我们提出了一个分类分类法在Web上的HTML表的大型爬行,主要集中在那些表,表达结构化的知识。该分类法将表分为两个顶级类:a)用于布局目的的类,包括导航和格式化;以及B)包含关系知识的类,包括列表、属性/值、矩阵、枚举和表单。然后,我们提出了一个分类算法,自动检测我们的分类法,即布局表和属性/值表的类的子集。我们报告我们的系统在Web上手动注释的HTML表的大样本的性能。
We propose a classification taxonomy over a large crawl of HTML tables on the Web, focusing primarily on those tables that express structured knowledge. The taxonomy separates tables into two top-level classes: a) those used for layout purposes, including navigational and formatting; and b) those containing relational knowledge, including listings, attribute/value, matrix, enumeration, and form. We then propose a classification algorithm for automatically detecting a subset of the classes in our taxonomy, namely layout tables and attribute/value tables. We report on the performance of our system over a large sample of manually annotated HTML tables on the Web.
