queXF For Linux

queXF is a completely free, platform-independent and open source web-based application implemented in PHP and crafted to perfection as a tool for capturing and reading scanned paper forms that are generated by the queXML software.

In other words, queXF is a CADE (Computer Assisted Data Entry) utility that is capable of processing filled paper forms, including survey questionnaires, generated by queXML. It is designed as an alternative to the Remark OMR and Cardiff Teleform programs.

Key features include support for an unlimited number of operators that can be used for verification, support for importing queXMLPDF forms that have been generated by the Limesurvey application, the ability to accurately guess and automatically detect boxes’ locations on the form without manually overlaying boxes, as well as distributed processing support.

In additions, the software allows users to review forms directly from the Internet, confirming that the data is accurate, integrates with the queXML program, produces ready-to-scan forms, handles isolated characters, recognizes handwriting, and outputs data from forms in various formats, including Labelled CSV, CSV, PSPP (SPSS), DDI, as well as formats with fixed width.

Another interesting feature is the ability to export data post or pre verification stages. Please note that the built-in ICR (Intelligent Character Recognition) engine powers the isolated character handwriting recognition functionality of the application. queXF is a cross-platform utility that can be used on any operating system where a supported web browser (Mozilla Firefox, Google Chrome, Opera, Safari, Internet Explorer) exists.

The queXF software was written entirely in the PHP server-side programming language, which means that it can only be run on a web server, either locally or on a cloud server infrastructure. It should be deployed on a server powered by a GNU/Linux system that runs the Apache web server, but nginx is also supported, as well as IIS.
