Overview - Document Visual Question Answering
The CVPR 2020 "Document Visual Question Answering" (DocVQA) challenge, focuses on a specific type of Visual Question Answering task, where visually understanding the information on a document image is necessary in order to provide an answer. This goes over and above passing a document image through OCR, and involves understanding all types of information conveyed by a document. Textual content (handwritten or typewritten), non-textual elements (marks, tick boxes, separators, diagrams), layout (page structure, forms, tables), and style (font, colours, highlighting), to mention just a few, are pieces of information that can be potentially necessary for responding to the question at hand.
The challenge is organised in the context of the CVPR 2020 Workshop on Text and Documents in the Deep Learning Era.

Contemporary Document Analysis and Recognition (DAR) research tends to focus on generic information extraction tasks (character recognition, table extraction, word spotting), largely disconnected from the final purpose the extracted information is used for. The DocVQA challenge, seeks to inspire a “purpose-driven” point of view in Document Analysis and Recognition research, where the document content is extracted and used to respond to high-level tasks defined by the human consumers of this information. In this sense DocVQA provides a high-level task that should dynamically drive information extraction algorithms to conditionally interpret document images.
On the other hand, Visual Question Answering (VQA) as it is currently applied in real scene images is vulnerable to learning coincidental correlations in the data without forming a deeper understanding of the scene. In the case of DocVQA, more profound relations between the question aims (as expressed in natural language), and the document image content (that needs to be extracted and understood) are necessary to establish.
A large-scale dataset of document images reflecting real-world document variety, along with question and answer pairs will be released according to the schedule on the right.
The challenge will comprise two tasks. On one hand, a typical VQA task, where natural language questions are defined over single documents, and an answer needs to be generated by interpreting the document image. No list of pre-defined responses will be given, hence the problem cannot be easily treated as an n-way classification task. On the other hand, a retrieval-style task where given a question, the aim is to identify and retrieve all the documents in a large document collection that are relevant to answering this question.
