Resum:

Malgrat els avenços recents de la intel·ligència artificial i fins i tot les veus que auguren els seus "perills", la realitat és que la semàntica i pragmàtica del llenguatge segueixen sent un gran repte per als sistemes automàtics de processament del llenguatge natural (PLN). En aquesta xerrada exemplificaré aquest repte a través de dues tasques de PLN: la resolució de la coreferència i els sistemes de diàleg. Oferiré una descripció general d'aquestes tasques juntament amb estudis recents i exemples per il·lustrar quins aspectes semàntics estan resolts i quins són encara el focus de la recerca actual, especialment des de la perspectiva de les aplicacions de PLN en productes comercials.

 

Biografia:

La Dra. Marta Recasens és investigadora a Google des del 2013. Anteriorment va ser investigadora postdoctoral a la Universitat de Stanford i membre del Stanford NLP Group. Va obtenir el doctorat en Lingüística a la UB l'any 2010 amb una tesi sobre la resolució de la coreferència. La seva investigació se centra en aproximacions empíriques i aplicades a la semàntica i pragmàtica del llenguatge des de la Lingüística Computacional.

Abstract:

Dramatic progress has been made over the last 2 decades in how we access key types of biological data - in particular sequence-based data on genomic information. However, integrating this data to produce dynamic and predictive models of higher level biological phenomena (e.g. development, regeneration, homeostasis and cancer) has been limited. Questions about tissues and organs are still most often tackled at the molecular or cellular level. We tend to ask how individual progenitor cells respond to signals from their “environment”, and thus to focus on signal transduction pathways, gene regulatory events, and epigenetic memory. But an organ is more than just an environment for cells to “act” in – it is an integrated whole, a coherent community, with cells in constant genetic, chemical and mechanical communication with each other. New technical advances such as organoid culture, 3D mesoscopic imaging, multicellular omics and computer modeling are helping us to go beyond the molecular and cellular level, to understand multicellular feedback loops, long-range signalling networks and emergent collective decisions, and thus to see tissues and organs as systems in their own right. Modelling these higher-level processes in vitro and in silico will help us understand these complex processes at a deeper level, and I will discuss our own attempts in this direction, to understand one example of complex organogenesis – namely mammalian limb development.

SONIA TRIGUEROS

CODIRECTOR OF THE INSTITUTE OF NANOTECHNOLOGY, UNIVERSITY OF OXFORD

Nanotechnology is a new and exciting field that has the potential to transform the way medical and health solutions are being developed. In the Department of Physics, my group investigates new techniques and materials at a nanometric scale. In the Department of Zoology, my group applies this knowledge directly to know the most relevant biology on a single molecule scale and then use science and technology to solve the most urgent medical problems of the 21st century. During the talk, I will focus on describing the field of nanotechnology, current applications and the potential of future applications. I will also explain the latest basic research projects and medical applications that we are developing.

 

Bio: The group of Sonia Trigueros focuses on the design of the new system of distribution of genes and drugs to specific cells. It is also developing new nanomedicines to address the problem of resistance to bacterial antibiotics. She is a doctor in molecular biology for the IBMB-CSIC and the University of Barcelona. After his postdoctoral research scholarships at Harvard and Oxford Universities, Trigueros was visiting research at various academic institutions, including NIH-Washington and the University of Havana. He is currently an associate researcher at the Department of Zoology and the Department of Physics and co-director of the Oxford Institute of Martin NanoMedicina at the University of Oxford.
