Abstract
Experience of the everyday language indicates the use of complicated reasonings both for people and the AI systems. Natural Language Inference (NLI) is the process of reasoning about inferential relationships, meaning to establish whether a hypothesis is a true (entailment), false (contradiction), or undetermined (neutral) given a premise. Previous works have generated inference corpora, such as the SNLI and the MNLI, which comprise only unstructured representations of text in the form of sentences in which relationships between words are explicitly expressed, and often need information extraction. However, text can also occur universally in other structured forms like tables, graphs, and databases.Building upon previous work on large-scale datasets for inference, we introduce a new dataset called INFOTABS, comprising of human-written textual hypotheses based on premises that are tables extracted from Wikipedia info-boxes. Our analysis shows that the semi-structured, multi-domain, and heterogeneous nature of the premises admits complex, multi-faceted reasoning. Experiments reveal that, while human annotators agree on the relationships between a table-hypothesis pair, several standard modeling strategies are unsuccessful at the task, suggesting that reasoning about tables can pose a new modeling challenge.
