• Crisis (Emergency) Management – Controlled

Natural Language Component

• Ontorion – Semantic Knowledge Management

Framework

Problems Addressed – Emergency, Crisis Management (EM)

• activity of public administration, a part of national

security management

• dealing with the strategic organizational management

processes (an integrated rescue system) used to

– pr prevent critical situations (crises), – pr prep epar are to assume control of crises by way of planned activities, – respo pond nd in case of emergencies, remove their effects and restore the resources and critical infrastructure

EM Characteristics

• Clearly defined orga

ganiz izati ationa

• nal

l st struct cture

• Legi

gisl slati ative ve issues and documentation

• Different kinds of information: time

me (information can vary in time), sp space ce

• Different requirements to information acc

ccess ssibil bility ity & & pr prese senta ntation ion (by different actors)

• Rescue actions: time pressure, usually lack

ck of f necessary reso sour urces ces

Two Kinds of Knowledge

• Geo & topological

information, location

• f rescue units, etc.
• Communication via

graphical language, e.g. maps, building plans etc. (advanced GIS system)

• Rescue actors

Ontology / Fact-base

• General

knowledge derived from legislative issues, procedures, disasters etc.

• Communication

via CNL

• Actors:

management experts Meta-ontology

EM Knowledge Management System - Objectives

• Comprehensive services enriched by posting / insertion of additiona
• nal

l infor

• rmat

mation ion from

• m the

environ

• nme

ment

• The system should allow for the identificati

fication

• n and analysis of new risks

ks

• Coordin

inat ation ion and exchange e of infor

• rmat

mation ion between the coordinator, e.g. at the municipal level

• r at the regional level, emergency services and citizens
• Infor
• rmat

mative ve issues s involving the public: alarm system, forums, educational platform, opinion monitoring, surveys

• Traini

ning ng & simulat lation ion platform

• EM-KMS accessed via spectrum of CNL (Controlled Natural Language) interfaces

can be seen as a commu munica icatio ion n platform

• rm that allows for constant

nt contact act between coordination actors without additional UI layer (and training)

• It is expected that CNL will force actors of coordination to use the precise

statements as well as strictly defined ed and stand ndar ardiz dized ed termino minology

• gy and therefore

this tool will have great impact ct on the organizat nizational ional culture e itself

EM – what knowledge needs to be managed?

• What procedures need to be applied?
• What actions/tasks are undertaken within the process?
• What actors are involved in certain actions (actors’

dependancies, division of responsibilities) ?

• Geo related issues:

– What is the location of the emergency or crisis event? – Where are the rescue teams during crisis events? – What environmental factors influence the course of crisis events? – Where to find shelter during the crisis event?

EM Concepts Captured – Meta-ontology (1)

• Organiza

anizatio tional al str truct uctur ure: e: roles (actors and units) and their relationships

• Responsibil

nsibilities ities of actor tors s for certain tasks in a particular situation

• Aler

erts ts about crisis risis situations and danger ers

• Informat

rmatio ion about crisis isis event nts, s, effects, ects, risks sks and danger ers

• Acti

tivit vities ies / Proced cedur ures es that are performed in specific situations during prevention, preparation, response to crisis and recovery

• Resour

urces ces, devices and equipment useful for performing rescue actions

EM Concepts Captured (2)

Infrastructure (resources) Communication & coordination (actors, procedures, tasks) Crisis events, effects, risks, dangers Environment (people, natural sites, goods)

EM Use Case – Tanker Accident

A tanker truck (containing unknown toxic substance) had an accident. Several children of the near kindergarten (outside when the accident happened) feel sick.

• What are the dangers?
• What services we need

to call?

CNL - SWRL rules

If Z is an actor and if a crisis has-type a crisis-type and if Z reacts-to-type the crisis-type then the crisis needs-actor Z. If Z is an actor and if an effect causes a danger and if a crisis induces the effect and if Z assumes a procedure and if the procedure reduces the danger then the crisis needs- actor Z. If Z is an actor and if an effect concerns a people-group and if a crisis induces the effect and if it is true that the people-group has-victims and if Z is Emergency- Medical-Service then the crisis needs-actor Z.

OASE - Ontology Aided Software Engineering

Ontology-Aided Software Engineering (OASE) is a semiotic framework for software

• development. It extends the existing methodologies with an ability to express the

supporting knowledge in (controlled) natural language called OASE-English.

OASE-Annotator

OASE-Annotations and OASE-Assertions allow for the protection of the programmer from breaking the design-time or runtime assumptions and can be checked by the reasoning services (OWL-Reasoner) in terms of consistency and preservation of logical constraints.

OASE-Diagrammer

OASE-Diagrammer adds the ability to use the UML, together with the OASE framework. OASE-Diagrammer is dual to OASE-Annotator. It allows to draw the UML representations

• f software entities and supports OASE-Annotations.
