Commercial services become increasingly important. Complex bundles of these services can be offered by multiple suppliers in a service value network. The eservice ontology proposes a framework for semi-automatically composing such a network. This paper addresses research challenges in service value network composition. As a demonstration of the state of the art, the eservice ontology is used. T...

Companies have increasingly focused on their own core business and created partnerships with other companies to increase their competitiveness. Linear supply chains of companies create the enterprise networks. The enterprise networks could produce wider product and service entities, and the entire network could be comprehended as a value adding value network for the product or service. VTT Indu...

Traditionally, the value of a product has been assessed according to the direct revenues the product creates. However, products do not exist in isolation but rather influence one another’s sales. Such influence is especially evident in e-commerce environments, in which products are often presented as a collection of web pages linked by recommendation hyperlinks, creating a large-scale product n...

Value guides behavior. With knowledge of stimulus values and action consequences, behaviors that maximize expected reward can be selected. Prior work has identified several brain structures critical for representing both stimuli and their values. Yet, it remains unclear how these structures interact with one another and with other regions of the brain to support the dynamic acquisition of value...

Different laws have been proposed for the value of a social network. According to Metcalfe’s law, the value of a network is proportional to n where n is number of users of the network, whereas Odlyzko et al propose on heuristic grounds that the value is proportional to n log n, which is the Zipf’s law. In this paper we have examined scale free, small world and random social networks to determin...
