| WSV - Research Topics |
| General Overview |
|
| The knowledge and language processing group (WSV) at the Department of
Informatics
at the University of
Hamburg investigates higher cognitive processes like language
understanding and production, inference drawing, problem solving as well as
learning and knowledge acquisition. |
| The research is carried out from an interdisciplinarily point of view: methods
of Computer Science/Artificial Intelligence are added by methods and findings
from Linguistics, Psychology and Logic. |
| The aim of the investigations undertaken by this research group is the
development of mathematical/formal models for cognition, the evaluation of these
models by system simulations, and the conception and realisation of application
oriented AI-systems on the basis of Cognitive Science. |
| The knowledge and language processing group WSV used to cooperate with the
Graduiertenkolleg
Kognitionswissenschaft, a doctoral programme in Cognitive Science
at the University of Hamburg until its end of funding in September 2000. |
| The knowledge and language processing group WSV is involved in the
International Research Training Group CINACS. |

| Main research topics |
|
| Knowledge representation of time, space, and events |
| Representations of the real world concern in particular the anchoring of
objects and situations (events) in space and time. Only if the spatial and
temporal properties and relations of objects and events are represented
adequately, it is possible to unterstand, plan, explain and carry out events in
the real world. This research group therefore develops general procedures for
representing and processing knowledge about space, time and events and tests
them in exemplary domains. |
| Representation of objects and concepts |
| This area of interest looks into the part-whole-structure of entities and the
relation between structure and category membership. Principles of wholeness and
integrity which are fundamental for the development, representation, and
processing of concepts as well as strategies for the representation and
processing of form and gestalt of objects are investigated. |
| Understanding and production of language |
| Natural language processes (i.e. understanding and producing utterances or
text) are regarded as specific cognitive processes that interact with othr
non-linguistic cognitive processes. It is assumed that a cognitive foundation
that is reflected by the design of NL systems is advantageous not only from a
purely scientific point of view but also considering productivity and
transferability of these systems in the long term. |
