Abstract
A review of search and selection of software components and services over a network is presented. In particular, we review techniques based on fuzzy weighted descriptors of components. These techniques allow developers of a new application to submit a query over the network to search the most suitable candidate component for reuse. The syntax and semantic of descriptors and of “adaptability” based on fuzzy calculus are given together with an example of on-line search of components via a site implementing a Fuzzy Trader. We describe an architecture, based on a Trader, storing a hierarchy of descriptors allowing to represent both functional and non-functional features of the networked components and services.
