自动确定和分配共享的和有意义的文本标签到从电子商务网页中提取的数据是一个具有挑战性的问题。电子商务网页可以显示数据记录的列表，每个数据记录可以包含数据项(例如产品名称和价格)和描述其中一些数据项的显式标签的组合。提取技术的最新进展使得从网页中精确地提取单独的数据项和标签变得容易得多，然而，存在两个未决问题：1.将显式标签分配给数据项，以及2.确定剩余数据项的标签。此外，词汇表的可用性和覆盖面的改善，特别是在电子商务网站的情况下，意味着我们现在可以访问一个相关的、有意义的和共享的标签库，这些标签可以分配给提取的数据项。然而，需要一种技术，该技术将一组提取的数据项作为输入，并自动为它们分配来自共享词汇表的最相关和最有意义的标签。我们注意到，信息提取(IE)社区已经开发了大量的技术，这些技术可以解决与我们自己类似的问题。在这篇正在进行中的论文中，我们打算从理论和实验上评估不同的IE技术，以确定哪种技术最适合解决这个问题。
Automatically determining and assigning shared and meaningful text labels to data extracted from an e-Commerce web page is a challenging problem. An e-Commerce web page can display a list of data records, each of which can contain a combination of data items (e.g. product name and price) and explicit labels, which describe some of these data items. Recent advances in extraction techniques have made it much easier to precisely extract individual data items and labels from a web page, however, there are two open problems: 1. assigning an explicit label to a data item, and 2. determining labels for the remaining data items. Furthermore, improvements in the availability and coverage of vocabularies, especially in the context of e-Commerce web sites, means that we now have access to a bank of relevant, meaningful and shared labels which can be assigned to extracted data items. However, there is a need for a technique which will take as input a set of extracted data items and assign automatically to them the most relevant and meaningful labels from a shared vocabulary. We observe that the Information Extraction (IE) community has developed a great number of techniques which solve problems similar to our own. In this work-in-progress paper we propose our intention to theoretically and experimentally evaluate different IE techniques to ascertain which is most suitable to solve this problem.
