AB  - The advancement of Web Services (WS) and applications leads 
  to the publication of numerous web services with similar features. Quality of 
  Service (QoS) has become a key factor in selecting a right service from the 
  huge collection of similar web services. Latterly, evolved semantic based approach 
  OWL-S provides expressive functional description and discovery but it fails 
  to support the QoS specifications in service description. To overcome the aforementioned 
  issues, researchers present a novel framework called Trustworthy Semantic QoS 
  based web service description and discovery (TSQoS). The proposed framework 
  has two prominent features that differentiate it from other existing work in 
  this research area. First, capability profile provides more expressive QoS aware 
  functional descriptions through corresponding semantic ontologies that support 
  new Capability Attribute Semantic Matchmaking (CASM) to return functionally 
  matched web services. Second, to achieve automatic service discovery, adaptive 
  trust-aware service selection is proposed based on user’s 
  trust policy that implements a service executor. It computes actual QoS provided 
  by the service from the objective values provided by QoS monitoring entities 
  along with subjective evaluations (User feedback) provided by service consumers 
  from their past experience. It also presents an efficient mechanism to determine 
  the actual QoS by considering both published QoS description and computed eminence 
  score. Thus, a service with high eminence score is returned as best service 
  which can provide actual QoS required by the user. Finally, the experimental 
  result shows that the proposed TSQoS based WSDD approach achieves increased 
  precision and recall compared to existing QoS based WSDD approach.
