摘要:

信息可视化(如条形图和折线图)在探索数据和传达见解方面非常受欢迎。对某些人来说,解释和理解这种可视化可能具有挑战性,例如那些视力受损或视觉素养低的人。在这项工作中,我们引入了一个新的数据集,并提出了一个神经模型自动生成图表的自然语言摘要。生成的摘要提供了对图表的解释,并传达了在该图表中发现的关键见解。我们的神经模型是通过扩展数据到文本生成任务的最先进模型开发的,该模型利用了基于transformer的编码器-解码器架构。我们发现,我们的方法在内容选择指标上远远优于基础模型(55.42% vs. 8.49%),并生成了更多信息,简洁和连贯的摘要。

英文摘要:

Information visualizations such as bar charts and line charts are very popular for exploring data and communicating insights. Interpreting and making sense of such visualizations can be challenging for some people, such as those who are visually impaired or have low visualization literacy. In this work, we introduce a new dataset and present a neural model for automatically generating natural language summaries for charts. The generated summaries provide an interpretation of the chart and convey the key insights found within that chart. Our neural model is developed by extending the state-of-the-art model for the data-to-text generation task, which utilizes a transformer-based encoder-decoder architecture. We found that our approach outperforms the base model on a content selection metric by a wide margin (55.42% vs. 8.49%) and generates more informative, concise, and coherent summaries.
