摘要:

在这项工作中,我们专注于检索相关参数的查询索赔涵盖不同方面的问题。现有技术的方法依赖于声明和前提之间的显式映射,因此无法在没有费力且昂贵的手动注释的情况下利用大量可用的前提集合。他们的多样性方法依赖于通过聚类去除重复,这并不能直接确保所选择的前提覆盖所有方面。这项工作介绍了一个新的多步骤的方法,参数检索问题。我们的方法不依赖于地面实况分配,而是采用机器学习模型来捕获参数之间的语义关系。除此之外,它旨在覆盖查询的各个方面,而不是试图显式地识别重复项。我们的实证评估表明,我们的方法导致显着改善的论点检索任务,即使它需要更少的数据。

英文摘要:

In this work, we focus on the problem of retrieving relevant arguments for a query claim covering diverse aspects. State-of-the-art methods rely on explicit mappings between claims and premises, and thus are unable to utilize large available collections of premises without laborious and costly manual annotation. Their diversity approach relies on removing duplicates via clustering which does not directly ensure that the selected premises cover all aspects. This work introduces a new multi-step approach for the argument retrieval problem. Rather than relying on ground-truth assignments, our approach employs a machine learning model to capture semantic relationships between arguments. Beyond that, it aims to cover diverse facets of the query, instead of trying to identify duplicates explicitly. Our empirical evaluation demonstrates that our approach leads to a significant improvement in the argument retrieval task even though it requires less data.
