Lexical Semantic Change (LSC) provides insight into cultural and social dynamics. Yet, the validity of methods for measuring different kinds of LSC remains unestablished due to the absence of historical benchmark datasets. To address this gap, we propose LSC-Eval, a novel three-stage general-purpose…
Historical linguists have identified multiple forms of lexical semantic change. We present a three-dimensional framework for integrating these forms and a unified computational methodology for evaluating them concurrently. The dimensions represent increases or decreases in semantic 1) sentiment (val…

On one hand, intuition and some prior work suggest that accuracy and fluency should trade off against each other,…

Translation difficulty can be measured by recording the diversity of responses provided by human translators and the time taken to provide these responses, but these beha…
