• Abstract summary: CIDER -- a manually curated dataset -- contains dyadic dialogue explanations in the form of implicit and explicit knowledge triplets inferred using commonsense inference. We set up three different tasks conditioned on the dataset: Dialogue-level Natural Language Inference, Span Extraction, and Multi-choice Span Selection. Results obtained with transformer-based models reveal that the tasks are difficult, paving the way for promising future research.

• Abstract: Commonsense inference to understand and explain human language is a fundamental research problem in natural language processing. Explaining human conversations poses a great challenge as it requires contextual understanding, planning, inference, and several aspects of reasoning including causal, temporal, and commonsense reasoning. In this work, we introduce CIDER -- a manually curated dataset that contains dyadic dialogue explanations in the form of implicit and explicit knowledge triplets inferred using contextual commonsense inference. Extracting such rich explanations from conversations can be conducive to improving several downstream applications. The annotated triplets are categorized by the type of commonsense knowledge present (e.g., causal, conditional, temporal). We set up three different tasks conditioned on the annotated dataset: Dialogue-level Natural Language Inference, Span Extraction, and Multi-choice Span Selection. Baseline results obtained with transformer-based models reveal that the tasks are difficult, paving the way for promising future research. The dataset and the baseline implementations are publicly available at https://github.com/declare-lab/CIDER.

• Can Language Models Take A Hint? Prompting for Controllable Contextualized Commonsense Inference [12.941933077524919]
  We introduce "hinting," a data augmentation technique that enhances contextualized commonsense inference. "Hinting" employs a prefix prompting strategy using both hard and soft prompts to guide the inference process. Our results show that "hinting" does not compromise the performance of contextual commonsense inference while offering improved controllability.

  Reasoning over spans of tokens from different parts of the input is essential for natural language understanding. We introduce SpanEx, a dataset of human span interaction explanations for two NLU tasks: NLI and FC. We then investigate the decision-making processes of multiple fine-tuned large language models in terms of the employed connections between spans.

  This paper systematically inspects ChatGPT's performance in two discourse analysis tasks: topic segmentation and discourse parsing. ChatGPT demonstrates proficiency in identifying topic structures in general-domain conversations yet struggles considerably in specific-domain conversations. Our deeper investigation indicates that ChatGPT can give more reasonable topic structures than human annotations but only linearly parses the hierarchical rhetorical structures.

  Contextualized or discourse aware commonsense inference is the task of generating coherent commonsense assertions. Some problems with the task are: lack of controllability for topics of the inferred facts; lack of commonsense knowledge during training. We develop techniques to address the aforementioned problems in the task.

  We tackle conversational passage retrieval (ConvPR) with query reformulation integrated into a multi-stage ad-hoc IR system. We propose two conversational query reformulation (CQR) methods: (1) term importance estimation and (2) neural query rewriting. For the former, we expand conversational queries using important terms extracted from the conversational context with frequency-based signals. For the latter, we reformulate conversational queries into natural, standalone, human-understandable queries with a pretrained sequence-tosequence model.
