Invited Speakers

Albert Gatt

Albert Gatt is a Senior Lecturer and Director at Institute of Linguistics and Language Technology, University of Malta. He is a member of the RiVaL (Research in Vision and Language) research group and affiliated with the Blockchain research group. His research mostly focusses on the generation of language by machines (a.k.a. Natural Language Generation) and the production of language by humans.

Title: Grounding Natural Language Inference: Classifying and Generating Entailments using Visual Information

Roberto Basili

Roberto Basili is a Professor at the Department of Computer Science of the University of Roma, Tor Vergata and member of the Artificial Intelligence group at Tor Vergata (ART) since 1991. His research is on Natural Language Processing, Machine Learning, knowledge representation and applications such as Information Retrieval and Semantic Web.

Title: Inside NLP systems: between representation learning and ethics.

Abstract: Ethics is a crucial problem for current AI research for the widespread adoption of intelligent systems and devices. Although ethics has been studied in AI under several perspectives, the role of natural language 
learning has not yet fully outlined. Rather than a linguistic perspective on ethics, that recently characterize a large set of studies on neural NLP, in the talk I will try to discuss role and perspectives in the use of linguistic information for the explanation of neural models, and how these latter are connected with ethically sustainable systems.
