We introduce the MFF algorithm for the task of verbal inflection analysis. This algorithm follows an heuristics that decide for the most frequent inflection feature bundle given the set of admissible feature bundles for a verb input form. This algorithm achieves a significantly better level of accuracy than the ones offered by current stochastic tagging technology commonly used for the same task.

Whether a word has an irregular inflection does not depend on its sound alone: compare lie-lay (recline) and lie-lied (prevaricate). Theories of morphology, particularly connectionist and symbolic models, disagree on which nonphonological factors are responsible. We test four possibilities: (1) Lexical effects, in which two lemmas differ in whether they specify an irregular form; (2) Semantic e...

Modern English approaches the ideal of an isolating language. Open-class items have comparatively few forms, so that many inflectional categories either remain unmarked, or are expressed periphrastically. The inflectional system is particularly simple, even by the standards of a West Germanic language. Regular paradigms contain at most four forms, and the inflectional exponents that distinguish...

How do we produce the past tenses of verbs? For the last 20 years this question has been the focal domain for conflicting theories of language, knowledge representation, and cognitive processing. On one side of the debate have been similarity-based or single-route approaches that propose that all past tenses are formed simply through phonological analogies to existing past tenses stored in memo...

The role of Broca's area in grammatical computation is unclear, because syntactic processing is often confounded with working memory, articulation, or semantic selection. Morphological processing potentially circumvents these problems. Using event-related functional magnetic resonance imaging (fMRI), we had 18 subjects silently inflect words or read them verbatim. Subtracting the activity patte...

An Inflection Point The tablet PC should provide the inflection point, the technological break that will provide the combination of portability and screen space required for real-life clinical use. Unlike a laptop, it can be held in one’s arm like the metal jacket of a patient chart, with data entered with a penlike device. This completely replicates the mode of data collection physicians have ...

The subject of this article is a description of Polish inflection in the form of a relational database. The description has been developed for a grammatical dictionary of Polish that aims at complete inflectional characterisation of all Polish lexemes. We show some complexities of the Polish inflectional system for various grammatical classes. Then we present a relatively compact relational mod...

We consider the Riemann problem for non-genuinely nonlinear conservation laws where the flux function admits two inflection points. This is a simplification of van der Waals fluid pressure, which can be seen as a function of the specific volume for a specific entropy at which the system lacks the non-genuine nonlinearity. Corresponding to each inflection point, A nonclassical Riemann solver can...

In the above examples, only nominal inflection shows opacity (i.e. it resists general phonological processes (2) or allows additional phonological contrasts (4)). Thus previous approaches commonly assume that nouns have a special status in phonology and propose constraints that are only effective for evaluation of nouns so as to explain opacity in nominal inflection. Such constraints include No...
