Most incremental mining and online mining algorithms concentrate on finding association rules or patterns consistent with entire current sets of data. Users cannot easily obtain results from only interesting portion of data. This may prevent the usage of mining from online decision support for multidimensional data. To provide ad-hoc, query-driven, and online mining support, we first propose a ...

the arc costs are assumed to be online parameters of the network and decisions should be made while the costs of arcs are not known. the policies determine the permitted nodes and arcs to traverse and they are generally defined according to the departure nodes of the current policy nodes. in on-line created tours arc costs are not available for decision makers. the on-line traversed nodes are f...

the present research is conducted to show that organizations can use wiki to attract customers' purchase intention inside the e-commerce context. considering the relation between wiki and ecommerce for crm, this research tries to explore the characteristics such as perceived risk, customer experience, knowledge sharing culture, trust and knowledge sharing in wiki tool impact on purchase in...

Claims have often been made that the quality of online customer experience web site ease of use, selection of goods offered, quality of customer service, the effectiveness of virtual community building, and site personalization are crucial to the success of e-commerce firms. If differences in the quality of online customer experiences provide a long-term competitive advantage, we would expect a...

We present T-UPPAAL — a new tool for online black-box testing of real-time embedded systems from non-deterministic timed automata specifi cations. We describe a sound and complete randomized online testing algorithm and how to implement it using symbolic state representation and manipulation techniques. We propose the notion of relativized timed input/output conformance as the formal implementa...
