Semiotics has enormous potential for integrating multidisciplinary analysis. First of all, it is about the processes of meaning formation and understanding, taking into account both their socio-cultural contexts and the role of the individual as the source, means and result of the cultural experience dynamics. This paper contains consideration of the opportunities for the semiotic conceptual apparatus expanding. Such opportunities are inherent in both the traditional concepts of semiotic "mainstream" and in concepts that bring semiotics into a wider and deeper context. The designated ideas circle extraction allows us to present the structure of the social experience semantic content systematically. This structure includes the sign material form, objective and functional social value, as well as the personal meaning (emotion-evaluative attitude and experience). It is not only about the components of the semantic content of social experience, but also about the system of their interconnection and interdependence. The transition from the material form of the sign to the objective and functional social meaning and further to the personal meaning, right up to the experience demonstrates the process of assimilation of social experience, its subjectivation, understanding.
