1. Knowledge based perceptual anchoring : grounding percepts to concepts in cognitive robots
Abstract : A successful articial cognitive agent needs to integrate its perception of the environment with reasoning and actuation. A key aspect of this integration is the perceptual-symbolic correspondence, which intends to give meaning to the concepts the agent refers to { known as Anchoring. However, perceptual representations alone (e.g. READ MORE

2. Studies in Semantic Modeling of Real-World Objects using Perceptual Anchoring
Abstract : Autonomous agents, situated in real-world scenarios, need to maintain consonance between the perceived world (through sensory capabilities) and their internal representation of the world in the form of symbolic knowledge. An approach for modeling such representations of objects is through the concept of perceptual anchoring, which, by definition, handles the problem of creating and maintaining, in time and space, the correspondence between symbols and sensor data that refer to the same physical object in the external world.

3. Teaching mobile robots to use spatial words
Abstract : The meaning of spatial words can only be evaluated by establishing a reference to the properties of the environment in which the word is used. For example, in order to evaluate what is to the left of something or how fast is fast in a given context, we need to evaluate properties such as the position of objects in the scene, their typical function and behaviour, the size of the scene and the perspective from which the scene is viewed.

4. Semantic change in interaction: Studies on the dynamics of lexical meaning
Abstract : This compilation thesis investigates how word meanings change. In particular, it's concerned semantic change at the levels of interaction and the speech community. To this end, the compiled studies employ methods from both formal and computational semantics. READ MORE
