  Expert Recommendation in Fact-Checking

To enhance the ability to find credible evidence in news articles, we propose
a novel task of expert recommendation, which aims to identify trustworthy
experts on a specific news topic. To achieve the aim, we describe the
construction of a novel NewsQuote dataset consisting of 24,031 quote-speaker
pairs that appeared on a COVID-19 news corpus. We demonstrate an automatic
pipeline for speaker and quote extraction via a BERT-based Question Answering
model. Then, we formulate expert recommendations as document retrieval task by
retrieving relevant quotes first as an intermediate step for expert
identification, and expert retrieval by directly retrieving sources based on
the probability of a query conditional on a candidate expert. Experimental
results on NewsQuote show that document retrieval is more effective in
identifying relevant experts for a given news topic compared to expert
retrieval
