Anomaly-based techniques were exploited successfully to implement protection mechanisms for various systems. Recently, these approaches have been ported to the web domain under the name of "web application anomaly detectors" (or firewalls) with promising results. In particular, those capable of automatically building specifications, or models, of the protected application by observing its...
Bayesian networks (BNs) are probabilistic graphical models that are widely used for building diagnosis- and decision-support expert systems. The construction of BNs with the help of human experts is a difficult and time consuming task, which is prone to errors and omissions especially when the problems are very complicated. Learning the structure of a Bayesian network model and causal relations from...
IntegraL is a digital library system demonstrating a lightweight system integration technique for digital library collections and services. Digital library systems generally require integration with minimal or no changes to their code. IntegraL users see a totally integrated environment. They use their digital library system just as before. They also see extra link anchors. Selecting one generates...
Sem@ntica is a system for extracting the information contained in collections of documents into a knowledge base. It combines high quality conventional named entity analysis with an ontology class labeling capability for open class words. The ontology comprises an upper ontology and one or more domain ontologies. The system has tools for rapidly designing the ontology and mapping segments of Word...
