- Abstract summary: We analyze novelty, a measurement of new items that emerge in the top news search results.
We find more new items emerging for election related queries compared to topical or stable queries.
We argue that such imbalances affect the visibility of political candidates in news searches during electoral periods.

- Abstract: The 2020 US elections news coverage was extensive, with new pieces of
information generated rapidly. This evolving scenario presented an opportunity
to study the performance of search engines in a context in which they had to
quickly process information as it was published. We analyze novelty, a
measurement of new items that emerge in the top news search results, to compare
the coverage and visibility of different topics. We conduct a longitudinal
study of news results of five search engines collected in short-bursts (every
21 minutes) from two regions (Oregon, US and Frankfurt, Germany), starting on
election day and lasting until one day after the announcement of Biden as the
winner. We find more new items emerging for election related queries ("joe
biden", "donald trump" and "us elections") compared to topical (e.g.,
"coronavirus") or stable (e.g., "holocaust") queries. We demonstrate
differences across search engines and regions over time, and we highlight
imbalances between candidate queries. When it comes to news search, search
engines are responsible for such imbalances, either due to their algorithms or
the set of news sources they rely on. We argue that such imbalances affect the
visibility of political candidates in news searches during electoral periods.

This work focuses on news coverage of local public policy in the San Francisco Bay Area by the San Francisco Chronicle.
First, we gather news articles, public policy documents and meeting recordings and link them using probabilistic relational modeling.
Second, we define a new task: newsworthiness prediction, to predict if a policy item will get covered.

We use a large dataset of 1.8 million news headlines from major U.S. media outlets spanning from 2014 to 2022.
We quantify the fine-grained thematic discrepancy related to four prominent topics - domestic politics, economic issues, social issues, and foreign affairs.
Our findings indicate that on domestic politics and social issues, the discrepancy can be attributed to a certain degree of media bias.

We analyze three competing factors, two algorithmic (ranking and representativeness) and one psychological (familiarity) that could influence the selection of news articles that appear in search results.
Our results demonstrate the steering power of the algorithmic factors on news consumption as compared to familiarity.
We confirm that Google Search drives individuals to unfamiliar sources and find that it increases the diversity of the political audience to news sources.
