AI总结:
针对嘈杂多语言社交媒体数据的地理实体链接问题,提出利用已标注位置名称的平均嵌入表示现实位置,并通过可解释置信度分数实现选择性预测,有效提升了全球多语言数据集上的链接效果。
摘要:
地理实体链接(geo-entity linking)是将位置提及链接到现实世界地理位置的任务。本文探讨了针对嘈杂、多语言社交媒体数据进行地理实体链接的挑战性任务。目前可用的开源多语言地理实体链接工具很少,且现有工具通常是基于规则的,在社交媒体环境中容易失效,或是基于 LLM 的,对于大规模数据集来说成本过高。我们提出了一种方法,将现实世界位置表示为来自已标注用户输入位置名称的平均嵌入,并允许通过可解释的置信度分数进行选择性预测。我们表明,我们的方法在全局和多语言社交媒体数据集上改进了地理实体链接,并讨论了在不同地理粒度下进行评估的进展与问题。
英文摘要:
Geo-entity linking is the task of linking a location mention to the real-world geographic location. In this paper we explore the challenging task of geo-entity linking for noisy, multilingual social media data. There are few open-source multilingual geo-entity linking tools available and existing ones are often rule-based, which break easily in social media settings, or LLM-based, which are too expensive for large-scale datasets. We present a method which represents real-world locations as averaged embeddings from labeled user-input location names and allows for selective prediction via an interpretable confidence score. We show that our approach improves geo-entity linking on a global and multilingual social media dataset, and discuss progress and problems with evaluating at different geographic granularities.
