Abstract. This paper present the details of participation of DEMIR (Dokuz Eylul University Multimedia Information Retrieval) research team to the ImageCLEF 2012 Medical Retrieval task. This year, we evaluated impact of our proposed Integrated Combination method and Explicit Graded relevance feedback on the most descriptive low level features of images and best text retrieval result. We improved results by examination of different level of integrated approach for retrieved text data and low level features. We tested multi–modality image retrieval in ImageCLEF 2012 medical retrieval task and obtained the best rank in visual retrieval due to our experiments. The results clearly show that proper combination of different modalities improve the overall retrieval performance.
