An Integrated Approach for Modeling Ontology-Based Task Knowledge on an Incident Command System

Abstract

This paper presents the TTIPP methodology, an integration of task analysis, task ontology, integration definition function modeling (IDEF0), Petri net, and Petri net mark language (PNML), to organize and model the task knowledge in the form of natural language expressions acquired during the knowledge-acquisition process. The goal of the methodology is to make the tasks more useful, accessible, and sharable through the web for a variety of stakeholders interested in solving a problem which is expressed mostly in linguistic form, and to shed light on the nature of problem-solving knowledge. This study provides a core epistemology for the knowledge engineer while developing the task ontology for a generic task. The proposed model overcomes the drawbacks of IDEF0, which are its static nature and Petri net which has no concept of hierarchy. A good number of countries lie on the typhoon and earthquake belts, which make them vulnerable to natural calamities. However, a practical incident command system (ICS) that provides a common framework to allow emergency responders of different backgrounds to work together effectively for standardized, on-the-scene, incident management has yet to be developed. There is a strong need to explicitly share, copy, and reuse the existing problem-solving knowledge in a complex ICS. As an example, the TTIPP model is applied to the task of emergency response for debris-flow during a typhoon as a part of an ICS.

Ontology-Based Knowledge Modeling of Muli-factors for Severe Weather Risks in Snow Sports

“…Based on the triangle theory of public safety [6], weather conditions are not the only source of meteorological risk, the geographic environment characteristics of snow sports venues [7,8], the vulnerability of the objects within the range of action [9], and the emergency response capabilities [10] also influence the development and evolution of severe meteorological events. Determining all knowledge related to severe weather events in snow sports is a key prerequisite for the comprehensive and integrated meteorological risk assessment.…”

Study of a BIM-Based Cyber-Physical System and Intelligent Disaster Prevention System in Taipei Main Station

“…The ICS is a special method for composing and controlling the employment of many highly reliable temporary organizations and public safety professionals to manage various resources in an emergency. ICS is mandated by all responding organizations in the United States to respond to routine and large-scale hazard events [18,19]. The actual use details and usefulness of the system are not known.…”

TKRM: A Formal Knowledge Representation Method for Typhoon Events

“…Compared with a generalized event representation, there are several factors that require more consideration in a typhoon event: (1) A typhoon is a geographical phenomenon, therefore time and location are the basic conditions for its existence. In the existing event models, time, location, and other attributes are juxtaposed, which do not reflect the characteristics of time and location as the basic framework [30,31]. (2) Describing the dynamics of events by depicting changes in states or intervals is still equivalent to recording a snapshot of an event at different time segments.…”
