Projects / queXF


queXF (pronounced kweks-eff) 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 an alternative to programs such as Cardiff Teleform and Remark OMR, in some situations. It removes the need to manually enter form data, therefore reducing error and fatigue. It does OMR (Optical Mark Recognition) on each form to determine if boxes have been filled, and can use ICR (Intelligent Character Recognition) to determine what characters have been entered into boxes.

Recent releases

  •  09 May 2014 00:22

    Release Notes: Single choice fields with more than one box are now automatically confirmed for the verifier where strictly one box is correctly detected. This should greatly improve productivity of verifiers where there are many single choice fields to verify. Duplicate forms that have not been verified can now be easily deleted using the duplicate form function.

      Release Notes: Page edge detection has been greatly improved. queXF can determine if a page corner has been detected incorrectly and repair it. This should greatly improve page alignment where scans are not ideal.

      •  20 Dec 2013 03:10

        Release Notes: This release fixes a bug in importing where the temporary directory contains spaces. It also adds an "Accept page" feature which verifiers can click to accept all boxes on the page (instead of going through each one). Translations have been updated.

        •  12 Nov 2012 04:40

          Release Notes: This release adds feature enhancements, including better barcode detection and faster verification submits by using POSTs instead of GETs. Bugfixes include fixing an error in CSV output with labelled multiple choice questions. Translations have been updated from Launchpad.

          •  23 May 2012 05:36

            Release Notes: Response values and labels can be added/edited by mousing over response boxes when banding. Bugs with PSPP export, banding file import, and page width detection have been fixed. Translations have been updated from Launchpad.
