%X After analyzing the principle of keywords and concept retrieval, a new vector space model named SC-VSM based on the semantic concept retrieval was proposed. Meanwhile, based on the combination of SC-VSM and keywords retrieval, an approach was presented in which the combination parameters can be adjusted according to different domains in order to obtain the best information retrieval result. Experimental results show that the SC-VSM is superior to the VSM, the cond3inative approach can not only reserve the advantages of keywords retrieval and concept retrieval, but also compensate for their shortcomings.
