There are also some proposals such as DAML-S, which is a part of DARPA Agent Markup Language project that aims at realizing the Semantic Web concept. DAML-S has been adopted to automatic service discovery, composition, execution and monitoring of Web services. However, DAML-S is a complex procedural language for Web service composition. Because Web services can be provided by third parties and invoked dynamically over the Internet, their QoS can vary greatly. Therefore it is important to have a framework capturing the QoS abilities of Web Services during finding/discovering the Web service as well as composing integrated Web Service. The global selection approach enables us selecting Web Services by their non-functional characteristics (QoS) in dynamic peer-to-peer environment. There are many aspects of QoS important to Web services. The work has been started to organize them into QoS categories [6]. Each category needs to have a set of quantifiable parameters or measurements. Further research is needed in this area. The advantage of global selection approach is that it correlates with Web services technology basis and could be easily extended to capture other linear-expressed quality metrics (e.g. QoBiz and QoE). 4.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
