D2.1 Requirements and Specification - CORBYS

D2.1 Requirements and Specification
Requirement No.: DMO5
Name: Device state integration with Device State Integrator (DSI)
Description: Device ontology to assist device state integration
Reason / Comments:
Indicative priority Mandatory
7.3.2 Assumptions and Dependencies
� Modelling the device ontology depends on input from partners regarding selected sensors and
actuators, other devices to be used in CORBYS
7.4 Self­Awareness Realisation (Task 4.2, UR)
Self-Awareness supported by Situation Assessment is an essential part of a cognitive system. It allows the
system to interact with the environment in the most efficient and sensible way without the interference of an
external guide. The CORBYS Situation Assessment Architecture facilitates (i) awareness of available sensors
and actuators (via the device ontology) and (ii) awareness about the relationship of these devices to the
environment including humans. CORBYS Situation Assessment Architecture includes a number of modules
such as semantic integrators for person, device/object/entity, ontological layer for devices, domain specific
(Plug and Play) ontologies and a blackboard structure acting as a globally accessible facility for situation
assessment.
A Device State Integrator (DSI) acts as the interface or interpreter between the sensors/actuators and the core
system, using the information in the device ontology. DSI fuses all the information and makes it available to
the core-architecture for further processing via the blackboard.
Awareness about the relationship to the environment entails positioning, interaction possibilities with the
environment, potential workflows, process flows, process maps, etc. This information is provided by an
Object State Integrator (OSI) which analyses the received input information from sensor data and creates a
cognitive image of the environment.
A Person State Integrator (PSI) allows for the representation of the interacting person, including information
such as position of the person, profile integration etc.
The integrated Situation-Awareness Blackboard (SAWBB) in CORBYS allows access to designated deviceagents
for relevant updates of profiling knowledge as well as the person’s current states, events, and
behaviours detected by all the sensor and reasoning sub-systems. It serves to facilitate symbolic knowledge
integration and inferencing at the higher semantic fusion, and enables appropriate dynamic data/knowledge
sharing regarding the semantic parametric values of the situated operational context.
SAWBB is a layered architecture supporting the sharing and integration of data at various levels of abstraction
including raw data from sensors etc; the upper layer being in the form of an event handler/look up table and
the second layer taking the form of a database to store historic and profiling information. SAWBB is a part of
the high level Cognitive CORBYS control architecture; the connection of the Situation Assessment
Architecture with the module responsible for perceiving, focusing, cognition, learning and responding to
environment. An important part of this module is the internal representation of the robot internal self-model
and self-state awareness which allow the system to reason and act based on its status, the context of assigned
task and event anticipation. Two types of memory will be realised, i.e. one representing the current state of
