Abstract

Toponyms in texts and search queries are often used figuratively and do not directly refer to the locations they reference in their literal sense. Different usage kinds and stylistic devices characterize toponym usages in texts. It is thus crucial for a Geographic Information Retrieval (GIR) system to precisely distinguish these different toponym usages at indexing and at query time in order to best address a given information need and the geospatial footprint of a document. For that purpose, we analyze which of the classic stylistic devices such as allegories, metaphors, or metonymies are used together with toponyms. We use these categories as a foundation for a systematic approach towards the characterization of toponym usages in texts which we believe is necessary to further boost retrieval effectiveness of future GIR systems. A prototype implements this characterization exemplary for texts written in German. We evaluate the effectiveness of our approach against a reference corpus to show the general feasibility. Our approach provides a basis for a wide range of more sophisticated applications such as for example text genre detection.

文本中地名用法的表征

文本和搜索查询中的地名通常用作比喻，并不直接指它们在字面意义上所指的位置。不同的用法类型和文体手段决定了语篇中地名的用法。因此，地理信息检索(GIR)系统在索引和查询时精确区分这些不同的地名用法是至关重要的，以便最好地处理给定的信息需求和文档的地理空间足迹。为此，我们分析了哪些经典的文体手段，如寓言、隐喻或转喻与地名一起使用。我们使用这些分类作为对文本中地名用法的系统表征方法的基础，我们认为这对于进一步提高未来GIR系统的检索效率是必要的。一个原型实现了这种特征，作为德语文本的范例。我们针对参考语料库评估我们的方法的有效性，以显示总体可行性。我们的方法为许多更复杂的应用提供了基础，例如文本类型检测。
