We are happy to announce the first two titles in the series *Elements in Semantics,* published by Cambridge University Press, both by Kristina Liefke.

Given how fundamental ontology is to semantics, it is particularly apposite that the first titles in the series address this topic. CUP makes these works freely available for download until January 4 and January 8, respectively:

Kristina Liefke *Natural Language Ontology and Semantic Theory* https://tinyurl.com/3kv5wcdj

Kristina Liefke *Reduction and Unification in Natural Language Ontology* https://tinyurl.com/bdk5ufat

Forthcoming titles in the series to appear shortly include: Lasha Abzianidze, Lisa Bylinina, and Denis Paperno *Deep Learning and Semantics, *

Stergios Chatzikyriakidis, Robin Cooper, Eleni Gregoromichelaki, and Peter Sutton *Types and the structure of meaning: Issues in compositional and lexical semantics, *

Katherine Davidson *s*

*About Elements in Semantics* Interest in semantics has exploded in a number of fields in recent years. Yet there are still many unresolved issues about basic issues in the field, as well as new questions that have arisen as a result of interdisciplinary engagement. What are word meanings, and where do they come from? How can we explain the learnability of language and its structured nature? What are the computational properties of language, and how does the brain implement these? How does individual cognition relate to the social aspect of meaning? These, and many more, have been raised or sharpened as a result of engagement with game theory, robotics, and deep learning, to name a few. Given the importance of meaning in human cognition and society at large, results in semantics bear on issues as diverse as legal decision-making and the use of spoken dialogue systems to operate a robot on Mars.

The innovative edge of Elements in Semantics consists in three aspects in particular. First, we provide a platform that emphasizes the interdisciplinary nature of current work in semantics. Second, Elements will offer an integrated account of classical topics in semantics (e.g., negation, anaphora, conditionals) from a broader range of disciplines than traditional surveys. Third, Elements offers authors the ability to convey their research to audiences in innovative ways, using in-line audio and video as well as in-line simulations and data analysis via runnable code snippets in a variety of programming languages.
