<p>Correlation between search terms, infection cases, and media mentions.</p>
Listed in DMU Figshare and UCL Research Data Repository — shown once because both records carry DOI 10.1371/journal.pone.0358063.g003
<p>a) and b) show the Pearson correlation between each cluster and infection cases (left) and media mentions (right) during the pandemic period for both the flu (top) and COVID-19 (bottom).
Description
In contrast, c) and d) present the Linear Regression model’s <i>R</i><sup>2</sup> performance. The asterisks represent the p-value of a <i>t</i>-test with the null hypothesis that mean correlation is zero (*0.01 < <i>p</i> < 0.05; **0.001 < <i>p</i> < 0.01; ***<i>p</i> < 0.001; ns <i>p</i> > 0.05).
In a) and b), correlations can be both positive and negative, indicating whether search volumes increase or decrease with cases or media mentions. In c) and d), however, only the absolute correlation values are considered, as predictive power depends on correlation strength rather than direction. Also, c) and d) illustrate the cumulative contribution of individual search terms to the model’s performance.

Terms are added sequentially from the most to the least correlated with infection cases (left to right, in <i>Cases</i> panels) and from the least to the most correlated with media mentions (left to right, in <i>Media</i> panels). The black line represents the Linear Regression <i>R</i><sup>2</sup>, showing how predictive performance evolves as new terms are added, while the dashed line shows the <i>R</i><sup>2</sup> obtained for C1 as a reference.
We focus on the Linear Regression model here as it provides a more interpretable baseline for assessing the contribution of different feature sets. The colors of the vertical bars correspond to the clusters each term belongs to, allowing a comparison of cluster contributions.</p>
