• Abstract: Natural language is among the most accessible tools for explaining decisions to humans, and large pretrained language models (PLMs) have demonstrated impressive abilities to generate coherent natural language explanations (NLE). The existing NLE research perspectives do not take the audience into account. An NLE can have high textual quality, but it might not accommodate audiences' needs and preference. To address this limitation, we propose an alternative perspective, \textit{situated} NLE. On the evaluation side, we set up automated evaluation scores. These scores describe the properties of NLEs in lexical, semantic, and pragmatic categories. On the generation side, we identify three prompt engineering techniques and assess their applicability on the situations. Situated NLE provides a perspective and facilitates further research on the generation and evaluation of explanations.

• Scenarios and Approaches for Situated Natural Language Explanations [18.022428746019582]
  We collect a benchmarking dataset, Situation-Based Explanation. This dataset contains 100 explanandums. For each "explanandum paired with an audience" situation, we include a human-written explanation. We examine three categories of prompting methods: rule-based prompting, meta-prompting, and in-context learning prompting.

  State-of-the-art natural language processing (NLP) models are trained on massive training corpora, and report a superlative performance on evaluation datasets. This survey delves into an important attribute of these datasets: the dialect of a language. Motivated by the performance degradation of NLP models for dialectic datasets and its implications for the equity of language technologies, we survey past research in NLP for dialects in terms of datasets, and approaches.

  We aim to leverage the instruction-following and textual understanding capabilities of recent Large Language Models to facilitate causal explainability. We propose a three-step pipeline via which, we use an off-the-shelf LLM to identify the latent or unobserved features in the input text. We experiment with our pipeline on multiple NLP text classification datasets, and present interesting and promising findings.

  Explanations of neural models aim to reveal a model's decision-making process for its predictions. Recent work shows that current methods giving explanations such as saliency maps or counterfactuals can be misleading. This work explores the challenging question of evaluating the faithfulness of natural language explanations.

  We propose the Chain of Explanation Prompting method, inspired by the chain of thoughts study citewei2022chain, to generate high-quality NLE for implicit hate speech. We build a benchmark based on the selected mainstream Pre-trained Language Models (PLMs), with various evaluation metrics from lexical, semantic, and faithful aspects. To further evaluate the quality of the generated NLE from human perceptions, we hire human annotators to score the informativeness and clarity of the generated NLE.
