Multimedia Retrieval Based on Tagging Technology and Communities Performance Evaluation

Effective multimedia retrieval is the key to knowledge management and knowledge sharing for modern enterprises,but up to now the retrieval from multimedia documents is far from satisfactory for want of better technologies or technical solutions.With regard to the problems in keyword-based retrieval methods used on multimedia documents,this paper proposes a solution based on performance evaluation being executed by communities in a enterprise and tagging technology system and establishes an E-R model of the tagging system improved with performance evaluation for the document management platform.It presents a design of the business logic for the tagging system of the document management platform and provides an index assessment method for performance evaluation of the tagging.The purposeful integration of performance evaluation and tagging technology will guarantee the adequacy of the number and quality of the tags,and the efficiency and quality of the retrieval will be continually improved along with the system's self-learning,communities awaring and knowledge discovering on communities knowledge base,and this will surely satisfy the usual needs of most enterprises.
