Introduction to the workshop

Nov 22, 11.10 – 12.10

Invited Speaker

Malvina Nissim 

Title: Who can do author profiling?

Abstract: 

State-of-the-art performance on author profiling (e.g., gender and age) for English in social media is around 80%, or even higher. I will present systems that yield those results, but I will also question the reliability of such figures.
Specifically, I will show that the same reasons why these models work are also the cause of serious performance drops when we change, even moderately, domain or topic. If we create conditions to bypass such powerful but at the same time limiting clues, we might be able to identify features that are indeed more relevant for profiling, and we will build more portable systems.
I will describe experiments in this direction, exploring whether portability can be stretched even into a cross-language setting. I will also compare these flexible models to human performance in quite an interesting way!

Invited Speaker

Oliviero Stock has been at IRST (now called FBK-irst) since 1988 and has been its director from 1997 to 2001. His activity is in artificial intelligence, natural language processing, intelligent user interfaces, cognitive technologies, computational creativity. He is the author of over two hundred and sixty peer-reviewed papers and author or editor of twelve volumes, and has been a member of the editorial board of a dozen scientific journals. He has been the second President of AI*IA, Chairman of the European Coordinating Committee for Artificial Intelligence (ECCAI), President of the Association for Computational Linguistics, and is a EURAI and a AAAI Fellow.

Title: Automated persuasion and linguistic creativity

Abstract: Philosophers of language have taught us that at the basis of language production there is the intention to change the state of the world by intervening linguistically on other agents. Persuasion, being the process of influencing attitudes, beliefs, behaviors, mood of a target, is basically a matter of stronger emphasis. Argumentation is just one resource to persuasion, it has been studied since the times of Aristotle and now for quite some time in artificial intelligence.
In modern times we have witnessed also resorting to nonargumentative means, belonging to what is called the peripheral route to persuasion. Automated intelligent persuasion of the latter sort is a research area close to producing usable results, both through creative production of language expressions, and through other forms of communication. The theme is sensitive and so it is equally important to address ethical acceptability of persuading machines.
