Abstract


With the development of communication technology , communication transmission capacity has been able to meet the the richer upper business needs . In many emerging business the remote multimedia conferencing services to meet customer demand , and at the same time can make full use of network bandwidth telecommunications business . At the same time , today 's communications business moving in the direction of the development of intelligent and On Demand . Semantic Web technology as an extension of an existing web is the key to a new generation of Internet technology , has the semantic commonality as well as network intelligence . SOA technology as an IT architectural style , its loose coupling and service reusability for modern software systems has brought revolutionary changes . How existing multimedia conferencing system integrated into the SOA technology and semantic web technology to become a new research topic . In response to these problems , this paper presents the architecture of a SOA-based multimedia conferencing system operators ontology reasoning technology program . In this architecture , the system has two types of multimedia conferencing scenarios . Will notice , the President by entering basic information about the meeting , the system automatically selects the appropriate basis for meeting time and participants Contact notification will notice ; second category is speaking in the meeting , the system based the priority name speakers automatically award and choose the right speakers for speech . In the system , the various types of telecommunication services are encapsulated into web services and deploy ESB Enterprise Service Bus , BPEL technology application process , making the two types of applications composed of two complete service . Applications in addition to the SOA technology also integrated into the Semantic Web ontology reasoning techniques . Corresponding business rules by creating a large body of multimedia conferencing , the body design , a scene based on ontology reasoning . In addition , the the ontology reasoning redundant data management issues , as well as a large body , the paper proposes a multi-source point segmentation algorithm based on the breadth-first , you can successfully cut off the redundant part of the body and to ensure the validity of the reasoning . Finally, this paper shows before the design of business processes to achieve results , and the corresponding test experimental analysis . And proposed a further expansion of the two technologies in multimedia conferencing system and application direction .
