This chapter presents an analysis of the prosodic and intonational structure of Catalan within the Autosegmental-Metrical (AM) framework (Pierrehumbert 1980, Pierrehumbert and Beckman 1988, Ladd 1996, Gussenhoven 2004, Jun 2005, and Beckman et al. 2005, among others). Based on this analysis, we have developed the Cat_ToBI system of prosodic annotation of Catalan corpora (Prieto, Aguilar, Mascar...

We describe the system submitted to IBEREVAL-2017 for stance and gender detection in tweets on Catalan Independence [1]. We developed a supervised system using Support Vector Machines with radial basis function kernel to identify the stance and gender of the tweeter using various character level and word level features. Our system achieves a macro-average of F-score(FAVOR) and F-score(AGAINST) ...

We first observe that the relations of the canonical generating isometries of the Cuntz algebra ON are naturally related to the N-colored Catalan numbers. For a directed graph G, we generalize the Catalan numbers by using the canonical generating partial isometries of the Cuntz-Krieger algebra O AG for the transition matrix A of G. The generalized Catalan numbers cGn , n = 0, 1, 2, . . . enumer...

Preliminary Sermon: Humans will be Humans; The Medium is the Message The famous Catalan numbers (see [Sl1]), count zillions of combinatorial families (see [St]) and many humans have fun trying to find ‘nice’ bijections between family A and family B. While this may be fun for a while, sooner or later this game gets old, especially since the real reason Catalan numbers are so ubiquitous is their ...

We show that the generating functions of the generalized Catalan numbers can be identified with the moment generating functions of probability density functions related to the Brownian motion stochastic process. Specifically, the probability density functions are exponential mixtures of inverse Gaussian (EMIG) probability density functions, which arise as the first passage time distributions to...

Riordan matrix methods and manipulation of various generating functions are used to find curious relations among the Catalan, central binomial, and RNA generating functions. In addition, the Wilf-Zeilberger method is used to find identities where the gamma function and Catalan numbers are expressed in terms of the Gauss hypergeometric function. As a consequence of the identities, new recurrence...

Every character on a graded connected Hopf algebra decomposes uniquely as a product of an even character and an odd character [2]. We obtain explicit formulas for the even and odd parts of the universal character on the Hopf algebra of quasi-symmetric functions. They can be described in terms of Legendre’s beta function evaluated at halfintegers, or in terms of bivariate Catalan numbers: C(m, n...

q-analogs of the Catalan numbers c', = (I/(n + I))($) are studied from the viewpoint of Lagrange inversion. The first, due to Carhtz, corresponds to the Andrews-Gessel-Garsia q-Lagrange inversion theory, satisfies a nice recurrence relation and counts inversions of Catalan words. The second, tracing back to Mac Mahon, arise from Krattenthaler's and Gessel and Stanton's q-Lagrange inversion form...

In recent years, and for the first time in Spanish economic history, outward direct investment flows outweigh inward flows. Catalan manufacturing not only mirrors this pattern, but also represents a high proportion of all Spanish manufacturing outward direct investment. In this paper, we analyse the factors that determine outward direct investment by Catalan manufacturing firms. We apply Dunnin...
