- As a compact and efficient way to present relational information , tables are used frequently in web documents
而表格作为一种简洁有效的数据信息表达方式,在各种领域的web页中都用得十分广泛。 - The appearance of web information extraction provides a good solution of this problem , which could help people get the knowledge more quickly and more exactly . as a compact and efficient way to present relational information , tables are used frequently in web documents . according to the report , about 52 % of html documents include tables
作为一个表达关系信息的简洁而有效的途径,表格在web文本中被经常使用,根据研究发现,在52 %的html文档中,使用table标签,虽然其中一些表格是用来使页面布局变得美观,但大部分表格是用来存放数据信息。 - The structure recognization of web table can be processed by two phases . first we need to filter out those non - genuine tables which is uesd not for relational information display but for creating any type of multiple - column layout to facilitate easy viewing . according to lots of observations to tables in web pages , the features are identified which best capture the characteristics of the genuine table compared to a non - genuine one , and then get the heuristic rules . based on these rules , algorithms are designed and implemented to evaluate the performance , as measured by ie evaluation metrics - recall , precision and f - measure . the result show that the performance of our algorithms is not less effectively than others
首先从纷繁复杂的web页面中滤去那些用于控制页面结构而不是表达有效数据信息的“假表格” 。本文通过大量的观察,提取出识别真假表格的特征信息,形成启发式规则;在此基础上设计并实现一系列算法;最后通过传统的信息抽取指标? ?召回率、准确率和f指数来衡量识别结果。实验显示,本文的算法有较强的表格识别能力。
