We present a supervised machine learning system for word-level classification of all content words in a running text as being metaphorical or non-metaphorical. The system provides a substantial improvement upon a previously published baseline, using re-weighting of the training examples and using features derived from a concreteness database. We observe that while the first manipulation was ver...

On the “standard” view of conceptual metaphors (Lakoff and Johnson, 1980; Kövecses, 2002), metaphorical creativity arises from cognitive processes extending, elaboration, questioning, combining content in source domain Turner, 1989). I will propose that such cases constitute only a part creativity. An equally important common set is comprised by what call “context-induced” metaphors. discuss fi...

The convergence of an alternating direction implicit method for Maxwell’s equations on product domains is investigated. Unlike the classical Yee scheme and most other integrators proposed in the literature, this method is both unconditionally stable and computationally cheap. We prove second-order convergence of the time-discretization in the framework of operator semigroup theory. In contrast ...

We analyze the interaction of explicit and implicit contracts in a model with selfish and fair principals. Fair principals are willing to honor implicit agreements, whereas selfish principals are not. Principals are privately informed about their types. We investigate a separating equilibrium in which principals reveal their type through the contract offer to the agent. If this equilibrium is p...

This paper describes a system designed to perform text interpretation and reasoning using a spatial processor and a network of prototypical memories. These memories of basic embodied acts such as moving and grasping, are organized in a hierarchical structure based on the system’s own set of grounded feelings associated with each memory. The prototypes form metaphor schemas organized into a tall...
