The paper focuses on the field of automatic extraction of information from texts and text document categorisation including pre-processing of text documents, which can be found on the Internet. In the frame of the presented work, we have devoted our attention to the following issues related to text categorisation: increasing the precision of categorisation algorithm results with the aid of a bo...

If work in psychology has clearly brought to light the existence of “conceptual flexibility” in the categorisation of objects, which led to a re-questioning of the traditional conception of categorisation which considers rigid and discontinuous categories, it is not the case in linguistics and psycholinguistics. We propose, through a highlighting of the role of analogy in the categorisation of ...

We propose and study a new variant of the SVM — the SVM with uneven margins, tailored for document categorisation problems (i.e. problems where classes are highly unbalanced). Our experiments showed that the new algorithm significantly outperformed the SVM with respect to the document categorisation for small categories. Furthermore, we report the results of the SVM as well as our new algorithm...

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 te...

This paper presents the results of a pitch accent categorisation simulation which attempts to classify L*H and H*L accents using a psychologically motivated exemplar-theoretic model of categorisation. Pitch accents are represented in terms of six linguistically meaningful parameters describing their shape. No additional information is employed in the categorisation process. The results indicate...

The structural elements of the prosodic hierarchy and the ways in which phonological generalisations make reference to them are investigated. Assuming, as argued, that these elements constitute a universal set of primitives, the different types (categories) of such elements, especially the syllable, are examined more closely. Specifically, the traditional weight dichotomy of ‘heavy’ vs. ‘light’...
