This article reports on the current state of our efforts to shed light on the origin and evolution of linguistic diversity using synthetic modeling and artificial life techniques. We construct a simple abstract model of a communication system that has been designed with regard to referential signaling in nonhuman animals. We analyze the evolutionary dynamics of vocabulary sharing based on these...

Lexical and morphological knowledge of school-aged children are correlated with each other, and are often difficult to distinguish. One reason for this might be that many tasks currently used to assess morphological knowledge require children to inflect or derive real words in the language, thus recruiting their vocabulary knowledge. The current study investigated the possible separability of l...

Literature search is a process in which external developers provide alternative representations for efficient data mining of biomedical literature such as ranking search results, displaying summarized knowledge of semantics and clustering results into topics. In clustering search results, prominent vocabularies, such as GO (Gene Ontology), MeSH(Medical Subject Headings) and frequent terms extra...

DEFINITION. A de termin i s t i c l inear bounded a u t o m a t o n (DLBA) is a sixtuple (Q, q0, V, # 1 , # 2 , J ) where: Q is a finite set of states q o , q l .... ; q o E Q is the initial state; V is a finite vocabulary; # 1 , #2 6 V are left and right endmarkers, respectively; and J is a finite set of instructions. T h e automaton consists of two pushdown lists, called L and R, and a finite...

1Q ABSTRACT It has long been known that one of the key factors in determining the accuracy of isolated word recognition systems is the size and/or complexity of the vocabulary. Although most practical isolated word recognizers use small vocabularies (on the order of 10 to 50 words), there are many applications which require medium to large size vocabularies (e.g. airlines reservation and inform...

We introduce parameterized rewrite systems for describing infinite families of finite string rewrite systems depending upon non-negative integer parameters, as well as ways to reason uniformly over these families. Unlike previous work, the vocabulary on which a rewrite system in the family is built depends itself on the integer parameters. Rewriting makes use of a toolkit for parameterized word...

We analyse the expressiveness of Brewka and Woltran’s abstract dialectical frameworks for two-valued semantics. By expressiveness we mean the ability to encode a desired set of two-valued interpretations over a given propositional vocabulary A using only atoms from A. We also compare ADFs’ expressiveness with that of (the two-valued semantics of) abstract argumentation frameworks, normal logic ...
