多文档摘要(MDS)的目的是为每个给定的查询提取与一组文档中存在的不同查询相关的主题相关的压缩信息。许多方法分两个步骤进行。首先从集合中识别主题，然后通过提取每个识别的主题的不同文档中的显著句子来形成摘要。在这些方法中，基于潜在语义分析(LSA)的方法依赖于谱分解技术来识别主题。在这篇文章中，我们提出了依赖于量子信息访问(QIA)框架的这些技术的主要扩展。后者是基于量子物理的概率形式论开发的用于对信息访问进行建模的框架。QIA框架不仅指出了当前基于LSA的方法的局限性，而且激发了一个新的原则性标准来处理多文档摘要，以解决这些局限性。作为副产品，它还提供了一种增强基于LSA的方法的方法。在DUC 2005、2006和2007数据集上的大量实验表明，所提出的方法始终优于基于LSA的方法和参加DUC年度比赛的系统。这总体上表明了量子启发的信息获取方法的潜在影响，特别是卡塔尔投资局框架的影响。©2012 Wiley期刊，Inc.
Multidocument summarization (MDS) aims for each given query to extract compressed and relevant information with respect to the different query-related themes present in a set of documents. Many approaches operate in two steps. Themes are first identified from the set, and then a summary is formed by extracting salient sentences within the different documents of each of the identified themes. Among these approaches, latent semantic analysis (LSA) based approaches rely on spectral decomposition techniques to identify the themes. In this article, we propose a major extension of these techniques that relies on the quantum information access (QIA) framework. The latter is a framework developed for modeling information access based on the probabilistic formalism of quantum physics. The QIA framework not only points out the limitations of the current LSA-based approaches, but motivates a new principled criterium to tackle multidocument summarization that addresses these limitations. As a byproduct, it also provides a way to enhance the LSA-based approaches. Extensive experiments on the DUC 2005, 2006 and 2007 datasets show that the proposed approach consistently improves over both the LSA-based approaches and the systems that competed in the yearly DUC competitions. This demonstrates the potential impact of quantum-inspired approaches to information access in general, and of the QIA framework in particular. © 2012 Wiley Periodicals, Inc.
