Method and apparatus for characterizing cultural symbols

Abstract

The present disclosure proposes a method for characterizing cultural symbols by using a machine learning model, including: receiving multiple materials about a symbol unit, wherein the multiple materials at least include a picture drawing the symbol unit, pronunciation of the symbol unit, and an image or a video showing cultural meaning of the symbol unit, and the symbol unit is a single cultural symbol or a combination of multiple cultural symbols; for each material of the multiple materials, analyzing and learning the material to extract features of the material to form a set of feature vectors; fusing all of the formed feature vectors into a tensor; and analyzing and learning the tensor to generate a concept vector characterizing the symbol unit, wherein the concept vector is directly and consistently associated with the symbol unit. The method can characterize a broader range of cultural symbols, and can be used for multimodal information retrieval.
