This invention relates to the field of
big data service technology, specifically to an automated
report generation system and method for free editing and
parsing of multimodal templates. The invention first constructs a template structure relationship diagram and a
business data hierarchy diagram, then iteratively calculates the final matching probability matrix between keys and placeholders to determine all mapping combinations between keys and placeholders; further, it determines whether to generate anti-fragmentation
layout tags; then, based on the mapping combinations, it writes the
business value corresponding to the key name into the first
source text node of the cleaned placeholder text node set, determines whether to attach anti-fragmentation
layout tags, and serializes and outputs the report file. This invention overcomes
parsing failures caused by fragmented underlying template tags; it integrates literal and topological hierarchy features to achieve accurate mapping of complex heterogeneous data; and it dynamically injects anti-fragmentation tags for
multimodal data, solving the problem of chart truncation across pages, significantly improving the accuracy and
layout quality of automated
report generation.
