“…A survey of three typical semantics processing techniques (relevance feedback, machine learning, and ontology) is presented in [71]. Typical semantics based 3D retrieval approaches include relevance feed back [72], semantic labeling [73], neural networks [74], supervised [75 78] or semi supervised [79 81] learning, boosting [82], proto types [83], autotagging [84], spectral clustering [85], manifold ranking [86], semantic tree [87], feature dimension reduction [88], semantic subspaces [89], class distances [54], semantics annotation of 3D models [90], semantic correspondences [91], and sparse structure regularized ranking [92].…”
