queXF is a tool that takes scanned paper forms generated using queXML and reads them. Operators can then verify that queXF has read the form correctly. Once this is done, the data collected can be exported in a fixed width ASCII file with a DDI data description.
queXF can be used as a web based, Open Source alternative to programs such as Cardiff Teleform and Remark OMR, in some situations. It can be used as a CADE (Computer Assisted Data Entry) tool.
queXF removes the need to manually enter form data, therefore reducing error and fatigue. queXF does OMR (Optical Mark Recognition) on each form to determine if boxes have been filled, and can use Tesseract OCR to determine what characters have been entered in to boxes.
Operators need little knowledge of the form design as queXF breaks down the verification task in to a question by question process. The operator works in a web browser and does not need to install any other software on their computer, therefore can work from any location with network access.
queXF is Open Source and only relies on other Open Source packages to operate.
