Abstract:

To solve the problem of semantic gap in retrieving multimedia information, the definition and operation laws of matrix division method were presented, which describes the high-level semantic framework for many kinds of multimedia information. For the purpose of solving the problem of semantic gap for searching multimedia information, the high-level semantic framework was employed to retrieve multimedia information. Meanwhile, for this framework, a partial priority algorithm was proposed based on the results that each user retrieves multimedia information. The algorithm modifies adaptively the high-level semantic branch weights according to the results that each user retrieves multimedia information at each time. The retrieving efficiency is improved by the algorithm based on the framework.

Key words: computer software, highlevel semantics, multimedia, matrix division method
