Agenda • Crisis (Emergency) Management – Controlled Natural Language Component • Ontorion – Semantic Knowledge Management Framework • OASE - semiotic framework for software development www.cognitum.eu/semantics Cognitum | Semantics

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 www.cognitum.eu/semantics Cognitum | Semantics

EM Characteristics • Clearly defined orga ganiz izati ationa onal 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 www.cognitum.eu/semantics Cognitum | Semantics

Two Kinds of Knowledge Ontology / Fact-base Meta-ontology - Geo & topological - General knowledge derived information, location from legislative of rescue units, etc. issues, procedures, - Communication via disasters etc. graphical language, - Communication e.g. maps, building via CNL plans etc. (advanced GIS system) - Actors: management - Rescue actors experts www.cognitum.eu/semantics Cognitum | Semantics

EM Knowledge Management System - Objectives Comprehensive services enriched by posting / insertion of additiona onal l infor ormat mation ion from om the • environ onme ment The system should allow for the identificati fication on and analysis of new risks ks • Coordin inat ation ion and exchange e of infor ormat mation ion between the coordinator, e.g. at the municipal level • or at the regional level, emergency services and citizens Infor ormat 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 orm 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 ogy and therefore this tool will have great impact ct on the organizat nizational ional culture e itself www.cognitum.eu/semantics Cognitum | Semantics

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? www.cognitum.eu/semantics Cognitum | Semantics

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 www.cognitum.eu/semantics Cognitum | Semantics

EM Concepts Captured (2) Treatment system Communication & Infrastructure coordination (resources) (actors, procedures, tasks) Crisis characterization Studied world Crisis events, Environment effects, risks, (people, natural dangers sites, goods) www.cognitum.eu/semantics Cognitum | Semantics

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? www.cognitum.eu/semantics Cognitum | Semantics

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. www.cognitum.eu/semantics Cognitum | Semantics

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. www.cognitum.eu/semantics Cognitum | Semantics

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. www.cognitum.eu/semantics Cognitum | Semantics

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 of software entities and supports OASE-Annotations. www.cognitum.eu/semantics Cognitum | Semantics
