Missing Elsewhere: Domain Extension in Contextual Allomorphy

Feature-Based Allomorphy

Morphotactics and allomorphy are usually modeled in different components, leading to interface problems. To describe both uniformly, we define finite automata (FA) for allomorphy in the same feature description language used for morphotactics. Nonphonologically conditioned allomorphy is problematic in FA models but submits readily to treatment in a uniform formalism. 1 Background and Goals ALLO...

A Contextual-Logic Extension of TOSCANA

A kernel extension to handle missing data

An extension for univariate kernels that deals with missing values is proposed. These extended kernels are shown to be valid Mercer kernels and can adapt to many types of variables, such as categorical or continuous. The proposed kernels are tested against standard RBF kernels in a variety of benchmark problems showing different amounts of missing values and variable types. Our experimental res...

Weakly supervised learning of allomorphy

Most NLP resources that offer annotations at the word segment level provide morphological annotation that includes features indicating tense, aspect, modality, gender, case, and other inflectional information. Such information is rarely aligned to the relevant parts of the words—i.e. the allomorphs, as such annotation would be very costly. These unaligned weak labelings are commonly provided by...

Stress and Allomorphy in Woleaian Reduplication

Woleaian shares the progressive and denotative affixes seen in other Trukic and Ponapeic languages of Western Micronesia (Harrison 1973, Sohn 1975). The progressive is invariably a prefix, and like in other Trukic languages (such as Chuukese, Puluwat, and Ulithian) it is bimoraic, with the second mora realized by geminating the initial consonant of the stem (fati → faf-fati ‘being angular’, fil...
