveal that current SotA pretrained encoders
substantially lag behind human performance, and the largest gaps are observed
for low-resource languages and languages dissimilar to English.
