摘要

在本文中，我们探索了使用自然语言表达式在Web上执行地理搜索，而不诉诸于地理编码数据。这些表达式表示主题相对于地标的位置——这是嵌入在Web文档的非结构化文本中的有价值的地理上下文来源。我们的方法带来了新颖的查询扩展技术，几乎可以被任何基于关键字的搜索引擎探索。

Geographic web search based on positioning expressions

In this paper, we explore the use of natural language expressions to perform geographic searches on the Web, without resorting to geocoded data. Such expressions denote the positioning of a subject with respect to a landmark --- a valuable source of geographical context embedded in the unstructured text of Web documents. Our approach leads to novel query expansion techniques that can be explored by virtually any keyword--based search engine.
