Many interesting problems, including Bayesian network structure-search, can be cast in terms of finding the optimum value of a function over the space of graphs. However, this function is often expensive to compute exactly. We here present a method derived from the study of Reproducing Kernel Hilbert Spaces which takes advantage of the regular structure of the space of all graphs on a fixed num...

The structural details of a firm’s business processes are traditionally inaccessible to entities outside the firm. However, as firms move towards tighter coordination of processes with business partners, and system-level coupling between the processes of interacting firms, it is useful to share some features of the processes. In this paper, we show how the representation of business processes u...

This paper addresses the problem of eeciently updating a network of temporal constraints when constraints are removed from an existing network, or when they are added to it. Such processing tasks are important in many AI-applications requiring a temporal reasoning module. First we analyze the relationship between shortest-paths algorithms for directed graphs and arc-consistency techniques. Then...

Software as a Service (SaaS) is a new software delivery model in which pre-built applications are delivered to customers as a service. SaaS providers aim to attract a large number of tenants (users) with minimal system modifications to meet economics of scale. To achieve this aim, SaaS applications have to be customizable to meet requirements of each tenant. However, due to the rapid growing of...

Multi-tenancy is one of the most important concepts for any Software as a Service (SaaS) application. Multi-tenant SaaS application serves a large number of tenants with one single application instance. Complex SaaS application that serves significant number of tenants could have a huge number of customizations with complicated relationships, which increases the customization complexity and red...

Smalltalk is not only an object-oriented programming language; it is also known for its extensive integrated development environment supporting interactive and dynamic programming. While the default tools are adequate for browsing the code and developing applications, it is often cumbersome to extend the environment to support new language constructs or to build additional tools supporting new ...

We describe two domain-independent temporal reasoning systems called TimeGraph I and II which can be used in AI-applications as tools for eeciently managing large sets of relations in the Point Algebra, in the Interval Algebra, and metric information such as absolute times and durations. Our representation of time is based on timegraphs, graphs partitioned into a set of chains on which the sear...

Nowadays, the growth of virtual environments such as virtual organizations, social networks, and ubiquitous computing, has led to the adoption of trust concept. One of the methods of making trust in such environments is to use a long-term relationship with a trusted partner. The main problem of this kind of trust, which is based on personal experiences, is its limited domain. Moreover, both par...

The article deals with the issues of ontological engineering complex systems. Ontological includes processes designing and building ontologies, technologically combining object-oriented structural analysis. aims to ensure adoption high-quality management decisions by increasing level integration necessary information, improving search capabilities in databases knowledge bases, providing possibi...
