Do you need to compare questionnaire data across studies? Are the items inconsistent, or are there different versions of the same questionnaire floating around? Do you have questionnaires written in different languages that you would like to compare?
Harmony is a data harmonisation project that using Natural Language Processing to to help researchers to make better use of existing data from different studies by supporting them with the harmonisation of various measures and items used in different studies. Harmony is a collaboration project between Ulster University, the Centre for Longitudinal Studies at UCL and Universidade Federal de Santa Maria in Brazil, and Fast Data Science Ltd.
Harmonise questionnaire items
Harmony is a data harmonisation project that uses Natural Language Processing (NLP) to help researchers make better use of existing data from different studies. It can be used to compare questionnaire data across studies, even if the questionnaires are written in different languages.
Harmony first extracts the questions from each questionnaire. It then uses NLP techniques to compare the questions and identify their semantic similarity. This allows Harmony to match questions from different questionnaires, even if they are not worded identically.
To use Harmony, you first need to upload the questionnaires you want to compare to the Harmony website. You can upload PDF or Excel files. Harmony will then automatically extract the questions from the files and start matching them.
You can then review the matches that Harmony has made. If you disagree with a match, you can easily remove it. You can also adjust the sensitivity of the matching algorithm to make it more or less strict.
Once you are satisfied with the matches, you can export the harmonised data to Excel.

What is NLP in business environments? Natural language processing (NLP) is a branch of AI (Artificial Intelligence), empowering computers to not just understand but also process and generate language in the same way that humans do.
