The invention discloses a digital semantic understanding and conversion
system and method based on multi-
modal feature fusion, the contribution degrees of three types of features including
semantics, mathematical and context in different digital type recognition are displayed through a multi-
modal feature importance thermodynamic diagram, a macroscopic-microscopic double-layer
classification structure is adopted, error propagation is effectively blocked, and the recognition efficiency is improved. Through three-way cooperation of a
rule engine, a
statistical model and a semantic engine, high-robustness
decision making is realized, and an intelligent conversion routing and grammar
adaptation mechanism is developed for a digital semantic conversion link. The method can effectively solve the technical bottlenecks of insufficient accuracy, poor expandability, strong training
data dependence and the like of a traditional method in complex
number type recognition, and is suitable for multiple application scenes such as TTS voice generation,
natural language generation, financial
document processing, education science and technology and the like; accurate conversion from digital character strings to semantic expressions conforming to
human language habits can be achieved.
