Before you proceed

Inputlog versions
The latest version and previous releases of Inputlog are freely downloadable for (academic) research purposes. We strongly recommend you to carefully read the installation instructions before you register and install the software on your computer.

Manual and Documentation
The user manual and some fact sheets that document the use of the different components in Inputlog are made available. These documents also provide more background on the rationale that is used in the analyses, and they explain the algorithms that are used in the different analyses.

Versioning What’s new in Inputlog 9.5?

  • Versioning
    In the settings you can indicate that the logger saves a version of the text produced so far, every x minutes. This allows for intermediate text comparison..
  • Copy task integration
    A direct link has been made available to the Inputlog copy task (see Record tab).
  • Pause analysis
    The algorithms we use to identify the pause location and to calculate between word/sentence/paragraphs have been further refined. Also, the operationalisation and characterisation of the P-burst has been further improved..[see also ‘fact sheets’ on the website]
  • Source analysis
    The source segmentation and characterisation has been further improved, explicitly focusing on the different scenarios writers use to activate and switch between the main document and the sources (e.g., use of the taskbar).
  • Technical bugs
    Several bugs have been resolved. Thank you to everyone who informed us about bugs (or other issues) and helped us  addressing these.
    The bug with the most impact related to the fact that when the MS Word (main document) was deactivated by using the minimize-icon (right top corner) the logger did not render updates of the document length so far, nor of the cursor position. This also affected the revision analysis.
  • Internet explorer
    Analysis files (xml-format) should be opened with Internet Explorer. If you are using Edge, be sure to activate Internet Explorer, e.g., using this instruction.

Inputlog Edu-version

December 2023

Inputlog Edu-version
To facilitate the use of Inputlog in the classroom, we have developed a ‘minimal’ version of Inputlog, the so called Edu-version. This version has a simplified interface which only focuses on ‘Recording’ a writing process and ‘Generating’ a user friendly feedback report.

This version of Inputlog was co-developed within the LIFT project (NWO, The Netherlands – University of Antwerp).

version 0.9.1

March 2024

Inputlog-LibreOffice version 0.9.1
To facilitate logging in Libre Office we developed  “Inputlog-LibreOffice”. Its main advantage is that this Open source professional word processor allows for better control of the logging, compared to, for instance,  logging in Ms Word. The current variant of Inputlog was developed as a  Libre Office extension (a certified add-in for the program). Its sole purpose is to log the writing process as detailed as possible. However, as the resulting logfile is an IDFX-file, the general analysis and the pause analysis of the Inputlog standard version can be used to explore the logdata.
You can find a description of the installation procedure and a user guide of Inputlog LibreOffice below (see Documentation section).

This keystroke logging application was developed within the project Track Changes (NWO, The Netherlands – Huygens Institute and University of Antwerp).
