The invention discloses an AI-based multi-
modal digital content intelligent recommendation method and
system, relates to the technical field of
artificial intelligence and education recommendation, and is used for solving the problems of inaccurate matching of multi-
modal learning resources and user intentions, false feature interference and unclear semantic links in a weak network scene. Firstly, intention analysis and
user modeling are carried out on user multi-
modal interaction behaviors through a
large model, and user feature vectors with unified dimensions and stable calibers are formed; and the resource side extracts semantic and
time sequence features, and introduces preview elf chart recognition in a weak network scene. In order to suppress false features, a minimum evidence account book and a three-point co-location check chain are provided, and accounting management is carried out on evidence lease; and
main channel writing is released only when the real frame backbone is consistent with the
subtitle key points. Then combining modal gating fusion, knowledge network anchoring and path construction, and finally implementing hierarchical reordering according to the reference
semantic vector and the
incidence matrix to generate a traceable, verifiable and robust personalized recommendation result.
