This paper describes a suite of tools developed at the University of Leeds which aim to make it easier for domain experts to be involved in the creation and use of ontologies. The paper summarises the main features of the tools and gives a short summary of our evaluations and experiences using the tools with domain experts. 1 Expressing Knowledge through a Controlled Natural Language At the cor...

Category: Site Characterization Presented at: The UXO/Countermine Forum, September 3-6, 2002, Orlando, Florida ABSTRACT There are different sources of uncertainty attached to UXO site characterization. One of them is associated with prior information regarding locations of ordnance targets, which are used initially for designing sampling schemes. The accuracy of information is then defined by t...

This demonstration will present the first stage of the ROO tool, a Protégé plugin that facilitates domain experts with little or no knowledge engineering experience to build ontologies. The ontology authoring process is assisted by offering task-driven suggestions and appropriate help, based on an ontology construction methodology developed at Ordnance Survey. The knowledge construction is furt...

The “Advanced Propellant/Additive Development for Gas Generator” project is a collaborative effort between General Dynamics Ordnance and Tactical Systems (GD-OTS) and the Naval Air Warfare Center-Weapons Division (NAWCWD). The objectives of this NGP project are to develop new highly efficient, environmentally acceptable, chemically active fire suppressant capabilities based upon solid propellan...

Abstract Marine environments are contaminated with enormous amounts of warfare agents due to military activity and exercise, the disposal unused ordnance. Due corrosion munition shells, substances leaking from materials into environment. It has be expected that climate change will influence distribution their content. Although there is no doubt about principle toxicity many compounds, including...
