PhotoStand允许使用地图查询界面检索与新闻文章相关联的新闻照片，这些照片又与它们提到的主要位置相关联，这些主要位置是由于监测10,000多个RSS新闻提要的输出而收集的，在发布后几分钟内即可获得，并存储在PostgreSQL数据库中。根据新闻照片与与它们被显示的位置相关联的新闻文章簇的相关性来对新闻照片进行排序。这项工作与这一领域的传统工作不同，因为关联的位置和主题(由于包含新闻照片的文章与之相关联的集群)是自动生成的，而不需要任何人工干预，例如标记，并且照片是通过位置而不是像许多现有系统的情况那样仅通过关键字来检索的。此外，集群还提供了用于检测近似重复的新闻照片的过滤步骤。
PhotoStand enables the use of a map query interface to retrieve news photos associated with news articles that are in turn associated with the principal locations that they mention collected as a result of monitoring the output of over 10,000 RSS news feeds, made available within minutes of publication, and stored in a PostgreSQL database. The news photos are ranked according to their relevance to the clusters of news articles associated with locations at which they are displayed. This work differs from traditional work in this field as the associated locations and topics (by virtue of the cluster with which the articles containing the news photos are associated) are generated automatically without any human intervention such as tagging, and that photos are retrieved by location instead of just by keyword as is the case for many existing systems. In addition, the clusters provide a filtering step for detecting near-duplicate news photos.
