CLT seminar: Ildiko Pilan – Towards a meeting point between linguistic complexity and word senses

SEMINAR

The role of semantic aspects in the automatic assessment of linguistic complexity (readability) remains little explored in the literature, mostly due to the lack of reliable word-sense disambiguation (WSD) methods. This talk will give an overview of our research carried out in both the area of readability classification and WSD with the aim of working towards their future combination. In the first part, I will present a machine learning approach for classifying coursebook materials for teaching Swedish as a second language according to their linguistic complexity. Besides results for text-level analysis, I will also discuss performance at a finer-grained (sentence) level. The second half of the presentation will be dedicated to a first attempt at a knowledge-based WSD system using information from the SALDO lexicon. After the description of the method, some example sentences with both correctly and incorrectly disambiguated senses will follow. Finally, I will conclude with outlining the potentials of sense-based information for readability classification.
