Free fact-check service to weed out fake news

Baptist University has become the city's first academic institution to launch a free online fact-checking service against the spread of fake news.
FactCheck Service was launched as half of 1,200 adults interviewed by the university this year said they had occasionally spotted fake news in mainstream media. About 36.8 percent said they had found lots of pandemic-related fake news early this year.
A 12-member research team at the university's School of Communication, consisting of media lecturers, scholars and veteran journalists, ran a pilot scheme of the service in September.
Research assistant professor Stephanie Tsang Tsz-wing said the service consisted of manual fact-checking, crowd-sourcing by obtaining information submitted by the public through the service's mobile app and AI fact-checking.
In manual fact-checking, Tsang said some team members would shortlist keywords of trendy news topics every morning.
"The members would then input the selected keywords into CrowdTangle [an analytics tool] and stream corresponding information from there," she said.
"They will go through at least 2,000 pieces of information every day to identify suspicious content."
Tsang said one of the principles of fishing suspicious content was to see if the information was "checkable." She added: "For instance, information such as the number of people who have tested positive for Covid-19 is checkable."
Tsang said the shortlisted suspicious content would then be handed to other members of the team to carry out fact-checking.
"The fact-checkers will then search for the primary source of the content, contact specialists for advice via alumni networks, interview experts or carry out on-site investigations," Tsang said.
"Later, they will draft fact-checking reports on the content, which will then be vetted by editors and consultants of the team before they can be published online."
She said results of the reports would be concluded by one of four verdicts: "true," "partially true," "false" or "unsubstantiated."
Assistant professor at the university's Department of Journalism, Nick Zhang Yin, said the crowd-sourcing phase - still undergoing beta testing - could alleviate the fact-checking burden on the small team.
"In the long term, we hope to cohere the collective power of society, allowing more members to participate in the fact-checking process via the app," Zhang said. Media professionals will be invited to review the quality of the fact-checking process and user experience.
The AI fact-checking phase is still being developed, which will enable the automatic detection and fact-checking of suspicious content.
