title: Smarty4Covid Dataset

description: <strong>Overview</strong> The idea of harnessing the power of Artificial Intelligence (AI) and m-health towards detecting new bio-markers indicative of the onset and the progress of respiratory abnormalities/conditions, has motivated several research endeavours in applying signal analysis and AI on audio recordings of cough, voice and breath with the ultimate goal to detect innovative COVID-19 related bio-markers. The Smarty4Covid dataset contains audio signals of cough, deep breathing and regular breathing as recorded by means of different devices through following a crowd-sourcing approach supported by a responsive web-based application. In addition, it includes self-reported information, such as demographics, symptoms and results of COVID-19 tests.<br> <strong>Data structure</strong> The main directory is organized as shown below. It contains sub-directories, each including the submissions of a specific participant. Each participant directory is named after the unique participant id and it contains a unique json file (“demographics_underlying_conditions.json”) containing information about demographics (e.g. BMI, age group, sex, presence of potential underlying medical conditions). Each submission is contained in a separate sub-directory, inside the participants’ directory, named after the unique submission id and it includes: audio recordings of cough (“audio.cough.mp3”), deep breathing (“audio.breath_deep.mp3”) and regular breathing (“audio.breath_regular.mp3”) a json file (“main_questionnaire.json”) containing the self-reported information related to the COVID-19 test (result, type and date of the test), vaccination against COVID-19 status, COVID-19 related symptoms, vital signs and more. a json file (“breathing_features.json”) containing data from our meta-analysis on the data. Specifically, it contains features, such as breathing rate and time parameters, estimated from the meta-analysis on the breath recordings. It also contains ground truth annotations for the inhale and exhale periods of the breath recordings. four json files (“experts.breath.json”, “experts.cough.json”, “experts.medical_advice.json”, “experts.speech.json”) containing experts’ annotations on 4 data labeling campaigns. Finally, there is also a csv file “smarty4covid_tabular_data.csv”. This file contains any information available for every submission in the dataset. A detailed description of the various JSON files and their fields is provided in "smarty4covid_overview.pdf" file. ├── ...<br> ├── &lt;ParticipantID&gt;<br> │ ├── demographics_underlying_conditions.json<br> │ ├── &lt;SubmissionId1&gt;<br> │ │ ├── audio.breath_regular.mp3<br> │ │ ├── audio.breath_deep.mp3<br> │ │ ├── audio.cough.mp3<br> │ │ ├── main_questionnaire.json<br> │ │ ├── breathing_features.json<br> │ │ ├── experts.breath.json<br> │ │ ├── experts.cough.json<br> │ │ ├── experts.medical_advice.json<br> │ │ └── experts.speech.json<br> │ ├── ...<br> │ └── &lt;SubmissionIdN&gt;<br> │ ├── audio.breath_regular.mp3<br> │ ├── audio.breath_deep.mp3<br> │ ├── audio.cough.mp3<br> │ ├── main_questionnaire.json<br> │ ├── breathing_features.json<br> │ ├── experts.breath.json<br> │ ├── experts.cough.json<br> │ ├── experts.medical_advice.json<br> │ └── experts.speech.json<br> ├── ...<br> ├── smarty4covid_tabular_data.csv<br> ├── smarty4covid_overview.pdf<br> └── readme.xlsx
