• Title: When is Wall a Pared and when a Muro? -- Extracting Rules Governing Lexical Selection
• Authors: Aditi Chaudhary, Kayo Yin, Antonios Anastasopoulos, Graham Neubig
• Abstract summary: We present a method for automatically identifying fine-grained lexical distinctions. We extract concise descriptions explaining these distinctions in a human- and machine-readable format. We use these descriptions to teach non-native speakers when to translate a given ambiguous word into its different possible translations.

• Abstract: Learning fine-grained distinctions between vocabulary items is a key challenge in learning a new language. For example, the noun "wall" has different lexical manifestations in Spanish -- "pared" refers to an indoor wall while "muro" refers to an outside wall. However, this variety of lexical distinction may not be obvious to non-native learners unless the distinction is explained in such a way. In this work, we present a method for automatically identifying fine-grained lexical distinctions, and extracting concise descriptions explaining these distinctions in a human- and machine-readable format. We confirm the quality of these extracted descriptions in a language learning setup for two languages, Spanish and Greek, where we use them to teach non-native speakers when to translate a given ambiguous word into its different possible translations. Code and data are publicly released here (https://github.com/Aditi138/LexSelection)

• Crowdsourcing Lexical Diversity [7.569845058082537]
  This paper proposes a novel crowdsourcing methodology for reducing bias in lexicons. Crowd workers compare lexemes from two languages, focusing on domains rich in lexical diversity, such as kinship or food. We validated our method by applying it to two case studies focused on food-related terminology.

  This paper investigates biases of Large Language Models (LLMs) through the lens of grammatical gender. We prompt a model to describe nouns with adjectives in various languages, focusing specifically on languages with grammatical gender. We find that a simple classifier can not only predict noun gender above chance but also exhibit cross-language transferability.

  We show that a neural network language model can learn restrictions to the passive that are similar to those displayed by humans. We find that while the frequency with which a verb appears in the passive significantly affects its passivizability, the semantics of the verb does not.

  We present an automatic framework that automatically discovers and visualizing descriptions of different aspects of grammar. Specifically, we extract descriptions from a natural text corpus that answer questions about morphosyntax and semantics. We apply this method for teaching the Indian languages, Kannada and Marathi, which, unlike English, do not have well-developed pedagogical resources.

  We describe the University of Alberta systems for the SemEval-2022 Task 2 on multilingual idiomaticity detection. Under the assumption that idiomatic expressions are noncompositional, our first method integrates information on the meanings of the individual words of an expression into a binary classifier. Our second method translates an expression in context, and uses a lexical knowledge base to determine if the translation is literal.

  We propose an automatic framework that aims to ease linguists' discovery and extraction of concise descriptions of linguistic phenomena. Specifically, we apply this framework to extract descriptions for three phenomena: morphological agreement, case marking, and word order. We evaluate the descriptions with the help of language experts and propose a method for automated evaluation when human evaluation is infeasible.

• Speakers Fill Lexical Semantic Gaps with Context [65.08205006886591]
  We operationalise the lexical ambiguity of a word as the entropy of meanings it can take. We find significant correlations between our estimate of ambiguity and the number of synonyms a word has in WordNet. This suggests that, in the presence of ambiguity, speakers compensate by making contexts more informative.
