One-shot Text Field Labeling using Attention and Belief Propagation for Structure Information Extraction [article]

Mengli Cheng, Minghui Qiu, Xing Shi, Jun Huang, Wei Lin
2020 arXiv   pre-print
Structured information extraction from document images usually consists of three steps: text detection, text recognition, and text field labeling.  ...  To alleviate these problems, we proposed a novel deep end-to-end trainable approach for one-shot text field labeling, which makes use of attention mechanism to transfer the layout information between document  ...  Text detection, text recognition, and text field labeling are the three key steps for structured information extraction [17, 23] .  ...
