The announcement of the discovery of a Higgs boson-like particle at CERN will be remembered as one of the milestones of the scientific endeavor of the 21(st) century. In this paper we present a study of information spreading processes on Twitter before, during and after the announcement of the discovery of a new particle with the features of the elusive… (More)
Human mobility and social structure are at the basis of disease spreading. Disease containment strategies are usually devised from coarse-grained assumptions about human mobility. Cellular networks data, however, provides finer-grained information, not only about how people move, but also about how they communicate. In this paper we analyze the behavior of… (More)
In the 1980's, the analysis of presupposition projection contributed to a 'dynamic turn' in semantics: the classical notion of meanings as truth conditions was replaced with a dynamic notion of meanings as Context Change Potentials (Heim 1983). We explore an alternative in which presupposition projection follows from the combination of a fully classical… (More)
We will study the basic properties of human linguistic abilities by looking first at much simpler languages, 'language fragments', with particular attention to our ability to learn the semantic values of expressions and the role this could have in 'bootstrapping' the language learner.
