4 May 2021, Geneva – WHO and UN Global Pulse, the
Secretary-General’s digital innovation initiative are embarking today on a new venture to analyse content shared on public radio across the
African continent to support infodemic monitoring. Part of the wider infodemic management programme, this collaboration will integrate radio data analysis into monitoring
tools to inform the infodemic response by including more voices of
vulnerable populations.
Radio remains one of the most reliable and affordable ways of accessing and sharing information with some 44,000
stations worldwide as reported by UNESCO. People discuss everything from the light-hearted to the serious, including the effects COVID-19 is
having on them, their families, and their communities. Often, opinions
expressed in radio talk shows include first-hand accounts of incidents,
and mis- and disinformation reported by citizens that may not be
recorded elsewhere.
“Listening to and understanding
the concerns and questions of communities is pivotal in every health
emergency to help us shape our risk communication interventions. This
tool will be a key addition to our infodemic toolbox,” says Dr Sylvie
Briand, Director WHO Global Infectious Hazards Department.
UN
Global Pulse has worked on various projects to convert radio speech into text for vernacular languages and to analyse the information to
understand perceptions. This collaboration will expand that scope by
developing methods to capture and analyse content on topics that discuss COVID-19 and vaccination efforts across Africa.
“As we develop
new methodologies and deploy new tools, we want to give public health
officials the most useful insights and create new scientific evidence so the field of infodemic management continues to build solid
foundations,” says Miguel Luengo-Oroz, Chief Data Scientist at UN Global Pulse.
The project is already off the ground with pilot studies
to analyse information related to vaccines. In the coming months, the
plan is to integrate more than 100 public radio stations and develop a
custom-built monitoring and analysis dashboard that will allow public
health officials, infodemic managers, and fact checking organizations to track changing questions and concerns, including mis- and
dis-information, to gather insights that can inform public health
decisions.
The methodology will account for potential algorithmic biases along the AI analysis pipeline, and the project will implement data privacy instruments developed by UN Global Pulse to mitigate the potential risks and harms associated with this technology.
By incorporating languages and voices that may often be excluded from
official reporting and analysis, this effort aims to de-marginalise
communities by better understanding their changing needs in public
health emergencies.
“In many places in Africa the digital divide
is still very much a reality,” adds Luengo-Oroz. “We’re building a tool
that leverages public radio to include more voices of citizens in
decision-making about where to focus our efforts and how to mitigate the dangers of this infodemic.”
In future, custom language models
could be built to incorporate a wider variety of languages and dialects
spoken, and support routine social listening of radio narratives as a
way to continue strengthening accountability to affected populations for global health.
