Chinese opera text analysis and drama abstract extraction method

The invention relates to a method for Chinese opera text analysis and drama abstract extraction, and relates to the field of Chinese opera analysis. In the application, a traditional opera text generation network synthesizes time-aligned multi-modal contents of traditional opera videos, audios and scripts through a plurality of single-mode encoders and a modal fusion network to generate a traditional opera text; performing text segmentation on the obtained opera text according to semantics, encoding segmented text contents through an Embedding model to obtain vector representations of the segmented text contents, and forming a content vector library of the opera text by the vector representations; obtaining a question vector related to the drama abstract, and obtaining a Chinese opera text vector which is highly related to the question related to the abstract from a vector knowledge base of the Chinese opera text through similarity retrieval matching; and forming LLM language model cue words in combination wi
