The "Corpus Anchise 320" and the Analysis of Conversations between Healthcare Workers and People with Dementia

The aim of this research was to create the first Italian corpus of free conversations between healthcare workers and people with dementia, in order to investigate specific linguistic phenomena from a computational point of view. Most of the previous researches on speech disorders of people with dementia have been based on qualitative analysis, or on the study of a few dozen cases executed in laboratory conditions, and not in spontaneous speech (in particular for the Italian language). The creation of the Corpus Anchise 320 aims to investigate Dementia language by providing a broader number of dialogues collected in ecological conditions and obtained transcribing spontaneous speech. Moreover, quantitative linguistic analysis can show some peculiarities of this language.
