We present a morphological analyzer for Spanish called SMM. SMM is implemented in the grammar development framework Malaga, which is based on the formalism of Left-Associative Grammar. We briefly present the Malaga framework, describe the implementation decisions for some interesting morphological phenomena of Spanish, and report on the evaluation results from the analysis of corpora. SMM was originally only designed for analyzing word forms; in this article we outline two approaches for using SMM and the facilities provided by Malaga to also generate verbal paradigms. SMM can also be embedded into applications by making use of the Malagaprogramming interface; we briefly discuss some application scenarios.
Language-aware text editing
(2008)
While software developers have various power tools at their disposal that make the writing of computer programs more efficient, authors of texts do not have the support of such power tools. Text processors still operate on the level of characters and strings rather than on the level of word forms and grammatical constructions. This forces authors to constantly switch between low-level, character oriented, editing operations and high-level, conceptual, verbalisation processes. We suggest the development of language-aware text editing tools that simplify certain frequent, yet complex editing operations by defining them on the level of linguistic units. Pluralizing an entire noun phrase plus the verb forms governed by it would be an ambitious example, swapping the elements of a conjunctive construction a more modest one. We describe a pilot implementation for German where these operations are seamlessly integrated with the standard functions of an existing open-source editor. The operations can be invoked on demand and do not intrude on the authoring process. Changes can be performed locally or globally, thus simplifying the writing process considerably, and making the resulting texts more consistent.
In this paper the authors briefly outline editing functions which use methods from computational linguistics and take the structures of natural languages into consideration. Such functions could reduce errors and better support writers in realizing their communicative goals. However, linguistic methods have limits, and there are various aspects software developers have to take into account to avoid creating a solution looking for a problem: Language-aware functions could be powerful tools for writers, but writers must not be forced to adapt to their tools.
In this paper we present an evaluation of rule-based morphological components for German for use in an interactive editing environment. The criteria for the evaluation are deduced from the intended use of these components, namely availability, performance, programming interfaces, and analysis quality. We evaluated systems developed and maintained since decades as well as new systems. However, we note serious general shortcomings when looking closer at recent implementations and come to the conclusion that the oldest system is the only one that satisfies our requirements.
