    • A search method uses pseudo-anchor text associated with search objects to improve search performance. The pseudo-anchor text may be extracted in combination with an identifier of the search objects (such as a pseudo-URL) from a digital corpus such as a collection of documents. Pseudo-anchor texts for each object are preferably extracted from candidate anchor blocks using a machine learning based approach. The pseudo-anchor texts are made available for searching and used to help rank the objects in a search result to improve search performance. The method may be used in vertical search of objects such as published articles, products and images that lack explicit URLs and anchor text information.
    • 搜索方法使用与搜索对象相关联的伪锚文本来改善搜索性能。 伪锚文本可以与来自诸如文档集合的数字语料库的搜索对象(诸如伪URL)的标识符组合提取。 优选地,使用基于机器学习的方法从候选锚块中提取每个对象的伪锚文本。 伪锚文本可用于搜索,并用于帮助对搜索结果中的对象进行排名以提高搜索性能。 该方法可以用于垂直搜索诸如已发表的文章,产品和缺乏明确的URL和锚文本信息的图像的对象。
