摘要:

虽然社会事件经常影响世界各地的人们,但很大一部分事件的焦点主要是影响特定语言社区的地方焦点。例子包括全国选举、不同国家的冠状病毒大流行的发展,以及当地的电影节,如法国的塞萨尔奖和俄罗斯的莫斯科国际电影节。然而,现有的实体推荐方法没有充分解决推荐的语言环境。本文介绍了一种新的任务,特定语言的事件推荐,其目的是推荐相关的用户查询在特定语言的上下文事件。此任务可以支持基本的信息检索活动,包括Web导航和探索性搜索,考虑到用户信息需求的语言环境。我们提出了激光,一种新的方法对特定语言的事件推荐。Laser在学习排序模型中融合了实体和事件的语言特定潜在表示(嵌入)以及时空事件特征。这个模型是在公开的维基百科点击流数据上训练的。我们的用户研究结果表明,在MAP@5中,关于推荐事件的特定语言相关性,Laser的性能超过最先进的推荐基线高达33个百分点。

英文摘要:

While societal events often impact people worldwide, a significant fraction of events has a local focus that primarily affects specific language communities. Examples include national elections, the development of the Coronavirus pandemic in different countries, and local film festivals such as the César Awards in France and the Moscow International Film Festival in Russia. However, existing entity recommendation approaches do not sufficiently address the language context of recommendation. This article introduces the novel task of language-specific event recommendation, which aims to recommend events relevant to the user query in the language-specific context. This task can support essential information retrieval activities, including web navigation and exploratory search, considering the language context of user information needs. We propose LaSER, a novel approach toward language-specific event recommendation. LaSER blends the language-specific latent representations (embeddings) of entities and events and spatio-temporal event features in a learning to rank model. This model is trained on publicly available Wikipedia Clickstream data. The results of our user study demonstrate that LaSER outperforms state-of-the-art recommendation baselines by up to 33 percentage points in MAP@5 concerning the language-specific relevance of recommended events.
