• Title: Variationist: Exploring Multifaceted Variation and Bias in Written Language Data
• Authors: Alan Ramponi, Camilla Casula, Stefano Menini,
• Abstract summary: Exploring and understanding language data is a fundamental stage in all areas dealing with human language. Yet, there is currently a lack of a unified, customizable tool to seamlessly inspect and visualize language variation and bias. In this paper, we introduce Variationist, a highly-modular, descriptive, and task-agnostic tool that fills this gap.

• Abstract: Exploring and understanding language data is a fundamental stage in all areas dealing with human language. It allows NLP practitioners to uncover quality concerns and harmful biases in data before training, and helps linguists and social scientists to gain insight into language use and human behavior. Yet, there is currently a lack of a unified, customizable tool to seamlessly inspect and visualize language variation and bias across multiple variables, language units, and diverse metrics that go beyond descriptive statistics. In this paper, we introduce Variationist, a highly-modular, extensible, and task-agnostic tool that fills this gap. Variationist handles at once a potentially unlimited combination of variable types and semantics across diversity and association metrics with regards to the language unit of choice, and orchestrates the creation of up to five-dimensional interactive charts for over 30 variable type-semantics combinations. Through our case studies on computational dialectology, human label variation, and text generation, we show how Variationist enables researchers from different disciplines to effortlessly answer specific research questions or unveil undesired associations in language data. A Python library, code, documentation, and tutorials are made publicly available to the research community.

  Deception, a prevalent aspect of human communication, has undergone a significant transformation in the digital age. Recent studies have shown the possibility of the existence of universal linguistic cues to deception across domains within the English language. The practical task of deception detection in low-resource languages is not a well-studied problem due to the lack of labeled data.

  We present a suite of experiments that allow us to understand the underlying challenges of language model adaptation to nonstandard text. We do so by designing interventions that approximate several types of linguistic variation and their interactions with existing biases of language models. Applying our interventions during language model adaptation with varying size and nature of training data, we gain important insights into when knowledge transfer can be successful.

  In cross-lingual language models, representations for many different languages live in the same space. We compute a task-based measure of cross-lingual alignment in the form of bitext retrieval performance. We examine a range of linguistic, quasi-linguistic, and training-related features as potential predictors of these alignment metrics.

  We propose a new approach called Cross-lingual Language Projection (XLP) to replace language embedding. XLP projects the word embeddings into language-specific semantic space, and then the projected embeddings will be fed into the Transformer model. Experiments show that XLP can freely and significantly boost the model performance on extensive multilingual benchmark datasets.
