Resources and Processing of Linguistic and Extra - Linguistic Data from People with Various Forms of Cognitive / Psychiatric Impairments ( RaPID - 2016 )

Numerous studies have shown that language impairments, particularly semantic deficits, are evident in the narrative speech of people with Alzheimer’s disease from the earliest stages of the disease. Here, we present a novel technique for capturing those changes, by comparing distributed word representations constructed from healthy controls and Alzheimer’s patients. We investigate examples of words with different representations in the two spaces, and link the semantic and contextual differences to findings from the Alzheimer’s disease literature.
