Caption association techniques

Abstract

Caption association techniques as part of digital content creation by a computing device are described. The computing device is configured to extract text features and bounding boxes from an input document. These text features and bounding boxes are processed to reduce a number of possible search spaces. The processing may involve generating and utilizing a language model that captures the semantic meaning of the text features to identify and filter static text, and may involve identifying and filtering inline captions. A number of bounding boxes are identified for a potential caption. The potential caption and corresponding identified bounding boxes are concatenated into a vector. The concatenated vector is used to identify relationships among the bounding boxes to determine a single bounding box associated with the caption. The determined association is utilized to generate an output digital document that includes a structured association between the caption and a data entry field.
