Flat but not shallow. Towards flatter representations in deep semantic parsing for precise and feasible inferencing
Simulating human language understanding on the computer is a great challenge. A way to approach it is to represent natural language meanings in logic, and to use logical provers to determine what does and does not follow from a text. What logic is best to use and how natural language meanings are best…

Computational tools reveal secrets of 17th-century sealed letter
In a world first, an international team of researchers has read an unopened letter from Renaissance Europe – without breaking its seal or damaging it in any way. Nadine Akkerman, Reader in early modern English literature at Leiden University, is co-author of the article that appeared on 2 March in Nature…
