- Accessing and Computing Meaning, por VICTOR RASKIN (Distinguished Professor, Purdue University, USA) no dia 17 de Março de 2015, hoje, pelas 14h no Auditório ILCH.
Abstract As the fear of semantics is declining, let’s formalize the unformalizable! The address focuses on the feasibility and necessity of accessing directly the comprehensive meaning of natural language texts, data, images, etc., to emulate human understanding by the computer. It is based on the premise that, without such understanding, no real-life application can reach the precision that human users of computational systems require. Moreover, meaning access and processing goes well beyond natural language applications, even as the scope of those keeps growing.
The main obstacle for this seemingly reasonable goal is the widespread prejudice against meaning as unknowable in principle because it is “subjective,” context-sensitive, complex, messy, etc. This has not been our experience, and it is worth talking, both practically and theoretically, about the know-how that a research group should acquire to approach the processing tasks semantically. A convincing case can be made for the feasibility and affordability of the approach as well, especially in the light of our planning to make our resources Open Source, a plan that may be followed by other computational semanticists.
It is hoped, therefore, that this address will further reduce the fear of, and prejudice against, semantics.
- What can we learn from computers’ (not) understanding humor?, por JULIA M. TAYLOR (Assistant Professor, Purdue University, USA) no dia 18 de Março de 2015, quarta-feira, pelas 14:30h no DI-A2.
Abstract Humor-centered computing is impossible without humor. In order for it to have humor, humor must be formalized and made computable. For it to happen, there must exist a theory of humor suitable for computation. For a quarter of a century, the humor community has thought there was a reliable formal linguistic theory: on a full comprehension of its nature, it has allowed for reasonable consensus on joke analyses and their reproducibility by human experts.
With the development and availability of semantic computing, however, it has become clear to the principals that the theory is not quite adequate. The talk focuses on elevating the currently dominant formal theory of humor to a level suitable for computational use and developing a computational system capable of understanding the joke mechanism. This mechanism will enable the computer to provide a punch line to a human generated setup (even if unintentional) and conversely, to react competently to a human generated punch line that follows a setup that is generated by either participant. The talk will utilize the Ontological Semantic Technology resources and algorithms that are applied to comprehensive meaning representations of jokes and individual preferences for them.
