Therefore, choosing appropriate web services to achieve specific goals requires a certain amount of knowledge as well as expertise. In order to support users in choosing appropriate web services it is not only important to match their search criteria to a dataset of possible choices but also to rank the results according to their relevance, thus minimizing the time it takes for taking such a choice. Therefore, we investigated six ranking approaches in an empirical manner and compared them to each other. Moreover, we have had a look on how one can combine those ranking algorithms linearly in order to maximize the quality of their outputs.", address = "Wrocław, PL", booktitle = "Proceedings of the 7th International Conference on Evaluation of Novel Approaches to Software Engineering (ENASE 2012)", isbn = "978-989-8565-13-6", keywords = "Mashup;Web Service Composition;Ranking", publisher = "SciTePress", title = "{R}anking {W}eb {S}ervices using {C}entralities and {S}ocial {I}ndicators", year = "2012", }
