— Web services are autonomous computing units which are identifiable, platform independent and accessible through the network with the standard web protocols. Nowadays web services are accepted as the standard way of distributed application development in the business world. But web services are usually discovered by humans and used statically by embedding into the developed application. However there could be many web services performing the desired functionality having different interfaces, and also new ones could be added in time. So it is required that those web services could be discovered automatically and executed dynamically by applications. On the other hand, in order to discover, compose, execute and monitor those web services automatically, they should be modelled using ontologies introduced with new generation web vision which is called the semantic web. Those web services are called as semantic web services. Hence some tools are needed to publish transforming existing web services to semantic web services and to discover, select, invocate, monitor them dynamically. In this work, a dynamic Web service invocation method has been proposed in order to carry out the Web service execution which is done by service clients using semantic messages. A Web service execution framework, which semantic Web services defined using SAWSDL can be dynamically invoked, has been developed. Also a case study in the field of customer relationships management has been performed in order to explain better the proposed method and to illustrate operation of the developed framework

Veb servisleri, tanımlanabilen, yayımlanabilen ve standart veb protokolleri ile ağ üzerinden erişilebilen platform bağımsız, özerk hesaplama birimleridir. Otomasyon arttığında veb servisleri insanlardan ziyade uygulamalar tarafından doğrudan erişilebilir hale gelecektir. Anlamsal betimlemeler ve bilgi yönetim teknikleri kullanılarak, servis yönelimli yeteneklerin keşif, birleştirme, yayımlama işlemleri daha detaylı bir seviyeye çıkarılabilir. Anlamsal veb servisleri kendi kendine yeten, bir ihtiyacı gidermek için bağımsız olarak tek başına ya da diğer anlamsal veb servisleri ile kümelenerek yeniden kullanılabilen yazılım bileşenleridir. Anlamsal veb servisleri, tam otomatik servis bulma, çağırma, birleştirme ve izleme işlevlerini desteklemek için veb servislerinin özelliklerini daha anlamlı ve yorumlanabilir bir şekilde ontolojiler yardımıyla tanımlar. Bu çalışmada, servis istemcilerinin, anlamsal mesajlar ile veb servis işletimi yapabilmeleri için bir dinamik veb servis çağrım yöntemi önerilmiştir. Önerilen yöntem için, SAWSDL kullanılarak tanımlanmış olan anlamsal veb servislerinin dinamik olarak çağrımlarının yapılabildiği bir veb servis işletim çerçevesi geliştirilmiştir.
