摘要:

长期Web档案包括在较长时间段内收集的Web文档,大小可以轻松达到数百TB。语义注释(如命名实体)可以促进对Web存档数据的智能访问。然而,以这种规模对整个档案内容进行注释往往是不可行的。访问Web存档中文档的最有效方法是通过它们的URL,URL通常存储在专用的索引文件中,存档的Web文档的URL可以包含语义信息,并且可以提供一种有效的方法来获得存档文档的初始语义注释。在本文中,我们分析了语义分析技术,如命名实体提取的URL在Web存档的适用性。我们评估了从Popular German Web数据集中的URL中提取命名实体的精度,并分析了这些技术适用于2000年至2012年期间1,444个流行域的存档URL的比例。我们的研究结果表明,命名实体识别可以成功地应用于大量的URL在我们的Web存档,并提供了一个很好的起点,有效地注释大规模的Web文档集合。

英文摘要:

Long-term Web archives comprise Web documents gathered over longer time periods and can easily reach hundreds of terabytes in size. Semantic annotations such as named entities can facilitate intelligent access to the Web archive data. However, the annotation of the entire archive content on this scale is often infeasible. The most efficient way to access the documents within Web archives is provided through their URLs, which are typically stored in dedicated index files.The URLs of the archived Web documents can contain semantic information and can offer an efficient way to obtain initial semantic annotations for the archived documents. In this paper, we analyse the applicability of semantic analysis techniques such as named entity extraction to the URLs in a Web archive. We evaluate the precision of the named entity extraction from the URLs in the Popular German Web dataset and analyse the proportion of the archived URLs from 1,444 popular domains in the time interval from 2000 to 2012 to which these techniques are applicable. Our results demonstrate that named entity recognition can be successfully applied to a large number of URLs in our Web archive and provide a good starting point to efficiently annotate large scale collections of Web documents.
