However, the well-known content-based image classification methods do not overcome the so-called semantic gap problem in which low-level visual features cannot represent the high-level semantic content of images. Image classification using visual and textual information often performs poorly since the extracted textual features are often too limited to accurately represent the images. In this paper, we propose a semantic image classification ap- proach using multi-context analysis. For a given image, we model the relevant textual information as its multi-modal context, and regard the related images connected by hyperlinks as its link context. Two kinds of context analysis models, i.e., cross-modal correlation analysis and link-based correlation model, are used to capture the correlation among different modals of features and the topical dependency among images induced by the link structure. We propose a new collective classification model called relational support vector classifier (RSVC) based on the well-known Support Vector Machines (SVMs) and the link-based cor- relation model. Experiments showed that the proposed approach significantly improved classification accuracy over that of SVM classifiers using visual and/or textual features.展开更多

Elzner provided more than 20 meanings of this word translated from Arabic. Music experts have decided in favor of the definition of word makom as ＂mode and genre＂. Establishment of makom as a genre had taken place approximately from 12th to 18th centuries. However, evolution of a mode system, had occurred much earlier. Makom art of Uzbekistan is a heritage, which had been formed over the long period. However, it has not yet reached its completion, it still keeps living and being filled with a new emotional mood, new image contents. Swift development of computer technology and communication means creates opportunities both for researchers and for performers to improve the phenomenon of the makom arts. Organization of various contests and festivals in Uzbekistan, makom performers＇ participation in foreign forums represents great incentives for showing the western interest in this arts and its integration into the global music science.展开更多
