Quality criteria play an important role in WebServices as they differentiate similar services by qualities.Quality-based web services enable service requesters to chooseand bind to a suitable Web service at run time based on theirpreferred quality criteria.There are many quality criteria that are important to Webservices. This paper proposes a quality criteria classification thatorganizes web services qualities into four groups: performance,failure probability, trustworthiness and cost. The quality criteriaclassification is specified within the Web Service DescriptionLanguage (WSDL). The paper demonstrates an approach thatenables the Universal Description, Discovery and Integration(UDDI) to help business partners to discover services based onquality criteria by extending the current Web service architecturewith a quality server. The quality server uses a mathematicalmethod to facilitate and assist the requester to discover andselect the best available Web services.
