• Sommario/riassunto: One of the hardest problems in science is the symbol grounding problem, a question that has intrigued philosophers and linguists for more than a century. With the rise of artificial intelligence, the question has become very actual, especially within the field of robotics. The problem is that an agent, be it a robot or a human, perceives the world in analogue signals. Yet humans have the ability to categorise the world in symbols that they, for instance, may use for language. This book presents a series of experiments in which two robots try to solve the symbol grounding problem. The experiments are based on the language game paradigm, and involve real mobile robots that are able to develop a grounded lexicon about the objects that they can detect in their world. Crucially, neither the lexicon nor the ontology of the robots has been preprogrammed, so the experiments demonstrate how a population of embodied language users can develop their own vocabularies from scratch.

• Sommario/riassunto: Urban flooding is a significant challenge which today increasingly confronts the residents of the expanding cities and towns of developing countries, as well as policymakers and national, regional and local government officials. The Global Handbook presents the state-of-the art in urban flood risk management in a thorough and user-friendly way. It serves as a primer in integrated urban flood risk management for technical specialists, decision-makers and other concerned stakeholders in the private and community sectors. It covers ; the causes, probability and impacts of floods; the measures that
