A finite-state approach to arabic broken noun morphology
In this paper, a finite-state computational approach to Arabic broken plural noun morphology is introduced. The paper considers the derivational aspect of the approach, and how generalizations about dependencies in the broken plural noun derivational system of Arabic are captured and handled computationally in this finite-state approach. The approach will be implemented using Xerox finite-state tool
Morphological Computation: Nothing but Physical Computation
The purpose of this paper is to argue against the claim that morphological computation is substantially different from other kinds of physical computation. I show that some (but not all) purported cases of morphological computation do not count as specifically computational, and that those that do are solely physical computational systems. These latter cases are not, however, specific enough: all computational systems, not only morphological ones, may (and sometimes should) be studied in various ways, including their energy efficiency, cost, reliability, and durability. Second, I critically analyze the notion of “offloading” computation to the morphology of an agent or robot, by showing that, literally, computation is sometimes not offloaded but simply avoided. Third, I point out that while the morphology of any agent is indicative of the environment that it is adapted to, or informative about that environment, it does not follow that every agent has access to its morphology as the model of its environment
Temiar Reduplication in One-Level Prosodic Morphology
Temiar reduplication is a difficult piece of prosodic morphology. This paper
presents the first computational analysis of Temiar reduplication, using the
novel finite-state approach of One-Level Prosodic Morphology originally
developed by Walther (1999b, 2000). After reviewing both the data and the basic
tenets of One-level Prosodic Morphology, the analysis is laid out in some
detail, using the notation of the FSA Utilities finite-state toolkit (van Noord
1997). One important discovery is that in this approach one can easily define a
regular expression operator which ambiguously scans a string in the left- or
rightward direction for a certain prosodic property. This yields an elegant
account of base-length-dependent triggering of reduplication as found in

Computer analysis of the Turkmen language morphology
This paper describes the implementation of a two-level morphological analyzer for the Turkmen Language. Like all Turkic languages, the Turkmen Language is an agglutinative language that has productive inflectional and derivational suffixes. In this work, we implemented a finite-state two-level morphological analyzer for Turkmen Language by using Xerox Finite State Tools
Common Infrastructure for Finite-State Based Methods and Linguistics Descriptions
Finite-state methods have been adopted widely in computational morphology and related linguistic applications. To enable efficient development of finite-state based linguistic descriptions, these methods should be a freely available resource for academic language research and the language technology industry. The following needs can be identified: (i) a registry that maps the existing approaches, implementations and descriptions, (ii) managing the incompatibilities of the existing tools, (iii) increasing synergy and complementary functionality of the tools, (iv) persistent availability of the tools used to manipulate the archived descriptions, (v) an archive for free finite-state based tools and linguistic descriptions. Addressing these challenges contributes to building a common research infrastructure for advanced language technology.Peer reviewe
