The Use of Formal Language Models in the Typology of the Morphology of Amerindian Languages
نویسنده
چکیده
The aim of this work is to present some preliminary results of an investigation in course on the typology of the morphology of the native South American languages from the point of view of the formal language theory. With this object, we give two contrasting examples of descriptions of two Aboriginal languages finite verb forms morphology: Argentinean Quechua (quichua santiagueño) and Toba. The description of the morphology of the finite verb forms of Argentinean quechua, uses finite automata and finite transducers. In this case the construction is straightforward using two level morphology and then, describes in a very natural way the Argentinean Quechua morphology using a regular language. On the contrary, the Toba verbs morphology, with a system that simultaneously uses prefixes and suffixes, has not a natural description as regular language. Toba has a complex system of causative suffixes, whose successive applications determinate the use of prefixes belonging different person marking prefix sets. We adopt the solution of Creider et al. (1995) to naturally deal with this and other similar morphological processes which involve interactions between prefixes and suffixes and then we describe the toba morphology using linear context-free languages.1.

Modeling and Evaluation of Stochastic Discrete-Event Systems with RayLang Formalism
In recent years, formal methods have been used as an important tool for performance evaluation and verification of a wide range of systems. In the view points of engineers and practitioners, however, there are still some major difficulties in using formal methods. In this paper, we introduce a new formal modeling language to fill the gaps between object-oriented programming languages (OOPLs) us...

متن کاملIdentity and Representation through Language in Ghana: The Postcolonial Self and the Other
Research related to colonialism and post colonialism shows how the identities of indigenous people were constructed and how these identities are reconstructed in our contemporary world. The thrust of this paper is that colonialism brought a shift in the linguistic structure of Ghana with the introduction of the use of English among Ghanaians. The coexistence of both Ghanaian languages and Engli...
متن کاملThe Typology of EFL Teachers’ Codeswitching: A Validation Study
The use of L1 in language classroom has been traditionally repressed by applied linguists. However, in recent years, it is believed that switching to L1 can be considered a pedagogical instrument by teachers rather than a heterodox. Consequently, this two-phase study was an attempt to investigate the functions that are fulfilled by EFL teachers through their use of L1. In the first phase (i.e.,...
