On the Complexity and Typology of Inflectional Morphological Systems
نویسنده
چکیده
We lay out a computational model for syntactic category acquisition which combines psychologically plausible concepts from minimally supervised part-of-speech tagging applications with simple distributional statistics. The model assumes a small set of seed words (Haghighi & Klein 2006), an approach with motivation in Pinker (1984)'s semantic bootstrapping hypothesis, and iteratively constructs a hierarchical clustering over a growing lexicon. Clustering is performed on the basis of word-adjacent syntactic frames alone (Mintz 2003) which has been shown to yield qualitatively coherent POS clusters (Reddington 1998), with no reference to morphological features. A prototype-driven labelling process based on tree-distance yields results comparable to computationally complex unsupervised algorithms while maintaining its cognitive underpinnings.

Dimensions of Morphological Complexity
e question of what aspects of a language’s word structure patterns contribute to its overall complexity has a long tradition. With roots in the notions of linguistic typology associated with traditional grammar, Sapir (; see also Anderson : §.) organizes these matters along three dimensions. One of these concerns the range of concepts represented by morphological markers, and refers ...
متن کاملLearning pressures reduce morphological complexity: Linking corpus, computational and experimental evidence
The morphological complexity of languages differs widely and changes over time. Pathways of change are often driven by the interplay of multiple competing factors, and are hard to disentangle. We here focus on a paradigmatic scenario of language change: the reduction of morphological complexity from Latin towards the Romance languages. To establish a causal explanation for this phenomenon, we e...
متن کاملA Study of Inflectional Categories of Noun in Sistani Dialect
The present article aims to provide a synchronic study of the inflectional or morpho-syntactic categories of noun in Sistani dialect. These categories comprise person, number, gender or noun class, definiteness, case, and possession. Linguistic data was collected via recording free speech, and interviewing with 30 (15 females, 15 males) illiterate Sistani language consultants of age 40–102 year...
متن کاملNeurocognitive mechanisms for processing inflectional and derivational complexity in English
In the current paper we discuss the mechanisms that underlie the processing of inflectional and derivational complexity in English. We address this issue from a neurocognitive perspective and present evidence from a new fMRI study that the two types of morphological complexity engage the language processing network in different ways. The processing of inflectional complexity selectively activat...
متن کاملConnections, Communication and Collaboration in Healthcare’s Complex Adaptive Systems; Comment on “Using Complexity and Network Concepts to Inform Healthcare Knowledge Translation”
A more sophisticated understanding of the unpredictable, disorderly and unstable aspects of healthcare organisations is developing in the knowledge translation (KT) literature. In an article published in this journal, Kitson et al introduced a new model for KT in healthcare based on complexity theory. The Knowledge Translation Complexity Network Model (KTCNM) provides a fresh perspective by mak...
