AIC Seminar Series

Hybrid Semantic Resources

Alessandro OltramariLaboratory for Applied Ontology, Institute of Cognitive Sciences and Technologies, CNR[Home Page]

Notice:  Hosted by Vinay Chaudhri. Note the non-usual day (Monday)

Date:  Monday, June 28th 2010 at 4:00pm

Location:  EJ228 (SRI E building). slides via WebEx from 3:45pm on, sound at 1-888-355-1249, 749045  (Directions)


“Ontologies”, i.e. formal specifications of shared conceptualizations, provide rigorous representations of human knowledge, allowing for automatic reasoning when encoded in computational languages; “electronic lexical resources” aim at machine-understandability of linguistic units. The interface between these two kinds of resources is an efficient solution for exploring “Semantic Reality”, where human and artificial agents negotiate meanings and exchange knowledge contents. This integrated solution provides a “breeding ground” to knowledge engineers for modeling the cognitive dimension of meanings. The interplay between computational ontologies and electronic lexical resources (especially WordNet and FrameNet) is also important for content-access in human-computer interaction scenarios. In my talk I will present the general framework, methodological issues and design principles related to the construction of these “hybrid semantic resources”. I will also outline a proposal for incorporating information on linguistic metaphors in such integrated systems.

   Bio for Alessandro Oltramari

Alessandro Oltramari (Vicenza, 1976) graduated in Philosophy of Science at the University of Padua in 2000 and received a Ph.D. in Cognitive Science and Education at the University of Trento in 2006. He has been a Research Fellow at CNR (National Research Council) since 2000. He currently collaborates with the ISTC-CNR (Institute of Cognitive Science and Technologies), at the Laboratory for Applied Ontology (LOA) in Trento - mainly on the integration between semantic and linguistic technologies. He is a permanent member of the organising committee of the international workshop series "OntoLex" - Ontologies and Lexical Resources. He has been "Visiting Research Associate" at the Princeton University (USA) in 2005 and 2006, guest of the Laboratory of Cognitive Science (WordNet group). He participated to several national and international research project. He is author of about 40 scientific papers in the field of formal and applied ontology, computational linguistics, cognitive science, knowledge management. He has edited 2 books for major international publishers (one is in progress) and 3 books of workshop proceedings, has given about 10 invited talks. He has been member of the program committees of major international conferences in the fields of formal and applied ontology, linguistic resources and semantic technologies. From January to September 2007 he also collaborated with Cogito S.r.l., a satellite firm of Expert System, a leading international provider of semantic technologies. In march 2008 he started a collaboration (teaching & research) with TeSI laboratory (Technology and Systems of Firms), part of the Department of Management and Engineering (University of Padua).
