English(EN) A Shared IPTC Topic Space for Cross-Source Topic Modelling

新框架使用共享分类法实现跨源主题比较

研究人员开发了一个新颖的框架来解决跨不同媒体来源比较主题关注度的问题。该框架通过使用 IPTC 媒体主题分类法对特定语料库的主题模型进行对齐,从而创建了一个单一的、共享的主题空间。该方法在《纽约时报》语料库上进行了测试,与零样本基准相比,其映射覆盖率更高,并且随着分配阈值的收紧,覆盖率逐渐下降。 AI

影响 提供了一种标准化的方法来比较不同数据集中的主题趋势,有可能改进媒体分析和信息检索。

    跨源主题建模的共享 IPTC 主题空间

    Comparing topic attention across different media is hindered by a fundamental modelling problem: topic models fitted separately to each corpus produce corpus-specific topic spaces that cannot be aligned directly. This paper presents a reproducible framework that places corpora in…
