We describe a morphological analyzer for the Swahili language, written in an extension of XFST/LEXC intended for the easy declaration of morphophonological patterns and importation of lexical resources. Our analyzer was supplemented extensively with data from the Kamusi Project (kamusi.org), a user-contributed multilingual dictionary. Making use of this resource allowed us to achieve wide lexic...

These are notes from introductory survey lectures given at the Institute for Studies in Theoretical Physics and Mathematics (IPM), Teheran, in 2008 and 2010. We present the definition and the fundamental properties of Fomin-Zelevinsky’s cluster algebras. Then, we introduce quiver representations and show how they can be used to construct cluster variables, which are the canonical generator...

Anomalies in intertemporal choice (e.g. hyperbolic discounting, subadditive discounting, a sign effect, a magnitude effect, and a delay-speedup asymmetry) have been investigated in neuroeconomics and behavioral neuroeconomics. In this study we propose a “tempospect” theory of intertemporal choice which can account for these anomalies in intertemporal choice. The key features of the present theo...

Abstract It is known that if $$f:{{\mathbb R}}^2\rightarrow {\mathbb R}$$ f : R 2 → a polynomial in each variable, then f polynomial. We present generalizations of this fact, when $${{\mathbb R}}^...

A new hybrid approach to the coreference resolution problem is presented. The CORUDIS system (COreference RUles with DIsambiguation Statistics) combines syntactico-semantic rules with statistics derived from an annotated corpus. First, the rules and corpus annotations are described and exemplified. Then, the coreference resolution algorithm and the involved statistics are explained. Finally, th...

In this paper, we propose a unified framework for the syntactico-semantic learning of natural languages. This framework integrates recent results on grammatical inference with positive structural examples and an algebraic characterization of the Principle of Compositionality, introduced by linguists and logicians. The purpose is to give account of how children learn to understand their native l...

We are developing a large-scale model of language comprehension in ACT-R 6 for use in the creation of a synthetic teammate that can function as the Air Vehicle Operator (AVO) in a three-person simulation of an Unmanned Aerial Vehicle (UAV) team performing a reconnaissance mission. The use of ACT-R 6 to implement the core components of this system reflects the strong cognitive modeling orientati...

ionist models typically work with sparse lexicons, with as only exception in generative grammar the work of Jackendoff (1975). Once the linguistic generalizations of the language have been deduced from the input, the input words are no longer needed to support the generalizations. If they are morphologically complex and completely regular in all respects, they can even be removed from the lexic...
