Abstract


Web service is a kind of special application which is deployed on the Internet. It provideseffective solutions for the realization of data and system interoperability in a certain technicalspecifications. With the increasing perfection of web service technology, in order to achieve businessvalue, more and more enterprises and commercial organizations take its business functions andcomponents packing into web service issued to the network. However, a single web service onlyprovides some relatively simple function. In most cases it already cannot satisfy the currentcomplicated network environment demand. So it is need to combine existing web services to form anew value-added web service. Web service combination problem has become a hotspot of currentresearches.In this paper, the author studied Web service combination algorithm, and put forward the roughset into the genetic algorithm in combination of Web service method. At first the paper established notfunctional attributes which the web service need. During this part the author uses rough set to addedmissing attribute, then standardizing types of each attribute; At last, combined with objective andsubjective two aspects, comprehensive QoS attribute weight is given. In the genetic algorithm in thispaper, the traditional genetic algorithms are certain to improve, the first coding method usingtwo-dimensional matrix coding mode and overcome the one-dimensional coding mode that it can’t sayweb service combination path; Then using rough set theory formation reduction rules to reduce theinitial population and crossover and mutation caused offspring population area. In the evolutionaryprocess the paper uses crossover and mutation probability which is changed by population diversity. Itcould avoid algorithm premature and ensure the global optimal. Finally, through constant iterative, thebest web service combination optimal solution which is best satisfied by users is come out. Based onour experimental results, this approach has shown great promise and operates effectively.
