我们提出并评估了一种方法,用于获得更准确的搜索结果,在可扩展标记语言(XML)的片段搜索,这是一个搜索,只产生相关的片段或部分的XML文档。现有的方法生成一个排名列表中的降序每个XML片段的相关性的搜索查询,但是,这些方法往往提取不相关的XML片段,忽略了更多的相关片段。为了解决这些问题,我们的方法提取相关的XML片段,考虑片段的大小和片段之间的关系。接下来,我们对XML片段进行评分,以生成一个精确的排名列表。为了评分,我们将为用户信息需求提供信息的XML片段排在列表的最高位置。特别是,每个XML片段的得分使用其后代和祖先XML fragments.Our实验评估表明,所提出的方法优于BM 25 E,传统的方法,既不重建XML片段,也不使用后代和祖先的统计。
We propose and evaluate a method for obtaining more accurate search results in extensible markup language (XML) fragment search, which is a search that produces only relevant fragments or portions of an XML document. The existing approaches generate a ranked list in descending order of each XML fragment's relevance to a search query; however, these approaches often extract irrelevant XML fragments and overlook more relevant fragments. To address these problems, our approach extracts relevant XML fragments by considering the size of the fragments and the relationships between the fragments. Next, we score the XML fragments to generate a refined ranked list. For scoring, we rank the XML fragments that are informative for user information needs as high in the list. In particular, each XML fragment is scored using the statistics of its descendant and ancestor XML fragments.Our experimental evaluations show that the proposed method outperforms BM25E, a conventional approach, which neither reconstructs XML fragments nor uses descendant and ancestor statistics.
