Abstract
Techniques for automated form understanding via layout-agnostic identification of keys and corresponding values are described. An embedding generator creates embeddings of pixels from an image including a representation of a form. The generated embeddings are similar for pixels within a same key-value unit, and far apart for pixels not in a same key-value unit. A weighted bipartite graph is constructed including a first set of nodes corresponding to keys of the form and a second set of nodes corresponding to values of the form. Weights for the edges are determined based on an analysis of distances between ones of the embeddings. The graph is partitioned according to a scheme to identify pairings between the first set of nodes and the second set of nodes that produces a minimum overall edge weight. The pairings indicate keys and values that are associated within the form.
