While HTML is mainly designed for the visual rendering of Web documents, XML is widely accepted as a standard format to process and manage information. In particular, it can embed the information of logical structures. However, in order to utilize XML, the logical structures of HTML tables should first be extracted and transformed into XML representations. This paper presents an efficient method for the process, which consists of two phases: area segmentation and structure analysis. The area segmentation cleans up tables and segments them into attribute and value areas by checking visual and semantic coherency. The hierarchical structure between attribute and value areas is then analyzed and transformed into an XML representation using a proposed table model. Experimental results with 1180 HTML tables show that the proposed method performs better than conventional methods, resulting in an average accuracy of 86.7%. 相似文献

互联网上有大量信息采用HTML表格表示,由于HTML不描述数据的内容,机器不能理解和查询。论文利用HTML表格属性,在表格中插入冗余单元,使HTML表格规范化;对没有标志表头的HTML表格,采用格式化的信息的量化值识别网上表格的表头。在此基础上,提出了通过获取表格属性与值对应的语义层次,自动转换HTML表格数据为XML文挡的新方法。 相似文献

The article is concerned with time and the deluge of data that we can expect to collect and view. We examine this from the perspective of a subproblem, a database management system that records a person's life in its entirety - referred to here as DBMS[me] and E-me (that is, a database of me or an electronic model of me). Challenges for the DBMS[me] are to augment human memory by recording all data about an individual, to organize such data into models, and to develop security and privacy languages to control access to such models. 相似文献

In der Vergangenheit sind Web-Browser immer wieder h?chst negativ aufgefallen, wenn es um das Thema Sicherheit ging. Ein Gro?teil
dieser Missst?nde wurde im Laufe der vergangenen Jahre erkannt und nachgebessert. Nun steht HTML5, die n?chste Stufe der Browser-Evolution,
vor unserer Haustür. Gepr?gt durch die schlechten Erfahrungen der bisherigen Entwicklung begegnet man den neu eingeführten
Browser-Features vielerorts mit Mistrauen. Der vorliegende Beitrag stellt die Sicherheitseigenschaften von drei prominenten
HTML5-JavaScript APIs vor. 相似文献

有效地检索HTML文档 总被引:22,自引:1,他引:21
WWW上的资源大多以HTML格式的文档存储,同普通文档不同,THML文档的标签特性使得它具有一定的结构我们采取了一种检索,它扩展了传统的传统检索,利用HTML文档结构提高了在WWW环境下的检索和率。本文介绍了HTML的结构以及传统的向量空间信息检索提出了运用聚族方法为标符合分组;最后详细讨论了如何利用文棣结构扩展加权架,使得检索词能更贴切地描述文档,以提高检索的准确性。 相似文献
