Sheffield Focus


Human language Technologies (HLT) &
Knowledge Management



Where can HLT impact the KM lifecycle?



What Technologies for what task?



Effects in using HLT in the KM lifecycle?


Portability & Usability



HLT
-
based Systems portable to new
applications by non HLT experts


User Centred Methodologies




HLT
-
based systems that automatically adapt to
user needs and requirements

Sheffield’s Research and Application Areas

An example scenario for using HLT for Knowledge Management:
monitoring product quality in the market: HLT allows accessing
knowledge dispersed in texts
