项目摘要
The term "Google" has become a verb for most of us. Search engines, however, have certain limitations. For example ask it for the impact of the current global financial crisis in different parts of the world, and you can expect to sift through thousands of results for the answer. This motivates the research in complex question answering where the purpose is to create summaries of large volumes of information as answers to complex questions, rather than simply offering a listing of sources. Unlike simple questions, complex questions cannot be answered easily as they often require inferencing and synthesizing information from multiple documents. Inferencing and synthesizing information from multiple documents require extracting, organizing, and inter-relating the pieces of information contained in a set of relevant documents, in order to obtain a comprehensive, non redundant report that satisfies the information need. Answering complex questions can be seen as a topic-oriented, informative multi-document summarization where the goal is to produce a single text as a compressed version of a set of documents with a minimum loss of relevant information. This research proposal deals with ways in which text summarization and question answering technologies can be combined to form truly useful information delivery tools. More precisely, the problems that we are planning to investigate are: developing text summarization and question answering models that answer complex questions, building decomposition models that decompose complex questions into simple questions easy to answer, constructing models that generate questions automatically, capturing users' needs and tailoring the answers as summaries to user needs, and designing intelligent mechanisms to process natural language (i.e., inference, synthesize and summarize information) as well as mechanisms for coherent and tailored information delivery. I am planning to develop models, technologies and tools to deliver to users information that is relevant and appropriate for the users receiving it, information that they can easily assimilate to enable them to perform their tasks, usually enabling better and more efficient decision-making.
对我们大多数人来说,“谷歌”这个词已经变成了一个动词。然而,搜索引擎有一定的局限性。例如,如果问它当前全球金融危机对世界不同地区的影响,你可以预期从数千个结果中筛选出答案。这促使了对复杂问题回答的研究,其目的是创建大量信息的摘要作为对复杂问题的答案,而不是简单地提供来源列表。与简单的问题不同,复杂的问题不容易回答,因为它们通常需要从多个文档中推断和合成信息。从多个文档中推理和综合信息需要对一组相关文档中包含的信息进行提取、组织和相互关联,以获得满足信息需求的全面、无冗余的报告。回答复杂的问题可以被视为一种面向主题的、信息量大的多文档摘要,其目标是以最小的相关信息损失产生一组文档的压缩版本的单个文本。这项研究方案涉及如何将文本摘要和问答技术相结合,以形成真正有用的信息传递工具。更准确地说,我们计划研究的问题是:开发回答复杂问题的文本摘要和问答模型;构建将复杂问题分解为易于回答的简单问题的分解模型;构建自动生成问题的模型;捕获用户需求并根据用户需求定制答案作为摘要;设计智能机制来处理自然语言(即推理、合成和汇总信息)以及连贯和定制的信息传递机制。我计划开发模型、技术和工具,向用户提供与接收信息的用户相关和适当的信息,他们可以很容易地吸收这些信息,使他们能够执行任务,通常能够更好和更有效地进行决策。
