Humour remains one of the most difficult aspects of intercultural communication. Understanding humor often involves understanding implicit cultural references and/or double meanings, especially in the case of wordplay, which raises not only the question of its (un)translatability, but also how to detect and classify instances of this complex phenomenon. The goal of the JOKER track is to bring together linguists, translators, and computer scientists to create reusable test collections for benchmarking and to explore new evaluation metrics in order to foster work on automatic methods for wordplay interpretation, generation, and translation.

A new book co-edited with Nina Tahmasebi, Lars Borin, Yang Xu and Simon Hengchen appeared on the topic of computational approaches to semantic change [1]. Semantic change — how the meanings of words change over time — has preoccupied scholars for a long time. Compared to changes in sound and grammar, semantic change is the least understood. Ever since, the study of semantic change has progressed steadily, accumulating a vast store of knowledge for over a century, encompassing many languages and language families. Big-data empirical quantitative investigations are now coming to the forefront, enabled by enormous advances in storage capability and processing power. This volume offers a survey of this exciting new direction in the computational study of semantic change, addressing both more theoretical problems — e.g., discovery of “laws of semantic change” — and practical applications, such as information retrieval in longitudinal text archives.
