Automatic Style Categorisation of Corpora in the Greek Language

In this article, a system is proposed for the automatic style categorisation of text corpora in the Greek language. This categorisation is based to a large extent on the type of language used in the text, for example whether the language used is representative of formal Greek or not. To arrive to this categorisation, the highly inflectional nature of the Greek language is exploited. For each text, a vector of both structural and morphological characteristics is assembled. Categorisation is achieved by comparing this vector to given archetypes using a statistical-based method. Experimental results reported in this article indicate an accuracy exceeding 98% in the categorisation of a corpus of texts spanning different registers.
