Positional and cooccurrence restrictions on ejectives

Positional effects on the characterization of ejectives in Waima'a

This paper presents results from an ongoing investigation into stop consonants in Waima’a, focusing on the issue of tense v. lax ejectives. Sources tend to describe ejectives in a given language as either tense or lax; however ejectives in Waima'a, do not fit squarely into either category [4]. Here we compare ejectives in word-initial and word-medial contexts, to specifically address the role o...

Category Cooccurrence Restrictions and the Elimination of Metarules

This paper builds upon and extends certain ideas developed within the framework of Generalized Phrase Structure Grammar (GPSG). ill A new descriptive device, the Category Cooccurrence Restriction (CCR), is introduced in analogy to existing devices of GPSG in order to express constraints on the cooccurrence of categories within local trees (i.e. trees of depth one) which at present are stated wi...

Using Semantic Similarity To Acquire Cooccurrence Restrictions From Corpora

We describe a method for acquiring semantic cooccurrence restrictions for tuples of syntactically related words (e.g. verb-object pairs) from text corpora automatically. This method uses the notion of semantic similarity to assign a sense from a dictionary database (e.g. WordNet) to ambiguous words occurring in a syntactic dependency. Semantic similarity is also used to merge disambiguated word...

The Role of Contrast in Laryngeal Cooccurrence Restrictions

The central proposal in this paper is that laryngeal cooccurrence restrictions are restrictions on contrasts between forms in a language, not restrictions on isolated forms or structures. Combinations of laryngeal features are only marked with respect to what other combinations of laryngeal features they contrast with. The analysis hinges on the hypothesis that the two types of laryngeal contra...
