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.

What’s new in Inputlog 9.5?

• Certificate
  The installation procedure is now officially certified (University of Antwerp).
• 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
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).

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).

Inputlog: Korean test version
The Korean version of Inputlog uses the “Korean Input Mode” to optimize the syllable recognition. This mode can be activated in the Windows system. The logging consists of both the keyboard input (syllables, incl. timestamps) and the selected Korean sign.
At the moment the Inputlog analyses are not yet fully adapted to the Korean logging data, but the ‘General analysis’ already provides a detailed basis to set up analyses that suit your research objectives. If you are interested in collaborating on the adaptation of the analyses or the development of new analyses, please, don’t hesitate to contact us.

Precautions for Korean Logging Analysis

• When recording Korean logging, the Windows system must be set to “Korean Input Mode.”
• Prior to running Inputlog, any currently running word processing programs should be closed. Be aware that any concurrently running programs might influence the logging results.
• Among the analysis functions, general, summary (excluding revision-related aspects), linear, source, and pause analyses (excluding syllable-level) are currently available.
• In all Korean logging analyses, the term “word” refers to a space unit.
• The current version is developed using MS-Word 2013. Later versions of Office (e.g., Word for Office 365) might require extra attention.

This Korean version was developed with the support of the Korean Language Education Research Institute at Seoul National University. We appreciate Yanghoon Doh, prof. Dr. Byeonggon Min (Seoul National University), and prof. Dr. Hyeyoun Kim (Dongguk University) for their contributions throughout this process.

Inputlog: Chinese test version

A Chinese version of Inputlog (prototype) was developed to capture Chinese writing processes. The module logs both “Sogou pinyin” input and the resulting Chinese character on the screen.

Warranty: At the moment the Inputlog analyses are not fully adapted to the specific characteristics of Chinese writing. However, the ‘General analysis’ already provides a detailed basis to set up analyses that suit your research objectives.

This module was developed in close collaborations with our colleagues at Shandong University: Prof. Junju Wang (principal investigator) and and drs. Cheng Wei). We also thank prof. Cuiqin Xu (Nanjing University) for all her input.
