摘要:

词汇语义变化检测,即,识别随时间改变意义的单词的任务是一个非常活跃的研究领域,在NLP、词典学和语言学中有应用。评价是目前词汇语义变化检测中最紧迫的问题,因为没有金标准可供社区使用,这阻碍了进展。我们提出了第一个共享任务的结果,该任务通过为研究人员提供评估框架和手动注释的英语,德语,拉丁语和瑞典语的高质量数据集来解决这一差距。33个小组提交了186个系统,根据两个子任务对这些系统进行了评价。

英文摘要:

Lexical Semantic Change detection, i.e., the task of identifying words that change meaning over time, is a very active research area, with applications in NLP, lexicography, and linguistics. Evaluation is currently the most pressing problem in Lexical Semantic Change detection, as no gold standards are available to the community, which hinders progress. We present the results of the first shared task that addresses this gap by providing researchers with an evaluation framework and manually annotated, high-quality datasets for English, German, Latin, and Swedish. 33 teams submitted 186 systems, which were evaluated on two subtasks.
