Manuel Rafael Ciosici

During his studies, Manuel researched word representations and their role in Natural Language Processing. Word representation methods take in large corpora of human language text and compute ways to represent words in such a way that makes words understandable by computer algorithms. Manuel studied a kind of word representations based on word clusters and showed that they are highly effective at learning to represent syntactic information. With word representations based on vectors of floating point values, he proposed a method for determining the meaning of abbreviations based on their use in sentences.

The research contributes to understanding of word representations, when and how they should be used by computers to solve various language problems like word sense ambiguity.

The PhD degree was completed at the Computer Science Department, Science and Technology, Aarhus University.
