Ý nghĩa của hình ảnh trong truyền thông từ góc độ ký hiệu học

In the context of digital communication, images play an increasingly significant role in the transmission and organization of information. However, in journalism and communication studies, images are often approached primarily at the level of visible content or communicative effectiveness, while the mechanisms of meaning-making and signification have not been systematically examined. For this reason, semiotics is considered an important theoretical approach that enables the study of images as systems of signs operating according to social and cultural conventions. Based on this perspective, the article systematizes several prominent semiotic approaches in the study of visual communication and proposes an integrated semiotic framework for journalism and communication research in contemporary Vietnam.
