%X Flexible expressing mechanism is an important factor influencing system performance in contentbased retrieval, the simple mechanisms current systems employed can not express complex content queries. In this paper, an intermediate query expressing mechanismCbExpr is proposed. The mechanism first maps each content query to a similarity distribution function in feature space, then approximates this function using basic single feature queries. Basic thoughts and examples are given, also with implementation on Internet/Navigator platforms.
