Data quality issues have taken on increasing importance in recent years. In our research, we have discovered that many “data quality” problems are actually “data misinterpretation” problems – that is, problems with data semantics. In this paper, we first illustrate…

We address the problem of integrating objects from a source taxonomy into a master taxonomy. This problem is not only pervasive on the nowadays web, but also important to the emerging semantic web. A straightforward approach to automating this process…

A series-parallel directed acyclic graph, or SP-dag, contains nodes that are either in series or logically in parallel. We present a data structure and algorithm to efficiently determine, in a single serial walk of the dag, whether two nodes are…

Naïvement perçu, le processus d’évolution est une succession d’événements de duplication et de mutations graduelles dans le génome qui mènent à des changements dans les fonctions et les interactions du protéome. La famille des hydrolases de guanosine triphosphate (GTPases) similaire…

Malaria and diarrhea are major causes of illness and death in Africa. These preventable diseases take the biggest toll on children, mostly due to lack of education and adequate resources in the home. The purpose of the reported research project…

Conflicting reports have emerged as to whether entry of alpha-herpesvirus particles occurs by receptor-mediated membrane fusion or pH-dependent endocytosis, and whether the method of entry differs by cell type. At the other end of the virus replication cycle, it is…

We show how to interoperate, semantically and inferentially, between the leading Semantic Web approaches to rules (RuleML Logic Programs) and ontologies (OWL/DAML+OIL Description Logic) via analyzing their expressive intersection. To do so, we define a new intermediate knowledge representation (KR)…

The closing decades of the twentieth century saw a dramatic shift from institutional to community-based care for the mentally ill. This paper describes a study of the social representation of mental illness by mental health professionals working in Britain and…

The presented thesis discusses an investigation conducted into the improvement of employee experiences of stress in the workplace. It is estimated that 11.4 million working days were lost in 2008-2009 due to stress-related outcomes, and that stress was described as…
