Information Extraction and Transport, Inc. (IET) is developing the Knowledge Elicitation Environment for Probabilistic Event and Entity Relations (KEEPER) system, a tool for eliciting, storing, updating and implementing probabilistic relational models (PRMs)[1,8,16]. The KEEPER elicitation component implements a single ontology for the purposes of(More)
Among the lessons learned from recent conflicts stands the dramatic change in the very way wars are fought. There are no more clear-cut enemies or allies; rules of engagement have become increasingly fuzzy; guerrilla and insurgent tactics are now commonplace: in short, the battlespace is a very different place from what it used to be. Furthermore, advances(More)
Decision support and information fusion in complex domains requires reasoning about inherently uncertain properties of and relationships among varied and often unknown number of entities interacting in differing and often unspecified ways. Tractable probabilistic reasoning about such complex situations requires combining efficient inference with logical(More)
Two security domains that want to exchange information securely may need to agree on translations of Mandatory Access Control (MAC) labels of their information, if their MAC labels have a different syntax or semantics. It is desirable that these translations do not introduce any confidentiality violations. In this paper we present a property, the Security(More)
The theory of error-correcting codes arises from the following problem: What is a good way to send a message across a noisy channel? The investigation of this problem has many manifestations in communications and computer technology. Perhaps the most familiar application is the spectacularly successful Compact Disc player, which uses Reed-Solomon codes to(More)
Like other power systems in the world, most of the voltage dips in Hong Kong are caused by thunderstorms, lightning, vegetation intrusion, third party interference and heavy load switching. In some cases, voltage dip may lead to interruption of major advanced building facilities inside the building like tripping and sudden stoppage of chiller plant and(More)
Little is known about the experience of Chinese parents of children diagnosed with autism spectrum disorders (ASD) living in the Hong Kong Special Administrative Region. Seventy-five parents of children (aged 6 months-18 years) with ASD diagnoses completed the Family Quality of Life Scale. Forty-five parents from the original surveyed cohort, also(More)
Workflow systems provide automated support that enables organizations to efficiently and reliably move important data through their routine business processes. For some organizations, the information processed by their workflow systems is highly valued and in need of protection from disclosure or corruption. Current workflow systems do not help(More)
