Our tool, Harmony, allows researchers to upload a set of mental health questionnaires in PDF or Excel format, such as the [GAD-7 anxiety questionnaire](https://adaa.org/sites/default/files/GAD-7_Anxiety-updated_0.pdf). It identifies which questions among questionnaires are identical, similar in meaning, or antonyms of each other, and generates a network graph. This allows researchers to harmonise datasets.
Our tool, [Harmony](https://fastdatascience.com/harmony-wellcome-data-prize/), allows researchers to upload a set of mental health questionnaires in PDF or Excel format, such as the [GAD-7 anxiety questionnaire](https://adaa.org/sites/default/files/GAD-7_Anxiety-updated_0.pdf). It identifies which questions among questionnaires are identical, similar in meaning, or antonyms of each other, and generates a network graph. This allows researchers to harmonise datasets.
Uniquely, Harmony relies on [Transformer neural network architectures](https://deepai.org/machine-learning-glossary-and-terms/transformer-neural-network) and is not dependent on a dictionary approach or word list. This allows for multilingual support (English and Portuguese are our languages of focus), and Harmony is able to correctly map the GAD-7 used in the UK to the [GAD-7 used in Brazil](https://pesquisa.bvsalud.org/portal/resource/pt/lil-788637), despite the Brazilian questionnaire being in Brazilian Portuguese.

This allows for [multilingual support](/harmony-supports-over-8-languages/) (English and Portuguese are our languages of focus), and Harmony is able to correctly map the GAD-7 used in the UK to the [GAD-7 used in Brazil](https://pesquisa.bvsalud.org/portal/resource/pt/lil-788637), despite the Brazilian questionnaire being in Brazilian Portuguese.
Using Harmony, our team was able to conduct groundbreaking research into social isolation and anxiety with NLP supplying a quantitative measure of the equivalence of the different mental health datasets.
