Core Processing Capabilities of Versatile OCR Program
As an OCR tool designed for academic scenarios, Versatile OCR Program realizes accurate extraction of complex document elements through multi-technology fusion. Its core value is reflected in five dimensions of processing capabilities: text class supports English/Japanese/Korean multi-language recognition; formula class can convert mathematical expressions into LaTeX codes and natural language descriptions (e.g., quadratic equation explanations); table class maintains complete extraction of rows and columns of structures; chart class generates semantic annotations that contain data point analyses; and schematic class provides descriptions of phases in biology and other specialized fields (e.g., the cell division process). Compared with other general-purpose OCR tools, it adopts the technology combination of DocLayout-YOLO+Google Vision API+MathPix, which can achieve an accuracy rate of 90-95% when dealing with real academic datasets, such as the East University Mathematics Examination Papers, and has a significant advantage in the recognition of formula-intensive passages in particular.
